“…Not only is it unstable but it appears weak-- Shagass (1942) found it necessary to use an index (.01 X Alpha Index X Amplitude Index) which would magnify any suppression present, a procedure inclining one to believe the effect to be small. Knott (1941), after careful examination of the evidence and experiments of his own, concluded that there was only tentative evidence for conditioning. Since these early studies there have been others.…”

Conditioning of the a rhythm to a tone was attempted in 3 experiments. In 2 of these inspection of the records showed no conditioning. No conditioning was observed in 4 Ss to a kinesthetic stimulus. In a 3rd experiment 8 Ss were given 20 conditioning (CS tone) and 4 extinction trials with control on "attention." Significant suppression of a rhythm occurred, but it was small and variable between individuals. The effect seemed to be due to conditioning to the tone, temporal conditioning, and direct suppression by the tone. It seems that conditioning of the a rhythm can occur but the phenomenon is unstable and highly variable.

“…If one were to accept the first or the third hypothesis as suggestive for further investigation, one would then be able to set up a further working hypothesis accounting for any reported relationships between the variables in terms of frequency characteristics as an index to cerebral states which limit the performance of the organism. Since there seems to be some reason to believe that certain frequency characteristics of the EEG are related to the complexity of concurrent behavioral processes (8) this is at least conceivable.…”

Due to the fact that the electroencephalogram (EEG) represents one type of cortical activity, there have been repeated attempts to correlate this activity with other types, usually called 'psychological activity.' Such correlations may be attempted by one or the other of two experimental approaches: direct correlation between EEG activity and temporally simultaneous psychological activity; or, correlation between an average, and presumably constant, EEG characteristic and an average, and likewise presumably constant, psychological characteristic (9). The EEG correlates of what is called 'intelligence' may be approached by either line of attack; in the first instance, the electroencephalogram would have to be recorded during activity which could be labelled ' intelligent,' and the correlation expressed in terms of variations along two continua, one physiological, the other behavioral; in the second instance, some supposedly repeatable EEG measure, such as alpha index, or alpha frequency, or some other measure would have to be correlated with some generalized score expressive of the capacity of the individual to respond,
