This paper presents the study of a seven-member family, six of whom showed significant EEG abnormalities. An attempt was made to correlate these data with other clinical information gathered, using the standard MMPI and standard psychological tests which were rated under "blind" techniques. The method of psychological testing and rating used in this study would appear to be quite useful in studying a family or small group as it revealed the most significant data, differentiating clearly those members with EEG abnormalities from the member with a normal EEG. None of the methods employed was able to accurately differentiate the four members with 14 and 6/second positive spiking from the two members with other types of EEG abnormalities.
