Directional Choice Reaction Test
Measure visual discrimination and choice response speed
Measure choice reaction time and directional accuracy with PULSE's arrow task, testing how quickly you respond to visual direction cues.
What is Choice Reaction Time?
Choice reaction time requires identifying a specific stimulus and selecting the matching response action among multiple options.
Unlike simple reaction tests with a single trigger, choice tasks engage sensory identification, cognitive spatial mapping, and motor selection.
How the Test Works
The directional test presents 10 trials featuring arrow stimuli facing Up, Down, Left, or Right.
Respond as quickly and accurately as possible using corresponding arrow keys or on-screen directional buttons.
- 10 discrete stimulus trials
- Four cardinal directions randomized per trial
- Foreperiod delay between 1000ms and 3000ms
Speed and Accuracy Balance
Performance is evaluated across both mean response time on correct choices and overall directional accuracy percentage.
Scope and Testing Factors
Physical keyboard layout, key switch travel, and touch responsiveness affect latency. This assessment serves as an educational benchmark and is not a clinical diagnostic measure.
Frequently Asked Questions
Why is choice reaction time slower than simple reaction time?
Choice tasks require sensory discrimination and action selection stages before motor command initiation, adding cognitive processing time.
