INTRODUCTION

Kotler (1973) defines atmospherics as “the conscious designing of space to create certain buyereffects, specifically, the designing of buying environments to produce specific emotional effects inthe buyer that enhance purchase probability.” Given the extended increasing of online stores, someauthors are focusing their research on studying an “extended” term: Web atmospheric, also calledwebmosphere by Childers et al. (2001), or virtual store atmosphere by Vrechopoulos et al. (2000),or online store environment by Manganari et al. (2009). This concept is defined by Dailey (2004)as “the conscious designing of web environments to create positive effects (e.g., positive affect,positive cognitions, etc.) in users in order to obtain more positive responses (e.g., site revisiting or

browsing). When marketers design web interfaces in order toentice consumers, they are utilizing web atmospherics.”

Childers et al. (2001) explain that the use the use of video,images, humor, color, music, and other interactive aspects candefine and hedonic experience and help to create a moreenjoyable environment. On the contrary, a technology orientedperspective that focus on shopping as a cold information systems,with no enjoyable environments, is probable to be decreased,specially for products with hedonic attributes (Hirschman andHolbrook, 1982; Childers et al., 2001; Solaymani et al., 2012).

Most authors use the Stimulus-Organism-Response (S-O-R)paradigm proposed by Mehrabian and Russell (1974) to explainthe influence of web atmosphere on consumers. These authorssuggest that external stimulus (like web atmospheric cues) affectconsumers’ internal states and, in turn, they have an effecton behavioral responses. In the online shopping environment,some researchers use actual stimuli (Wang et al., 2010; Animeshet al., 2011; Kim and Lennon, 2013), and others use customerassessments of the stimuli to denote the stimulus segment of themodel (Nath, 2009; Koo and Ju, 2010; Manganari et al., 2011).Eroglu et al. (2001, 2003) proposed two types of webmosphericcues which named high and low task relevant cues. High task-relevant cues comprise verbal or pictorial contents directlyassociated with the shopping goal. The purpose of these verbalor pictorial descriptions (e.g., product information, price, anddelivery and return policies) is to assist online consumers to reachtheir shopping goals. Low task relevant cues, on the other hand,are peripheral contents (e.g., color, background patterns, andimages) not directly related to the shopping goals. Moreover, theorganism (i.e., user’s internal states of S-O-R model) is composedby affective, cognitive and satisfaction variables (Oliver, 1997;Bigné and Andreu, 2004). In addition, Eroglu et al. (2001, 2003)suggest that the internal states of the organism include affectand cognition and that satisfaction is one of the outcomes ofbehavior. And, finally, the response (i.e., behavioral responses ofS-O-R model) refer to website patronage intention (Jeong et al.,2009), purchase intention (Hsu et al., 2011; Liu et al., 2016), andintention to use and buy (Huang, 2013).

Many studies do not examine specific webmosphere stimuliseparately and their impact on internal and behavioral responses.Normally, these studies analyze global stimuli such as highand low task relevant cues (Eroglu et al., 2001, 2003) andtheir impact on consumer. Other authors use only one webstimulus like navigation structure (Dailey, 2004) including someaspects referred to web navigation. Other studies analyze specificstimuli attending to other online marketing variables such asprice, service quality, social variables, etc. (Chang et al., 2011;Nesset et al., 2011), not focusing the research toward webdesign exclusively. Moreover, some previous research analyzesbehavioral responses such as purchase intention against realshopping (although through simulation). Previous research doesnot examine the relationship between three mediator variables.Some authors analyze perceived risk or trust (Kim, 2012),or product involvement (Keng et al., 2012), or atmosphericresponsiveness (Eroglu et al., 2001). Nevertheless, any studyanalyzes the possible relationship and impact of three constructson internal and behavioral online buyer responses.

Thus, the main objective of this study is to establishthe main different effects of two webmosphere verbalcommunication stimulus (i.e., navigation structure) andnon-verbal communication stimuli (i.e., music and presentationof products), on internal (i.e., satisfaction, cognitive andaffective) and behavioral consumer responses (i.e., approachresponses and real shopping outcomes) within a virtual apparelshopping environment. Moreover, three mediator variables (i.e.,involvement, atmospheric responsiveness, and perceived risk)are considered in the study in order to analyze the impact ofthem on the relationships between webmospheric cues and userresponses.

Specifically, affective state refers to emotions that user feelstoward different stimuli (Eroglu et al., 2001, 2003). Cognitivestate is the thought processes and state of mind related to theacquisition, processing, retention, and retrieval of information(Eroglu et al., 2001). Satisfaction is understood as a globalevaluation or attitude that evolves over time resulting from arelationship between store and consumer (Flavián et al., 2004).Approach behaviors refer to all positive actions that might bedevelop toward a setting, for example, intentions to exploreor stay, while avoidance refers to the opposite (Mehrabianand Russell, 1974; Bitner, 1992; Gregg and Walczak, 2010).Real shopping outcomes are considered as behavioral contumerresponses. This construction refers to quantitative measures suchas time or money spent, products bought, etc.

Regarding mediator variables, involvement refers to thesignificant consciousness produced from product characteristics(Zaichkowsky, 1986). Atmospheric responsiveness is anenvironmental characteristic that influences users’ decisions onwhere and how to shop as well as the outcomes of the shoppingexperience (Eroglu et al., 2001, 2003). And, finally, perceived riskis the consumer’s level of uncertainty regarding the outcome of apurchase decision.

