Reaction Time (RTI)
Reaction Time provides assessments of motor and mental response speeds, as well as measures of movement time, reaction time, response accuracy and impulsivity.
Administration time
3 minutes
Task format
The participant must select and hold a button at the bottom of the screen. Circles are presented above (one for the simple mode, and five for the five-choice mode.) In each case, a yellow dot will appear in one of the circles, and the participant must react as soon as possible, releasing the button at the bottom of the screen, and selecting the circle in which the dot appeared.
Outcome measures
Outcome measures are divided into reaction time and movement time for both the simple and five-choice variants.
