Document Summary
Alfred binet itelligence is a capacity that matters for many aspects of cognitive functioning. Created a test that included a range of tasks. Performance was then assessed with a composite score, summing across these various tasks. Test score was computed as a ratio between mental age and chronological age. The test evaluated a person"s intelligence quotient iq. Wechsler intelligence scale for children (wisc) & wechsler adult intelligence scale (wais) Assess general knowledge, vocabulary, comprehension, perceptual-reasoning scale, working memory, speed of intellectual processing. Based on a person"s ability to analyze figures and detect patterns. Presented with a series of grids, must select an option that completes the pattern in each grid. Designed to minimize influence from verbal skills or background knowledge. Reliability how consistent a measure is. Test-retest reliability an assessment of whether a test is consistent in what it. Intelligence tests have strong test-retest reliability measures to another.
