Executive Function

Dr. Alysa Doyle, a psychologist at the Massachusetts General Hospital, has recently outlined the components or parts of executive function. Executive function is thought process necessary for planning to reach goals and adapting to changes in your environment. Dr. Doyle has listed the components as follows:n1. The ability to inhibit and defer a response.n2. Shifting/cognitive flexibilityn3. Abstract reasoningn4. Organization and planningn5. Working memoryn6. Interference controlnnThe ability to inhibit, means to halt or stop any action or reaction. To defer means to delay an activity until it is properly thought out and acceptable. nnShifting/cognitive flexibility involves the ability of an individual to go from one activity to another without becoming distracted.nnAbstract reasoning is the ability to get ideas from information already learned. An example would be the understanding of a metaphor, a joke or a poem.nnOrganization and planning is somewhat self-explanatory. It is the ability to put things in order so that desired results are usually obtained.nnWorking memory has been defined in the ABLE Glossary and could be separate from executive function. It is the ability to recall or remember facts and use them in day-to-day mental exercises without effort.nnInterference control is the ability to remain undisturbed when newly learned material or behavior does not agree with previously learned material or behavior. It is essential for adapting or developing coping skills.nnDr. Doyle stated that in psychological testing, there are two items called freedom from distraction and block design. When present, these items may well suggest a problem with executive function.nnExecutive function is a problem area in many disorders of learning style, such as, impulsive/compulsive disorders. It can be improved with retraining and medicines.n nNeuropsychological evaluations may prove useful when problems in executive function are thought to be present. These evaluations are done at pediatric developmental centers. n
