Abstract

Recently, Dodrill (1999) revised a previously described "Myth of neuropsychology'' (1997) to state: "Just as below average performances on neuropsychological tests are found when intelligence is below average, to that same degree above average performances on neuropsychological tests are expected when intellectual abilities are above average. '' This study addresses the relationship between intellectual and neuropsychological performance in the context of Magnetic Resonance Spectroscopy (MRS) measurements of the neurometabolite N-acetylaspartate (NAA). When subjects were stratified by Full Scale IQ (Average, High Average, Superior) they differed significantly in terms of total neuropsychological performance [F(2,47 = 17.63; p <.001] and theneuronal marker NAA [F( 2,47) = 3.25; p <.05]. Regression analysis across groups demonstrated that FSIQ and NAA were independently related to Total z-score [F(1,47) = 29.43; p <.0001] and accounted for over half the variance(r(2) of model =.56). The concurrent relationship of FSIQ and NAA to totalneuropsychological performance suggests that the relationship between measures sensitive to intellectual ability and neuropsychological performance is real, and does not reflect arbitrary psychometric or scaling properties of the WAIS-III.
