Which of the following intelligence tests is a non-verbal intelligence test?

Question

Accepted Answer

Raven's Progressive Matrices Test is a non-verbal intelligence test, which is why Option 2 is the correct answer. This test is designed to measure abstract reasoning and is considered a good estimate of fluid intelligence. It consists of visual geometric designs with a missing piece, and the task is to identify the correct piece that completes the pattern. Since it does not rely on language skills, it is particularly useful for assessing individuals from different linguistic backgrounds or those with speech or hearing impairments.

Now, let's examine why the other options are incorrect:

1. **Army-alpha Test**: This test was developed during World War I to assess the intellectual and emotional functioning of soldiers. It is a verbal test that includes tasks such as following oral directions, arithmetic problems, and analogies, making it unsuitable as a non-verbal intelligence test.

3. **Binet-Simon Test**: This is one of the earliest intelligence tests, developed by Alfred Binet and Théodore Simon. It primarily involves verbal tasks, such as vocabulary and comprehension questions, to assess cognitive abilities, which makes it a verbal rather than a non-verbal test.

4. **Jalota General Mental Ability Test**: This test is used to measure general mental ability and includes a variety of verbal tasks. It assesses different cognitive functions through language-based questions, which disqualifies it as a non-verbal intelligence test.

In summary, Raven's Progressive Matrices Test is the only option among the given choices that is specifically designed as a non-verbal intelligence test, making Option 2 the correct answer.
