Question 1

Which of the following best describes 'reaction time' (RT) in the context of human movement performance?

Accepted Answer

The interval between the onset of a signal (stimulus) and the initiation of the required response.

Question 2

A football player must react as quickly as possible after the referee blows the whistle. Which performance measure is most relevant in this scenario?

Accepted Answer

Reaction time (RT)

Question 3

Which equation correctly represents 'response time' in terms of reaction time (RT) and movement time (MT)?

Accepted Answer

$response\ time = RT + MT$

Question 4

In a driving simulator, a student must brake when a red light appears, but ignore blue and green lights. What type of reaction time is being measured?

Accepted Answer

Discrimination reaction time

Question 5

Which of the following best defines 'movement time' (MT)?

Accepted Answer

The interval between the initiation of a movement and its completion.

Question 6

A laboratory test requires a subject to press a button as soon as a light appears. What type of reaction time is this?

Accepted Answer

Simple reaction time

Question 7

Which scenario best illustrates 'choice reaction time'?

Accepted Answer

Pressing a specific button depending on whether the light is red, blue, or green.

Question 8

If a person’s reaction time (RT) is $0.25\ s$ and movement time (MT) is $0.40\ s$, what is their response time?

Accepted Answer

$0.65\ s$

Question 9

Why is it important to separate reaction time (RT) and movement time (MT) when assessing human performance?

Accepted Answer

Because RT measures the time to initiate a response, while MT measures the time to complete the movement, allowing for more precise analysis.

Question 10

In a discrimination RT test, which of the following is true?

Accepted Answer

The subject must respond only to a specific stimulus and ignore others.

Question 11

Which of the following best describes the difference between simple RT and choice RT?

Accepted Answer

Simple RT involves one stimulus and one response; choice RT involves multiple stimuli and multiple possible responses.

Question 12

A student in a driving simulator must respond to a stop sign by pressing the brake, but ignore yield and speed limit signs. What type of RT is being measured?

Accepted Answer

Discrimination RT

Question 13

Which of the following equations correctly calculates movement time (MT) if response time is $0.80\ s$ and reaction time is $0.30\ s$?

Accepted Answer

$MT = response\ time - RT$

Question 14

Which of the following is NOT a factor that can affect reaction time (RT) in a laboratory setting?

Accepted Answer

The color of the subject’s clothing

Question 15

In a choice RT test, if the red light requires pressing the index finger, blue the middle finger, and green the ring finger, what is being measured?

Accepted Answer

The ability to select the correct response based on the stimulus presented

Question 16

Which of the following best explains why RT and MT are measured separately in sports performance analysis?

Accepted Answer

Because RT reflects decision-making speed, while MT reflects physical execution speed.

Question 17

A subject is instructed to press a button only when a green light appears, ignoring red and blue lights. What type of RT is this?

Accepted Answer

Discrimination RT

Question 18

If a person’s movement time (MT) is $0.35\ s$ and their reaction time (RT) is $0.20\ s$, what is their response time?

Accepted Answer

$0.55\ s$

Question 19

Which of the following is a real-world example of discrimination RT?

Accepted Answer

A driver braking only when a stop sign appears, ignoring other road signs.

Question 20

Which performance measure is most useful for evaluating how quickly a person can initiate a movement after a signal?

Accepted Answer

Reaction time (RT)

Reaction Time and Movement Time in Human Performance
