|Transparent's research director Tina
L. Huang, Ph.D., working in conjunction with
psychology professor Christine Charyton, has
conducted a meta-study
comprehensive review and analysis of the psychological effects
in brain entrainment research".
The study is a critical overview of the field, and the research done to date. It compiles a comprehensive review of the literature from peer reviewed journals on the psychological effects in brainwave entrainment research. 21 experimental and quasi-experimental studies were analyzed, spanning outcomes of enhanced attention, memory, overall improvement in intelligence and reading ability, relief of stress and anxiety, mood enhancement, relief of pain, migraines and pre-menstrual syndrome (PMS).
Only peer-reviewed studies were analyzed. Case studies were excluded. Preliminary statistical analysis suggests that brainwave entrainment has positive effects on relieving psychological symptoms. 8 studies examined short term single session effects, 8 examined longer term multiple session effects and 2 examined both. All published studies reported at least one positive outcome using either auditory (4) or photic stimulation (12), and/or audio visual entrainment (AVE) (5), within frequencies hypothesized to have positive effects.
The study also goes on to form recommendations about future research and improvements in current methodologies.
Dr. Huang will be presenting her findings at the 16th annual Winter Brain conference on Sunday, January 21 in Palm Springs, CA .
Dr. Huang is a Neuroscientist from Somerville, Massachusetts. Prior to joining Transparent, Tina worked and studied in the field of Neuroscience for nearly 10 years. She holds a doctorate in Neuroscience from the University of Rochester and has also completed 2 post doctoral fellowships in Neuroepidemiology, the first at the Johns Hopkins Bloomberg School of Public Health, and the second at the Human Nutrition Research Center (HNRCA) on Aging in Boston.
