Q

What is REACTION time? What is it made up of?

A

Reaction time is the time between the onset of the first stimulus and the beginning of the response to it.
Reaction time combines:
- The times it takes for the information to be detected
- The time it takes for the detected information to travel to the brain
- The time it takes for the brain to recognise the stimulus
- The time it takes for the brain to initiate movement.

eg. the times it takes to START to respond to the ball travelling towards you in tennis

2
Q

What is MOVEMENT time?

A

The time between the start of the muscular movement and the end of the muscular movement.

eg. The time it takes to physically complete the forhand

3
Q

What is RESPONSE time?

A

Reaction time + Movement time

= RESPONSE time

4
Q

How long is reaction time in humans?

A

Around 0.2 seconds for SImple Reaction time

5
Q

What is SIMPLE reaction time?

A

SIMPLE reaction time refers is how long it takes to react to single stimulus

6
Q

What is CHOICE reaction time?

A

When more choices need to be made (eg. deciding which pass to make) reaction time increases.

7
Q

What is HICKS LAW?

A

HICKS LAW states that reaction time is LINEARLY related to the number of choices.

8
Q

What is SINGLE CHANNEL HYPOTHESIS?

A

SINGLE CHANNEL HYPOTHESIS states that we can only PROCESS one piece of information at a time

9
Q

What is the PSYCHOLOGICAL REFRACTORY PERIOD?

A

The PSYCHOLOGICAL REFRACTORY PERIOD is the time delay created when a second stimulus is presented.

The perfomer has to fully process the first stimulus before he/she can attend to the second. This creates a time delay.

If the first stimulus is a ‘dummy’ or ‘fake’ then the defender has to process it before they can respond to the actual movement.

10
Q

What is ANTICIPATION?

A

ANTICIPATION is where a performer predicts what or when something might happen.

This could reduce the impact of the psychological refractory period.

11
Q

There are 2 types of anticipation. What are they?

A
  1. Temporal - when will something happen

2. Spatial - what will happen

12
Q

How many factors can you think of that might affect response time?
Some will affect the ‘reaction time’ and some will affect the ‘movement time’.

A

Reaction - age, distraction, drugs/medication, alcohol, confusion, stress, intensity of stimulus, impaired vision/audition/kinaesthesis

Movement - age, fitness levels, gross motor abilities, speed of movement etc
