quiz 15 (chp. 16 new book)

Question 1

Practice variability

Answer 1

the variety of movement & context characteristics the learner experiences while practicing the skill

Question 2

Contextual interference

Answer 2

the interference that results from performing variations of a skill within the context of practice

Question 3

how does practice variability benefit future performance?

Answer 3

comparing the effects of retention of practice involving one variation of a skill with those involving several variations of the skill

Question 4

what is practice variability associated with?

Answer 4

an increased amount of performance error during practice

Question 5

how do we implement practice variability?

Answer 5

-assessment
(characteristics of the physical context, skill characteristics)
-vary practice contexts
-vary practice conditions for closed skills (intertrial variability)
-vary practice conditions for open skills

Question 6

does practice variability benefit skill learning?

Answer 6

yes

Question 7

what should be organized for practice variability?

Answer 7

the unit of instruction & practice sessions should be organized

Question 8

what is one way of solving the variable practice schedule?

Answer 8

to apply the contextual interference effect (adding activity or event that interrupts the learning process)
–this learning benefit results from performing multiple skills in a HIGH contextual interference practice schedule instead of performing the skills in a low contextual interference schedule

Question 9

what concept has research supported?

Answer 9

contextual interference effect

Question 10

does contextual interference effect apply to all motor skill learning siituations?

Answer 10

no– due to task characteristics & learner characteristics

Question 11

what are the two hypotheses that explain why contextual interference occurs?

Answer 11

1. elaboration hypothesis
2. action plan reconstruction

Question 12

two important characteristics for why contextual interference effect occurs?

Answer 12

1. higher levels of contextual interference involved greater attention demands during practice
2. people who practice according to a blocked schedule tend to overestimate how well they are learning

Question 13

which is better: variable practice or constant practice?

Answer 13

variable practice
-increases the ability for ppl to score higher on a retention test
-transfer tests
-lots of variety will help u transfer similar things

-variability n practice increases performance error in practice & the goal is to decrease error in a game situation or real life event
