BACKGROUND High impulsivity and attentional bias are common in cocaine-dependent patients and predict poor treatment outcomes. The pharmacological agent modafinil is studied for its cognitive-enhancing capacities and may therefore improve clinical outcomes in crack-cocaine dependent patients. In this study, we investigated first whether pre-treatment impulsivity and attentional bias predict tre...

Objective. Executive function and attention are highly complex cognitive constructs that typically reveal evidence of impairment in people with schizophrenia. Studies in this area have traditionally utilised abstract tests of cognitive function and the importance of using more ecologically valid tests has not been extensively recognised. In addition, there has been little previous examination o...

Cognitive control is essential to flexible, goal-directed behavior under uncertainty, yet its underlying mechanisms are not clearly understood. Because attentional functions are known to allocate mental resources and prioritize the information to be processed, we propose that the attentional functions of alerting, orienting, and executive control and the interactions among them contribute to co...

boxing is one of the organized high-contact sports that requires purposefulpunches to the head and body of the opponent in both amateur and professionallevels, so traumatic head injury in boxers isn’t impossible. in this type of injury,though intact cognitive functions, it is possible that total cognitive beneficiarybecome impaired as a result of distractibility, imperfect concentration, andaft...

OBJECTIVE The 22q11.2 deletion syndrome (DiGeorge/velocardiofacial syndrome) is associated with attentional problems and executive dysfunction, and is one of the highest known risk factors for schizophrenia. These behavioral manifestations of 22q11.2 deletion syndrome could result from haploinsufficiency of the catechol O-methyltransferase (COMT) gene, located within the 22q11 region. The goal ...

Classical theories of automaticity assume that automatic processes elicited by unconscious stimuli are autonomous and independent of higher-level cognitive influences. In contrast to these classical conceptions, we argue that automatic processing depends on attentional amplification of task-congruent processing pathways and propose an attentional sensitization model of unconscious visual proces...

Findings on neuropsychological associates of the negative syndrome of schizophrenia have been inconsistent. The "deficit syndrome," a reconceptualization of the negative syndrome, was developed in part to address this inconsistency. The purpose of this study was (1) to replicate previous findings relating the deficit syndrome to impairment of certain kinds of attentional abilities, and (2) to c...

The article is a narrative review of the theoretical standing and empirical evidence for the cognitive behavioural model of medically unexplained symptoms (MUS) in general and for chronic fatigue syndrome (CFS) and irritable bowel syndrome (IBS) in particular. A literature search of Medline and Psychinfo from 1966 to the present day was conducted using MUS and related terms as search terms. All...
