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]
Psychological tests such as the WCST, administered alone, cannot be used to measure the effects of a frontal lobe injury, or the aspects of cognitive function it may affect, such as working memory; a variety of tests must be used. [17] [30] [31] A participant may be good at one task but show dysfunction in executive function overall. Similarly ...
The test can provide information about visual search speed, scanning, speed of processing, mental flexibility, and executive functioning. [1] It is sensitive to cognitive impairment associated with dementia , including Alzheimer's disease .
The Hayling Sentence Completion test is a measure of response initiation and response suppression. It consists of two sets of 15 sentences each having the last word missing. In the first section the examiner reads each sentence aloud and the participant has to simply complete the sentences, yielding a simple measure of response initiation speed.
In the neo-Piagetian theories of cognitive development, several variations of the Stroop task have been used to study the relations between speed of processing and executive functions with working memory and cognitive development in various domains. This research shows that reaction time to Stroop tasks decreases systematically from early ...
In contrast, cognitive shifting is a very similar executive function, but it involves conscious (not unconscious) change in attention. Together, these two functions are subcategories of the broader cognitive flexibility concept. Task switching allows a person to rapidly and efficiently adapt to different situations.
The optional subtests provide additional information about cognitive functioning but cannot be used as replacements for core subtests. Block Design - while viewing a constructed model or a picture in a stimulus book, the child uses one- or two-color blocks to re-create the design within a specified time limit.
Brain training (also called cognitive training) is a program of regular activities purported to maintain or improve one's cognitive abilities. The phrase “cognitive ability” usually refers to components of fluid intelligence such as executive function and working memory .
