Know the goal in Reaction Challenge
Try Reaction Challenge at your own pace and keep its objective in view. Finish five valid responses. An early click does not count as a completed response; start that attempt again. Look at what changes after your first action. Keep the instructions close while learning this activity. Choose a clear next step rather than rushing through the instructions.
One thing to notice as you play
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. Refer to the controls when needed.
The objective of a round
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. Notice how the game responds to your input.
The order of play
- 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.
Your inputs
Use the on-screen controls with a mouse or touch. Read a button’s label before selecting it. Avoid pressing the same control repeatedly while a move is being processed.
An example to follow
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. Check the stated objective.
Watch out for this
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. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
