Question 1

What is motor behavior?

Answer 1

Motor behavior is any action or behavior that results in movement.

Question 2

What is motor control?

Answer 2

Motor control is the ability of an organism’s nervous system to regulate movement.

Question 3

What are the three stages of information processing?

Answer 3

Stimulus recognition: Thinking about what is about to happen and recognizing the stimulus.

Response selection: Responding to the stimulus (e.g., rotating the arm, opening the hand, catching a ball).

Response programming: Programming the response to the stimulus.

Question 4

What is the term used for the process of converting short-term memory into long-term memory?

Answer 4

encoding

Question 5

What is contextual interference?

Answer 5

Contextual interference refers to improving a small skill that improves the overall larger skill.

Question 6

What is the challenge point in learning?

Answer 6

The challenge point is the relationship between learning and the difficulty of a task, where there is an optimal learning level that occurs when the difficulty is appropriately balanced.

Question 7

What is the difference between closed-loop and open-loop theories?

Answer 7

Closed-loop theory: Involves receiving feedback during the task to adjust movements and enhance accuracy.

Open-loop theory: Does not involve feedback during the task; movements are pre-programmed.

Question 8

True or False: Closed-loop theory enhances the accuracy of muscle actions to improve a task.

Answer 8

true

Question 9

What is clinical biomechanics?

Answer 9

Clinical biomechanics focuses on improving a person’s movements in a clinical setting.

Question 10

What is sport biomechanics?

Answer 10

Sport biomechanics focuses on improving movement and performance in sports contexts (e.g., running, jumping).

Question 11

What does the majority of human movement refer to?

Answer 11

general motion

Question 12

What are the two types of translation in linear movement?

Answer 12

Curvilinear motion: Movement along a curved path.
Rectilinear motion: Movement along a straight line.

Question 13

In which plane of movement does abduction and adduction occur?

Answer 13

frontal plane

Question 14

In which plane do push-ups, lunges, and squats occur?

Answer 14
