Motor Control Chapter 12, Part 2

Motor Control: Various Issues Human Learning & Performance Iver Iversen Fall, 2003

Typical Motor Learning Experiment Acquisition: Some form of KR manipulation is applied to a skill (different

levels of KR for different groups of subjects) Transfer Test: Determine the effects of the previous exposure to KR. The Transfer test has a constant level of KR (usually

NO KR) for all groups of subjects Learning versus Performance Performance: Immediate or temporary

effect of KR during training seen when behavior improves during Acquisition with some form of KR Learning: Relatively permanent effect (of training) seen when behavior can be

sustained without KR after training is completed Calculating Distance The next slide shows how to calculate the

distance between two points in a coordinate system It is based on the Pythagorean Theorem You dont need to know this, but you might

be interested in how it is done Images

The following slide shows a blown up version of

the an individual session to better highlight the various feature of the display. The next three slides show all the data for 3 subjects. For all subjects, Variable Error clearly increases

when the distracters are introduced in Session 6 Some subjects show clear examples of Constant Error (a consistent bias in one direction from session to session)
