Unformatted text preview: of KR konw hte difference between KR-delay and post KR!!!!! Between any two performance trials, two intervals of time
are created: KR-delay interval: time between end of trial
and provision of KR
Post-KR interval: time from end of KR to start
of the next trial
R1 KR-delay KR1 R2 Post-KR delay Inter-response interval Length of KR-delay delayed KR always stayed higher-- than with feed back right away. The assumption that KR should be provided immediately
is not upheld in research
But – there is a minimum delay that must occur
• Lever movement to match
• Instantaneous feedback
resulted in poorer
performance than delayed
feedback (3.2 s)
Swinnen et al. (1990) Why? 5 7/4/12 Activity during the KR-delay not resposible for this slide Does activity during the delay between end of
performance and delivery of feedback affect learning?
• Negative effect if learner focuses on other s performance
or learns secondary task
• Linear positioning task
• Unfilled KR-delay = rest
• Filled KR delay = other
• Graph shows interference
Shea & Upton (1976) Activity during the KR-delay Positive effect if person engages in….
• subjective performance evaluation strategy
Hogan & Yanowitz (1997) • estimation of specific characteristics of
movement related components of action
Liu & Wrisberg (1997) Why? Length of post-KR interval
An important period of time as:
Learners develop plan of action for next trial- promotes
problem solving (important in transfer) Evidence suggests a minimum time again (~1 secon...
