Intelligence Scales

Describe the similarities and differences between the Stanford Binet Intelligence Scale and the Wechsler Intelligence Scale.

Intelligence: According to the Oxford Dictionary in psychology terms intelligence is the general mental ability involved in calculating, reasoning, perceiving relationships and analogies. It is also the ability to learning quickly, storing and retrieving information, using language fluently and adjusting to new situations.

Stanford -Binet Intelligence Scale
In 1857-1911 Alfred Binet invented the method of testing intelligence. The Stanford-Binet Intelligence Scale (SBIS) is a standardized test that measures intelligence and cognitive abilities in children and adults, from age two through mature adulthood. It can help in the diagnosis of a learning disability, developmental delay, mental retardation or giftedness. The Stanford-Binet Intelligence Scale is comprised of four cognitive area scores which together determine the composite score and factor scores. These area scores include: Verbal Reasoning, Abstract/Visual Reasoning, Quantitative Reasoning, and Short-Term Memory. The test consists of 15 subtests. These subtests are: vocabulary, comprehension, verbal absurdities, pattern analysis, Quantitative, bead memory, memory for digits, equation building, memory for objects, number series, matrices, copying, paper folding and cutting and memory for sentences. Total testing time is 45-90 minutes, depending on the subject's age and the number of subtests given. Raw scores are converted into a standard age score corresponding to age group, similar to an IQ measure.

Wechsler Intelligence Scale
The Wechsler Intelligence Scale was published in 1939 and consists of three scales:
 The Wechsler Adult Intelligence Scale (WAIS IV) released in 2008
 The Wechsler Intelligence Scale for Children (WISC)
 The Wechsler Preschool and Primary Scale of Intelligence (WPPSI)

Time after time the WAIS IV has been improved. Currently the WAIS IV
