  1. In the Eyes of the Beholder: The Application of Eye-tracking Methodology to Sexuality Research Amy D. Lykins Marta Meana University of Nevada, Las Vegas IASR 2005

  2. Introduction to Eye-tracking Methodology • Why we did the study • What is eye-tracking? • Scene perception

  3. How Eye-trackers Work

  4. Purpose of the Current Study • Are erotic images visually processed differently than non-erotic images? • Hypotheses • Condition (erotic, non-erotic) X Scene region (face, body, context) interaction • No main effect for Condition

  5. Methods • Participants • 20 men, 20 women, college-age • Stimuli • erotic and matched non-erotic images • Procedure • 15 second exposure to 5 erotic, 5 non-erotic images

  6. Measures of Interest • Total Number of Fixations • First Gaze Duration (ms) • Total Time (ms)

  7. Results—Total Number of Fixations Male Participants • Interaction significant • Both ♂and ♀ looked at body more times in erotic than non-erotic condition • ♂ looked at face more in non-erotic condition • ♀ looked at context more in non-erotic condition Female Participants

  8. Results—First Gaze Duration Male Participants • Interaction not significant Female Participants

  9. Results—Total Time Male Participants • Interaction significant • Both ♂and ♀ looked at body more in erotic than non-erotic condition • ♂ looked at face more in non-erotic condition • ♀ looked at context more in non-erotic condition Female Participants

  10. Conclusions • Do people attend to erotic pictures differently than non-erotic pictures? YES! • Why not first gaze duration? • Eye-tracking can capture these differences in a quantitative, valid manner

  11. Future Applications • Gender differences • Sexual arousal • Inner cognitions and appraisals • Distractability, memory • Reading of erotic stories • Test on clinical populations
