We will determine the impact of this variable on motor performance and motor learning. Some feel that its only impact is during performance, where frequent rests help to improve performance. Others, however, feel that frequent rests also improve learning, as measured after all temporary benefits are assumed to have dissipated. The relevance of this lab to practice situations is very direct, since decisions about whether or not to distribute or concentrate practice (include rest intervals or not) are made in virtually every motor skill practice situation. Task and Equipment Needed The task is to learn to print capital letters which are rotated 180 degrees. For example, imagine the capital letter " A " with a pin placed in the center, and rotated 180 degrees so that it is now upside down (e.g., ). Materials needed : pencil and lined paper Procedures Organize the lab participants into two groups. One group will practice according to a massed practice schedule (no rest between trials), and the other group will practice according to a distributed practice schedule (with equal practice and rest intervals). For both groups, a trial involves 30 sec of continuous rotated letter printing. Both groups will have the same number of practice trials. The lab instructor will time consecutive 30 second intervals. Beginning at the first trial, start with the letter "A" and continue to go as far as possible through the alphabet during the 30 sec (two lines are available per trial). Begin each new trial on a new line with the letter after the one you finished with on the previous trial. The lab instructor will cue the end of each 30 sec trial. You are to cover the previous trial with a sheet of paper so as not to see previously drawn letters....
