The Terman Merril Test, also known as the Terman Merril Intelligence Test or the Terman Merril Progressive Matrices Test, is an assessment designed to measure a person's general intelligence. Developed by American psychologist Lewis M. Terman and his colleague Maude A. Merril, this test is widely used in educational, clinical and work settings. It is based on Charles Spearman's theory of mental abilities, which postulates the existence of a general intelligence factor (g), as well as Thurstone's theory of verbal comprehension and abstract reasoning. The Terman Merril Test is characterized by using matrices and figures as visual stimuli to evaluate various cognitive skills, such as logical reasoning, spatial perception and problem solving.
Parts of the Terman Merril Test
The Terman Merril Test is made up of several parts that evaluate different aspects of a person's intelligence. Each part is designed to measure specific skills and provide a global view of the cognitive abilities of the individual evaluated. The main parts of the Terman Merril Test are described below:
1. Complete Matrices
Complete Matrices are one of the fundamental parts of the Terman Merril Test. They consist of a series of matrices with a missing piece that the individual must complete by choosing the correct option among several alternatives. This test evaluates logical reasoning ability, visual perception, and abstract problem solving. Participants must identify patterns and relationships between the figures presented to infer which piece fits in the empty space.
2. Incomplete Matrices
Incomplete Matrices are similar to Complete Matrices, but in this case, the figures presented are partially empty and the individual must identify the missing piece to complete the pattern. This part of the test evaluates the participant's abstraction capacity, verbal fluency and inference capacity. It requires thinking creatively and finding solutions to ambiguous situations.
3. Reasoning Matrices
The Reasoning Matrices consist of a series of matrices in which the individual must identify the underlying logic and find the figure that follows the correct sequence. This part of the test evaluates the participant's abstract reasoning ability, spatial perception and deduction ability. It requires understanding complex patterns and applying logical rules to solve the problems posed.
4. Completion Matrices
In Completion Matrices, the participant must identify the figure that correctly completes a series of visual patterns presented in the form of matrices. This part of the test evaluates the participant's visual perception capacity, selective attention and analysis capacity. It requires observing the figures in detail and finding the relationship that exists between them to select the correct option.
5. Special Matrices
The Special Matrices are an additional part of the Terman Merril Test that includes more complex and abstract figures to evaluate the participant's ability to solve more difficult problems. This part of the test tests the individual's capacity for abstraction, cognitive flexibility and creativity. It requires innovative thinking and the ability to find original solutions to complex problems.
Tests of the Terman Merril Test
In addition to the aforementioned parts, the Terman Merril Test includes a variety of tests that allow evaluating different aspects of intelligence. These tests may be designed to measure verbal comprehension, perceptual speed, visual memory or numerical reasoning ability, among other aspects. Below are some of the most common tests of the Terman Merril Test:
1. Vocabulary Test
The Vocabulary Test evaluates the individual's ability to understand and use a wide range of words and expressions in diverse contexts. This test measures the participant's verbal comprehension, language proficiency, and communication skills. It requires identifying the meaning of uncommon words, understanding verbal analogies and expressing ideas clearly and precisely.
2. Arithmetic Test
The Arithmetic Test evaluates the participant's ability to perform numerical calculations, solve mathematical problems, and understand complex arithmetic concepts. This test measures numerical reasoning ability, calculation speed, and accuracy in solving mathematical problems. It requires applying basic operations, identifying numerical patterns and finding logical solutions to arithmetic problems.
3. Similarities Test
The Similarities Test evaluates the individual's ability to identify similarities between concepts, words or diverse situations. This test measures abstraction ability, cognitive flexibility, and the ability to find relationships between seemingly unrelated elements. It requires identifying analogies, inferring underlying principles and establishing connections between abstract concepts.
4. Memory Test
The Memory Test evaluates the individual's ability to retain and remember information presented visually or verbally. This test measures short-term memory, long-term memory, and the ability to recover previously learned information. It requires remembering sequences of numbers, words or figures, as well as identifying memory patterns and recognizing specific details in the information presented.
5. Reading Comprehension Test
The Reading Comprehension Test evaluates the individual's ability to understand, analyze and synthesize information presented in the form of written text. This test measures reading comprehension, inference capacity, and the ability to extract relevant information from a text. It requires identifying main ideas, inferring implicit meanings and applying reading comprehension strategies to answer questions about the text.
Conclusions
The Terman Merril Test is a useful and reliable tool to evaluate the general intelligence and cognitive abilities of people. Through its different parts and tests, this test allows identifying strengths and areas of improvement in the cognitive performance of the evaluated individuals. The combination of matrices and figures as visual stimuli favors the evaluation of complex skills, such as logical reasoning, spatial perception and resolution of abstract problems.
In the educational field, the Terman Merril Test can help identify students with high intellectual abilities and design personalized educational programs to meet their specific needs. In the workplace, this test can be useful to select candidates with adequate cognitive skills for certain jobs and predict their performance in activities that require a high level of intelligence.
In conclusion, the Terman Test Merril is a versatile and widely used tool in psychology to evaluate intelligence objectively and systematically. Its focus on the evaluation of key cognitive skills makes it a valuable tool to better understand the functioning of the human mind and promote the personal and professional development of those evaluated.
