Method Independent variables
1. Relevance and importance assessment. – Is it important for you to change your diet? (Study1)– Is it important for you to change your drinking habits (Study 2)
2. Message about drinking water to loose weight (Study1) / about harmful consequences of overdrinking (Study 2)
– “Dry facts”– Narrative.
• Modality – Written text– Audio recording

MethodDependent variables
• Persuasion– How convincing the message was? – Do you believe,
• drinking water is helpful for loosing weight? (Study1)• drinking too much is harmful (Study 2)
– Do you intend to • start drinking more pure water? (Study 1)• moderate your drinking (Study 2)
• Transportation – (A level of story absorption) (Study 2)

Hypotheses
• Participants who are highly interested in the topic will be more convinced by the “factual” message than by the “narratives” and vice versa.
• “Narratives” will be more convinced in an “audio” format.

Conclusions and recommendations
• If you can use two different channels…– Do audio recording for narratives and write
facts.
• If you know your audience…– For highly involved people
• Use text
– For low involved people (to draw attention)• Use audio

Conclusions and recommendations
• If you can vary everything (audience, channel and message type)…– Use audio narratives for “low involved”
people.– Use written facts for “highly involved” people.
