Kohs Block Design Test contains a number of wooden blocks to be arranged in a design within a given time period. This test is an example of:

The correct option is Performance test.

Here is a step-by-step explanation of why this is the correct classification:

1. Understanding the Kohs Block Design Test:
The Kohs Block Design Test is a cognitive assessment where a subject is given a set of physical, multi-colored wooden blocks. The subject's task is to physically manipulate and arrange these blocks to replicate a series of geometric patterns shown on cards within a specified time limit.

2. Defining the Types of Tests:
Let us examine the nature of the options provided to see how they apply to this test:
• Performance Test: These are tests that require the examinee to perform a motor active task or physically manipulate objects (like blocks, pegs, or puzzles) to solve a problem. Since the Kohs Block Design Test relies entirely on the hands-on manipulation of physical wooden blocks, it is a classic example of a performance test.
• Non-verbal Test: While the Kohs test does not heavily rely on language, non-verbal tests can include paper-pencil tests with symbols or pictures. The term "Performance test" is a more specific and accurate description of a test requiring physical construction and motor coordination.
• Verbal Test: Verbal tests require the use of language, written or spoken, to answer questions (e.g., vocabulary or comprehension tests). The Kohs test does not require verbal responses or language skills to solve.
• Aptitude Test: An aptitude test measures a person's potential to acquire specific skills or knowledge. While the Kohs test measures spatial intelligence, its format structure is classified primarily by its administration style as a performance test.

3. Conclusion:
Because the core requirement of the Kohs Block Design Test is the physical manipulation and assembly of wooden blocks to match a design, it is classified as a Performance test.
