IQ Index using Alpha-Beta correlation of EEG power spectrum density (PSD)

Abstract

This paper presents a results of a study to investigate the relationship between Intelligence Quotient (IQ) of humans with their Electroencephalogram (EEG) Spectrum Power in term of the correlation of Beta and Alpha band power. The EEG was recorded from 50 subjects with 21 males and 29 females (mean of age = 23.16, SD = 3.8) for two tasks; closed-eyes (doing nothing in relax state) and IQ test. The results showed that 56% of the subjects have Index 2 while 6% as Index 3 with no Index 1 values. These values conclude that subjects with Alpha-Beta Index 3 and Index 2 is correlated with IQ Index 3(High IQ) and IQ Index 2 (Normal IQ) and there is no correlation between Index 1 for both Indexes.
