Preliminary work with the Biolight bio-driven AVS (audio-visual stimulation) convinced us that in a single session, peak
alpha frequency and the hi/lo alpha band magnitude ratio (11-13)/(7-9) could be at least temporarily increased. Prior research by other investigators had shown that brighter
students appeared to have faster peak alpha frequencies and higher alpha ratios. Giannitrapani’s research in particular showed a positive correlation between IQ and narrow band 13 Hz power. We then attempted to use this technique over an extended period with university students who had sought help from the
Counseling Center because of difficulties they were having in school. The Biolight device was used by the students for a period of 15 minutes each day.
Pre-post PSPs (Psychophysiological Stress Profiles were performed along with the IVA continuous performance
test,
certain IQ subtests and the POMS at each session. Grade point averages (GPAs) were collected for three
quarters: Fall ’97 (pre), Winter ’98 (during) and Spring ’98 (post). Training consisted of 30 15 minute sessions, approximately 5 per week. A control group received the usual counseling help but no Biolight use. Eight subjects in each group completed the study and allowed their GPAs to be given to us for the 3 quarters. A t-test revealed a p = 0.004 for the test of pre-post differences in GPA between the experimentals and controls. Certain EEG parameters showed significant changes as predicted.
