Towards understanding the effects of individual gamification elements on intrinsic motivation and performance
TL;DR: It is suggested that in this particular study context, points, levels and leaderboards functioned as extrinsic incentives, effective only for promoting performance quantity.
Journal ArticleDOI

Iris-Katharina Penner,C. Raselli,Markus Stöcklin,Klaus Opwis,Ludwig Kappos,Pasquale Calabrese +5 more
TL;DR: The FSMC is a new scale that has undergone validation based on a large sample of patients and that provides differential quantification and graduation of cognitive and motor fatigue.
Proceedings ArticleDOI
Do points, levels and leaderboards harm intrinsic motivation?: an empirical analysis of common gamification elements
TL;DR: It is suggested that points, levels and leaderboards by themselves neither make nor break users' intrinsic motivation in non-game contexts, and it is assumed that they act as progress indicators, guiding and enhancing user performance.
Journal ArticleDOI
Is beautiful really usable? Toward understanding the relation between usability, aesthetics, and affect in HCI
TL;DR: The results indicate that the user's affective experience with the usability of the shop might serve as a mediator variable within the aesthetics-usability relation: the frustration of poor usability lowers ratings on perceived aesthetics.
Journal ArticleDOI
Visual complexity of websites: Effects on users' experience, physiology, performance, and memory
TL;DR: It is demonstrated that visual complexity of websites has multiple effects on human cognition and emotion, including experienced pleasure and arousal, facial expression, autonomic nervous system activation, task performance, and memory, and it should thus be considered an important factor in website design.
