An appraisal of biological theories of intelligence: A reconsideration of Eysenck’s theory of intelligence Available to Purchase

This study is a sequel of a paper by Fidelman in 1996, where it was argued that the idea of Hendrickson and Hendrickson in 1982, that high intelligence is related to a small probability of neural transmission‐errors, may be correct, in spite of the contradictory evidence. The relation between several biological theories of intelligence is discussed in this study. These theories are Haier’s and Schafer’s theories relating intelligence to the energy consumption of the brain, the Hendrickson paradigm, Eysenck’s extension of the Hendrickson paradigm according to which a neural message is sent repeatedly until it is received identically a certain number of times, Jensen’s theory relating intelligence to reaction‐time, and Haier’s theory of synaptic density. Discusses the proposition that the attentional theory of Bates and Eysenck may be considered as an extension of the paradigm of Schafer.
