Document Summary
Intelligence tests: measure a client"s intellectual abilities: achievement tests: measure what a client has accomplished with those intellectual abilities. Defining intelligence: experts do not agree on the definition of intelligence. Theories of intelligence: early 1900"s- charles spearman. Intelligence is represented by: a general factor (g)- a person"s global, overall intellectual ability, found a strong correlation between a wide range of abilities: abstract reasoning, comprehension, problem solving, one or more specific factors /abilities(s) Index scores and subtest scores are reflective of more specific areas of ability: all are administered one-on-one and face-to-face, each subtest is brief (2-10 minutes) and consists of items that increase in difficulty as the subtest progresses. If someone fails a certain number of subtests questions, they move onto the next subtest instead of continuing on: each wechsler has a small number of unique subtests, but most subtests appear in all three.
