executive functions psychology

cognitive control, self-regulation, creativity, attention, reasoning, working memory, fluid intelligence, inhibitory control, task switching, mental flexibility, There is clear evidence that parents can and do influence children. Dopamine modulation of the prefrontal cortex is responsible for the efficacy of dopaminergic drugs on executive function, and gives rise to the Yerkes Dodson Curve. Primarily derived from work examining behavioral inhibition, it views executive functions as composed of four main abilities. The posterior dorsal anterior cingulate cortex (ACC) is next in the cascade, and it is responsible for response selection. Second, inhibition is one's capacity to supersede responses that are prepotent in a given situation. Executive function describes a set of cognitive processes and mental skills that help an individual plan, monitor, and successfully execute their goals. Situations that require the overcoming of a strong habitual response or resisting temptation. For example, in a typical study, Liu and coworkers[84] presented subjects with arrays of dots moving to the left or right, presented in either red or green. Russell Barkley proposed a widely known model of executive functioning that is based on self-regulation. Figure 4: My current view of the complex and multiple links between working memory (WM) and long-term memory (LTM). These skills include self-control, working memory, and mental flexibility. The basis of 'higher-level' cognitive functions such as inhibition, flexibility of thinking, problem solving, planning, impulse control, concept formation, abstract thinking, and creativity often arise from much simpler, 'lower-level' forms of cognition and behavior. [citation needed] Other evidence from single-cell electrophysiology in monkeys implicates ventrolateral PFC (inferior prefrontal convexity) in the control of motor responses. Snapshot: What Executive Function Is Such functions allow people to do things like follow … [52], Yet another model of executive functions is a problem-solving framework where executive functions are considered a macroconstruct composed of subfunctions working in different phases to (a) represent a problem, (b) plan for a solution by selecting and ordering strategies, (c) maintain the strategies in short-term memory in order to perform them by certain rules, and then (d) evaluate the results with error detection and error correction. There are five types of situation where routine behavior is insufficient for optimal performance, in which the executive system comes into play: 1. planning or decision making; 2. error correction or troubleshooting; 3. novel situations with unrehearsed reactions; 4. dangerous or technicall… [33][34] However, similar to patterns in childhood development, executive functioning in preadolescents is limited because they do not reliably apply these executive functions across multiple contexts as a result of ongoing development of inhibitory control.[25]. Executive functions are flexible, goal-directed, and adaptive cognitive functions As predicted, participants that had a strong bias toward spatial information had more difficulty paying attention to the semantic information and elicited increased electrophysiological activity from the ACC. “Executive functions” is an umbrella term for functions such as planning, working memory, inhibition, mental flexibility, as well as the initiation and monitoring of action. To measure one's processes researchers, use their heart rate and or respiratory rates. Executive function is a broad set of mental skills that are important for achieving goals and interacting with others. This literature review examines theories of executive functioning and the associated assessment instruments.
