How it works

Arrows left/right. Tap that side (keys A/L or arrows). If STOP flashes, do not tap. About 36 trials. Stop-signal research estimates SSRT with staircase delays. This fixed-cue toy does not compute SSRT and is not an IQ.

Same as go/no-go?Related family, different URL. Go/no-go is a different mapping.
Do false alarms mean ADHD?No. Web toys are not diagnostic.
