Week 11

Question 1

Abilities

Answer 1

-stable traits that underlie/support persons skill

Question 2

Prediction of motor ability

Answer 2

-one study found that bimanual coordination and reaction time predicted transfer performance
-found that individual differences in perceptual motor ability may predict learning

Question 3

Motor aptitude test

Answer 3

-to determine how individuals will respond to practice

Question 4

3 main areas of concern for people looking to take on individual differences research

Answer 4

-differences in initial performance
-differences in the rate of skill acquisition
-differences in maximum skill levels

Question 5

Types of transfer

Answer 5

-positive
-negative

Question 6

Positive transfer

Answer 6

-experience helps the learner perform the new skill

Question 7

Negative transfer

Answer 7

-experience ay hamper the performance of the new skill (driving on opposite side of the road than usual)

Question 8

Pre-post design

Answer 8

-performance prior to acquisition is compared to performance in retention and transfer
-uses a difference score

Question 9

Low difference score

Answer 9

-less improvement

Question 10

High difference score

Answer 10

-more improvement

Question 11

Difference score

Answer 11

=RMSEpost - RMSEpre

Question 12

Three phase theory

Answer 12

-3 phases that affect learning

Question 13

Phase 1

Answer 13

-initial learning stage
-strong attentional and cognitive demands

Question 14

Phase 2

Answer 14

-integration and consolidation
-perceptual speed and comparison and contrast abilities

Question 15

Phase 3

Answer 15

-skilled performance becomes more proceduralized
-more movement fluidity is achieved and attentional demands are reduced

Question 16

Support for deliberate practice

Answer 16

-although there are differences in improvements, everyone gets better
-invest in everyone
-greater pool of players elicits a higher chance of generating an environment that promotes motor skill acquisition

Question 17

Sound induced flash illusion

Answer 17

-people are more accurate at predicting blinks when there is corresponding beeps
-blinks with beeps that do not match will make people think there is more blinks than there actually is

Question 18

Psychometric curve

Answer 18

-stimulus intensity at threshold is the intensity at 50%

Question 19

Signal detection theory

Answer 19

-we can model probability distributions as signal and noise

Question 20

Stimulus criterion

Answer 20

-if the perceived intensity is greater than the criterion stimulus is detected
-if perceived intensity is less than criterion stimulus is not detected

Question 21

Possible stimulus identification outcomes

Answer 21

-hit
-false alarm
-correct rejections
-miss

Question 22

Hit

Answer 22

-stimulus was presented and individual detected it

Question 23

False alarm

Answer 23

-stimulus was detected when there was no stimulus

Question 24

Correct rejection

Answer 24

-there was no stimulus and no stimulus was detected

Question 25

Miss

Answer 25

-there was no stimulus but a stimulus was detected

Question 26

More liberal criteria

Answer 26

-more hits than correct rejections

Question 27

More conservative criteria

Answer 27

-more correct rejections than hits

Question 28

Calculating d'

Answer 28

-d' = Z (for the number of hits) - Z (for the number of FA)

Question 29

AV thresholds and perceptual binding

Answer 29

-investigated individuals differences of perception in mcgurk stimulus could be related to variability in temporal binding window

Question 30

Visual cortex activation

Answer 30

-high performers showed more during drawing than low performers
