Bhatia Battery is used to test which of the following?

CONCEPT: Intelligence tests used to study individual differences are broadly divided into performance (non-verbal) tests and verbal tests. A performance test measures a person's ability predominantly through practical tasks with minimal dependence on reading or writing, and this format is specifically used to assess INTELLIGENCE with reduced dependence on formal language skills -- making it usable with illiterate, hearing-impaired, or non-native-language test takers.

APPLICATION: The Bhatia Battery of Performance Tests, developed by Dr. C. M. Bhatia (1955), is one of the best-known Indian non-verbal intelligence test batteries. It contains five performance sub-tests -- Koh's Block Design Test, Alexander's Pass-Along Test, Pattern Drawing Test, Immediate Memory Test, and Picture Construction Test -- each assessing reasoning, memory, or problem-solving through predominantly performance-based, activity-oriented tasks with minimal dependence on formal reading or writing. Because the battery as a whole measures problem-solving and reasoning ability through this performance-based format, it is used to measure INTELLIGENCE.

CROSS-CHECK -- why not the other options:

- Personality is assessed through projective techniques (e.g., the Thematic Apperception Test or Rorschach Inkblot Test) or self-report inventories that ask a person to describe their own traits and preferences.

- Creativity is assessed through divergent-thinking tasks, such as generating multiple unusual uses for an everyday object (as in the Torrance Tests of Creative Thinking).

- Attitude is measured using rating/scaling instruments such as Likert-type or Thurstone scales that record a person's opinions, beliefs, and dispositions toward an object or issue.

So the Bhatia Battery, being a set of predominantly performance-based cognitive tasks, is a test of intelligence.
