The Terman-McNemar Test of Mental Ability is a psychometric assessment used to measure an individual’s intelligence. It was developed by Lewis Terman and his colleague, Robert McNemar, and first published in 1940 (Terman & McNemar, 1940). The test consists of a series of multiple-choice questions designed to measure a person’s general mental ability. It is a useful tool for researchers and clinicians who are interested in assessing the cognitive abilities of individuals.
The Terman-McNemar Test of Mental Ability is a timed test. Participants are given a list of items and asked to select the correct answer from a set of multiple-choice options. The items are designed to measure a variety of cognitive abilities, including verbal comprehension, problem-solving, and abstract thinking. The test takes approximately 30 minutes to complete and can be administered in either a paper-and-pencil or computer-based format.
The Terman-McNemar Test of Mental Ability has been found to be a reliable and valid measure of intelligence. Studies have shown that the test is able to accurately measure intelligence and that it is able to differentiate between individuals of different cognitive levels (Muela, 2011; Stalnaker, 2014). Additionally, the test has good test-retest reliability, meaning that individuals who take the test multiple times will generally get similar results (Terman & McNemar, 1940).
The Terman-McNemar Test of Mental Ability has been used in a variety of settings. It has been used to assess the intelligence of individuals in educational settings, clinical settings, and research studies. It has also been used to compare the cognitive abilities of different groups, such as those with different educational backgrounds or those with different levels of intelligence (Muela, 2011; Stalnaker, 2014).
Overall, the Terman-McNemar Test of Mental Ability is a reliable and valid measure of intelligence. It is a useful tool for researchers and clinicians who are interested in assessing the cognitive abilities of individuals.
