In a number of earlier reports significant relationships were found between latency measures of the cortical average evoked response (AER) and measures of human intelligence. Previous studies have also shown significant relationships between various AER frequency measures and intelligence. Using data from a study in which a significant AER latency-intelligence correlation was obtained, we failed to find a correlation between AER frequency measures and intelligence. However, significant correlations were obtained between AER latency measures and certain frequency measures. The results also indicate that the frequency measures for AERs between left and right cerebral hemispheres are highly reliable.
