Scherer's Component Process Model provides a theoretical framework for research on the production mechanism of emotion and facial emotional expression. The model predicts that appraisal results drive facial expressions, which unfold sequentially and cumulatively over time. In two experiments, we examined facial muscle activity changes (via facial electromyography recordings over the corrugator,...

Neuroimaging research has demonstrated that the posterior cingulate cortex (PCC) is functionally compromised in individuals diagnosed with amnestic mild cognitive impairment (MCI), a major risk factor for the development of Alzheimer's disease (AD). In functional MRI studies with healthy participants, this same region is active during self-appraisal (requiring retrieval of semantic knowledge ab...

Appraisal theories in psychology investigate the emotion elicitation process though the cognitive appraisal of stimuli. They offer predictions regarding resulting facial expressions as well as action tendencies based on the way an event is appraised. We used these predictions to achieve nonverbal expressivity synthesis of Embodied Conversational Agents. Two approaches were adopted, a stand-alon...

Beaudry and Pinsonneault (2005) IT related coping behaviors System users choose different adaptation strategies based on a combination of primary appraisal (i.e., a user’s assessment of the expected consequences of an IT event) and secondary appraisal (i.e., a user’s assessment of his/her control over the situation). Users will perform different actions in response to a combination of cognitive...

A human subject experiment was conducted to investigate caffeine’s effect on appraisal and performance of a mental serial subtraction task. Serial subtraction performance data was collected from three treatment groups: placebo, 200, and 400 mg caffeine. The data were analyzed by caffeine treatment group and how subjects appraised the task (as challenging or threatening). A cognitive model of th...

How does mere social presence affect cognitive processes? The extant literature has focused on the impact of social presence on cognitive resources. The present study extends this work by focusing on the positivity of cognitive appraisal. Building on recent findings it was predicted that the traits neuroticism and impression management will differentially moderate the effect, such that neurotic...

Cognitive appraisal before competition includes self-efficacy, traditionally defined as motivation and the perceived ability to perform well; presumably, both dimensions would affect the biological response to a contest. We aimed to analyze the role of self-efficacy in the psychobiological response to a competition in women. Forty university students were confronted in pairs on a laboratory com...

The cognitive appraisal of an event is crucial for the elicitation and differentiation of emotions. Similar appraisals will result in similar emotions, but the appraisal of one and the same event may depend on culturally defined concepts. Appraising an event as unjust, for instance, and its agent as responsible are cognitive determinants for anger. Justice, however, is defined through cultural ...
