Simple Reaction Time
System Requirements
Minimum: 800×600
Recommended: 1024×768
Description
A simple reaction time task where a single stimulus (an 'X' or mouse button prompt) appears at a specifiable delay from the previous response. Measures basic alertness and motor response speed across multiple blocks with breaks.

Data Output
Creates two data files: (1) SimpleRT-<subnum>.csv with trial-level data including subnum, block number, trial number, foreperiod (delay), response time, stimulus type, absolute start time, and response mechanism used; (2) SimpleRT-report-<subnum>.txt with summary statistics including minimum, median, maximum, mean, and standard deviation of response times, number of anticipations (responses faster than 100ms), and separate statistics by block.
Example Data
| subNum | block | trial | time0 | delay | delay2 | rt | resp1 | resp2 |
|---|---|---|---|---|---|---|---|---|
| P001 | 1 | 1 | 2973 | 1500 | 1500 | 402 | NO_RESPONSE | x |
| P001 | 1 | 2 | 4875 | 2500 | 2501 | 245 | NO_RESPONSE | x |
| P001 | 1 | 3 | 7622 | 2000 | 2001 | 231 | NO_RESPONSE | x |
