Abstract:
Rapid-speed photographs taken early, midway, and late in a series of 80 trials of a closed skill (backward jump for distance) were analyzed to determine the effect of practice on within-S variability in performance technique. Means and variability for the distance criterion remained constant over sessions while variability at angle of hip and ankle during landing and variability of joint velocities prior to take-off decreased. Differences between kinds of closed skills were considered in accounting for the outcome.

Steps in the Modeling Process
Attention is the first necessary component for observational learning. It involves focusing on what the model is doing and saying. For example, if you decide to take a drawing class to enhance your skills, you need to pay close attention to the instructor's words and hand movements. The characteristics of the model significantly...
