    Auditory evoked potentials and digit span in children [Abstract]
    Clark, Graeme M. ; Knight, Lyall J. ; Stanley, Gordon V. ( 1974)
    Recent studies have shown a relationship between visual evoked potentials and intelligence (1,2). It is of interest to determine if auditory evoked potentials can also be used in assessing aspects of intelligence. Correlations between auditory digit span and various components of the auditory evoked potential were examined as digit span has been shown to be important component of level of intelligence (3) and other communication skills (4). Eleven normal children (7 boys and 4 girls), between the ages of 9 and 12 years, volunteered for this study. Digit spans were obtained on a separate testing occasion from the evoked potentials. The measure of digit span was that developed for the Illinois Test of Psycholinguistic Abilities (4) and represents a more reliable measure than others commonly used.

    Auditory evoked potentials and auditory sequential memory [Abstract]
    Clark, Graeme M. ; Knight, Lyall J. ; Stanley, Gordon V. ( 1974)
    The evaluation of intelligence in infants and young children is important in assessing their prognosis and institutional placement, and is difficult with present clinical methods. Therefore, the recent studies which show a correlation between visual evoked responses and intelligence are of value. It is also of importance to determine if auditory evoked potentials may be used in assessing children with communication disorders, as their defect frequently involves the auditory system, and they will often require evoked response audiometry to exclude loss of hearing from the diagnosis.

    The effects of muscle relaxants on auditory evoked potentials in humans
    Rickards, Field W. ; Clark, Graeme M. ; McMahon, Don S. ; Dewhurst, David J. (Cambridge University Press, 1973)
    In studies on auditory sensory information processing it is frequently assumed that the average evoked potentials from the scalp are produced by neural generators in the cortex. This may not be the case as there is evidence to suggest that at least one component of the auditory evoked response may be myogenic (Bickford et al., 1964). Therefore, the present study was undertaken to help determine the extent to which auditory evoked responses are myogenic or neurogenic.
