An Empirical Investigation Into the Effect of
Beta Frequency Binaural-beat Audio Signals on Four Measures of Human Memory

Abstract

Beta frequency binaural-beat audio signals were utilized to investigate facilitation of human performance on two memory tasks and two memory related tasks. Subjects were 50 college students randomly assigned with a double-blind methodology to the control or experimental groups. The control group listened to instrumental music. The experimental group listened to the same music with binaural-beat audio signals bedded under the music.

The four dependent variables used were a 25 item word list recall test, a 25 item word list recall/recognition test, and from the WAIS-R the digit symbol and digit span subtests. The experimental group displayed statistically significant (p>.05) increases in mean scores with the word list recall test, the digit symbol subtest, and the digit span subtest.

No statistically significant increases in the experimental mean over the control mean were noted in the word list recognition/recall subtest. The results indicate that beta frequency binaural-beat audio signals are an effective method for facilitating simple free recall memory, ability to attend, and the ability to persevere at routine motor tasks.

Preface

This thesis is the culmination of a long personal struggle with the educational system. I have always loved questioning and learning. Yet before graduate school I never enjoyed, or did well in school. I have spent a lifetime on the edge of academic failure where every mediocre grade was a struggle. As a child, adults told me that I was smart and that there was no reason I shouldn't be able to make excellent grades. The unspoken judgement being that I just didn't want to, that there was something wrong with me or worse, that I just didn't try hard enough. I know I frustrated many people, yet I was the most frustrated one of all.

As an adult I worked my way through college, and graduated out of luck and shear persistence. If I failed a class, I took it over until I made the grade I needed. In graduate school I knew I would need a new strategy, since I could no longer take classes over with the new grade replacing the old. I could not afford to work so hard for such mediocre results. I was still very frustrated, and I turned that frustration into a search for answers.

To my joy, I found a combination of dimethylaminoethanol (DMAE), a nutrient found in seafood, and binaural-beat signals worked well to offset my learning disabilities. What had been an academic Sisyphean struggle became a genuine pleasure. The effect was one of personal transformation and excellent grades. I felt as though I had been set free from a life long prison.

The thesis you now hold arises out of my personal success with, and interest in, binaural-beat signals. This thesis is dedicated to Elisabeth Schumacher, my mother. Without her unfailing love and devotion, none of my life achievements would have been possible. She has believed in me when I didn't believe in myself. She has given me support when I needed it, without regard for herself. She has loved me beyond all reason, and that has sustained me down a long and rocky road.
