Pupil Size Variation Related to Oral Report of Affective Pictures

AbstractThe goal of the experiment was to establish pupil size variations while viewing and reporting 48 affective (IAPS) pictur es. The experiment consisted of 44 students. Pictures appeared on the screen for 20 secs in random order. After reporting the SAM (Self-Assessment Manikin), the participants orally reported on the pictures. In the phase of picture viewing, the unpleasant pictures revealed larger pupillary responses than neutral and pleasant pictures (p<.001). The mean pupil size was at its great est also during the reporting of unpleasant pictures (p< .001). Results indicated that the differences in pupil size variations endure from the viewing phase to the reporting phase of pictures

Heart Rate Variability (HRV) reflecting from oral reports of negative experience

AbstractWe measured HRV in 25 females while they were evaluating and reporting 48 affective pictures, which appeared on the screen for 20s in random order. After reporting the SAM, the participant orally reported to the experimenter, what she saw, what had happened, and what was going to happen in the picture. Spectral analysis was performed on the data using the fast Fourier transform. Preliminary results indicate that during negative pictures, LF/HF activity is significantly higher in the picture phase than in the speech phase
