New evidence in Human resource selection, may suggest the existence of a factor of cognitive ability termed here 'process analytic.' This new factor pertains to the ability to construct symbolic processes, identify major decision-making junctures, locating and correcting errors and faults within the process. Two studies, conducted in large-scale samples of candidates undergoing individual psychological assessment for selection purposes, provide evidence supporting the existence of the above-mentioned factor, in addition to the 'traditional' ones (verbal-logical and quantitative-performance). The implications for theoretical and psychometric developments in the field of aptitude assessment for vocational purposes is discussed as well as the need for further research to establish the preliminary direction pointed out in these studies.
