Chemical neuromodulation of cognitive control avoidance

Chemical neuromodulation of cognitive control avoidance

Why do we so often fail to exert cognitive control, even though we are in principle able to do so? In this review, we begin to address this question by considering the contribution of the major ascending neuromodulators that are often implicated in cognitive control and motivation, in particular dopamine, noradrenaline and serotonin. Accumulating evidence indicates that cognitive control is sub...

A theory of cognitive control, aging cognition, and neuromodulation.

A theory is described which links cognitive changes observed in normal aging to an underlying decline in the function of the dopamine (DA) system projection to prefrontal cortex (PFC). The theory postulates that this neural mechanism is integral to the representation, maintenance and updating of context information, and as such impacts cognitive control across a wide range of cognitive domains,...

Enhancement of cognitive control by approach and avoidance motivational states.

Affective variables have been shown to impact working memory and cognitive control. Theoretical arguments suggest that the functional impact of emotion on cognition might be mediated through shifting action dispositions related to changes in motivational orientation. The current study examined the effects of positive and negative affect on performance via direct manipulation of motivational sta...

Approach, Avoidance, and Inhibition: Personality Traits Predict Cognitive Control Abilities.

The extent to which approach and avoidance personality trait sensitivities are associated with specific cognitive control abilities as well as with verbal and nonverbal domains remains unclear. In the current study, we investigated whether approach and avoidance trait sensitivities predict performance on verbal and nonverbal versions of the Stroop task, which taps the specific cognitive control...