Respect to navigation structure, we propose compare twoweb manipulatios: “Free navigation structure” of the web sitemeans that consumer can move easily through the web site (i.e.,navigational bars and the same links to access the informationin all sites, location link, and searching tool) and, consequently,the user is not controlled by web marketer with restrictivenavigational bars. In contrast, in a web site with “hierarchicalnavigation structure,” the user only can use the “next” and“previous” navigational bars to move through the web site(i.e., user is exposed to restrictive navigational bars and, inconsequence, its navigation is more difficult). Regarding musicstimulus, we propose compare two web manipulations: Website“with music” versus website “non-music.” Finally, respect to“presentation of products” stimulus, we propose compare twoweb manipulations: “Moving images” (movement of photos in360◦, video, etc.) versus “static images.”

“One important feature of the new media that differs fromtraditional shopping channels is the absence of the experienceabout the online store visit and the unfeasibility of examininga product prior to purchase” (Lorenzo et al., 2007). Alba et al.(1997) indicate that a competitive advantage for marketers canbe lead through an effective design of web site. But, how canmarketers design web interfaces with high level of effectivity?

Lorenzo-Romero et al. An Empirical Analysis

Web atmospherics may offer insight into this question (Dailey,2004).

Hoffman and Novak (1996) define network navigation as“the process of self-directed movement through the mediainvolving non-linear search and retrieval methods that permitgreater freedom of choice.” In traditional retail environments,consumers identify the spatial representations of the store’sdesign and recognize how products are grouped by theircommon characteristics or through orientation aids (i.e., displays,directory maps, store personnel, aisle markers, and so on) whenthey look for products (Titus and Everett, 1995).

Within the context of online behavior, we can introduce theusability concept. According to Nielsen (2000), the usability refersto the facility for the online navigation, and users are satisfiedwhen it is easy to use by them. Therefore, usability is a qualityattribute, and a key attribute to reach consumer satisfaction(Ranganathan and Ganapathy, 2002).

Dailey (2004) analyzes the impact of restrictive navigationcues as an explicit online webmosphere variable. She based onthe theory of flow experience and the psychological reactance toexplain that the restrictive navigation cues act as barriers thatmake users to be threated about the control over web navigation.This perceived barrier causes negative attitudes toward the website and an avoidance behavior, which has negative consequencesfor the web marketer.

As other authors affirm, an easy navigational structure, suchas a high task relevant (Eroglu et al., 2003), ease of use andusefulness (Childers et al., 2001), has a positive effect on theinternal and behavioral consumer responses. Therefore, wepropose the following hypothesis:

H1−1: An online shopping web with “free navigation structure”will affect in a more positive affective responses of users than“hierarchical navigation structure.”

The cognitive state in an online shopping refers issues relatedwith how online consumers understand information provided onthe screen to choose from different sites and products and theattitude toward the online store (Eroglu et al., 2003). Therefore,we considered the cognitive state as the consumers’ attitude andthe knowledge attained during the shopping experience. So, wepropose the following hypothesis:

H1−2: An online shopping web with “free navigation structure”will affect in a more favorable cognitive responses of users than“hierarchical navigation structure.”

Taking into account the double perspective of satisfactionmeaning commented in Section “Sample and Procedure:Computer Experimental Design,” our research is focused on theattitudinal satisfaction perspective because it is more relatedto the purchase intention (Shankar et al., 2003). Specifically,satisfaction is understood as a global evaluation or attitude asa result of relationships between store and consumer (Flaviánet al., 2004). For this reason, we will consider the satisfaction asan internal state which is affected by usability. So, the followinghypothesis is proposed:

H1−3: An online shopping web with “free navigation structure”will influence on higher levels of satisfaction of users than“hierarchical navigation structure.”

Donovan et al. (1994) and Sherman et al. (1997) foundthat, in traditional contexts, the shoppers’ environmentalperceptions affected their approach behaviors in the form oftime and money spent, returning, store exploration, and so on.Lorenzo et al. (2007) observe that “within the online shoppingenvironment, some works obtains similar approach/avoidancebehavior depending on the perceived “store” environment andthe mediating effects of individual traits and internal states(Eroglu et al., 2003).” In online environments, these effects havebeen less studied but literature indicates online atmospheric cuesaffect approach/avoidance responses. However, the relationshipbetween both dimensions (i.e., stimuli and behavioral responses)is mediated by internal states for two cases: (a) For onlineenvironments with only utilitarian elements (Dailey, 2004);(b) and for online environments with utilitarian and hedonicelements (Childers et al., 2001; Eroglu et al., 2001, 2003). Havinginto consideration these above literature, we suggest the followinghypothesis:

H1−4: An online shopping web with “free navigation structure”will affect in a more approach responses of users than“hierarchical navigation structure.”

Flavián et al. (2005) demonstrated a positive influence ofweb site usability on real shopping outcomes toward web site(mediated by confidence and satisfaction). In consequence, thefollowing hypothesis is proposed:

H1−5: An online shopping web with “free navigation structure”will influence on more positive real shopping outcomes than“hierarchical navigation structure.”

On the other hand, music in the website is other non-verbalweb technology stimulus. McMurray et al. (2008) argue that intraditional environments musical expectancy can influence onlower-level perceptual processes. Lorenzo et al. (2007) indicatethat “creating a more enjoyable environment may require the useof more powerful web languages, and the inclusion of images,video, color, humor, sound, music, games, animation, and allof the other interactive aspects that could define an enjoyableexperience. A technology oriented perspective that attempts totreat media shopping as cold information systems, rather thanimmersive, hedonic environments, is likely to be misguided,mainly for products with strong hedonic attributes, as can be thecase of apparel (Childers et al., 2001).”

Eroglu et al. (2001, 2003) explain that sounds or music arelow task-relevant cues, since they do not affect in a direct waythe realization of the task. Nevertheless, music or sounds canhelp to create an atmosphere that has the possibility of makingthe shopping experience more pleasurable. In consequence, wepropose the following hypothesis:

H2−1: An online shopping web with music will influenceon more positive affective responses of users than a webenvironment without music.

