Binocular Rivalry and Schizotypal personality traits in non-clinical individuals.

Abstract

Event Abstract Back to Event Binocular Rivalry and Schizotypal personality traits in non-clinical individuals. Anna Antinori1*, Luke D. Smillie1, Phillip Smith1 and Olivia Carter1 1 The University of Melbourne, School of Psychological Sciences, Australia Binocular Rivalry occurs when different images are presented simultaneously to each eye. The perceptual competition of the two images results in the observer perceiving an alternation between the two distinct images. However, people also report periods of a "mixed" - with the images scrambled or fused - percept either for short or long period. Even if the “mix” percept is reported in studies of binocular rivalry, little is known about it. The mix percept appears to be longer and more frequent in early childhood and its existence proves that binocular rivalry is more than mere eye competitions. Clinical conditions show an atypical rate of perceptual alternation: bipolar disorder has a slower rate and anxious personality a faster one. Purpose: To show that mix percept might be correlated to clinical or subclinical conditions in particular with positive symptoms of psychosis characterized by hallucinations and perceptual aberration. Methods: Participants (n=78) performed a perceptual rivalry visual task viewing simultaneously and in each eye respectively a vertical gratings and a horizontal one. Participants reported which of the two images were dominant or if they perceive a mix percept. To measure several dimensions of schizotypy the Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE) was administered. Results: A Spearman’s rho correlation coefficient was computed to assess the relationship between the mix percept during binocular rivalry and the score obtained on the “Unusual Experiences” O-LIFE subscale . There was a positive significant correlation between the two variables r(78)= . 23, p =.045. Conclusion: The result of our research suggests that subjects with longer “mix” percept during binocular rivalry might be more at risk to develop psychological disorders. This could be useful in the clinical field to help early diagnosis of psychopathologies.
