Week 2 Flashcards
3 types of neuromyths
Nonsense: All experts agree
Lack of facts: Experts on this topic agree
Controversy: Experts on this topic are debating
Reasons for neuromyths
Bandwagonitis
Taking over ideas of friends and colleagues because they said so
What acute exercise does to your brain
› Increase in cerebral blood flow
› Increase in availability of neurotransmitters:
dopamine and noradrenaline
› Increase in Brain Derived Neurotrophic Factor
(BDNF) availability
Promotion of neurogenesis
Promotion of growth of nerve cells in the brain
› Greater activity in brain areas related to executive functions and attention regulation
Wide range achievement test (WRAT)
Test for academic performance
Acute effects on cognition: results
Increased brain activity on incompatible trials
Improved accuracy on flanker task
Improved reading comprehension performance (WRAT)
But NOT on math performance
-Its better to train executive functions to improve them
Exercise supports but does not improve executive functions
How to be a critical consumer of MBE research
Brain explanations are very appealing
› Brain findings do not apply to other levels: cognition, academic performance, behavior
› Lab findings do not apply to real environments
› Do not overgeneralize: acute effects, in children
› Only one study -> accumulating evidence is necessary
The SANE effect
The seductive allure of neuroscience explanations
- Circular explanations are judged more credible when combined with brain info
Chronic physical exercise has beneficial effects for:
-Symptoms of ADHD as rated by parents and teacher
-Executive functioning
-Increased frontal brain activity
-Motor functioning
Social and emotional functioning
-Behaviour problems
Antecedent based intervention
Prevention of externalizing behaviours
-Extra recess time
-Multiple desks
-Motor breaks
-Stability balls
Consequent based interventions
Strategies for after the behaviour takes place
-Running errands
-Toys for fidgeting
-Exercise/dancing breaks as group reinforcer
Neuropsychological tests prior to 1990
Halstead-Reitan
Luria-Nebraska batteries
Differences between NEPSY and NEPSY II
Extended test to 16yrs 11 months
Includes new subtests and removed domain scores
NEPSY
-Developmental
-First neuropsychological assessment battery specifically for children age 3-12
-Lurian and process oriented approach
-results interpreted in both qualitative and quantitative matter
Purposes of NEPSY-II
-Assess brain damage even if cause is not known
-Use as a LT follow up
-Identify patterns of deficiencies that are consist with research on neurodevelopmental disorder
-To identify strengths and weaknesses that can be directly linked to prescriptive interventions
