In their seminal study of chess expertise, Simon and Chase (Chase & Simon, 1973; Simon & Chase, 1973) proposed that perceptual learning was a necessary component of skill acquisition. In their view, acquisition of skill results from the strategic use of learning at multiple levels to adaptively overcome inherent limitations. The knowledge…

Use of a retention test in an investigation regarding the post-knowledge of results (KR) interval provides evidence suggesting that, while activity during the post-KR interval is detrimental to performance, no such assumption can be made about its effect on learning. Implications for motor learning and performance are discussed. (Author/PP)

Researchers studied the effect of interpolating extraneous information on students' ability to process cognitive information concerning their prior performances on the McCloy block test. The extraneous information was given in the interval between their last test and their next attempt to perform it. Results are discussed. (Author/PP)

Aspects of information feedback and practice conditions were studied to gain insight into processes underlying the observational learning of motor skills. A major purpose was to test whether subjects observing a practice variability strategy would perform better than those observing a model practicing under constant conditions. (Authors/PP)

The effects of practice on the bilateral transfer of complex dance movement patterns were studied by having subjects learn two sequences under eight different conditions. Results indicate that teachers have been correct in expecting students to transfer movements bilaterally (from one side to the other) but should teach to the nonpreferred side.…
