Abstract:

L’impulsivité est une tendance comportementale fréquemment observée dans la population générale mais à des degrés différents. À ce propos, une forte impulsivité augmente les risques de développer un trouble psychiatrique, tel que les différentes formes d’addiction ou des troubles de la personnalité. Pour comprendre l’émergence de ces divers troubles comportementaux, mon projet de thèse s’est porté sur le rôle du contrôle cognitif dans les manifestations de l’impulsivité. Le contrôle cognitif est, en effet, un ensemble de fonctions cognitives nous permettant d’adapter nos comportements à un env

Abstract:

The focus of this thesis is the much debated construct of impulsivity, exploring its meaning, etiology and measurement. The literature review provides a background for the empirical papers, by examining the theoretical underpinnings of impulsivity, from which a plethora of measuring instruments have been generated. The review explores the difficulties associated with measuring a contrast which has little consensus over its components, and highlights studies which have attempted to draw together a common understanding of the construct. The main paper provides a useful exploration of four widely

Abstract:

The research reported in this dissertation supports a conceptualisation of impulsivity as a fundamental trait which is not subsumed by other traits in large scale models of personality, whether of three five or more factors. It argues for this by showing that a measure of impulsivity demonstrates incremental validity over and above the validity of two measures of the Big Five personality traits in the prediction of a variety of behaviours which previous research has linked to individual differences in impulsivity. The research also demonstrates that while impulsivity is a coherent trait it nev

Abstract:

The relationship of swearing in respect to personality, religiosity, and social influences was analyzed in this study. Many assumptions are made about the effects of swear words and the act of swearing can have on an individual. The present study hypothesizes that the use of swears words is dependent on an individual's personality characteristics and that exposure first happens from an external source (mass media outlets) rather than a familiar source (family member). More specifically, extroverted personality types will be more likely to engage in the use of profanity, due to their more impul

Previous research has indicated that maternally expressed Nesp and paternally expressed Grb10, which are expressed in overlapping brain regions, may have a role in mediating risk-taking and/or impulsive behaviours. Impulsivity and risk taking are natural parts of human behaviour; however pathological levels of impulsivity and risk-taking are recognised as clinical traits of many psychiatric disorders.

Individuals in Western societies commonly begin to experiment with alcohol and/or cannabis during their adolescent years. Many experience negative consequences from the use of these substances and a minority develop pathological problems such as abuse and dependence. Previous research has identified myriad individual and environmental variables that precede and predict problematic substance use. Two such risk factors are the personality trait impulsivity and the influence of substance-using peers.

The role of subcortical pathology in altered cognition is increasingly recognised. However, measurement and monitoring of impairments in motivation and behaviour due to subcortical disease is challenging.

Abstract:

Delay discounting involves a hypothetical choice between a smaller-sooner value and a larger-later value. Past research has demonstrated the hypothetical choices made in delay discounting correlate with actual money choices and predict impulsivity with drug use, gambling, and food choices. Though delayed discounting has been studied widely, it is unknown whether impulsivity is a characteristic trait or is influenced by contextual cues. Mindfulness has been demonstrated to improve psychological well-being in various contexts. The present study explored the effect of brief mindfulness exercises

Abstract:

The current study examined the relation of impulsivity and obesity in three neuroimaging studies using MRI techniques to test the hypothesis that deficits in brain regions responsible for inhibitory control are associated with obesity. The first study used voxel-based morphometry (VBM) to explore volumetric differences in lean, overweight, and obese women (N=83) and found that BMI was negatively correlated with grey matter (GM) in the insula, frontal operculum, and inferior frontal gyrus. BMI was positively correlated with white matter (WM) in the fusiform gyrus, parahippocampal gyrus, Rolandi

Abstract:

This thesis examined methods that are used to assess impulsive behaviours in Parkinson’s. The results demonstrated that to obtain the most valid assessment of impulsivity, both people with Parkinson’s and their friends/family should complete questionnaires that have been designed to identify these behaviours in Parkinson’s. In contrast, using behavioural impulsivity tasks is discouraged. The findings also highlight the reward seeking nature of impulsivity in Parkinson’s, informing future treatments designed to reduce these problematic behaviours.
