General Features and Response Times
- Timing resolution of 1 millisecond.
- Response timing is synchronized with the screen display so timing always begins when the screen first begins to draw (eliminates 10-17 milliseconds of random error).
- Works with Windows to pause all other system events while timing is taking place.
- Uses Microsoft’s DirectX to gain the fastest access possible to input events from the keyboard, mouse, joystick and soundcard.
- Optionally define minimum and maximum response times and deliver custom message screens for each when violated.
- Collect multiple response times on a single trial.
- Collect key release response times in addition to key press times.
- Define valid keys for any response.
- Define 'correct' key for any response.
- Optionally require a correct response (see the IAT sample).
