Chapter 9 Intellectual And eduactional Assessment Flashcards
Intelligence test
Measure a clients intellectual abilities
What you have done with your raw potential
Achievement tests
Measure what a client has accomplished with those intellectual abilites
Study you learn in school
Hierarchical model of intelligence
Specific abilites exist and are important, but they are all at least somewhat related to one another and to a global, overall intelligence
Wechsler intelligence tests
Most commonly used measures
WAIS-IV ages 16 to 90
WISC-V ages 6 to 16
WPPSI-IV ages 2 and 6 months to 7 and 3 months
All wechsler intelligence scales yield
A single full-scale intelligence score
Four index scores
Specific sub test scores
Wechsler Intelligence Scales
Four index Scores
Verbal Comperhension Index
Perceptual Reasoning Indez
Working Memory Index
Processing Speed Index
Verbal Comperhension Index
A measure of verbal concept formation and verbal reasoning
perceptual reasoning index
A measure of fluid reasonings, spatial processing and visual motor integration
Working memory index
A measure of the capacity to store transform and recall, incoming information and data stored in short-term memory
processing speed index
A measure of the ability to process simple or rote information rapidly and accurately
processing speed index
A measure of the ability to process simple or rote information rapidly and accurately
Wechsler intelligence scales
normative data 2000 people US census
IQ scores reflect intelligence quota
Strong psychometric properties
similarities the Stanford Bennett intelligence scale have to the Wheler test
administered face-to-face, and one on one
hierarchical model of intelligence
same mean 100 and standard deviation 15
strong reliability and validity data
Differences the Stanford Bennett intelligence scale have from the Wetzler test
covers entire lifespan in one test
Normative sample matches US census data, but also includes normative data from individuals with more specific disorders for comparison
Each test has a greater number of very easy and very difficult items
Difference between intelligent test, and a test of achievement
intelligent test are designed to assess an individuals cognitive capacity when an individual CAN accomplish
Test of achievement are designed to measure what the individual HAS accomplished