Lorenzo-Romero et al. An Empirical Analysis

Low task-relevant cues affect positively users’ cognitive statesin online environments (Eroglu et al., 2001). In the literaturethere are several low-task relevant cues, but we will focus in musicand its effect on users’ cognitive states (learning/knowledge andattitudinal process). Therefore, related with cognitive responses,the following hypothesis is proposed:

H2−2: An online shopping web with music will influenceon more favorable cognitive responses of users than a webenvironment without music.

Customer’s satisfaction is defined as “a relative psychologicalstate which is a result of purchase/consumption experience”(Vanhamme, 2000). Most of research demonstrate that storeatmosphere influence on satisfaction and, in turn, behavioralresponses (Bigné and Andreu, 2004) and, specifically, withhedonic webmosphere stimuli (Childers et al., 2001). So, wesuggest the following hypothesis:

H2−3: An online shopping web with music will influence onmore satisfaction of users than a web site without music.

In some studies where consumers were exposed to differenttempo of background music within supermarkets, they obtainedsimilar responses (Milliman, 1986; Oakes, 2003). Eroglu et al.(2001, 2003) demonstrated that consumers behave in differentways (approach/avoidance behaviors) depending on the onlineperceived store environment and the mediating effects ofconsumer internal states. They analyzed whether the online storeinformation and the low-task relevant cues facilitate or impedethe attainment of shopping goals and, in turn, whether theonline shopper exhibited positive or negative behaviors towardthe particular web site. Finally, they obtained that a rise ofsome atmospheric cue (high or low cue) increased the approachresponse of consumer. Because our intention is focused on studyof specific atmospheric cue (i.e., music), we propose the followinghypothesis:

H2−4: An online shopping web with music will affect in moreapproach responses of users than a web site without music.

Finally, regarding behavioral responses we proposed thefollowing hypothesis, attending two groups of variables analyzed(loyalty and approach/avoidance behavioral). Specifically, asregards users’ loyalty toward online store after their visit inthe web site is measured by Eroglu et al. (2003) as satisfactionmeasurement. However, according to above works, loyalty isconsidered as the consequence of the satisfaction (Zeithaml et al.,1996; Bigné and Andreu, 2004; Flavián et al., 2004) and loyaltymeans recommended the online store, better results, etc. Inspite of this conceptual difference, the most works posit thatatmospheric cues (specifically, low-task relevant cues accordingto Eroglu et al. (2001, 2003) affect positively real shoppingoutcomes toward store, although this relationship is mediated byconsumers’ internal states. Taking everything into account, wesuggest the following hypothesis:

H2−5: An online shopping web with music will affect in morepositive real shopping outcomes than a web site without music.

Other non-verbal web technology stimulus, specificallyhedonic dimensions, can be the presentation of product.According to Lorenzo et al. (2007), there are three kindsof animations depending on the technical characteristics thatthey use: animated gifs, flash format and video. In addition,Lorenzo et al. (2007) indicate that “the use of images and theiranimations as design elements within stores offers advantages anddisadvantages depending on their use [. . .]. Animating imageshas a potential effect on human’s periphery vision, specifically;it is very difficult to concentrate on reading a text if there is arevolving logo on the web page. In this case, it is more convenientto reduce the use of animations. However, if animation is used tomake the purchase task easier, the use of animation will be moreconvenient.”

Schlosser (2003) examines how users process the images andtexts offered by virtual media and state that “the image processingrepresents with a more relevant magnitude the object’s interactiveeffects on user intention –purchasing or browsing– than theprocessing of a verbal or in written speech. In fact, internalstates as satisfaction variable is affected positively by animationelements on the website” (Childers et al., 2001; Eroglu et al., 2001,2003; Adelaar et al., 2003; Wang et al., 2010).

The presentation of virtual products with animation designinfluence positively on consumer’s internal states and shoppingoutcomes (Dahan and Srinivasan, 2000; Eroglu et al., 2003;Koernig, 2003; Yoh et al., 2003; Hong et al., 2004; McKinney,2004; Choura and Saber, 2005; Wang et al., 2010; Lian, 2011).In addition, Adelaar et al. (2003) demonstrated that verbal andvisual presence –through the use of image and/or video– improveusers’ emotional states. Therefore, we propose the followinghypothesis:

H3−1: An online shopping web with “moving images” willaffect in more positive affective responses of users than a webenvironment with “static images.”

In a similar vein, the introduction of “low task relevantcues” within the website, such as animation elements, influencefavorable on consumer internal states (Dahan and Srinivasan,2000; Childers et al., 2001; Eroglu et al., 2003; Hong et al., 2004).Moreover, Nielsen (2000) states that animations are efficaciouswhen their transitions allow users to control them by perceptivesystem. So, the hypothesis proposed is:

H3−2: An online shopping web with “moving images” willinfluence on a more favorable cognitive responses of users thana web environment with “static images.”

The two-dimensional structure of a computer screen makes itdifficult to understand a three-dimensional structure with onlyone image, regardless of its quality. So, animation is used to makethe understanding of product’s spatial visualization which theusers observe within the store easier. In this line, Hong et al.(2004) focus their research on the analysis of the use of Flash R©

format on e-consumer behavior. As a result, the animation canincrease the search for information if the animated element isrelevant to the search task. Furthermore, Eroglu et al. (2003)state that the inclusion of this web attribute within the store

facilitates the users’ information processing during the onlinepurchase which, in turn, improves their satisfaction (McKinney,2004). A lot of apparel websites lacks of movement of productsand, even, static images, using in consequence only somedescriptions about products. So, in order to analyze this type ofweb atmosphere cue, this research is focused in the comparisonof static images versus a combination of eight pictures which offeran optical illusion of movement as well as the use of streaming.

