We report results of a magnetic ressonance imaging (MRI) study of 146 Brazilian children, whose intelligence quotient scored less than 70. 50% of MRI examinations did not exhibit any signal of structural lesion (N group), whereas a focal thinning at the junction of the body and splenium of the corpus callosum; ventricular asymmetry; periventricular leukomalacia; gliosis and arachnoid cysts were among the most frequent findings in the remaining of subjects (L group). Maternal stress and altered blood pre ss u re were the most frequent findings in the pre-natal history of both N and L children. Familial antecedents of mental …

Confirmation Of The Structural Dimensionality Of The Stanford-Binet Intelligence Scale (Fourth Edition), Gregory J. Boyle
Gregory J. Boyle
The new Stanford-Binet Intelligence Scale (fourth edition) seemingly represents an important advance in design and construction over the earlier form L-M. The latest version of the instrument (SB-IV) is purported to index both crystallized intelligence (Verbal and Quantitative Reasoning Areas) and fluid intelligence (Abstract/Visual Reasoning Area) structural dimensions respectively. Given the prominence of modem information processing theories of cognition, a separate Short-Term Memory (STM) Area is also provided. The authors provided confirmatory factor analytic (CFA) evidence to support their claim for the construct validity of each of the four cognitive ability areas. However, several inconsistent factor loadings were apparent, for …
