Intelligence tests used today are evolved from

the work of Alfred Binet.

The first tests were created to measure ‘mental

functions’

In 1905, Binet and Simon published their test,

which had questions in order of increasing

difficulty.

If a child scores the average number of correct

items for their age group then their mental age

would match their chronological age

The participants chronological age is measured

in years and months.

STANFORD -BINET TEST OF INTELLIGENCE

After Binet died in 1911, his test was translated into English and adapted for the US.

Lewis Terman, a lecturer at Stanford University adapted the questions so they were

suitable for American students and also adults.

In 1916, the test was republished as the Stanford-Binet Intelligence Scale.

The most recent revision of the test was in 2003, this is done to make sure items are

still relevant

Now five cognitive abilities are measured for people between 2-85+ years

The abilities are;• Fluid reasoning knowledge • Quantitative reasoning• Visual-spatial processing • Working memory

One of the most widely used is the intelligence test

developed by David Wechsler in 1939.

Though devised in America, they have been adapted for use

in Australia

The best known scales are WAIS-IV (Wechsler Adult

Intelligence Scale) and the WISC-IV (Wechsler Intelligence

Scale for Children)

An IQ score can be calculated from the total combined

performance on the four components of the test.

Those components are; • Verbal comprehension• Perceptual reasoning• Verbal memory • Processing speed.
