Question 1

Which of the following best distinguishes 'performance' from 'learning' in the context of motor behaviour?

Accepted Answer

Performance is an observable behaviour, while learning is a relatively permanent change in performance due to practice or experience.

Question 2

In archery, which of the following is an example of a performance production measure?

Accepted Answer

Drawing the bow and releasing the arrow.

Question 3

Which method is most appropriate for analyzing the timing and size of muscle contractions during a complex movement?

Accepted Answer

Electromyogram (EMG)

Question 4

A researcher wants to measure the variability or inconsistency of a participant's performance around their own average score. Which error measure should they use?

Accepted Answer

Variable Error (VE)

Question 5

Given the scores 10, 4, -1, and -5 with a target of 0, what is the formula for calculating Constant Error (CE)?

Accepted Answer

$$CE = \frac{\sum (X_i - T)}{n}$$

Question 6

Which of the following best describes Absolute Error (AE)?

Accepted Answer

The mean of the absolute deviations between movement and the target, ignoring direction.

Question 7

A coach wants to assess both the spatial and temporal accuracy of a tennis player's serve. Which performance outcome measure is most appropriate?

Accepted Answer

Combination of spatial accuracy and temporal accuracy

Question 8

Which of the following is a limitation of using human judgement to assess production in high-speed complex movements?

Accepted Answer

It may be unsatisfactory due to difficulty in perceiving relationships between movements.

Question 9

What does a large Constant Error (CE) and a small Variable Error (VE) indicate about a performer’s accuracy and consistency?

Accepted Answer

The performer is inaccurate but consistent.

Question 10

Which formula is used to calculate Total Variability (E or RMS) in performance outcome measures?

Accepted Answer

$$E = \sqrt{\frac{\sum (X_i - T)^2$}{n}}$$

Question 11

A psychologist is interested in measuring blood flow to active brain areas during a motor task. Which method should they use?

Accepted Answer

Functional magnetic resonance imaging (fMRI)

Question 12

If a participant’s scores are all the same distance from the target but vary in direction, what can be said about their CE and VE?

Accepted Answer

CE is small, VE is large.

Question 13

Which of the following is NOT a method for assessing production in motor performance?

Accepted Answer

Measuring the number of successful shots in basketball.

Question 14

A student presses a button on a controller to shoot a zombie in a video game. Which type of accuracy is being measured?

Accepted Answer

Temporal/timing accuracy

Question 15

Which of the following best describes the interpretation of Variable Error (VE)?

Accepted Answer

VE reflects the variability/inconsistency in movement relative to one’s own average performance.

Question 16

Which performance outcome measure would be most useful for evaluating the overall success in achieving a target, considering both magnitude and direction of errors?

Accepted Answer

Total variability (E or RMS)

Question 17

A track coach records the number of laps run during practice. This is an example of which type of performance outcome measure?

Accepted Answer

Response magnitude

Question 18

Which of the following is the correct formula for calculating Absolute Error (AE)?

Accepted Answer

$$AE = \frac{\sum |X_i - T|}{n}$$

Question 19

Which scenario best illustrates the use of high-speed filming and computer analysis in sports psychology?

Accepted Answer

Analyzing the velocity and acceleration of a sprinter’s limbs during a race.

Question 20

If a golfer’s putts are +10, +4, -1, and -5 cm from the hole, what is their Constant Error (CE)?

Accepted Answer

$$CE = \frac{10 + 4 - 1 - 5}{4} = 2$$