The literature offers some works related to the relationshipbetween web atmosphere and satisfaction. For instance, Childerset al. (2001) compared two types of web environments: oneof them included only utilitarian elements (i.e., order andreception system) and the other one included also somehedonic characteristics (i.e., images of products with highresolution, background music, and interactive plays). Grobelnyand Michalski (2015) also use an experimental study to analyzethe influence of hedonic stimuli (color) on user men and womensatisfaction. From Technology Acceptance Model, these authorsobtained that both web dimensions have an equal role in thedevelopment of consumer’s attitudes and behavioral. In thissense, studies such as Eroglu et al. (2001, 2003) and Adelaar et al.(2003) also used different web experiments in their researches.From S-O-R Model, these authors obtained similar results (i.e.,web elements such as images, and video, affect positively oninternal and behavioral responses). In contrast, Kim and Stoel(2004) used the Loiaconno’s WebQualTM instrument to measurethe effects of website quality dimensions (i.e., entertainment, webappearance, transaction capability, response time, informationalfit-to-task, and trust) on shopper satisfaction. These authorsobtained that only three dimensions (specifically, responsetime, transaction capability and informational fit-to-task) wereimportant predictors of consumer satisfaction. To sum up,according to literature, animation elements of the web site affectpositively on internal states, such as satisfaction (Childers et al.,2001; Eroglu et al., 2001, 2003; Adelaar et al., 2003; Hong et al.,2004). So, we proposed the following hypothesis:

H3−3: An online shopping web with “moving images” willinfluence on higher levels of satisfaction of users than a webenvironment with “static images.”

Schlosser (2003) examines how the users process the textsand images offered by online media, and demonstrate that “theimage processing represents with a more relevant magnitudethe object’s interactive effects on user intention –purchasingor browsing– than the processing of a verbal or in writtenspeech. So, the product’s interactivity causes intense mentalimages which will influence more strongly on user’s intentionthan in their cognitive processing” (Lorenzo et al., 2007). Inthe same line, Childers et al. (2001) state that the functionalaspects such as usability, navigational structure, etc., cause stronginfluences on the e-consumer responses. Moreover, the restof web elements not functional such as music, color, imageswith high resolution, etc., are equally relevant elements whichcontribute to the shaping of consumer attitudes and behavior(i.e., opinions about the store and unexpected purchase behavior).Based on previous literature, in webs which includes animations,

costumer’s show more positive internal states, which improvetheir shopping experience and, in consequence, their approachresponses. Having into consideration the above literature, wepropose the following hypothesis (Lorenzo et al., 2007):

H3−4: An online shopping web with “moving images” willaffect in more approach responses of users than a webenvironment with “static images.”

Eroglu et al. (2003) argue that the inclusion of entertainmentwithin the store raises the consumer’s positive behavior towardthe website. On the other hand, Koernig (2003) affirms that thehigher the product’s tangibility level represented through thescreen, the more positive behavioral response. Khakimdjanovaand Park (2005) affirm that the use of online visual displayfeatures that allow viewing the garment from different angles canhelp potential online consumers to make a purchase decision.

In conclusion, according to literature, the use of animationdesigns for presenting products influence positively onconsumer’s internal states and shopping real outcomes (Dahanand Srinivasan, 2000; Adelaar et al., 2003; Eroglu et al., 2003;Koernig, 2003; Yoh et al., 2003; Hong et al., 2004; McKinney,2004; Choura and Saber, 2005). In addition, Argyriou (2012)demonstrated that website characteristics do not affect revisitintentions directly but through the vividness of mental imagesthat consumers hold of the website as a whole. Vivid mentalwebsite imagery is stimulated by animation and facilitated byindividual tendencies to put faith in intuitive rather than rationalthinking. Then, it is proposed that (Lorenzo et al., 2007):

H3−5: An online shopping web with “moving images” willaffect in more positive real shopping outcomes than a webenvironment with “static images.”

Regarding mediator variables, Baron and Kenny (1986)analyze the differences between the properties’ mediator andmoderator variables. In general, mediator variables explainhow external physical events take on internal psychologicalsignificance. Whereas moderator variables specify when certaineffects will hold, mediators speak about how or why sucheffects occur (Lorenzo et al., 2007). Taking into account thisdistinction, in this research were studied three variables (i.e.,involvement, atmospheric responsiveness, and perceived risk) aspossible mediator between constructions analyzed.

Based on Eroglu et al.’s (2003) work, the relationshipbetween virtual atmosphere and internal states is mediated byuser personal characteristics (e.g., involvement and atmosphericresponsiveness).

Zaichkowsky (1986) defines product involvement as therelevant consciousness caused by product characteristics.Moreover, according to Goldsmith and Emmert (1991), thehigher the level of product involvement, the higher the searchfor product information. Therefore, product involvement is animportant variable in consumer behavior.

Then, variables such as involvement with the product (Kenget al., 2012), and specifically with virtual purchase (Hernándezet al., 2010), experience with the new media and advertisement(Fortin and Dholakia, 1999), should affect electronic shopping

In fact, atmospheric responsiveness isan environmental characteristic that influences consumers’decisions -where and how to shop- as well as the shoppingexperience (Eroglu et al., 2001, 2003). Lorenzo et al. (2007), basedon Huang’s (2006) research explain that “flow and involvementare known as motivational constructs (Csikszentmihalyi, 1975).The concept behind involvement lies in personal relevance,regardless of whether the locus of personal relevance residesin the consumer or the situation (Celsi and Olson, 1988).Enduring and situational involvement differ in aspects such as thetemporal pattern of occurrences, the motivations and the benefitssought (Huang, 2006). Enduring involvement is intrinsicallymotivated, whereas situational involvement is extrinsicallymotivated (Kapferer and Laurent, 1985). So, consumers who areenduringly involved are looking for hedonic benefits, whereasconsumers who are situational involved are engaged in goal-directed behaviors (Hoffman and Novak, 1996).”

