Multivariate Models of Cognition and Personality: The Need for Both Process and Structure in Psychological Theory and Measurement1

This paper calls for the development of sequential models of cognition and personality as a way of adding process to the primarily structural concerns of current multivariate models. At the same time, it points to the results of factor analysis, particularly as summarized in a hierarchical extension of Guilford's structure‐of‐intellect system, as a source of component variables for such sequential formulations. The need to take into account personality, developmental, and environmental variables in these sequential models is also emphasized.
