Investigating the Effectiveness of Personalized Optimal Gamma Auditory Frequency Stimulation Intervention on Cognitive Function Enhancement
This study tests whether listening to gamma-frequency sounds tuned to each person's own brain rhythm improves thinking skills and brain synchronization more than a generic, non-optimal frequency. Twenty healthy adults try both versions for one month each. Researchers measure brain activity with EEG and executive function tasks. It is a small device study with no phase label, so early-stage.
You may qualify if
- Age between 18 to 40 years old.
- The Cognitive Abilities Screening Instrument (CASI) score is within normal ranges adjusted for age and education.
- Participants have no history of severe neurological or psychiatric disorders (such as stroke, epilepsy, depression, migraine, etc.) that could affect cognitive function.
- Participants have not used drugs that may affect cognitive function (e.g., benzodiazepines, anticholinergic medications, etc.).
- Participants with normal or corrected vision (e.g., glasses or contact lenses) to normal levels.
- Auditory stimuli induce significant neural entrainment.
- Self-reported normal hearing
You're excluded if
- Participants enrolled in any cognitive enhancement study within the past two months.
- Participants with a history of disease that could affect cognitive function (e.g., cancer, autoimmune diseases, etc.).
- Individuals with tinnitus or hyperacusis
