Answer 2

1 - postural preparation
2 - prep of limb movement
3 - prep of movement for object control
4 - prep for sequence of movements
5 - rhythmicity prep
6 - spatial coding

Question 3

stabilization occurs in what step of a plan?

Answer 3

postural prep

Question 4

direction, trajectory, and accuracy considerations occur in what step of a plan?

Answer 4

prep of limb movement

Question 5

force control and end state comfort are considered in what step of a plan?

Answer 5

prep of object control

Question 6

orientation in space is considered in what step of a plan?

Answer 6

spatial coding

Question 7

what are the two theoretical approaches to movement prep?

Answer 7

information processing and perception-action coupling

Question 8

what are the three stages of info processing?

Answer 8

input, decision making, and execution

Question 9

input stage

Answer 9

stimulus identification
- perceive/interpret input situational factors

Question 10

decision making

Answer 10

response selection
- compare with existing memory stores and make decisions

Question 11

execution

Answer 11

response programming
- organize and execute selected response

Question 12

____________ suggests perceptual processes traverse a series of mental processes, linked with memory and influenced by arousal, and results in a decision to act.

Answer 12

expanded information processing model

Question 13

in ______ environment and task are perceived or interpreted directly based on affordances

Answer 13

perception action coupling

Question 14

affordances

Answer 14

action possibilities of environment and task in relation perceiver’s capabilities

Question 15

what does perception action coupling emphasize?

Answer 15

• emerging interaction between the performer and the environment
• coordination of perceptual and motor systems
• organization of action is specific to the task and environment

Question 16

what does perception action coupling de-emphasize?

Answer 16

the need for stored representations

Question 17

as the learner gains experience perceptual variables couple with the dynamics of the movement so that a distinct coordination patter can be ______________

Answer 17

• reproduced and modified as necessary

Question 18

response time is comprised of_________________

Answer 18

reaction time and movement time

Question 19

reaction time occurs when?

Answer 19

from stimulus presentation to initiation of movement

Question 20

movement time occurs when?

Answer 20

from initiation of movement to completion of movement

Question 21

reaction time is comprised of _____________

Answer 21

premotor and motor time

Question 22

premotor time occurs when?

Answer 22

between stimulus presentation and onset of EMG

Question 23

motor time occurs when?

Answer 23

from onset of EMG to initiation of movement

Question 24

What are some factors that affect reaction time?

Answer 24

• number of choice responses
• age and pathology
• experience and practice
• task complexity
• anticipation
• stimulus-response compatibility
• attentional demands
