The TAMA was designed specifically for the Longitudinal Study as a nonverbal test of general knowledge. The test requires the child to point to the correct picture among three alternatives in response to a question. The two practice items and 25 test items are printed on bound cards, mostly in black and white. Items can be classified as follows: social environment, physical environment, health and safety, practical arts, consumer behavior, sports and games, literature, and TV and comics. The test takes about ten minutes. Each item was scored as correct, incorrect, refusal, or indeterminate. The TAMA correlated with a wide range of cognitive perceptual measures and correlated highly with a factor representing general information-processing skills. Its internal reliability, convergent validity, ease of administration, and reduced emphasis on productive skills suggest its usefulness as a supplementary index in test batteries aimed at tapping cognitive abilities. The significant SES and age effects reflect the expected maturational and experimental influences upon the child's increased assimilation of knowledge from his environment.