Otherwise, perceived risk also influence on consumer behaviordepending on web stimulus (Yoh et al., 2003; Smith andSivakumar, 2004; Park and Stoel, 2005), so it is considered as amediator variable. Koernig (2003) affirm that if the tangibility ofthe service is increased in the online environment, the perceivedrisk related to the activity will decrease. In addition, Slovicet al. (1980) argue that the presence of images with low qualitywithin virtual stores cause a negative influence on consumerbehavior, and also it will increase the perceived risk. On theother hand, Chang and Wu (2012) study the effect of perceivedrisk by analyzing the moderating effects of decision-makingstyle, it means involvement or heuristics, in the virtual context,obtaining that perceived risk toward a website influences onpurchasing intention through cognition, and this affects onattitudes. Within this line, Keng et al. (2012) analyzed themoderating roles of needing for touching and implication withthe product.

Based on previous literature, four additional hypotheses foreach three webmosphere analyzed stimuli are proposed respectto mediator variables –two of them related to involvement– asfollow (a: Navigational structure; b: Music; c: Presentation ofproducts):

H4a,b,c: Involvement with apparel will have a positivemediator effect between the three different web stimuli (i.e.,music, navigational structure and presentation of products)and online user responses (i.e., internal and behavioralresponses)H5a,b,c: Involvement with virtual shopping will have a positivemediator effect between the three different web stimuli andonline user responsesH6a,b,c: Atmospheric responsiveness will have a positivemediator effect between the three different web stimuli andonline user responsesH7a,b,c: Perceived risk will have a positive mediator effectbetween the three different web stimuli and online userresponses

To test above hypotheses, an extended model is proposed(Figure 1) based on the S-O-R paradigm. The direct effects

between specific web technological attributes related to non-verbal (i.e., hedonic: music and visualization of products)and verbal (i.e., utilitarian: navigational structure) webdimensions on online user responses (i.e., internal states andbehavioral responses) were analyzed, as well as examining theinfluence of mediator variables (i.e., involvement, atmosphericresponsiveness, and perceived risk) between both constructs (i.e.,web stimuli and online user responses).

MATERIALS AND METHODS

Sample and Procedure: ComputerExperimental DesignA 2 (“free” versus “hierarchical” navigational structure) × 2(“on” versus “off” music) × 2 (“moving” versus “static” images)between-subjects computer experimental design was used tocarry out the research. Similar types of computer experimentaldesigns with more/less, different/similar web stimuli have beenanalyzed in previous studies (e.g., Eroglu et al., 2001, 2003;Dailey, 2004; Choura and Saber, 2005; Nesset et al., 2011; Changand Wu, 2012). A fictitious store was created for this research(named E-Fashion) to avoid the effects of prior experience witha e-retailer. That virtual shop offered fashion apparel (clothesand accessories) for men and women, in two designs (casualand formal). To standardized products to compare men andwomen, the number of clothes and accessories were the samefor the two genders. To create the content of the virtual shop,we based on a homepage (Schneiderman, 1998; Nielsen, 2000),which incorporates the similar links and web sites as other virtualapparel shops.

In sum, the experimental design consisted on the doublecombination between three types of web stimuli:

(1) Navigation structure stimulus. We used two different webnavigational structure used in this study:

• “Free navigation structure” of the website means thatcostumer can move easily through the website. Forthat, the following tools have been included within thisexperimental condition: “home link,” “location pattern,”“searching window,” “lateral menus in all webpages of thesite”). Consequently, the user is not controlled by marketerwith restrictive navigational bars.• “Hierarchical navigational structure” means that user only

can use the “previous” and “next” navigational bars tomove through the website. In consequence, the previoustools (“home link,” “location pattern,” “searching window,”“lateral menus in all webpages of the site”) have beeneliminated of this experimental condition in order to createmore restrictive navigation to user.

(2) Music stimulus. Two different music web stimuli were usedin this study:

• “On-music” within the webpage. In this case, the musicwas included within the experiment. Music was testedpreviously to analyze which kind of music was preferredby consumers, using music that already existed. The kind

of music included was instrumental and very dynamic, butit was not readily identifiable with any particular singer orspecific group. It was used music of the album Traveler’sguide by Jahzzar, which is licensed under a Attribution-ShareAlike 3.0 International License.• “Off-music.” In this case, the music was eliminated of the

experiment.

(3) Presentation of product stimulus. We used two differentpresentations of products (Martin et al., 2005; Lorenzo et al.,2007):

• “Static images” web design presents the possibility of seeingfrontal images of all products and a window with staticphotos of different models showing several outfits.• “Moving images” web design allows consumers 360◦

visualization of products using gif images according toanimation definition defined by Dahan and Srinivasan(2000) and Sundar and Kalyanaraman (2004), as well awindow with videos in which the models show the fashionapparel of the store (Choura and Saber, 2005; Nesset et al.,2011).

As a result of combination the three webmosphericmanipulations (2 × 2 × 2), eight different websites weredefined:

(1) Hierarchical navigation+ on music+moving images;(2) Hierarchical navigation+ off music+moving images;(3) Hierarchical navigagion+ on music+ static images;(4) Hierarchical navigation+ off music+ static images;(5) Free navigation+ on music+moving images;(6) Free navigation+ off music+moving images;(7) Free navigation+ on music+ static images;(8) Free navigation+ off music+ static images.

