Pupillary Reactions to Sexual, Aggressive, and Other Stimuli as a Function of Personality

Summary This study investigated how well three personality measures, The Dream Incident Technique, the Edwards Personal Preference Schedule, and the Repression-Sensitization Scale, could predict pupillary dilation to a set of experimental stimuli. The stimuli were brief video sequences portraying themes of sex, aggression, achievement, affiliation, nurturance, dominance, and order. The Dream Incident Technique was most predictive of pupillary dilation to these scenes. The Edwards Personal Preference Schedule correlated only with self reports of stimulation. The R-S Scale was unrelated to either pupillary dilation or self report of stimulation.
