Addictions are neuro-psychiatric disorders with serious repercussions on health. In Mexico, cocaine is the second most commonly used drug after marijuana. However, its use leads to increased addiction, withdrawal syndrome and psychopathology. This study aims to select, using computational learning, the most representative variables among demographic, cognitive and impulsivity

OBJECTIVE Obesity is a complex condition involving biological, psychological, sociocultural and environmental components. Impulsivity seems to be a particularly important factor. Whiteside and Lynam recently proposed dividing impulsivity into four separate dimensions: Urgency, lack of Premeditation, lack of Perseverance and Sensation Seeking (associated with a tendency to exaggerate the impact ...

A number of authors have expressed concern about our lack of knowledge of speedaccuracy strategies in intelligence tests. This study examines whether relations between intelligence-test performance and information-processing measures depend on individual differences in speed-accuracy preferences rather than on capacity limitations and whether the impact of strategic variables changes with incre...

2 Inhibiting impulsive reactions while still defending one's vital resources is paramount to functional self-control and successful development in a social environment. However, this ability of successfully inhibiting, and thus controlling one's impulsivity, often fails, leading to consequences ranging from motor impulsivity to aggressive reactions following provocation. Although inhibitory fai...

BACKGROUND AND AIMS Smartphones allow users to access social networking sites (SNSs) whenever and wherever they want. Such easy availability and accessibility may increase their vulnerability to addiction. Based on the social cognitive theory (SCT), we examined the impacts of outcome expectancies, self-efficacy, and impulsivity on young Chinese smartphone users' addictive tendencies toward SNSs...

Stimulant-dependent individuals (SDI) have abnormal brain metabolism and structural changes involving dopaminergic target areas important for the processing of time. These individuals are also more impulsive and impaired in working memory and attention. The current study tested whether SDI show altered temporal processing in relation to impulsivity or impaired prefrontal cortex functioning. We ...

OBJECTIVE Abnormal responses to social stimuli are seen in people vulnerable to suicidal behavior, indicating possible disruptions in the neural circuitry mediating the interpretation of socioemotional cues. These disruptions have not been empirically related to psychological and cognitive pathways to suicide. In the present study of older suicide attempters, we examined neural responses to emo...

To investigate how time perception may contribute to the symptoms of self-harming Borderline Personality Disorder (BPD) patients, 19 self-harming BPD inpatients and 39 normal controls were given measures of time perception, impulsivity, personality, emotion, and BPD characteristics. A test sensitive to orbitofrontal cortex (OFC) function ("Frontal" Behavior Questionnaire) was also administered,...
