This paper emphasizes the .need to go beyond structural models of personality and intellect to develop sequential models of psychological process, particularly for such complex phenomena of prime concern to theory and application as learning, problem solving, and creativity.It is further argued that factor analysis, in a multitude of studies of cognition and personality over the past fifty years, has already delineated many relevant process variables that might serve as components in these sequential models.Beyond Structure:In Search of Functional Models of Psychological Process lSilvan Tomkins (1962) once remarked that it seemed to him that human personality was "organized as a language is organized, with elements of varying degrees of complexity-~from letters, words, phrases, and sentences to styles--and with a set of rules of combination which enable the generation of both endless novelty and the very high order of redundancy which we call style." He went on to note that "if we had to be blind about one or the other of these types of components, we should sacrifice the elements for the rules, l' although "factor analysis appears to have made the opposite decision. It would tell what letters, or words, or phrases, or even styles were invariant and characteristic of a personality or of a number of personalities," but by itself it does not and cannot "generate the rules of combination which together with the elements constitute personality" (Tomkins, 1962, p , 287).The use of language as a prototype for psychological functioning is not new. Lashley (1951), for example, pointed to the generality of the problem of syntax. He maintained that most processes of both thought and action were sequential, thereby entailing an essential problem of serial order--not just of elements but of hierarchies of organization (e.g., the order of vocal movements in pronouncing a word, the order of words in a sentence, the order of sentences in a paragraph, the order of paragraphs in a rational discourse). One of the most critical tasks for psychology is to explicate the syntax of thought and of behavior,-2-to uncover the generalized schemata of action which determine the sequences of specific component acts, thereby moving psychological theories from the level of rhetoric to the level of grammar.The aims of the present paper are to affirm the importance of developing sequential models of psychological process--particularly of such complex psychological phenomena of prime concern to theory and application as learning, problem solving, and creativity--and to argue, as Tomkins (1962) has already backhandedly allowed, that factor analysis in a multitude of studies of cognition and personality over the past fifty years may have delineated many important component processes for these sequential models.Factor analysis attempts to derive from consistent individual differences in complex, multiply-determined behaviors a limited set of underlying component variables which in weighted combination would account for the observed covariat...
