Preliminary conclusions
• Epistemics effects involvement, not distance
• Valence effects distance, not involvement
• Relevance and Aesthetics are important factors as well!
Task performance
Mean
Positive valence 82
Negative valence 75
F(1, 128) = 4.48, p < .036
Preliminary conclusion:
Valence effects task performance,
Epistemics does not
Experiment 2• Are the Engagement and Interaction
process dependent on each other?
• Aesthetics: ugly versus beautiful
• Affordances: aids versus obstacles
Manipulations(pilot tests conduced soon)
Measures
• Involvement and distance
• Intentions to use and Intentions not to use
• Satisfaction
• Task performance
