Reaction time

Question 1

Reaction time, and example

Answer 1

Time taken from onset of a stimulus to the onset of a response (involves no movement)

Eg. Period from hearing the gun to push of blocks

Question 2

Movement time and example

Answer 2

Time taken to complete the task (after info has been processed)

Eg. moving

Question 3

Response time and example

Answer 3

• The time taken from the onset of a stimulation to the completion
• (Response time= Reaction time + Movement time)
  Eg. Time between hearing gun and hitting the tape

Question 4

Simple reaction time

Answer 4

The specific response to one specific stimulus
(fast as it only has one stimulus to think about)

Eg. the starter gun at the beginning of the race

Question 5

Choice reaction time

Answer 5

Choosing from lots of stimuli takes longer so response is
slower
Eg. in a team game, make decision from varying stimuli

Question 6

Hicks law

Answer 6

A Response time increases as number of choices increase
Eg. Serving in tennis- mix up the serves (slice etc)- so the opposition can’t predict

Question 7

Psychological refractory period

Answer 7

• A DELAY when a second stimulus is presented before the first has been processed
• Performer freezes for a split second until second stimulus is processed

Eg. a dummy skill in football

Question 8

Single channel hypothesis

Answer 8

A Stimuli can only be processed
ONE AT A TIME. Therefore, a second stimulus must wait until the first has been processed

Question 9

Anticipation

Answer 9

• When a performer tries to pre judge a stimulus by trying to work out what is happening before it does.
• Performers may use information from the environment/ cues like body language

Eg. researching opponents cues etc prior to the game to gain an advantage

Question 10

Temporal anticipation

Answer 10

Pre judging WHEN the stimulus is about to happen

Question 11

Spatial anticipation

Answer 11

Pre judging WHERE the stimulus is about to happen and WHAT it is

Question 12

How to improve response time (4)

Answer 12

• Use mental practice
• Train specific stimulus expected
• Learning to focus and concentrate to pick up stimulus early
• Improving fitness

Question 13

How does mental practice improve response time?

Answer 13

Going over the task in the mind prior to the action. Response preparation process is improved and the action can be predicted so much quicker.

Good for closed skills and serial skills when the environment is predictable

Question 14

How does training the specific stimulus expected in a game improve response time?

Answer 14

Goal keeper practicing penalties to the left if the opposition taker is left footed

Question 15

How does learning to focus and concentrate in a game to pick up stimuli early improve response time?

Answer 15

Can do this by making the stimulus intense making areas out, louder stimulus/noise or brighter bib

Question 16

How does improving fitness improve response time?

Answer 16

Improved reaction- intense interval training and plyometrics may improve speed and power in the movement part of response
