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 test scores and the following summary scores: Total Cognition Composite, Fluid Composite (includes Dimensional Change Card Sort, Flanker Inhibitory Control and Attention, Picture Sequence Memory (Form A), List Sorting Working Memory, and Pattern Comparison tests), and Crystallized Composite (includes Picture Vocabulary and Oral Reading Recognition tests).

The NIH Toolbox Early Childhood Cognition Battery is recommended for ages 4-6. It produces individual test 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.

Oral Reading Recognition Test

Cognition: Language, Expressive

Ages: 7+

Test Time: 4 minutes

An assessment of reading decoding skills and crystalized abilities. Participants are asked to read aloud letters and words, pronouncing them as accurately as possible.

Picture Vocabulary Test

Cognition: Language, Receptive

Ages: 3+

Test Time: 3 minutes

An assessment of receptive vocabulary administered in a computer-adaptive test (CAT) format. Participants must choose which of four pictures best represents a word presented via audio.
