Tiivistelmä
Emotion affects thinking, memory, innovation, and different kinds of behaviours. Response times to emotional visual stimuli reveal human emotion. The purpose of this study was to investigate the interaction among emotion-evocative visual stimuli, response times, response accuracy, and affective experience. In the experiments, 30 participants were asked to perform an emotion-categorization (i.e., negative, neutral, and positive) task while viewing different images. These images varied by dimensions of emotional valence (i.e., negative, neutral, and positive) and arousal (i.e., relaxing, neutral, and arousing). Haptic responses to these stimuli were recorded in terms of response times. Ratings of emotional experiences were collected in terms of valence and arousal.
The results from the statistical analysis showed that the response times for negative images were significantly shorter than both positive stimuli and neutral stimuli. The average numbers of errors were significantly different for different image categories. Participants responded to negative images most accurately, while the neutral image group had the most errors among the three categories. The valence ratings for positive, negative, and neutral images were significantly different from each other. The arousal ratings for the negative images were significantly higher than both positive images and neutral images. The arousal ratings of the correctly responded positive images were higher than the neutral images.
To summarise, three major findings are listed as follows: (1) Emotion-evoking images (including both positive and negative images) elicited faster haptic responses than neutral images. (2) Emotion-evoking images (including both positive and negative images) led to higher accuracy in the emotion-categorization task. (3) Negative high-arousal images elicited the fastest responses, most accurate categorization, and strongest arousal rating for the participants.
