The executive functions are among the last mental functions to reach maturity. This is due to the delayed maturation of the prefrontal cortex, which is not completely myelinated until well into a person's third decade of life. Development of executive functions tends to occur in spurts, when new skills, strategies, and forms of awareness emerge.
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]
Each form of the BRIEF parent- and teacher- rating form contains 86 items in eight non-overlapping clinical scales and two validity scales.These theoretically and statistically derived scales form two indexes: Behavioral Regulation (three scales) and Metacognition (five scales), as well as a Global Executive Composite [6] score that takes into account all of the clinical scales and represents ...
Executive functions are limited in capacity and accountable for the initiation, consolidation, regulation, and inhibition of cognitive, language, motor and emotional processes. [2] These processes underlie such functions as self-evaluation, planning, problem solving, controlling impulses and attention, and strategic selection or sequencing of ...
This test consists of 30 points and takes 10 minutes for the individual to complete. The original English version is performed in seven steps, which may change in some countries dependent on education and culture. The basics of this test include short-term memory, executive function, attention, focus, and more.
Therefore, there are no aggregate measures or composite scores for an examinee's performance. A vast majority of these tests are modified, pre-existing measures (e.g., the Trail Making Test); however, some of these measures are new indices of executive functions (e.g., Word Context Test).
This has led research to investigate the possibility that executive functioning is broken down into multiple processes that are spread throughout the frontal lobe. [6] Further disagreement comes from the syndrome being based on Baddeley and Hitch's model of working memory and the central executive, which is a hypothetical construct. [2]
Andrews concludes that it is "the most thought-provoking book on organization and management ever written by a practicing executive." [2]: xxi He contrasts Functions of the Executive with the "classical" approaches to organizations found in books such as Principles of Management by Harold Koontz and Cyril J. O'Donnell.
