NIH Toolbox Oral Symbol Digit Test TASK
Unreviewed

In this test, a coding key with nine abstract symbols is presented – each paired with a number between 1 and 9. Participants are asked to orally indicate which numbers go with symbols that are presented in a long string on the computer screen. The participant is given 120 seconds to call out as many numbers that go with the corresponding symbols as he/she can – without skipping any. This test is administered to ages 8-85 and takes approximately three minutes. The Oral Symbol Digit Test is a measure of processing speed. It can be administered as an accommodation in place of the Pattern Comparison processing Speed Test for those with significant motor limitations in the upper extremities.

CONDITIONS

Experimental conditions are the subsets of an experiment that define the relevant experimental manipulation.

CONTRASTS

You must specify conditions before you can define contrasts.

number correct(edit)

In the Cognitive Atlas, we define a contrast as any function over experimental conditions. The simplest contrast is the indicator value for a specific condition; more complex contrasts include linear or nonlinear functions of the indicator across different experimental conditions.

INDICATORS

No indicators have yet been associated.

An indicator is a specific quantitative or qualitative variable that is recorded for analysis. These may include behavioral variables (such as response time, accuracy, or other measures of performance) or physiological variables (including genetics, psychophysiology, or brain imaging data).
