Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Performance test
Option (1) Performance test — Correct. Performance tests require subjects to manipulate objects and other materials to perform a task, and written language is not needed. In Kohs’ Block Design Test the subject arranges wooden blocks within a time period to produce a given design, so it is a performance test.
Option (2) Non-verbal test — Incorrect. Non-verbal tests use pictures or illustrations as test items, as in Raven’s Progressive Matrices, where the subject chooses the figure that completes a pattern. Kohs’ test makes the subject handle real blocks, which places it in the separate category of performance tests.
Option (3) Verbal test — Incorrect. Verbal tests require verbal responses, either orally or in writing, so they can be given only to literate people. Arranging blocks needs no words.
Option (4) Aptitude test — Incorrect. An aptitude test predicts what an individual will be able to do if given training in a specific field, such as mechanical or musical aptitude. Kohs’ Block Design Test is a test of intelligence, classed by how the items are answered.
NCERT (2025-26): “Verbal, Non-Verbal, or Performance Tests … An intelligence test may be fully verbal, fully non-verbal or fully performance-based, or it may consist of a mixture of items from each category. Verbal tests require subjects to give verbal responses either orally or in a written form. Therefore, verbal tests can be administered only to literate people. The non-verbal tests use pictures or illustrations as test items. Raven’s Progressive Matrices (RPM) Test is an example of a non-verbal test. In this test, the subject examines an incomplete pattern and chooses a figure from the alternatives that will complete the pattern. A specimen item from RPM is given in Figure 1.3. … Performance tests require subjects to manipulate objects and other materials to perform a task. Written language is not necessary for answering the items. For example, Kohs’ Block Design Test contains a number of wooden blocks.…” |
