Anxiety and Stress Slide 2 Anxiety Apprehension Anticipatory - Anxious Apprehension Future-oriented mood state in which one is ready or prepared to attempt to cope with upcoming negative events. State of undirected arousal following perception of threat Slide 3 Anxiety: It is an emotion? Specific event Physiological arousal Subjective feelings Behavior Cognitive Appraisals How are fear and anxiety different? Slide 4 FearAnxiety Cognitive Appraisals Something bad now, very soon Something bad in the future Cognitive Appraisals Controllable, Novel, Unexpected, Can Cope, Close in Time. Uncontrollable, Unexpected, Cant Cope, Far In Time PhysiologyWeak limbs, heart races, dry mouth Tension BehaviorFlee, desire to escape, can cope successfully! Limited responses, cant cope, dont know how to cope Subjective Feelings Unpleasant, highly arousing Unpleasant highly arousing, helplessness TimingOccurs post-stimulusOccurs pre-stimulus Slide 5 Attention: Fear vs. Anxiety Fear: Focuses our attention to threatening stimuli Post-Stimulus Anxiety: Focuses our attention to threatening stimuli Maintains our attention to threatening stimuli, especially highly fearful stimuli Pre-stimulus Slide 6 Genetic Structure: Anxiety vs. Fear Fear Animal Phobia Situational Phobia Anxiety Social Phobia Panic & Agor. PTSDGADDepression (Hettema et al., 2005 ) Slide 7 Brain Activation: Anxiety versus Fear (Davis & colleagues, 1998, 2003) Slide 8 When fear becomes anxiety Anxiety = unresolved fear When the coping attempts for fear fail Often in uncontrollable situation Slide 9 Is Anxiety a Basic Emotion? A few say yes! Grays BIS More say no! Ekman, Izard, and Williams James! No universal facial expressions. But, universal appraisals.

Slide 11 With PTSD Without PTSD With Previous PTSD Physiological Measures Slide 12 Slide 13 Subjective Feelings Slide 14 Slide 15 Physiological Arousal Fear Response Anxiety Response Combo! Slide 16 What is the purpose of anxiety? Automatic Processing: To detect/anticipate potential threats in our environment Maintains our attention toward threatening stimuli (less likely to disengage) To be aware of objects we consider most dangerous (e.g., phobias) Slide 17 Automatic Processing and Threat Detection Automatic, non-conscious mental activity gives us early warning system for detecting threat Implication: You can know and not know something at the same time--not know it consciously, know it unconsciously Basic technique: Backward masking Slide 18 1. Present picture of threatening stimulus very quickly (30 milliseconds) 2. Immediately after threat photo is shown, show a non-threatening picture. The second picture is a mask, blocks first picture from consciousness. 3. Reaction to first (masked) picture indicates unconscious processing Backward Masking Slide 19 Automatic Processing of Fearful Stimuli: Results of Masked Stimuli Only Slide 20 Anxiety Maintains Attention / Harder to Disengage Dot Probe Detection Paradigm Present two words above a cross. Words were threatening or neutral. Position of words varied. A dot replaces one of two words. Sometimes dot replaces threatening word. Sometimes dot replaces neutral word. Told to read top word aloud. Press button when see the dot. Measure reaction time to locating dot.

Guthrie Yarwood44 (Fabes & Eisenberg, 1997) Slide 45 Primary Appraisal: perceive a threat to oneself Secondary Appraisal: assess whether one has the resources to cope with the threat Coping: process of executing a response to the stressor. (Lazarus, 1966; Lazarus & Folkman, 1984) 45 2015 M. Guthrie Yarwood Slide 46 Primary Appraisal: Not passing my qualifying exams Secondary Appraisal: Can I handle this? I can make a study schedule! Coping: Study everyday from 8-5 and take off on Wednesday (Lazarus, 1966; Lazarus & Folkman, 1984) 46 2015 M. Guthrie Yarwood Evidence for Lazarus Slide 47 Think about your first exam. 2015 M.
