2.2.2. Measurement of Executive Function
intellectual disability
SECONDARY
The Stroop test, n-back task, and task switching were used to evaluate inhibitory control, working memory, and cognitive flexibility, respectively, of adults with a mild intellectual disability before and after the badminton intervention [Inhibitory control was measured using the Stroop test. The Stroop color task was divided into consistent and inconsistent conditions. In the consistent condition, the word presented by the test instrument was the same as its color, and in the inconsistent condition, the word did not match the color. The participants needed to pay more attention to judge the words and avoid choosing the incompatible colors. Working memory was measured using an n-back test, as designed by Aiguo and colleagues [The tests were conducted using E-prime 3.0 software. The participants responded to the stimulus pictures presented by E-prime software, and the software automatically collected the task data. The preprocessing of the executive function data was also completed by the software. The evaluation of executive function included the correct response rate and response times. A faster response time indicated a better executive function. The accuracy (rate of correct responses) was used as a secondary evaluation, with greater accuracy being represented by a higher score.
