Can Photic-Stimulation and EDR Feedback improve Academic Performance?
Hypothesis 1, that the E group would show significantly greater pre-post GPA differences than the controls at the end of the pre-training quarter and at the end of the quarter following training was supported. Figure 3 shows the mean difference and standard error of the mean in the Fall 97 and the Spring 98 GPAs for both groups. This graph represents the most important result of this experiment, i.e., the GPA comparison for the quarter prior to and following the training. During the spring 98 quarter the E group did not receive any training. However, this trained group was able to maintain its higher level of academic performance even though training had been completed in the preceding quarter. (Note: The Ns for the E and C groups may vary from figure to figure because of missing data (one subject did not report her GPA), or, in the case of physiological data, because of deletions due to artifacts. All artifacting was done from the original Excel sheets of 10 second data before any ave
