Task Intrinsic Feedback- Sensory Feedback
Information obtained from senses. Another name for sensory feedback is intrensic feedback. This is information obtained from within the body. The older we get the MORE dependent we get on visual feedback. 2

Task Intrinsic Feedback- Augmented Feedback
"Extrensic Feedback"
KR- Type of augmented feedback that provides info about the movement or performance outcome KP- " feedback that provides info about the movement characteristic that lead to the movement or performance outcome KNOW DIFFERENCE

3
Role of Augmented Feedback (4)
Error info- So they can correct the next movement
Reinforcement- Increase probability of the movement occuring agian Motivation- positive feedback to do good
Dependence- Rely on feedback
4
Frequency of KR (2)
Absolute- KR that represents the ACTUAL # of trials for which KR was provided without consideration for the total # of trials Relative- KR that represents the percentage of total # of trials that KR was provided 5

Formula for Relative Frequency of KR
      # of Feedback Presentations
RF=              Total Trials                  x 100

100% feedback is the traditional viewpoint.
6
Winstein & Schmidt- 1990
KR groups: 100%, 33%
100%- KR after each trial -
33%- KR 1/3 of the time
AP- 100%  RT- 33%
7
Hypotheses to Explain KR-
Guidance Hypothesis
Predicts if KR is provided too frequently, participants will become DEPENDENT on the guiding properties of KR & perform poorly on a no- KR RT. KR group: 100%, 50%, 0%
100%- perform worst, predicted
8
Hypotheses to Explain KR-
Specificity Hypothesis
Predicts participants will perform best on a retention test when practice occurs in an AP environment that is simular to the RT. 0%- performs best, predicts
9
Timing of Augmented Feedback (2)
Concurrent- Augmented feedback that is provided while a person is performing a skill. Provided during a movement Terminal- Feedback that is provided after a person has completed a skill. Privided after a movement 10

Behrman, Vander Linden & Cauraugh- 1992
KR group: Concurrent- 100% (feedback during & after) , 100%, 50%,

AP- Concurrent-100%    RT- 50%

*Results support guidance hypothesis*
11
Vander Linden Cauraugh & Greene- 1993
(RT without KR)
KR group: Concurrent-100%, 100%, 50%

AP- Concurrent-100%    RT- 50%
12
Park, Shea & Wright- 2000
KR group: 0%C- 100%T (=100%), 50%C-100%T, 100%C-100%T (=Concurrent- 100%)

AP- Concurrent-100%      RT- 50%C- 100%T
13
Summary of Concurrent & Terminal Augmented Feedback-
(Task Intrinsic & Sensory) (2)
Concurrent Feedback improves performance in AP when the feedback is available. When concurrent feedback is removede on RT & TT, there tends to be a negative learning effect.

14
Summary of Concurrent & Terminal Augmented Feedback cont-
(Task Intrinsic & Sensory) (1)
When the information calue of task-intrinsic feedback is low, but the information calue of augmented feedback is high, concurrent augmented feedback will most likely lead to a dependency on the augmented feedback. 15

Percision of KR (1)
Qualitative KR- Provides information on DIRECTION of error. Discriptive in nature & indicates the quality of performance

16
Percision of KR cont. (1)
Quantitative KR- Provides information on direction of error & the magnatude of error. Precise in nature and indicates the quantity of performance. It includes a numerical value. Numerical calue represents the magnatude of error ex15 yds to right 17

Magill & Wood- 1986
KR group: Qualitative, Quantitative

AP- Qualitative early in AP, Quantitative in late AP.    RT- Quantitative 18
Summary of Qual & Quant KR
More general information about learners performance is more desireable in early stages of learning Novice performers should receive less precise KR than intermediate performers As precision of KR increases so should time provided to process info 19
