Abstract:
The possibility of evaluating the emotional impressions of pictures was examined using the cross power spectrum density (CPSD) of small eye movements. Pictures were employed as a set of normative emotional stimuli and were presented to 7 male subjects in order to evoke emotional impressions. The eye movements resulting from each stimulus were measured using a video based eye tracker while the viewer's subjective impression for each picture was rated. The stimuli were then grouped as ``Pleasant'' or ``Unpleasant''. In comparing the CPSDs of eye movements between two groups, the powers of the CPSDs for the ``Unpleasant'' group were significantly higher, at 3.75-7.5Hz during the 400-1033.3ms after stimulus onset. This result confirms that eye movements reflect viewer's emotional impression.
