Read now Improving brain function Like any other organ, the brain is affected by a person's lifestyle, diet, and the amount that they exercise. To improve the health and function of the brain, a person can do the following things. Eat a balanced diet Nuts are high in omega fatty acids and antioxidants, making them beneficial to brain health.
Executive functions are crucial for school success! Inresearchers made a startling discovery: This helps explain why their executive skills are delayed. More simply stated the reduced levels of brain chemistry in this key area explains why students can play video games for hours but struggle to complete their homework in a timely manner.
Before we understood the role of executive functions, parents and teachers were often baffled when students, especially those who were intellectually gifted, teetered on the brink of school failure. When a student had trouble getting started and finishing an essay or math work, it was easy to assume that the student chose not to do the task.
Although scientists have not yet agreed on the exact elements of executive function, two ADHD researchers, Dr. Russell Barkley and Dr. Tom Brown, have given us insightful working descriptions.
Barkley describes executive function as those "actions we perform to ourselves and direct at ourselves so as to accomplish self-control, goal-directed behavior, and the maximization of future outcomes.
The conductor organizes various instruments to begin playing singularly or in combination, integrates the music by bringing in and fading certain actions, and controls the pace and intensity of the music. Additional Research on Executive Functions.
Researchers vary widely in reports about the frequency of these deficits in students with ADHD. Barkley believes that the scores on EF rating scales are a better predictor of real world functioning than the lower EF deficit prevalence rates reported on traditional tests of executive skills.
Barkley, students with ADHD experience roughly a thirty percent developmental delay in some skills such as, organizational and social skills. Basically this means our children appear less mature and responsible than their peers.
To ensure academic success for these students, parents and teachers must provide more supervision and monitoring than is normally expected for this age group.
I refer to this as providing "developmentally appropriate supervision. Belatedly I realized that the demands for executive skills increase exponentially in middle school working independently, organizing oneself, getting started, remembering multiple assignments.
Barkley identified the central role executive function plays in school success, that I finally understood why school was so difficult for my son. Teachers would say, "Alex is very bright; he could make better grades if he would just try harder.
Components of Executive Function Based upon material from Barkley, Brown, and Gioia I have outlined eight general components of executive function that impact school performance: Working memory and recall holding facts in mind while manipulating information; accessing facts stored in long-term memory.
Essential related skill deficits may be mistaken for laziness. Since these common academic challenges such as a writing disability are easily recognizable, teachers are more willing to provide necessary accommodations. However, educators may be reluctant to provide needed supports for essential related executive skill deficits such as disorganization, getting started, and failure to submit completed homework in a timely manner.
Unfortunately, on the surface, failure to perform these tasks looks like a simple choice was made to be lazy and not complete the work. Consequently, parents and teachers must always keep in mind that, first and foremost, this is a neurological problem, not laziness.
Poor Working Memory and Recall Contrary to conventional wisdom, researchers report that working memory skills are a better predictor of academic achievement than IQ scores.
Deficits in working memory and recall negatively affect these students in several areas: Affects the here and now: Affects their sense of past events: Affects their sense of time: Affects their sense of self-awareness: Affects their sense of the future: Not surprisingly, these skills are critical for writing essays and working math problems.
Research studies by Mayes and Calhoun and more recently by Katusic have identified written expression as a major learning problem among students with ADHD percent. Consequently, writing essays, drafting book reports or answering questions on tests or homework is often very challenging for these students.
For example, when writing essays, students often have difficulty holding ideas in mind, acting upon and organizing ideas, quickly retrieving grammar, spelling and punctuation rules from long-term memory, manipulating all this information, remembering ideas to write down, organizing the material in a logical sequence, and then reviewing and correcting errors.
Since learning is relatively easy for most of us, sometimes we forget just how complex seemingly simple tasks really are, for example memorizing multiplication tables or working a math problem.
For example, when a student works on a math problem, he must fluidly move back and forth between analytical skills and several levels of memory working, short-term, and long-term memory.
With word problems, he must hold several numbers and questions in mind while he decides how to work a problem. Next he must delve into long-term memory to find the correct math rule to use for the problem.Anatomy and function of the human brain.
