EEG Correlates of Verbal and Perceptual Reasoning

Abstract

Identifying the neural underpinnings of intelligence is one of the major goals of modern intelligence research. However, few imaging studies explore the high extremes of intelligence, and most use only a single composite IQ score. This study used quantitative EEG recordings to investigate correlations between the EEG variables of individual alpha peak frequency, relative power, and coherence, and scores on verbal and perceptual reasoning tests in participants with IQs from the low-average to exceptionally gifted ranges. Overall, the results did not reveal any pattern of significant relationships between these EEG measures and the two psychometric tests. Since this study had only a small sample, heavily skewed towards the high-IQ end of the scale, no definitive conclusions about the EEG measures and verbal and perceptual reasoning can be drawn. Nevertheless, it reveals many opportunities for further research, and suggestions are made for progressing this topic in the future.
