Studies to see if the valence, gender and the cue of the stimulus affect eye movements (fixations, saccades, their quantity and duration) and the change in the diameter of the vibe are not large. There are several studies that have proven that observing emotional stimuli records and saccades is recorded more than observing neutral stimuli and assessing the influence of sex on eye movement results in conflicting results. To assess the change in the diameter of the pupil, it was found that when assessing the influence of stimuli on the diameter of the vomit is not so trivial. Therefore, we conducted a study aimed at assessing attention to emotional stimuli using the registration of sight parameters. The study included 6 women and 6 men, age 24.7 ± 2.0 years. The stimuli were selected from the NAPS and IAPS databases. Eye movement recording was used to measure changes of fixations, saccades and pupil diameter. The subjects completed questionnaires (TAS-20, GAD-7, GDS, GERAS) aiming to evaluate the relationship between well-being and personality traits to the eye movement parameters obtained. All data collected were evaluated based on the sex of the subjects (men vs. women), stimulus category (erotic vs. unpleasant vs. neutral). The results of the study revealed that more fixations and saccades were performed during the observation of neutral stimuli, and the duration of the saccades was longer than when observing erotic and unpleasant stimuli. When observing erotic stimuli, fixations were longer than observing neutral and unpleasant stimuli. The more unpleasant and more arousing the unpleasant stimuli were, the less fixations the subjects performed by observing them. Regardless of the category of stimulus, males performed more fixations and saccades, but female fixations were longer. The diameter of the pupil increased significantly after about 300 ms after the appearance of the hint, but the change in diameter did not depend on the category of the hint. |
