Measurement of Intelligence

The goal of most intelligence tests is to measure g, the general intelligence factor. Good intelligence tests are reliablemeaning that they are consistent over time, and also demonstrate construct validitymeaning that they actually measure intelligence rather than something else.

Psychologists have devised many tests for the measurement of intelligence. For example:

  • Wechsler Adult Intelligence Scale (WAIS)
  • Stanford Binet IQ test
  • Bayley’s intelligence scale
  • Raven’s progressive matrices test

Wechsler Adult Intelligence Scale (WAIS)

The Wechsler Adult Intelligence Scale (WAIS) is an IQ test designed to measure intelligence and cognitive ability in adults and older adolescents. The original WAIS (Form I) was published in February 1955 by David Wechsler, as a revision of the Wechsler–Bellevue Intelligence Scale, released in 1939.

Classification of Intelligence Tests

Intelligence tests can be classified into two broad categories namely:

  1. Individual tests
  2. Group test

Individual Tests: Individual intelligence tests are administered to individual one by one. They are meant to test the intelligence of one individual at a time. Individual tests of intelligence are of two types:

  • Verbal Individual Intelligence Tests
  • Non-Verbal Individual Intelligence Tests

Group Tests: Group tests are designed to test the Intelligence  of all the students in the group or class. They are given the same directions and have to perform the same activities within the set time- limit. Groups tests of Intelligence can be verbal and non verbal
