Context-dependent modulation of cognitive control involves different temporal profiles of fronto-parietal activity Ghent University KU Leuven
To efficiently deal with quickly changing task demands, we often need to organize our behaviour on different time scales. For example, to ignore irrelevant and select relevant information, cognitive control might be applied in reactive (short time scale) or proactive (long time scale) mode. These two control modes play a pivotal role in cognitive-neuroscientific theorizing but the temporal dissociation of the underlying neural mechanisms is not ...
The Longitudinal Effect of Bilingual Immersion Schooling on Cognitive Control and Intelligence Vrije Universiteit Brussel Ghent University
Throughout the past century, the effects of bilingualism on general cognition have been extensively explored. Studies evolved from a negative to a more positive perspective, but longitudinal assessments of effects of bilingualism are scarce. This study investigated the long-term effect of becoming a bilingual on the development of general intelligence and cognitive control. We followed 27 five-year-old children initiating bilingual kindergarten ...
Wearing a bike helmet leads to less cognitive control, revealed by lower frontal midline theta power and risk indifference Ghent University
A recent study claims that participants wearing a bike helmet behave riskier in a computer-based risk task compared to control participants without a bike helmet. We hypothesized that wearing a bike helmet reduces cognitive control over risky behavior. To test our hypothesis, we recorded participants' EEG brain responses while they played a risk game developed in our laboratory. Previously, we found that, in this risk game, anxious participants ...
Grounding cognitive control in associative learning Vrije Universiteit Brussel Ghent University
Cognitive control covers a broad range of cognitive functions, but its research and theories typically remain tied to a single domain. Here we outline and review an associative learning perspective on cognitive control in which control emerges from associative networks containing perceptual, motor, and goal representations. Our review identifies 3 trending research themes that are shared between the domains of conflict adaptation, task ...
Causal evidence for learning-dependent frontal lobe contributions to cognitive control Ghent University
The lateral prefrontal cortex (LPFC) plays a central role in the prioritization of sensory input based on task relevance. Such top-down control of perception is of fundamental importance in goal-directed behavior, but can also be costly when deployed excessively, necessitating a mechanism that regulates control engagement to align it with changing environmental demands. We have recently introduced the "flexible control model" (FCM), which ...
