Spatial and Temporal Parameters of Eye Movements During Viewing of Affective Images

Experimental results about the human eye movement parameters during free viewing of IAPS' images have been presented. For each subject (n = 20), the same positive, negative, and neutral images were presented. Each volunteer had similar scanpath during viewing of images with different valence. Coefficient of correlation (r) between number of tests with detected regions of interest at presentation of negative and positive images was equal to 0.84 (r = 0.80 between the tests with negative and neutral images, r = 0.77 between the tests with positive and neutral images). Similar correlation was revealed for fixation duration. Volunteer groups with dominant focal or scanning trajectories had significant differences in viewing area square, and fixation duration.
