Learners with Attention Deficit Hyperativity Disorder (AD/HD)
Attention-Deficit/Hyperactivity Disorder
Most commonly diagnosed childhood psychiatric disorderGreat deal of controversy and misconceptions“He’ll grow out of it” “It’s just a matter of self-control” “Poor parenting” “Food additives” “Fast-paced culture” “Too much TV and Nintendo”Are psychotropic medications given too much? Too little?
New labels for an old disability?

New labels for an old disability?
Moral deficit, minimal brain dysfunction, hyperkinesis, hyperactivity, ADD ==Attention-deficit/hyperactivity disorder [AD/HD]1902: George Still’s theory of subtle brain injury1917-18: The Great Flu Epidemic – left some children with impaired attention, memory, and impulse control (similar to Still’s patients)BIG ISSUE: free will or determinism?
Definitions
What does IDEA say about AD/HD?Now mentioned directly in new regs under OHI“is due to . . . Attention deficit hyperactivity disorder . . . Adversely affects a child’s educational performance.”Most often, the DSM-IV definition is used:
DSM-IV
“The essential feature of AD/HD is a persistent pattern of inattention and/or hyperactivity-impulsivity that is more frequent and severe than is typically observed in individuals at a comparable level of development.”Before age 7 and for 6 months
Characteristics
AD/HD kids differ from peers in ability to concentrate and control impulses
Not all are hyperactive – some are hypoactiveThree main subtypes of AD/HD: (yes, a slash)1. Predominately inattentive type2. Predominately hyperactive-impulsive type3. Combined (inattentive and hyperactive)
1. Predominately Inattentive type
Trouble paying attentionEasily distractedForgetful and “spacey”DaydreamersConfused, lost in thoughtStares, seems apatheticADDOften girls
Predominately Hyperactive-Impulsive
Cannot seem to sit stillTalk excessivelyHave difficulty playing quietly“Challenging” to parents and teachersBedwetting, sleep problemsTemper tantrums
Combined type
ADHD without the slashAs many as 85% of AD/HD kids are ADHDBarkley feels that inattentive type is significantly different from the hyperactive/impulsive and the combined typesInattentive’s core problem is focused or selective attentionOther 2 have problems with poor goal-directed persistence and interference control (inhibiting distraction)One has problems getting started, other with finishing
A Conceptual Model of Self-regulation Characteristics
Barkley now theorizes that difficulty with behavioral inhibition is the big problem hereBy this, we mean the ability to:A) delay personal gratification or reinforcementB) interrupt an ineffective response to replace it with a more effective behaviorC) Continue with a desirable behavior despite interferenceA,B,C affect executive functions and time perceptionDisability of performance, not skill
What Are These 4 “Executive Functions?”
Not publicly observablePurpose is to internalize behavior to plan for change and the future1. Nonverbal working memory: Allows students to recover auditory, visual, and other sensory images of the past2. Internalization of speech: Ability to talk to yourself, plan what you will do or say, recognize when it is appropriate to speak your thoughts out loud.
More executive functions
3. Self-regulation of affect, motivation, and arousal.Barkley: “lack the drive, in the presence of external rewards, that fuels the individual’s persistence in goal-directed actions.”4. Reconstitution: The skill of analyzing and synthesizing behaviors. Breaking tasks up into component steps
Time Perception
This is also a problem, in addition to executive functionsOverestimate time intervalsPerception that time moves more slowlyProcrastinate – think they have more time
Causes of AD/HD
Too much sugar?Too little sugar?Aspartame?Food sensitivity?Food additives? Colors?Lack of certain vitamins?TV? Video games?Yeast? Lightning?Fluorescent lights?Allergies?
Environmental Explanations
Poor parenting?Research does not support this (Barkley)Often sibs are not AD/HDPerhaps negative behavior of mothers is a reaction to their child’s AD/HD rather than the causeStress in the family? Too short term, really
Biological Explanations
Big area of study right nowTwo areas of research interest:1. Pre-, peri-, and postnatal trauma2. Brain differences resulting from faulty genes
Pre-, peri-, and postnatal trauma
Certain teratogens increase the likelihood that a child will develop AD/HDMaternal smokingAlcohol/Drug abusePoor maternal nutritionMother’s exposure to chemical poisonsAccounts for 20-30% of AD/HD in boys, less in girls