In all experimental designs, the content of webpages is thesame (i.e., company description, products description, shoppingcar, security and privacy policy, promotions, fictitious moneyto buy, link to register, new arrivals and sale section, contactand search engine), excepting the changes of stimuli indicatedin each manipulation. From both links previously indicated,according to the each experiment, gifs animated or static images(in the case of “presentation of product” experimental design),and music or not (in the case of “music” experimental design)were included.

Before starting the experiment, a pre-test was conducted to adifferent group to ensure that subjects’ responses give us differentperception by inclusion of the above atmospheric manipulations.

The final sample consisted of 400 participants who weredivided into eight groups (two of them with the navigationalstructure manipulation, two of them with music manipulation,two of them with presentation manipulation). Participants wererandomly assigned to one of these experimental conditions.All members of each group were undergraduate students (18–25 years old, and half of the same were men and the other halfwere women), due to it was a group with enough experienceand positive predisposition to the Internet as to carry outthis experiment in adequate way (Ozok and Wei, 2010). Allgroups were exposed same external environment conditions(place and space) throughout the same day. Besides these aspects,all experiments were checked under same conditions explainedabove: time (50 min, since in the pre-test was demonstrated thatpeople spent on average this time until take a final decision),money (each subject had 200€; of budget, which is an average ofthe total budget that they usually have, according with a previousexploratory analysis) and elements of web site. In order to analyzean equilibrated model, each group was consisted of 50 subjects.

After participants finished the experimental task they werecomplete a final online questionnaire which includes affective,

It is worth noting that that this study was carried out inaccordance with the current ethical and legal recommendationsabout privacy of personal data. Throughout the whole researchwe take into account also the ICC/ESOMAR International Codeon Market and Social Research practices and norms.

A Model of Web Technology Effects onUser Responses. Measurement ofVariablesWe propose an extended model (Figure 1) based on the S-O-Rparadigm (Mehrabian and Russell, 1974), to test the influence ofthree specific atmospheric cues on online shopper responses. Themain objective is to analyze the differences of response betweenthe experimental groups, as well as examining the influence ofmediator variables between the constructs. The analyzed variablesin each construct are showed in Table 1.

Statistical TechniquesRegarding the statistical techniques used in this research, asour major objective is to analyze whether or not there weresignificant differences of behavior between the groups andthe effects of each online atmospheric manipulation cues onfive types of dependents constructs respect to the consumer:Affective, cognition and satisfaction (as internal states), andapproach/avoidance responses and real shopping outcomes(as consumer behavioral responses), a multivariate analysis ofvariance (MANOVA) is used to test this part. Additionally,a multivariate analysis of covariance (MANCOVA) is usedto analyze the mediator effect of involvement, atmosphericresponsiveness, and perceived risk factors between web verbaland non-verbal communication stimuli and user responses.

Previously, as the variable used as dependents and mediatorsare latent variables, it means, non-observable variables measuredthrough scales (see Table 1), we used exploratory factor analysisto describe variability among observed, correlated variables interms of a potentially lower number of unobserved variablescalled factors. Factor analysis searches for such joint variationsin response to unobserved latent variables.

RESULTS

In Tables 2 and 3 are showed the data obtained after factorialanalysis in each construct used, which are necessary to be used inthe multivariate analysis (MANOVA and MANCOVA). The firststep of the analysis is to test the model fit, that is, if it is a good ideato proceed with a factorial analysis for the data, which is showedin Table 2. The next step is to analyze the factors obtained fromthe factorial analysis, which are showed in Table 3.

Specifically, in Table 2 is showed the association levelindicators between analyzed variables which compose thedifferent constructs of our model. For example, “affective”construct shows that its variables are correlated, there is nomulticollinearity since the correlation matrix determinant isgreater than 0.00001, the K-M-O index is greater than 0.8 and

Bartlett’s test of sphericity is highly significant. These indicators,together with the measure of sample adequacy (>0.5), indicategood association level of items on its construct (Iacobucci, 1994;Hair et al., 2006). In the rest of construct (i.e., “cognitive,”“satisfaction,” “behavioral responses,” and “mediator variables”)the results are similar, meaning these results a good associationlevel of items on their constructs. Lower levels are obtainedin the “mediator variables” due to the inclusion of differenttypes of covariates with different meanings (i.e., involvement,atmospheric responsiveness, perceived risk). Nevertheless, theglobal statistics indicators are acceptable (i.e., K-M-O index0.549; p-value < 0.01; measure of sample adequacy withcoefficients between 0.49 and 0.58). It means a good associationlevel between mediator variables.

In Table 3 is showed the factorial analyses for each analyzedconstruct (i.e., “affective,” “cognitive,” “satisfaction” as internalvariables construct; “approach responses” as behavioral responsesconstruct; and “mediator variables or covariates” construct). Eachobtained factor shows the name of items with which is composed.For example, “affective variables construct” is composed by twofactors: “Attitude” and “Emotion.” In this case, each factor iscomposed by three items. The rest of constructs are composedby two factors, excepting “mediator variables” construct which iscomposed by four factors.

In the case of “real shopping outcomes” (within “behavioralresponses” construct) the factorial analysis is not possible dueto the variables are uncorrelated. These variables were obtainedthrough click-through -it has been indicated in Table 1- carriedout by users during their visit within online retail store.Nevertheless, the variables are used in the ANOVA and ANCOVApost analysis (Davino and Romano, 2014).

