Presents a new approach to construct validation research: construct modeling. A paradigm shift from functionalism to structuralism in psychology permits 2 types of research to be separated. Construct representation is concerned with identifying the theoretical mechanisms that underlie responses, such as information processes, strategies, and knowledge stores. Three approaches to assessing construct representation are presented: (1) mathematical modeling, particularly as used in cognitive psychology; (2) psychometric modeling, as exemplified by latent trait modeling; and (3) multicomponent latent trait modeling. Nomothetic span is concerned with the network of relationships of a test score with other variables. These 2 types of construct validation research address different issues and require different types of data. For each type of construct validation research, appropriate methods and quantitative models are presented to test a priori hypotheses about construct validity. Examples are presented, and the construct modeling approach is compared with both the traditional psychometric approach and the information-processing approach to establishing theoretical mechanisms in performance.
