Short Communication Closing one’s eyes to reality: Evidence for a dopaminergic basis of Psychoticism from spontaneous eye blink rates

چکیده
We tested the idea that Psychoticism, a major personality dimension, is rooted in individual differences in dopamine functioning. To this end, we related the spontaneous eye blink rate (EBR), a marker of striatal dopaminergic activity, to scores in the Eysenck Personality Questionnaire Revised Short Scale (EPQ-RSS) in adult healthy subjects. The level of Psychoticism was indeed predicted by EBR: people with higher scores on the Psychoticism scale showed higher EBRs. No relationship was found between EBR and other major personality dimensions, such as Neuroticism, Extraversion, or social conformity. These findings point to a central role of dopamine in Psychoticism. 2008 Elsevier Ltd. All rights reserved.

متن کاملA Fast, Robust, Automatic Blink Detector
Introduction “Blink” is defined as closing and opening of the eyes in a small duration of time. In this study, we aimed to introduce a fast, robust, vision-based approach for blink detection. Materials and Methods This approach consists of two steps. In the first step, the subject’s face is localized every second and with the first blink, the system detects the eye’s location and creates an ope...
متن کاملExperimental Study on the Effect of monitor height on Eye Indices Influencing Eye Discomfort among VDT Workers
Introduction: Nowadays, excessive computer use in the workplace has raised concerns about the health status of VDT workers, particularly complaints about eye discomforts. Due to the importance of the eyelids and eye closure parameters on eye health during computer works and the direct effect of monitor height on these parameters, this study was aimed to examine the effect of different monitor h...
متن کاملCharacterizing the spontaneous blink generator: an animal model.
Although spontaneous blinking is one of the most frequent human movements, little is known about its neural basis. We developed a rat model of spontaneous blinking to identify and better characterize the spontaneous blink generator. We monitored spontaneous blinking for 55 min periods in normal conditions and after the induction of mild dry eye or dopaminergic drug challenges. The normal sponta...
متن کاملSpontaneous eye blink rate predicts learning from negative, but not positive, outcomes.
A large body of research shows that striatal dopamine critically affects the extent to which we learn from the positive and negative outcomes of our decisions. In this study, we examined the relationship between reinforcement learning and spontaneous eye blink rate (sEBR), a cheap, non-invasive, and easy to obtain marker of striatal dopaminergic activity. Based on previous findings from pharmac...
