An introduction to playing Reaction Challenge
Reaction Challenge gives you a focused activity to play in your browser. Finish five valid responses. An early click does not count as a completed response; start that attempt again. Choose a clear next step rather than rushing through the instructions. Identify the playing area and the controls you need. Keep the game area visible while you use its controls.
Something to practise
Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules. Use the example to check your reasoning.
What you need to achieve
Finish five valid responses. An early click does not count as a completed response; start that attempt again. An attractive position is not enough unless the goal is met. The example below illustrates a decision.
Start here and follow along
- Start a round and wait without clicking.
- When GO appears, click or tap the large target.
- Read your response time and start the next round.
- After five rounds, the game shows the mean time.
The controls to know
Use the on-screen controls with a mouse or touch. Use the control method described here for this activity. Contact us with the game and device if a control does not respond.
One way to understand the rules
A valid 250 ms response counts. Clicking during WAIT is too early and must be repeated. Apply the same reasoning to the position in your own round. Consider the next action carefully.
Keep this in mind
Browser scheduling, screen refresh and input hardware can affect the measurement. It is not a medical test. Take a moment to reassess the position before continuing. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
