Executive functions include basic cognitive processes such as attentional control, cognitive inhibition, inhibitory control, working memory, and cognitive flexibility. Higher-order executive functions require the simultaneous use of multiple basic executive functions and include planning and fluid intelligence (e.g., reasoning and problem-solving).
Accordingly, high scores obtained on the BRIEF do not indicate a "disorder of executive function" but rather suggest a higher level of dysfunction in a specific domain of executive functions. Particular attention should also be paid to the Inconsistency scale given that score equal or higher than 7 is indicative of a high degree of ...
Survivors of carbon monoxide poisoning had relatively normal abilities on routine, attentional tasks, but were impaired on high-level functions like attentional switching and control. These lower- and higher-level tasks mirror contention scheduling and the Supervisory Attentional System, respectively.
Executive functioning is a theoretical construct representing a domain of cognitive processes that regulate, control, and manage other cognitive processes. Executive functioning is not a unitary concept; it is a broad description of the set of processes involved in certain areas of cognitive and behavioural control. [1]
The D-KEFS also helps determine how deficits in higher order thinking may impact an individual's functioning. In turn, one's performance can be used to develop coping strategies and rehabilitation programs tailored towards individual's profile of strengths and weaknesses in executive functions.
This ability to represent underlies all other higher executive functions. Shimamura proposed Dynamic Filtering Theory to describe the role of the prefrontal cortex in executive functions. The prefrontal cortex is presumed to act as a high-level gating or filtering mechanism that enhances goal-directed activations and inhibits irrelevant ...
Cognitive flexibility [note 1] is an intrinsic property of a cognitive system often associated with the mental ability to adjust its activity and content, switch between different task rules and corresponding behavioral responses, maintain multiple concepts simultaneously and shift internal attention between them. [1]
Studies have found the frontal lobes to be involved in the executive functions of the brain, which are higher level cognitive processes. [28] This control process is involved in the coordination, planning and organizing of actions towards an individual's goals. It contributes to such things as one's behaviour, language and reasoning.
