Cognition
Cognition refers to the mental processes involved in gaining knowledge and comprehension, such as thinking, knowing, remembering, judging, and problem-solving. These higher-level functions of the brain encompass language, imagination, perceptions, and the planning and execution of complex behaviors.
The NIH Toolbox Cognition Battery, recommended for ages 7+, consists of tests of multiple constructs. It yields individual measure scores and the following summary scores: Cognitive Function Composite Score, Fluid Cognition Composite Score (includes Dimensional Change Card Sort, Flanker, Picture Sequence Memory (Form A), List Sorting, and Pattern Comparison measures), and Crystallized Cognition Composite Score (includes Picture Vocabulary and Oral Reading Recognition measures).
The NIH Toolbox Early Childhood Cognition Battery is recommended for ages 3-6. It produces individual measure scores and an Early Childhood Composite Score (includes Dimensional Change Card Sort, Flanker, Picture Sequence Memory (Form A), Picture Vocabulary, and Speeded Matching).
Other cognition tests can be administered to understand the participant’s functioning, but are not required for the calculation of the composite scores.
