Brainwaves as markers of intelligence quotient and spiritual intelligence

Objective: The present study attempts to explore the role of brain waves in the expression of intelligence and spiritual intelligence. Methods and Materials: Thirty participants were assessed on different scales of intelligence and spiritual intelligence and their brainwaves were recorded via an electroencephalogram (EEG). The relative power of each electrode was then correlated with the individual raw scores on the scales. Results and Conclusions: Scores of intelligence and spiritual intelligence had significant positive correlation with relative alpha, beta, and theta waves power and significant negative correlation with relative delta waves power. Stepwise multiple regression analysis demonstrated that alpha waves are the best predictor of intelligence and spiritual intelligence, followed by theta waves. The results have been discussed in the light of available empirical researches. This study helps in broadening the applicability and significance of brainwaves in assessment and interventions related to Intelligence.
