Abstract
Publisher Summary This chapter discusses the relationship of task performance to the variables of chronological age (CA), mental age, and intelligence quotient (IQ). The chapter discusses a specific critique of Harter's analysis and the sources of problems that have been encountered to attribute performance changes to the differences in CA, MA, or IQ. It also discusses the proposal that the studies of the so-called effects of CA, MA, and IQ should be planned as multi group studies that will permit an extended mapping and analysis of the three-dimensional surface that represents the regression of task performance on CA, MA, and IQ. Methodological questions are discussed as each becomes important either for an understanding of the limitations of the original analysis or for the development of the new analysis. The chapter also discusses an assessment of the new procedures and with the implications of the present analysis both for (a) the interpretation of the role of CA and MA in performance and (b) the design of future experiments. It also discusses proposed graphic procedures for analyzing data in response surface form and for evaluating the ruled surface model.