For each factor has been analyzed the Eigenvalues, thepercentage of explained variance, and specially, the CronbachAlpha index which measures the level of reliability of factor.In all cases, the eigenvalue is greater than 1.000, the level ofexplained variance is higher 0.5 and the Cronbach alpha near1.000 (Cronbach, 1970). It means a good fit of the factorialanalysis (Iacobucci, 1994; Hair et al., 1999).

In sum, as we can observe in Tables 2 and 3, the CronbachAlpha is used as reliability measurement of all analyzedconstructs (Cronbach, 1970). Moreover, the Wilks’ Lambdastatistic was used to test the global significance (Iacobucci, 1994;Hair et al., 1999), using the F-Snedecor statistic and, as acceptedconfidence statistic level, 95% (p-value = 0.05) and 90% (p-value = 0.1), as it is showed in Tables 4 and 5. In consequence,validity and reliability obtained from this factorial analysis showus the suitability of its application for the next multivariateanalysis. Moreover, the content validity is obtained through theapplication of literature in the development of our proposedmodel.

A comparative analysis (MANOVA vs. MANCOVA) isdeveloped in order to compare the effects of web stimuli onuser responses without (MANOVA) and with (MANCOVA) theinclusion of mediator variables, respectively. Each significanceitem (p-value < 0.05 and 0.1) confirm the webmospheric cuespreferred by users. The global contrasts are showed in Table 5(internal states) and Table 6 (behavioral responses).

In order to clarify the specific impact of each stimulus oneach consumer response factor, the individual contrasts areshowed for each web manipulation in Table 6 (i.e., navigationalstructure), Table 7 (i.e., music) and Table 8 (i.e., presentation ofproducts), through ANOVA (univariate analysis of variance) andANCOVAS (univariate analysis of covariance) analysis (Davinoand Romano, 2014).

Effects of Verbal CommunicationStimulus (Utilitarian Dimension) on UserResponses: Navigational StructureThe global contrast MANOVA test (Table 4) shows significantdifferences between groups analyzed regarding the relationshipbetween this verbal web stimulus and all internal states factors (p-value < 0.05). In the ANOVA test (Table 6) we can see the positiveeffect of “free navigation” on user’s internal states. Specifically,the factors like emotion (as affective internal state), believes andlearning/knowledge (as cognitive states), and satisfaction with thedesign (as satisfaction state) are related positively with the “freenavigation” as verbal communication stimulus.

In Table 4, MANCOVA test includes four mediator factorsin which we can see the significance impact of involvement(with apparel and with online shopping) on all of three internalstates. Based on Table 6, the ANCOVA test shows that users whowere exposed to an online shopping environment with the “freenavigation” show more favorable internal responses than those

who were exposed to the “hierarchical navigation” during theirvisit within online retail store (the factors attitude and generalsatisfaction with the visit are not significantly different betweenboth navigational structure including involvement as mediatorfactors).

Regarding atmospheric responsiveness as mediator factor,Table 4 shows the inexistence of significant differences respectto affective and satisfaction internal states (p-value = 0.957 and0.747, respectively). Nevertheless, atmospheric responsivenessinfluence on cognitive states, and we can affirm that users preferfree navigation.

Finally, respect to perceived risk mediator factor, Table 4shows significant influence on affective and cognitive internalstates, whose preference is focus on “free navigation,” but perceiverisk do not influence on satisfaction.

Regarding the effects on behavioral responses, Table 5shows the inexistence of significant differences between analyzedgroups exposed to “hierarchical” versus “free” navigationalstructure on behavioral responses. The impact of internalvariables as mediator factors between this non-verbal stimuliand behavioral responses has not been analyzed. It couldbe the cause of this non-significant effect. The univariatetest of Table 6 does not show significant difference in anyanalyzed factors related to behavioral responses. Moreover,the inclusion of mediator factors (involvement, atmosphericresponsiveness, perceived risk) do not influence on the behavioralresponses.

Effects of Non-verbal CommunicationStimulus (Hedonic Dimension) on UserResponses: Music in the WebsiteTable 4 shows significant differences between this non-verbalstimulus and internal states, specifically respect to cognitionstates. Moreover, analyzing the mean differences between bothtypes of manipulations (“on music” versus “off music”), in theTable 7 we can observe that users who were exposed to anonline shopping environment with the “on music” web designsshow more favorable learning and knowledge of the website andhigher satisfaction with the design than those who were exposedto “off music” conditions within the store. However, there arenot differences between groups respect to affective internal statebased on Table 4 (p-value= 0.932).

On the other hand, we can affirm that that music is anon-verbal stimulus which does not cause differences betweenuser’s behavioral responses, and neither considering mediatingvariables.

Effects of Non-verbal CommunicationStimulus (Hedonic Dimension) on UserResponses: Presentation of ProductThe results obtained in satisfaction construct analyzed (Table 4)show that consumers who were exposed to an online shoppingenvironment with the “moving images” web designs are moresatisfied those who were exposed to the “static images” conditionswithin the store. Moreover, this non-verbal stimulus influencepositively on believes about online apparel purchase (Table 8).

Regarding the effects of non-verbal communication stimuluson behavioral responses (i.e., approach responses and realshopping outcomes), MANOVA test shows significant differences

(Table 5). The ANOVA test (Table 8) indicates that users exposedto “moving images” stimulus show more favorable behaviorintention and opinion about the website that the users exposedto “static images.” Moreover, all real shopping outcomes (i.e.,products bought, time spent during the visit and money spent)are more positives in a “moving images” web design. Specifically,the involvement (with apparel and with online shopping)and perceived risk affect positively on approach responses. Incontrast, only involvement with apparel affect positively on realshopping outcomes. The rest of mediated factors considered havenot significant influence on behavioral responses.

