UNASSIGNED: Recent studies have shown that the neuropeptide @entity398 is involved in the regulation of several complex @entity1 social behaviours. There is, however, little research on the effect of @entity398 on basic mechanisms underlying @entity1 sociality, such as the perception of biological motion. In the present study, we investigated the effect of @entity398 on biological motion perception in @entity235 ( @entity235 ), a species adapted to the @entity1 social environment and thus widely used to model many aspects of @entity1 social behaviour. In a within-subjects design, @entity235 (N  =  39), after having received either @entity398 or placebo treatment, were presented with 2D projection of a moving point-light @entity1 figure and the inverted and scrambled version of the same movie. Heart rate (HR) and heart rate variability (HRV) were measured as physiological responses, and behavioural response was evaluated by observing @entity235 ' looking time. Subjects were also rated on the personality traits of @entity663 and Agreeableness by their owners. As expected, placebo-pretreated (control) @entity235 showed a spontaneous preference for the biological motion pattern; however, there was no such preference after @entity398 pretreatment. Furthermore, following the @entity398 pretreatment female subjects looked more at the moving point-light figure than males. The individual variations along the dimensions of Agreeableness and @entity663 also modulated @entity235 ' behaviour. Furthermore, HR and HRV measures were affected by @entity398 treatment and in turn played a role in subjects' looking behaviour. We discuss how these findings contribute to our understanding of the neurohormonal regulatory mechanisms of @entity1 (and non- @entity1 ) social skills.
