Notes
- Abstract:
- Electroencephalographic (EEG) measures have been used in imagery research. Several studies have reported the beneficial effects of physical practice on imagery as measured by performance outcome. However, studies have not investigated the underlying processes of imagery as individuals physically practice a skill. The purpose of this study was to determine the effects of physical practice on EEG activity when imagining a dart throwing task. EEG activity from P4, P3, O2, O1 was recorded from 30 volunteers. Participants were randomly assigned to either a physical practice condition or a non-practice condition. In the pre-test, individuals in both groups listened and followed the imagery instructions previously recorded on audio tape. After the pre-test, participants in the practice group were given fifteen physical practice throws immediately following the imagery task while participants in the non-practice group read cartoon strips for one and a half minutes (the approximate time for experimental group to perform physical practice). In the post-test, participants listened to the same imagery instructions as from the pre-test. Ten 2 second epochs were recorded and analyzed for both the pre-test and post-test. After subsequent Fast Fourier Transform (FFT) analysis of results, the absolute mean lower alpha, upper alpha, lower beta, and upper beta power was used to analyze the EEG signal. A separate 2 x 2 x 2 x 2 (hemisphere x sites x test x practice) mixed model design was conducted for each frequency band (lower alpha, upper alpha, lower beta, and upper beta). No significant main effects were found for the lower alpha activity of the participants when comparing the pre- and post-test or physical practice and no practice. However, a significant difference was determined in the site for lower alpha, upper alpha, and lower beta. In relation to practice groups no significant differences were found. The quantity of practice is a major component when evaluating possible conclusions of the results. In the current research a low complexity novel task was performed. Therefore, dart throwing should not be used to generalize the measure of learning through mental imagery.
