Determination
Multi-stimulus choice reaction under rising load
Five coloured lights and two tones, each with its own key. Each stimulus waits only so long: keep up and the window shortens, fall behind and it lengthens, and the last minute runs faster than most people can sustain. 20 seconds of practice, then four scored minutes. The Vienna Test System is commercial software; this reproduces the construct it measures - choice reaction under rising load - not its screens.
Free run: the first 20 seconds
You will sit the first 20 seconds of this test and get your score for them. Unlock it for $6.99, or every test for $25, to sit the full paper and see the breakdown behind the score. What unlocking adds
Before you start
- 20 seconds of practice (not scored), then 20 seconds where the pace follows your answers. No breaks.
- Press the key for each light or tone as it arrives. The next one comes as soon as you answer or its time runs out. A wrong key and a miss cost the same mark.
- Turn your sound on - two of the seven stimuli are tones.
- Leaving this tab voids the attempt.
