normal curve of intelligence
mean = SD = ranges <70 70-79 80-89 90-109 110-119 120-129 130+
mean = 100 SD= 15
<70 low 70-79 borderline 80-89 low average 90-109 average 110-119 high average 120-129 superior 130+ very superior

Wechsler scale
define intelligence
the capacity to act purposefully, to think rationally, and to deal with the environment
__ scales of Wechsler
3
WPPSI = weschsler pre-school & primary scale of intelligence 2.6 years to 7.7 months WISC= wechsler adult intelligence scale 6 to 16 years WAIS= wechsler adult intelligence scale 16 years to through adulthood
WAIS-IV =
4
1= verbal comprehension scale
2= perceptual reasoning scale
3=working memory scale
4= processing speed scale
define
verbal comprehension index
measure of verbal abilities
define
processing speed index
mental and motor speed with which peopple can solve non-verbal problems
define
working memory index
concentration, attention and short-term memory
define
perceptual reasoning index
measure of perceptual abilities
An IQ of 70 or less =
coupled with deficits in adaptive functioning will result in a diagnosis of intellectual disability
IQ ranges
mild
moderate
severe
profound
mild = 55-70 moderate = 35-54 severe = 25-34 profound = below 25
WPPSI-IV
2 slightly diff versions depending on age of child
2.6 years to 7.7 years
1= stanford-Binet 5th Edition 2= Raven's progressive Matrices
__ factors that may affect test results
2
1= practical considerations 2= testing across culture/ethnicity
cross-cultural neuropsychology =
ethnicity/race does not cause variability in cognitive test performance but rather are markers for a no. of contributing factors (education etc)
cross-cultural neuropsyc
for clinical neuro-psychologists a primary responsibility is to =
consider the potential influence of these factors on test performance when conducting an evaluation.

2=education
3=premorbid ability
4= testing environment
__ culture-friendly tests

6=the kaufman assessment battery for children
importance of testing for intelligence =
to knwo somone’s level of interlectual functioning in order to choose right candidates
to point of strengths and weaknesses
intelligence = interacts with mental illnesses=> diff ways of understanding the experience and diff ways of coping
