This week our own Dr Chris Jackson will tell us about his recent work on laterality and personality. Chris will give this presentation on Friday the 1st of April at 3pm, room 302 of the McElwain Building. Hope to see you there.

Inhibited to Disinhibited
The moderating effect of Aural preference on Neuroticism in the prediction of Disinhibition, Psychopathy, Work performance, Alcohol, Drug use and conflict resolution in the 'lolly shop'
Disinhibition is usually defined as a combination of high Extraversion and high Neuroticism. The hypothesis that Neuroticism interacts with Aural preference (preferred-ear for listening) in the prediction of Disinhibition is tested. The importance of Aural preference rests on the assumption that it is a readily available proxy measure of contra-hemispheric preference such that a left Aural preference is indicative of right hemispheric preference and vice versa. Since the left hemisphere acts to initiate approach behaviour, the hypothesis investigates a model in which preference for the left hemisphere, together with high Neuroticism, provides an alternative conceptualization of Disinhibition. Five studies provide replicated evidence in favour of the hypothesis in which disinhibited behaviours in everyday life are measured in different ways. Study 1 shows that a newly developed scale of Disinhibition can be predicted from high Neuroticism in interaction with right Aural preference; Study 2 shows that the interaction predicts Disinhibition as a major component of psychopathy. Study 3 shows that the interaction predicts disinhibited telesales work performance. Study 4 shows that the interaction predicts alcohol and drug use. Study 5 is a lab study which partly mirrors conflicts that need to be resolved in a lolly shop. Here the neuroticism x aural preference interaction predicts speed of conflict resolution.
