Appraisal influences on somatovisceral responses and motivation

Published in Psychophysiology. 2006, vol. 43, p. S21
Abstract Several appraisal theorists postulate that appraisal outcomes produce specific somatovisceral response patterns. In addition, appraisals are supposed to influence motivational states like approach and withdrawal tendencies. In the context of a task on sensorimotor coordination, participants were presented with pictures displaying unpleasant, neutral, and pleasant stimuli (intrinsic pleasantness manipulation). Itwas hypothesized that participants desired to increase the size of pleasant and decrease the size of unpleasant images (goal conducivenessmanipulation). The performance of arm movements (flexion vs. extension) yielded either an increase or a decrease of picture size. Results for heart rate and facial electromyogram show differential efferent effects of the respective appraisal outcomes. Importantly, the idea of arm flexion and extension as evolutionarily precoded indicators of approach and withdrawal tendencies is strongly questioned by our results.
