Mirror Hand Tracing Experiment, Introduction

Introduction:
The phenomenon of practice effects has been addressed in this study which sought to determine if practicing a mirror-tracing test before and after some practice using the opposite hand would yield a significantly different performance. In general, as a person becomes more exposed to a task, their performance at that task will improve. Theory holds that later attempts at this task will require less time for completion, and yield fewer mistakes than previous tries. To be analyzed in the outcome of this experiment is the learning curve produced in assessing the transferability of practice effects from one hand to the other, namely the number of errors a subject makes in his/her tracing tests, and the time it takes s/he to complete the test. I expected the second go-round of non-dominant hand testing would reveal no practice effects and, therefore, no statistically significant difference in performance.
