wechsler intelligence test

The Intelligence is sometimes referred to as the cognitive ability of an individual to assess, analyze and then to react accordingly. Scientists agree at different degrees that it is an ability that can be measured.

Different theories can be put together to understand what intelligence actually is –

  • Is it the ability to react to the outside environment?
  • Is it the ability to put forth solutions to a problematic sequence of events?
  • Is it the ability to create new solutions?
  • Is it the ability to comprehend the situation?

Or is it all of the above?

What is Wechsler Intelligence Test?

The Wechsler Intelligence Tests actually comprise of, not one, but three individually conducted intelligence tests that measure the intelligence and different mental and cognitive abilities of individuals from ages 2 years to adulthood. These tests can be categorized as follows,

  • WPPSI-III, The Wechsler Preschool and Primary Scale of Intelligence (3rd edition)

This test is conducted as part of the admission tests for children who fall under the age bracket of 2 years and 6 months to 7 years and 3 months.

  • WISC-IV, The Wechsler Intelligence Scale for Children (4th Edition)

This test is conducted as part of the admission tests for kids who fall under the age bracket of 6 years to 16 years.

  •  WAIS, the Wechsler Adult Intelligence Scale (3rd Edition)

This test assesses individuals who are 16 years or older.

The original Wechsler-Bellevue Intelligence Scale, designed in 1939, has been branched out into the above stated categories for specific testing. The three tests have, therefore, been derived out of the same original test.

The Purpose

The Wechsler IQ Test that is specifically designed for per-schoolers and young children, whether it is the original or revised edition, is administered to help place the children adequately according to their mental capabilities. While it can be used to determine the presence of a God-gifted ability, it can also be effectively used to find a learning disability or perhaps restricted mental development.

The Wechsler IQ Test that has been designed for the adults can assess the presence of a vocational ability, gifted intellectual ability and on the other hand it can also determine whether or not, the individual is affected by organic deficits.

Who Conducts the Wechsler Intelligence Tests?

All of the Wechsler Intelligence Tests are organized and administered by a clinically and professionally trained examiner. He or she can be a certified psychiatrist or psychologist who will not only administer, but also score and interpret the results of the tests.

How Will the Wechsler Tests Be Conducted?

The Wechsler IQ Tests, both for children and adults, are categorized into 5 performance and 6 verbal subtests. Each complete test will take approximately an hour to an hour and a half to administer. The scores are compiled alongside and are accumulated at the end of the test after which a Full Scale IQ score is yielded.
