Construct validity of the Rosenzweig Picture-Frustration Study

Projective and semiprojective techniques are both tools and tests. A schema for assessing the validity of projective devices is proposed: (1) Primary, consisting of (a) construct validity i.e., the soundness of the techniques vis-a-vis its underlying concepts; and (b) criterion-related validity, i.e., the concordance between tool results and specified external criteria. (2) Secondary, viz., pragmatic validity, i.e., the usefulness of the instrument in applied fields. Discussion then focuses on the construct validity of the conceptually-based, semiprojective Rosenzweig P-F Study. specifically the evidence on (a) the self-consistency of its conceptual dimensions; (b) the sequential. social development of the Types and Directions of Aggression; (c) levels of behavior elicited; (d) sensitivity to scorable changes after induced frustration: and (e) physiological correlates oft he aggression categories. In each of these areas evidence exists in support of the validity of the P-F Study.     

Two operations in character recognition: Some evidence from reaction-time measurements

Theories of the recognition of a visual character may be divided into three sets.defined by the way in which the stimulus is encoded before being compared to a memorized target character. A character-classification experiment was performed in which the test stimuli were characters that were either intact or degraded by a superimposed pattern. Analyses of reaction-times in the experiment lead to the rejection of two of the three sets of theories. There appear to be at least two separate operations in the recognition or classification of a character. The first encodes the visual stimulus as an abstracted representation of its physical properties. The second, which may occur more than once, compares such a stimulus representation to a memory representation, producing either a match or a mismatch. A theory of high-speed exhaustive scanning in memory underlies the experiment and is given new support. The method of reaction-time analysis that is introduced, an elaboration of the Uelmholtz-Donders subtraction method, may be applicable to the general problem of the invariance ofperceived form under certain transfomations of the stimulus.     

Introduction to the Symposium on Drug Improvement of Memory

This paper introduces a symposium in which three main speakers discussed the prospect that drugs may improve cognitive functioning, including memory. Even though the participants agreed that presently available drugs can alleviate memory disorders only to a limited extent and do not increase ability of well-functioning individuals, it is important to consider social implications of drugs that might increase learning ability and intelligence. It is also important to consider, as alternatives to drugs, behavioural approaches to improving abilities that do not share possible drawbacks of pharmacological treatments.     

An investigation of the reliability of the Rosenzweig Picture-Frustration (P-F) Study, Children's Form

Presents data on the retest and split-half reliability of the Rosenzweig Picture-Frustration (P-F) Study, Children's Form, for two groups of subjects (aged 10-11 and 12-13 years, respectively), each group tested twice at an interval of three months. It was found that the retest reliability for all scoring categories (except O-D) were statistically significant (.01 or .05 level). GCR proved stable for the younger group (r = .53) but not for the older group. The difference here may be due to the less comfortable retest conditions prevailing for the older subjects. Reliability by retest was consistently higher than by the less appropriate split-half method, but the latter proved, nevertheless, to be in the main favorable.     

Parfit on Free Will,Desert, and the Fairness of Punishment

In his recent monumental book On What Matters, Derek Parfit argues for a hard determinist view that rejects free will-based moral responsibility and desert. This rejection of desert is necessary for his main aim in the book, the overall reconciliation of normative ethics. In Appendix E of his book, however, Parfit claims that it is possible to mete out fair punishment. Parfit’s position on punishment here seems to be inconsistent with his hard determinism. I argue that Parfit is mistaken here, in a way that leads him to unjustified optimism about the possibility of fair penalization. Insofar as we take the free will problem seriously, we cannot reconcile a belief in the absence of desert with a belief in the fairness of penalization.     

“Idiographic” vis-à-vis “idiodynamic” in the historical perspective of personality theory: Remembering Gordon Allport, 1897–1997

The centenary of Gordon W. Allport provides an occasion for reappraising his special position regarding uniqueness in personality. Allport's theory of personality, as first presented in his 1937 textbook, highlighted the idiographic in conjunction with the nomothetic approach, and the fundamental unit in his formulation was the trait. He described common and unique traits as well as the unique organization of traits. In contradistinction, the idiodynamic orientation, introduced by Saul Rosenzweig in 1951 and, in more detail in 1958, focused on events which over a lifespan constitute an idioverse—a population of phenomenological events. Allport's original emphasis on the idiographic and his later confusion concerning idiodynamics, can, in considerable measure, be understood by recognizing the role of religious spirituality in his conception of the person. That conception, which derived from an early religious indoctrination, asserted itself with renewed vigor in his later years. His scientific conception of personality thus remained unconsummated, subordinated by him to the unsolvable mysteries of ontology which properly belong, he believed, in the domain of faith. © 1997 John Wiley & Sons, Inc.
