Evaluating the Induced Emotions on Physiological Response

摘要

Emotions are complex occurrence that is felt at each instant and are entrenched in the underlying state of physiological processes. The cardiac activity reproduces direct quantitative analysis of the induced emotion. The objective of this study is to determine the effect of cardiac response in order to assess the intensity of induced emotion. Ten adult participants are participated in this study. The stimulus to provoke emotion was selected from the International Affective Picture System (LAPS). The positive valence low/high arousal images were selected. The perceived emotion was measured using Self-Assessment Manikin Scale (SAM scale) and physiological response to the stimulus was evaluated using heart rate. The heart rate while viewing positive valence and low arousal pictures was significantly low (p = 0.05) for when compared with non-image appearance period, whereas it was significantly high (p = 0.05) for positive valence and high arousal images. The two-dimensional model of emotion study concludes that the subjective perceived emotion correlates with the induced emotion for the selected categories with arousal playing the most significant role in inducing the changes in cardiac reactions.
