Fatigue of Cognitive Control in the Stroop-Task
Working on cognitively demanding tasks for a long time leads to a state of mental fatigue, which involves increased distractability, impaired error monitoring, or more generally an impairment of cognitive control processes. The present study indicates that cognitive control can deteriorate already after about 15 minutes. During a Stroop task, a classical measure of inhibitory control, where a h...
متن کاملthe effect of task cognitive complexity and time limit on the performance of the learners with different proficiency levels in second language writing skill
this study investigated the effects of manipulating the cognitive complexity of tasks along +/- few elements and the time limits on l2 learners writing performance. to conduct the study, 60 iranian efl learners with two levels of proficiency, low and high intermediate, were selected and assigned to three groups based on the time devoted to task completion. the participants performed both a simp...
15 صفحه اولThe impact of alertness on cognitive control.
Many previous studies have found that an increase in phasic or tonic alertness impairs cognitive control, even though overall response times are decreased. This counterintuitive pattern of behavior is still poorly understood. Using a computational model, we show that the behavioral pattern follows directly from two simple and well-supported assumptions: increased alertness reduces the time need...
متن کاملThe neural correlates and functional integration of cognitive control in a Stroop task.
It is well known that performance on a given trial of a cognitive task is affected by the nature of previous trials. For example, conflict effects on interference tasks, such as the Stroop task, are reduced subsequent to high-conflict trials relative to low-conflict trials. This interaction effect between previous and current trial types is called "conflict adaptation" and thought to be due to ...
متن کاملCognitive Control as Alternation of Activation and Suppression in the Stroop Task
Execution of tasks in which information rapidly changes its relevance employs both excitatory and inhibitory top-down control. This assertion is derived from empirical data and computational cognitive modeling of a screen-based Stroop task. Empirical data showing both within-trial (interference and facilitation) and between-trial (negative priming) effects are presented. A computational cogniti...
