The persistence of aggressive criminal behavior is recurrently observed in offenders despite being previously advised on the negative consequences of their actions. One possible explanation for the continuation of aggressive behaviors could be that they are the consequence of either possible deficits in cognitive flexibility (set-shifting) or in altered feedback processing. Event-related brain ...

OBJECTIVE We compared patients with chronic schizophrenia and normal controls with respect to decision-making ability. Measures were implemented to control for the participants' intelligence levels as well as to ensure to use of a moderate sample size. The goal of this study was to confirm inconsistent results from previous studies which had stemmed from too small of a sample size, highly varia...

BACKGROUND Recognition of objects and their context relies heavily on the integrated functioning of global and local visual processing. In a realistic setting such as work, this processing becomes a sustained activity, implying a consequent interaction with executive functions. MOTIVATION There have been many studies of either global-local attention or executive functions; however it is relat...

Cognitive flexibility hinges on a readiness to direct attention to novel events, and on an ability to change one's mental set to find new solutions for old problems. Human event-related potential (ERP) studies have described a brain 'orienting' response to discrete novel events, marked by a frontally distributed positive potential peaking 300-400 ms post-stimulus (P3a). This brain potential has...
