Sensitivity to punishment and sensitivity to reward and traffic violations

Accident Analysis & Prevention, 2004
The aim of our study consists of contributing information on the relationship between the personality variables derived from Gray's model and the conduct that accompanies the infringement of the road traffic rules. Seven hundred and ninety-two adults of both sexes took part in the study (389 men and 403 women), all of whom had driving licences and ...

Associations between sensitivity to punishment, sensitivity to reward, and gambling

Addictive Behaviors, 2015
The majority of individuals gamble during their lifetime; however only a subset of these individuals develops problematic gambling. Gray's Reinforcement Sensitivity Theory may be relevant to understanding gambling problems. Differences in sensitivity to punishments and rewards can influence an individual's behavior and may be pertinent to the ...

Disordered eating behaviors and reward sensitivity

Journal of Behavior Therapy and Experimental Psychiatry, 2001
This research evaluated the extent to which reward sensitivity demonstrated associations with binge and purge behavior frequency. A verbal operant conditioning task designed to assess conditionability to reward cues was administered to a sample of 34 women who exhibited disordered eating patterns for at least I month prior to study participation ...

Sensitivity to reward and punishment in eating disorders

Psychiatry Research, 2010
The aim of this review was to collate and summarise the self-report data regarding anomalies in sensitivity to reward and punishment in eating disorders (ED) with use of a meta-analysis where possible. Electronic databases were searched to December 2008.

Reward sensitivity in depression: A biobehavioral study.

Journal of Abnormal Psychology, 2007
The approach-withdrawal model posits 2 neural systems of motivation and emotion and hypothesizes that these systems are responsible for individual differences in emotional reactivity, or affective styles. The model also proposes that depression is characterized by a deficit in reward-seeking behavior (i.e., approach motivation) and is associated with a

On the sensitivity analysis of the expected accumulated reward

Performance Evaluation, 2002
Summary: This paper deals with the sensitivity computation of the expected accumulated reward of Markov models. Very often, we are facing the problem of the computation time, especially when the Markov process is stiff. We consider the standard uniformization method for which the global error may be easily bounded.

Sensitivity to reward: implications for overeating and overweight

Appetite, 2004
Sensitivity to reward (STR)-a personality trait firmly rooted in the neurobiology of the mesolimbic dopamine system-has been strongly implicated in the risk for addiction. This construct describes the ability to derive pleasure or reward from natural reinforcers like food, and from pharmacologic rewards like addictive drugs.

Reduced sensitivity to reward in CB1 knockout mice

Psychopharmacology, 2004
Previous studies have demonstrated that the activation and blockade of the cannabinoid type 1 receptor (CB1) leads to an enhancement and decrease of the consumption of food and other orally ingested reinforcers, respectively.To gain further knowledge about the role of CB1 in sucrose/saccharin reinforcing efficacy and intake, we tested CB1 knockout (CB1-

Event-related components of the punishment and reward sensitivity

Clinical Neurophysiology, 2010
The present study investigated the properties of feedback-related negativity (FRN) and P3 component of the event-related potentials (ERPs) and their neural sources localization as neurocognitive correlates of the behavioural inhibition and behavioural activation systems (BIS/BAS). The association between BIS/BAS function and anterior cortical asymmetry

Sensitivity to punishment, sensitivity to reward and sexuality in females

Personality and Individual Differences, 2004
The aim of this work is to study the relationships between several sexual variables (experiences, excitement, anxiety, satisfaction and curiosity in sexual events in the media) and the personality variables proposed by Gray: sensitivity to reward and punishment.
