ItemJournal of Multivariate Experimental Personality and Clinical Psychology, v.3, no.1 (complete version)(Wichita State University, Department of Psychology, 1977) ItemROTOPLOT II: A program for visually guided graphical rotation with Procrustes and congruence coefficients(Wichita State University, Department of Psychology, 1977) Burdsal, Charles A.An improved version of ROTOPLOT, ROTOPLOT II, was presented in this article. ROTOPLOT described a computer assisted strategy enable one to perform visually guided graphical rotations upon pairwise combinations of factors. ROTOPLOT II, expanded upon this routine by adding the options of Procrustes and the derivation of congruence coefficients. Step by step instructions for use of the strategy were included, and a source for the computer program was discussed, as were its uses and limitations. ItemAn experimental alteration of motivation levels in adolescents(Wichita State University, Department of Psychology, 1977) Krug, Samuel E.Two experiments were carried out within the framework of Cattell's motivation theory. Results demonstrated that dynamic trait factors, each of which encompasses a wide spectrum of specific attitudes, are functionally unitary entities, since manipulation of only one component attitude (e.g., fear of war) results in changes on related attitudes (e.g., fear of illness, fear of parental rejection). The experiments further clarified the theoretical nature of drive stimulation and drive frustration within the context of this motivational theory. ItemInterface of Alston's conceptual analysis of trait theory and Cattell's multi-trait theory of personality(Wichita State University, Department of Psychology, 1977) Buss, A. R.In a recent series of papers and articles, W.P. Alston has taken a close look at the conceptual structure of the term "trait." In applying Alston's conceptual distinctions to the substantive multi-trait theory of R.B. Cattell, it is argued that Alston has too narrow a view as to how the term "trait" is in fact used, and how it should be used. Contrary to Alston's point of view, it is argued that trait concepts are indeed theoretical constructs rather than simply being terms summarizing behavioral regularities. Notwithstanding the case made against Alston's characterization of trait concepts, itis pointed out that multi-trait theories can be improved by taking seriously some of the distinctions that he has made, although not for all the reasons that he has given. ItemEvidence for the 16PF primary and secondary factors(Wichita State University, Department of Psychology, 1977) Bolton, Brian, 1939-Brief reviews of the published factorial studies of the 16PF suggest that the evidence is divided regarding the existence of the 16 primary factors. There is considerable convergence at the secondary level, however. In the present investigation factor analyses of 128 items, 32 parcels, 16 scales, and 16 change scores derived from the 16PF-E using a heterogeneous sample of rehabilitation clients provided strong confirmation of the eight 16PF secondaries and, by implication, support for the existence of the 16 primaries. It is concluded that all available evidence, when considered from an objective point of view, does not justify the negative conclusions reached by the more severe critics of the 16PF.
