Respond to arrows; if a red square appears, stop. Score combines accuracy and speed.
Respond to the arrow direction (Left = ←/1, Right = →/2). If a red square appears, stop and do not respond.
Each correct Go or Stop trial adds a point. Final score uses a speed factor from your mean correct Go reaction time.
The Stop-Signal Task (SST) is a classic paradigm for measuring inhibitory control. Most trials are Go trials: respond left or right based on the arrow. On some trials, a stop-signal (red square) appears and you must withhold your response.
Your points come from correct Go responses and successful stops. Your final score is points multiplied by a speed factor derived from your mean correct Go reaction time. For fair tracking, compare results on the same device and input method.
Score is driven mainly by accuracy (including successful stops). A few stop-errors or wrong-direction presses can reduce points more than small speed gains can compensate.
A little caution can help, but over-slowing reduces the speed factor. Aim for clean responses first, then gradually increase speed while keeping accuracy stable.
Yes. Keyboard latency, browser scheduling, and display refresh can shift measured reaction times. Track progress on the same setup for meaningful comparisons.
No. This is for training and self-tracking only. If you have concerns about attention or impulse control, consult a qualified professional.
