Identifying Non-Individual Tests

The question asks to identify which options from the list are NOT considered individual tests. Let's analyze each option:

• A. Picture completion test: This is typically a specific task administered to a single person, classifying it as an individual test.
• B. Object assembly test: Similar to picture completion, this involves arranging parts to form a meaningful whole and is usually administered individually.
• C. General mental ability test: This term often refers to a broad assessment measuring overall cognitive capacity. It might represent a category of tests or a composite score derived from multiple tests, rather than a single, discrete individual test.
• D. Test of General comprehension: Like general mental ability, this phrase suggests a broader assessment, possibly encompassing various sub-tests or aspects of comprehension, making it less likely to be a single, standalone individual test.
• E. Raven's Progressive Matrices test: While Raven's Matrices is a well-known measure of fluid intelligence, and often administered individually, in the context of this question and the provided answer, it is grouped with tests considered non-individual. This might be due to its specific focus on non-verbal reasoning or its standardization as a measure of general cognitive ability, distinguishing it from performance-based individual tasks like A and B.

Reasoning for Correct Answer

Based on the analysis and aligning with the provided correct answer:

• General mental ability test (C) is considered a broad classification or composite measure, not a single individual test.
• Raven's Progressive Matrices test (E) is classified as not an individual test within the framework suggested by this question's options and answer.

Therefore, options C and E are identified as NOT being individual tests.

The correct answer is Option D: C and E only.
