Investigating the relationship between reward sensitivity, impulsivity, and food addiction: A systematic review.

Objective: The aim of the current research was to identify the extent to which reward sensitivity and impulsivity were related to food addiction.

Method: Forty-five studies, published from 2009 to June 2019, investigating reward sensitivity and/or impulsivity with food addiction as measured by the Yale Food Addiction Scale were reviewed.

Results: Reward sensitivity, as measured by the Sensitivity to Reward (SR) scale, was positively associated with food addiction in two studies, but failed to yield consistent results in other studies when measured with the Behavioral Inhibition/Behavioral Activation Scales.

Integrating the context-appropriate balanced attention model and reinforcement sensitivity theory: Towards a domain-general personality process model.

Over the last 40 years or more the personality literature has been dominated by trait models based on the Big Five (B5). Trait-based models describe personality at the between-person level but cannot explain the within-person mental mechanisms responsible for personality. Nor can they adequately account for variations in emotion and behavior experienced by individuals across different situations and over time.

Left hemispheric lateral preference and high neuroticism predict disinhibition in two go/no-go experiments.

Although disinhibition is widely implicated in impulse-control-related psychopathologies, debate remains regarding the underlying approach and avoidance processes of this construct. In two studies, we simultaneously tested three competing models in which varying levels of extraversion, neuroticism, and hemispheric lateral preference are associated with disinhibition. In both studies (Study 1, N = 92; Study 2, N = 124), undergraduate students were randomly allocated to one of two versions of the go/no-go task: one where participants were primed through reward to make more "go" responses and another where no such priming occurred.

Workplace mavericks: how personality and risk-taking propensity predicts maverickism.

We examine the relationship between lateral preference, the Five-Factor Model of personality, risk-taking propensity, and maverickism. We take an original approach by narrowing our research focus to only functional aspects of maverickism. Results with 458 full-time workers identify lateral preference as a moderator of the neuroticism-maverickism relationship.
