Individual Features of Viewing Emotionally Significant Images

摘要

Experimental data on the individual features of eye movements on viewing affective images from the IAPS database are presented. The results provide evidence that the viewing trajectory in each subject (n = 20) persisted on presentation of images with different emotional coloration. The whole cohort of subjects showed a significant correlation between the numbers of tests in which areas of interest were detected, in three combinations: between negative and positive images, between negative and neutral, and between positive and neutral (r = 0.84, 0.78, and 0.77, respectively). Analogous correlations were seen for the duration of gaze fixations (r = 0.90, 0.82, and 0.90). The number of fixation points in areas of interest, the size of the areas examined, and the duration of fixations were found to differ significantly between two groups of subjects (with dominance of focal or scanning gaze trajectories). The potential for using emotionally significant images for assessing the dominant type of visual attention in terms of eye movement parameters in individual humans is discussed.