DISCUSSION, LIMITATIONS ANDFUTURE RESEARCH

The S-O-R paradigm can be useful to illustrate the influenceof web atmosphere on consumers. This model indicates thatexternal stimuli (like web atmospheric cues) affect consumers’internal states and, in turn, they have an effect on behavioralresponses, within an online shopping context (Mehrabian andRussell, 1974; Eroglu et al., 2001). In this work, we obtainedthat three dimensions manipulated (i.e., navigational structureas verbal stimulus, and music and presentation of products asnon-verbal stimuli) affect significantly on internal and behavioraluser responses. The results are relevant for retail marketersbecause they must offer attractive online store as unique orcomplementary sale channel to entice people into their shops.

The main contribution of this study, compared to the previousone, is that we have considered many and different variablesand, what it can be more important, the inclusion of somemediator variables that can modify the consumer behavior andcan explain the modification of some established relationships

studied previously. Based on results, and in line with the resultsobtained by Dailey (2004), restrictive navigation act as barriersover web navigation. In this sense, a hierarchical navigation canbe perceived as more restrictive. In addition, consumer’s personalcharacteristics (i.e., involvement, atmospheric responsiveness,and perceived risk) mediate these results. In general, navigationaldesign, as utilitarian or verbal atmospheric cue, has a greater

effect especially on cognitive states (i.e., knowledge, learning andbeliefs on the Internet). It would be necessary and interestingto analyze the impact of internal variables as mediator factorbetween stimulus and behavioral responses (Lorenzo et al., 2007).

Moreover, positive user internal states (specifically,satisfaction) are more favorable with a “music” and “movingimages” web designs and the behavioral responses are more

probable with, specially, “static images” conditions. In addition,users’ personal characteristics also modifies relatively the finalshopping human behavior.

It is necessary to take into account the inclusion of andappropriate music for target market (i.e., more dynamic foryoung people and more paused for old people) in order tooffer users a more attractive virtual shop window. Nevertheless,according our results, the music is a web stimulus not veryrelevant for the sample.

Moreover, the use of verbal communication stimulus, is alsoimportant to improve the user internal states, as can be thesatisfaction toward the use of a website, as Shankar et al. (2003)postulated. However, it is necessary to take into account thenon-verbal stimuli, as the music or the way of presenting theproducts, affect directly on behavioral responses, as satisfaction.In consequence, website designers should include full productscatalog, location information, searching engine and direct accessto home page, in all websites of site, improves the navigationdeveloped by user and, in turn, increase his/her internal statesand shopping responses.

Other recommendation for e-marketers is to analyze theclick-through. They represent real shopping outcomes such astime spent during the visit, products bought, and money spent.Web analytic allows studying the objective shopping outcomesthrough some free web applications like Google Analytics.The combination of subjective (i.e., internal states, approachresponses, mediator variables) and objective data (i.e., click-through) offer e-marketer full information on their customers inorder to analyze their habits and behaviors.

As main limitations, this research has been only focusedon the analysis of relationships between three specific onlineatmospheric cues and internal states/behavioral responses. It is alimitation because; the internal states mediated this relationship,aspect not tested in this research. On the other hand, accordingto literature, these kinds of variables mediate the relationshipbetween webtmospheric cues and consumers’ internal states(Choudhary, 2016). However, in this research their influenceon internal and behavioral responses was studied in order toanalyze the degree of significance in all the constructs. Moreover,the sample was composed of young people who were familiarwith web media (i.e., different web designs, a lot of kinds ofonline stores and experience with digital products, etc.). So,perhaps perceived risk mediator variable is not significance onthe satisfaction construct, due to sample is familiarity with onlineshopping.

Changes between treatments are not entirely ceteris paribus,however, there are many design conditions that change, especiallyin the navigation structure. This is an unavoidable problemin online experiments. So, the obtained conclusions should bestated carefully. This manuscript does not show the mixtureof three manipulations (e.g., free navigation with music anddynamic graphic). It shows that the particular free navigationchosen in this experiment is better than the particular hierarchicalnavigation, and that the particular music played is preferred thanno music, etc.

As future research, it would be interesting to analyze theuser experience toward other manipulations on webmospheric

(e.g., color, different navigational patterns, manipulations aboutmarketing mix elements such as prices, promotions, as suggestedLallemand et al., 2015), and the typology of products bought,main sections visited by users, etc. Moreover, our model couldbe improved using a structural equation modeling in order toanalyze the user’s internal variables [e.g., trust and familiarity,based on TAM (Kim, 2012) as mediator constructs betweenwebmosphere stimuli and behavioral responses (Chen andTeng, 2013)]. Finally, it would be interesting to compare thisresults with other different cultures (McMahan et al., 2014)where the use of the online shopping is different, as well asother characteristics that could affect to the online shopping(e.g., extroversion, familiarity, etc.), as Hofstede et al. (2010)proposed.

Moreover, this research opens a line of research in cognitiveneuroscience. According to Gazzaniga et al. (2002), cognitiveneuroscience is a branch of both psychology and neuroscience,overlapping with disciplines such as physiological psychology,cognitive psychology, and neuropsychology. Therefore, tocomplement the results obtained from a psychologicalperspective about consumer behavior and perceptions, it wouldbe necessary to develop some neuromarketing techniques tounderstand in a more detailed way how the consumers thinkand decide, which involves brain processes that our mindsare not aware of. When experimental designs are combinedwith neuromarketing techniques, they provide insights intoconsumer decisions and actions that are invisible to traditional

market research methodologies (Javor et al., 2013; Gani et al.,2015).

In addition, it would be necessary to study empirically the useof e-commerce by this kind of companies (Solaymani et al., 2012)in order to compare both perspectives, i.e., use of e-commerce bycompanies attending to webmosphere and opinion of consumersbased on webmosphere stimuli received through online store.
