Superstar athletes are often considered to exemplify peak performance. However, many athletes have an off-season where training goals become a lower priority. US Army Special Forces have no off-season, and their training goals are always a priority.
Two 12-man teams of US Army Green Berets received extensive training in EEG Alpha feedback. Before their Alpha EEG training, all 24 Green Berets had 4 channel EEG recordings of their EEG baselines under three conditions:
These baselines recorded simultaneous integrated amplitude EEG activity from 4 different cortical sites [O1, O2, C3, C4]. Each soldier had a private interview following these recordings.
All training involved simultaneous integrated amplitude feedback [auditory plus digital scores] on at least two different cortical sites [O1, O2], and were conducted at a high-security Army base using a group EEG feedback system from Biocybernaut Institute, which had been configured to train 6 soldiers at the same time.
The soldiers took batteries of personality tests before and after their Alpha training. These tests included: MMPI, Myers-Briggs Type Inventory, and the Personality Orientation Inventory [POI], which operationalizes Maslow’s concept of the self-actualizing personality. Also included in this pre-/ post-testing were the trait forms of the Multiple Affect Adjective Check List [MAACL], the Clyde Mood Scale [CMS], and the Profile of Mood States [POMS].
Many of the action-oriented soldiers had a bad experience of the meditation encampment, which they experienced as stressful. EEG baselines taken just after the encampment showed large reductions in EEG Alpha activity. In contrast, their subsequent 7-day intensive Alpha training was a very positive experience, with both 12-man teams showing large increases in Alpha activity. The Biocybernaut Institute EEG feedback equipment was available on the army base for 2 1/2 months. After their initial week of intensive Alpha training, the soldiers had continued access to the equipment for “tune-ups.” On voluntary days, when they could choose any activity they wished [swimming, playing ball, sleeping, PX], fully two-thirds chose to do additional Alpha feedback training, finding that it provided significant value to them personally and professionally.
Comparing pre-and post-Alpha training results, both 12-man teams showed significant reductions of their POMS scores of Depression/Dejection, Fatigue, Confusion/Bewilderment, Tension/Anxiety, and Anger/Hostility and significant reductions in their CMS scores of Sleepy, Unhappy, and Dizzy. The analyses of the MMPI and POI showed beneficial changes in personality dimensions that were linked to changes in the EEG Alpha activity of the soldiers. Learned increases in EEG Alpha activity produced these mission-relevant changes in personality.
Looking at before and after personality changes is not the best way to see the effects of Alpha training. Every soldier “did” the program, but not every soldier had the same amount of Alpha brain power changes. By correlating changes in brainpower with personality changes, we can connect the degree of success in brainpower changes with the amount of personality change. This connection gives us a deeper understanding than do group averages or group effects.
Correlating changes in Alpha power with personality changes also shows us how to produce the desired personality changes through specific learned changes in Alpha brain waves, thus providing a “How to do it” map or manual.
The results of this work, for the U.S. Army Special Forces [Green Berets] are given below for a number of personality dimensions:
Faking: Reductions in MMPI “F” scores were associated with increases in EEG Alpha scores. Significant correlations in the two teams ranged from -.620 to -.676 [df=9, p < .03].
Depression: Reductions in MMPI “D” scores were produced in those soldiers who substantially increased their Alpha scores. Significant correlations in the two teams ranged from -.612 to -.671 [df=10, p < .02]. The more a soldier increased his Alpha activity, the less depressed he became.
Paranoia: Reductions in MMPI “PA” scores were produced in those soldiers who substantially increased their Eyes Open Alpha scores. The significant negative correlation between Alpha changes and Paranoia changes was -.662 [df=10, p < .02]. The more a soldier increased his Eyes Open Alpha activity, the less paranoid he became.
Defensiveness: High Alpha soldiers became less defensive about acknowledging their fears and self-doubts. There were significant negative correlations between MMPI “K” scores and Alpha activity. Correlations ranged from -.625 to -.814 [df=9, p < .001].
Mania: If soldiers increased their Alpha in the brain wave training, they significantly reduced their Manic tendencies. Significant correlations ranged from -.582 to -.810 [df=9, p < .001].
Sensing vs. Intuiting: If soldiers increased their Alpha power, they shifted their Sensing vs. Intuiting in the direction of intuition. This means that through learned increases in Alpha power, the soldiers became more intuitive. Significant correlations for the two 12-man teams ranged from -.597 to -.691 [df=10, p < .02].
Inner Directed: If soldiers increased their Alpha power during brain wave training, they became more inner-directed and self-supportive. In relationship to mission objectives, they became less dependent upon the views of others, which suggests they would be more able to function autonomously in isolation and under conditions of the stress of captivity. Significant correlations for the two 12-man teams ranged from .629 to .653 [df=10, p < .03].
Self-Actualizing Values: When soldiers increased their Eyes Open Alpha during the brain wave training, they increased their Self-Actualizing Values. Significant correlations for the two 12-man teams ranged from .699 to .847 [df=10, p < .001].
Feeling Reactivity: If soldiers increased their Eyes Closed Alpha during the brain wave training, they became more highly feeling reactive. This means they became more aware of and sensitive to their own needs and feelings. This could lead to a more accurate assessment of their capabilities in crises. Significant correlations for the two 12-man teams ranged from .592 to .691 [df=10, p < .02].
Spontaneity: If soldiers had high Alpha by the end of their brain wave training, then they were significantly more likely to be high in Spontaneity at the end of the training program. Significant correlations for the two 12-man teams ranged from .582 to .592 [df=10, p < .05].
Self-Regard: If soldiers had high Alpha by the end of their brain wave training, then they were significantly more likely to be high in Self-Regard at the end of the training program. Significant correlations for the two 12-man teams ranged from .584 to .658 [df=10, p < .02].
Self-Acceptance: If the Alpha power of the soldiers went up during the brain wave training, the soldiers became more perfectionistic in their attitudes, demanding more and better performance of themselves. Significant correlations for the two 12-man teams ranged from -.614 to -.666 [df=9, p < .05].
Fatigue: If Eyes Open Alpha increased during the program, then Fatigue was significantly reduced. Significant correlations for the two 12-man teams ranged from -.665 to -.685 [df=8, p < .05]. This correlation suggests a method for the soldiers to deal with fatigue. If they have learned how to increase their Eyes Open Alpha power, they can summon up this ability when needed to overcome fatigue and thus give themselves extra energy to deal with necessary action despite what fatigue may be present.
Unhappiness: If Alpha power went up during the program, then Unhappiness went down significantly. Significant correlations for the two 12-man teams ranged from -.595 to -.744 [df=7, p < .03]. All of our previous research has shown that increasing Alpha power increases happiness and effectiveness and reduces UN-happiness. It is thus entirely consistent to find this result in soldiers who have learned to increase their Alpha brainpower.
The previous paragraphs are summarized here and sorted according to statistical certainty (best first). The sense of all the correlations has been made positive, and the direction of the dimension reversed as necessary. For the Measure: Alpha = increased Alpha brain waves; EOpenA = increased Eyes Open Alpha; EClosedA = increased Eyes Closed Alpha

It is beyond the scope of this report to detail all of the significant correlations involving changes in the personality of the soldiers as they relate to changes in Left/Right Alpha brain wave power. However, it may be useful to list some of the personality traits which can be changed by the appropriate learned changes in the Left/Right Alpha power ratios:
