The relationship between trait-impulsivity and smoking expectancies on smoking progression in undergraduate college students was examined over a 48-hour period of smoking abstinence. Participants were forty-nine college-aged dependent cigarette smokers who completed measures designed to assess impulsivity, nicotine dependence, and smoking expectancies. Using a series of multilevel models, impul...

OBJECTIVE Executive function, impulsivity, and intelligence are correlated markers of cognitive resource that predict health-related behaviours. It is unknown whether executive function and impulsivity are unique predictors of these behaviours after accounting for intelligence. METHODS Data from 6069 participants from the Avon Longitudinal Study of Parents and Children were analysed to invest...

In contrast to the traditional viewpoint of psychopathology, which compulsivity [a repetitive ritualistic behavior which persists albeit its inappropriateness to the given situation and often result in undesirable consequences] and impulsivity [which encompasses actions that are insufficiently conceived, prematurely expressed, excessively risky or inappropriate to the situation, and that often ...

BACKGROUND Impulsivity is a multidimensional construct which has been associated with dopaminergic neurotransmission. Nonetheless, until this moment, few studies addressed the relationship between different types of impulsivity and the single nucleotide polymorphism caused by a substitution of valine (val) with methionine (met) in the 158 codon of the Catechol-o-Methyltransferase gene (COMT-val...

Impulsivity is widely related to socially problematic behaviors and psychiatric illness. Previous studies have investigated the relationship between response inhibition and impulsivity. However, no study has intensively examined how impulsivity correlates with automatic sensory processing before the drive for response inhibition to sensory inputs. Sensory gating (SG) is an automatic inhibitory ...

BACKGROUND Traditionally, impulsivity has been regarded as a stable trait. However, a series of longitudinal and behavioural laboratory studies has found that impulsivity can fluctuate within individuals, suggesting that it has a state as well as a trait manifestation. Whilst existing impulsivity questionnaires tap the former, there is no self-report instrument to assess recent fluctuations in ...

A major problem in the research considering impulsivity is the lack of mutual understanding on how to measure and define impulsivity. Our study examined the relationship between self-reported impulsivity, behavioral excitatory and inhibitory processes and time perception. Impulsivity--fast, premature, thoughtless or disinhibited behavior--was assessed in 58 normal, healthy participants (30 men,...
