Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is the psychological refractory period?

    Model answer

    The psychological refractory period is a delay in responding to a second stimulus that arrives while the first is being processed. The brain can deal with only one stimulus at a time.

  2. 2

    Why does the psychological refractory period occur?

    Model answer

    The single channel hypothesis states that information is processed one piece at a time. A second stimulus must wait until the first is dealt with.

  3. 3

    How is the psychological refractory period used in sport?

    Model answer

    A dummy or feint gives an opponent a false first stimulus. The opponent is slow to react to the real move.

  4. 4

    What is anticipation?

    Model answer

    Anticipation is predicting what will happen before it happens. Anticipation reduces reaction time.

  5. 5

    What is spatial anticipation?

    Model answer

    Spatial anticipation is predicting what will happen or where. A goalkeeper predicts which side a penalty will go.

  6. 6

    What is temporal anticipation?

    Model answer

    Temporal anticipation is predicting when something will happen. A sprinter predicts when the gun will fire.
