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. Area I—The Hemi-Sync Concentration tape used during lec- tures and presentations had the following effect on my ability to focus on content material: Expected Distribution Distracted Me...........004+ 0... Normal Focus .....

For this reason, we could not conclude that the Concentration tape accounted for the differences in perception. Area II—The use of METAMUSIC before, during, and after group discussions had the following effect on my level of comfort and productivity: Expected Distribution More Uncomfortable ......

Concentration tape was not perceived as affecting the focus or alertness of the group. It was noted, however, that due to the nature of this tape, personal perception may not be the best way to evaluate its effectiveness. A system to evaluate an actual increase in skill or knowledge following use might be more appropriate. Even though the statistical analysis did not indicate an impact on partic- ipants’ ability to focus more intently, the facilitators believed that there may have been more impact than was perceived. The reason for this conclusion: although conditions in the workshop environ- ment were hot and humid, participants seemed well focused. Normally, this type of setting would have worn down their atten- tion span. Some distraction was noticed when Bob Monroe's voice became audible as the tape recycled on the auto-reverse equip- ment. METAMUSIC—Participants thought METAMUSIC selections, including Cloudscapes and Daybreak, had a positive effect on their levels of productivity and relaxation during small group discussion sessions and breaks. Workshop facilitators felt that the music was enjoyable for all, including the instructors. Standard stereo equip- ment (with four speakers, one in each corner of the room) was used for sound delivery. No problems occurred relative to the use of the music tapes. Exploring—Use of this tape for guided imagery and for enhanc- ing creativity in planning and problem solving was not perceived as
