Evaluating Intelligence: Subtests of the David Wechsler Test

The subtests of the intelligence test proposed by David Wechsler were meticulously selected based on several key criteria. Firstly, they demonstrate a high correlation with other recognized intelligence tests, affirming their reliability and validity. Secondly, the subtests exhibit a high level of differentiation, allowing for the identification of individual intellectual characteristics. Lastly, they provide invaluable assistance in making accurate psychological and psychiatric diagnoses.

David Wechsler, a distinguished American psychologist, psychiatrist, and psychodiagnostician, developed this test with the goal of creating a tool that equally evaluates both verbal and non-verbal aspects of intelligence. Each subtest is scored and converted to a standardized scale, offering a comparative evaluation of various cognitive abilities. Over the years, the test has undergone numerous changes and updates, with new subtests being introduced and the structure being refined. An example of this evolution is the modification of the WPPSI, designed for younger children. Initially introduced in 1967, it has been revised multiple times—in 1989, 2002, 2003, and 2012.

Today, the Wechsler test exists in three primary versions: the WAIS for adults, the WISC for children and adolescents, and the WPPSI for children aged 4 to 6 years. These versions enable the test to be adapted to different age groups, enhancing its accuracy and relevance.

The Wechsler test assesses several key indicators of intelligence. For instance, it separately evaluates verbal and non-verbal intelligence, revealing the balance between these two aspects. This is crucial as it helps to identify which component is more developed and requires less compensation. The Intelligence Quotient (IQ), calculated based on these two scales, provides a comprehensive picture of a person’s intellectual abilities.

Each of the 11 subtests in the original version of the test plays a unique role in assessing various aspects of intelligence. These subtests can be divided into those that evaluate verbal skills and those aimed at assessing non-verbal abilities. For instance, a verbal subtest might evaluate the ability to understand and use language, while a non-verbal subtest might include tasks involving logical reasoning and spatial perception. Consequently, the Wechsler test provides a comprehensive and detailed analysis of intelligence, helping to identify both strengths and areas needing improvement.
