ch. 10 Flashcards
experiments that show all knowledge isn’t necessary
-Polani: bicycle balance
-Wulf + Weigelt: complex slalom/ski-simulator tasks
experiments that show some knowledge is helpful
-Judd: throwing darts to targets underwater
-Hendrickson + Shroeder: shooting air gun underwater
Bell + Hardy
evaluated golfers focused on ball trajectory, landing point, or club
-study found landing point was most significant impact on accuracy
Porter
looked at distance jumped in long jump
-study found that athletes performed better when they paid attention to further away target
Banks
looked at kayakers + evaluated race time when focusing on finish line or paddle
-study found that focusing further away (finish line) was better
Wulf + Weigelt
complex slalom/ski-simulator tasks
-goal was to make oscillatory movements with force against the platform
-1 group was given efficient pattern information ahead of time; other group got no advance information + had to do trial/error on their own
-group with advance information performed less effectively due to TMI
Wulf, Chivacowsky, Lewthwaite
age-based study where older adults learned a novel/challenging balance task
-enhanced expectancy group was told people perform well on the task, which made the task appear less daunting
Hird
compared mental vs physical practice using pegboard, pursuit rotor task, + control group with unrelated task on stabilometer
-pre-test, post-test set up
Armstrong
3 day practice with transfer test on 3rd day when no augmented information was provided to subjects
-groups were terminal knowledge of performance (at end), concurrent knowledge of performance (during), + guidance
-study showed that guidance won’t do subjects well in transfer/learning because they won’t be able to perform without the device
which knowledge of power is best
TERMINAL
Badly + Longman
massed vs distributed practice for training postal workers using a keyboard under different practice distribution schedules
-study found shorter rest periods degrade performance + longer rest periods result in better performance
McKay + Wolf
looked at dart throwing accuracy with subjects focusing on either the bullseye or dart trajectory
-study found looking further away (bullseye) was better
distributing
longer rest periods
massing
shorter rest periods
shorter/longer rest periods degrade performance
shorter
-longer rest periods result in better performance
