Given the complexity of controlling impulsive behaviour in the context of goal maintenance and risk avoidance, there is considerable interest in determining what factors give rise to, and regulate, impulsive behaviour. A recent meta-analysis by Sharma and colleagues (Sharma, Markon, & Clark, 2013) demonstrated several personality-based factors associated with self-report measures of impulsivity: Extraversion/positive emotionality, neuroticism/negative emotionality and disinhibition, and a further set of cognitive ‘behavioural impulsivity’ factors: Inattention, inhibition, impulsive decision-making and shifting. Of note, the relationship between self-reported and experimental measures of impulsivity in the study of Sharma et al. (2013) were lower than expected, possibly indicating that the traditional laboratory measures of impulsivity rely on measuring response inhibition in isolation, ignoring the interplay between executive functions, which is required to emulate impulsive behaviour outside the experimental context (Miyake et al., 2000). Importantly, despite a low relationship between self-reported and laboratory impulsivity tasks, inhibitory ability is featured by Sharma and colleagues (2013) as a factor in both experimental tasks and self-reports and is the focus of the current study.
