Just as the Raven Progressive Matrices Test was uncorrelated in this sample with other measures of intelligence so was it much less well predicted from several information processing measures. It was found that verbal performance, indicated by a vocabulary score, was highly predictable from measures of information processing. While preserving order information was significant, it was the ability to overcome linguistic convention, in a right to left conversion task, that was the major determiner of verbal scores. Correlates of the Wechsler Adult Intelligence Scale (WAIS) verbal scores, partially dependent upon a vocabulary test, were essentially the same as those for the vocabulary measure itself. IQ's derived from the nonverbal subtests of the WAIS were well predicted by a pair of information processing measures that tap ability to maintain the order of input of nonverbal stimuli, either auditory or visual. Although Raven scores were not correlated with WAIS performance IQ's, these same two indices of accuracy of judgment on the temporal order of nonverbal stimuli also contributed to the prediction of the time required to solve Raven problems. Finally, there is the suggestion that verbal problem solving proficiency may be grounded in an ability to accurately maintain the order of speech elements. The two findings that at least some measures of nonverbal intelligence are linked to accuracy in recovering the order of nonverbal stimuli and that verbal problem solving efficiency is linked to accuracy in recovering the order of verbal stimuli, represent this study's contribution to the further development of relationships between psychometrically evaluated abilities and measures of information processing efficiency.
