“…Reports issuing from other laboratories, however, have generally not confirmed Berger's and Kreezer's findings of relationships between alpha index and mental defective intelligence. Rahm and Williams (1938) reported an absence of significant relationships between occipital alpha index and MA in a group of unselected feebleminded adults ranging from 1 to 9.8 years MA. Their results may be attributed to the heterogeneous nature of their sample in regard to kind and degree of mental deficiency, age, sex, etc.…”

Literature on the relationship of EEG to test intelligence scores is reviewed. Evidence for the relationship between these 2 variables seerns strongest for samples of children, institutionalized geriatric patients, mental deficients, and brain-injured persons; and weakest for samples of normal adults. EEG indices seem to be more strongly related to MA than to IQ. Criticisms of the previous research are directed at insufficient attention to the measurement of intelligence, failure to control for sex, too restricted placements of leads, too restricted an employment of EEG indices, and the assessment of EEG performance under inappropriate conditions. These methodological and theoretical problems are discussed and some solutions proposed.

“…Normal control groups have been employed when appropriate in all studies of EEG and intelligence except one (Rahm & Williams, 1938), in which the brain electrical activity of the patients was judged against general standards of abnormality. In several studies, the control groups were somewhat less than adequate in terms of numbers and/or ages of the subjects.…”

“…The series of studies by Kreezer and Smith (Kreezer, 1936, 1937, 1938, 1939, 1940Kreezer & Smith, 1937, 1950 can be discussed as a group since the procedure was apparently the same in all and the data reported in the various papers overlap to some extent. The data were all collected prior to 1940 (the 1950 article, which Vogel and Broverman apparently considered a later replication, was actually based on data collected in 1936).…”

“…These provide no more convincing negative evidence than the above studies do positive evidence. The study of Rahm and Williams (1938) suffers from a number of the same methodological deficiencies as several other early studies. Corriol and Cain's (1949) study involved 36 5-15-year-old heterogeneous boys with character disorders, of whom 16 were retarded.…”

“…The experimental group of Rahm and Williams (169) was made up of 36 unselected mentally deficient individuals ranging in mental age from under 1 year to 9.8 years. Since the group contained only two Mongols, it seems likely that it is to be regarded as more closely comparable with the nondifferentiated familial group considered above than to either the Mongolian or phenyl pyruvic group.…”

I. THE BODILY FUNCTIONS THAT ARE IMPORTANT DETERMINERS OF INTELLIGENT BEHAVIOR: INTRODUCTIONThis chapter of the Yearbook, dealing with the bodily basis or correlates of intelligence, necessarily differs somewhat in scope from the preceding chapters. It is impossible to give, even in summary form, all the relevant evidence, which could be collected from a great variety of sources, that bears directly or indirectly upon the problem of the relationships of the make-up of the human organism and the correlated intelligence of the human individual. Among the various technical fields of knowledge in which information on this subject is to be found are anatomy, physiology, pathology, embryology, histology, anthropology, neurology, surgery, comparative psychology, and a dozen more subdivisions of these special fields. Keeping in view, therefore, the general purpose of this Yearbook, it seems best, in this chapter, first, to try to make clear the assumptions underlying the evidence that what we call ' intelligence ' is indeed grounded in the activity of the living organism, and second, to give some indication to the reader of the possibility of further study in this field, which is at once too technical and too extensive for full consideration here. Many of the bibliographical references given will be of especial value to the reader who wishes to go further into this subject and many of these books and articles themselves contain large lists of references.
