To make participants as comfortable as possible with this new ii --- PAGE 3 (OCR) --- Fall 1993 experience, everything on the tape—including the wording and the rationale for each side of the tape—was explained. Each person had been asked to bring a Walkman™-type stereo player to the workshop. Tape use was a scheduled part of the activities. On the first day, participants listened to Prep before lunch. They agreed to listen to it again that evening. Prep was also used be- fore lunch and on the evening of the second day. At lunchtime on the third day, participants heard the Relax side of the tape for the first time. They were then encouraged to begin using the code (Function Command] whenever they wanted to bring about per- sonal relaxation. ... H-Plus Relax was perceived by participants to have an impact on their state of relaxation. Participant Perceptions of Hemi-Sync It was decided to evaluate the Hemi-Sync technology through the perceptions of the participants. Each person was asked to com- plete a personal perception form, giving his or her reactions to each of the Hemi-Sync applications. Thirteen of the fifteen partici- pants completed the form. Two had to leave the workshop early because of unexpected business problems. Statistical Analysis To derive maximum usefulness from the perception evaluation, a statistical analysis was performed. Anytime an opinion is asked, a perception is recorded, or a measurement is made, some differ-

ences will occur on the basis of “chance” only. A statistical analysis uses mathematical formulas to determine if the differences in response are most likely related to chance or if they are most likely “real,” and therefore more useful in drawing conclusions about the project or experiment. In this case, the Kolmogorov-Smirnov statistical test was select- ed as particularly appropriate for examining the difference between how a group would normally be expected to respond and how they actually respond. Each area of the perception form was examined.
