Detailed analysis of the reactions to training and of the verbal regulation of behavior scores of subjects from a remote Indian reserve showed that the low IQ of this group resulted from an underdevelopment of reflective verbal thought, but not from a biologically determined inadequacy. (Authors)

Two experiments examined whether correlations between IQ and probed serial running memory depend on IQ-related individual differences in the retention of order information in short-term memory. Children's IQ correlated with memory, regardless of whether instructions emphasized serial or free recall; and with recent item but not recent order…

Intelligence and short-term memory correlations in children were measured using probed serial recall of supraspan digit lists. Results showed the predictive power of intelligence to range from a maximum in the case of recall for recency items to practically zero in the case of primacy items. (Author/MV)

Children, below- and above-average intelligence, were administered tasks involving matching information between auditory/visual modalities and temporal/spatial presentations. The below-average group made more errors and matching problems were not particular to one modality. Factor analyses did suggest that matching processes varied with level of…
