Person-centered theory and the contemporary practice of psychological testing

This paper examines the effects of person-centered theory on contemporary psychological testing. Seven basic ideas or assumptions, which are integral to and guide the testing process, are identified and briefly discussed. Each idea is considered to have been affected either directly or indirectly by person-centered philosophy. Some of the ways in which these ideas are reflected in contemporary testing practice are indicated.     

Arguing about definitions

What are the implications of taking seriously Chaïm Perelman's proposition that “definitions are rhetorical”? Efforts to find Real Definitions are dysfunctional to the extent they direct argumentation toward pseudo “is” claims and away from explicit “ought” claims about how words are to be used. Addressing definitional disputes explicitly as propositions ofought rather thanis could put on the agenda the pragmatic concerns of definitional choice that might otherwise remain tacit.     

Twenty-five basic theorems in situation and world theory

Conclusion The foregoing set of theorems forms an effective foundation for the theory of situations and worlds. All twenty-five theorems seem to be basic, reasonable principles that structure the domains of properties, relations, states of affairs, situations, and worlds in true and philosophically interesting ways. They resolve 15 of the 19 choice points defined in Barwise (1989) (see Notes 22, 27, 31, 32, 35, 36, 39, 43, and 45). Moreover, important axioms and principles stipulated by situation theorists are derived (see Notes 33, 37, and 38). This is convincing evidence that the foregoing constitutes a theory of situations. Note that worlds are just a special kind of situation, and that the basic theorems of world theory, which were derived in previous work, can still be derived in this situation-theoretic setting. So there seems to be no fundamental incompatibility between situations and worlds — they may peacably coexist in the foundations of metaphysics. The theory may therefore reconcile two research programs that appeared to be heading off in different directions. And we must remind the reader that the general metaphysical principles underlying our theory were not designed with the application to situation theory in mind. This suggests that the general theory and the underlying distinction have explanatory power, for they seem to relate and systematize apparently unrelated phenomena.This research was conducted at the Center for the Study of Language and Information (CSLI). I would like to thank John Perry for generously supporting my research both at CSLI and in the Philosophy Department at Stanford. I would also like to thank Bernard Linsky, Chris Menzel, Harry Deutsch and Tony Anderson for many worthwhile and interesting suggestions for improving the paper. An earlier version of the paper, more narrowly focused on situation theory, has appeared in Zalta (1991).     

Continuous and discrete latent structure models for item response data

Relations are examined between latent trait and latent class models for item response data. Conditions are given for the two-latent class and two-parameter normal ogive models to agree, and relations between their item parameters are presented. Generalizationss are then made to continuous models with more than one latent trait and discrete models with more than two latent classes, and methods are presented for relating latent class models to factor models for dichotomized variables. Results are illustrated using data from the Law School Admission Test, previously analyzed by several authors.     

Illusory correlation and the maintenance of sex role stereotypes in children

The present work tested the hypothesis that children would perceive illusory correlations leading to greater recall of events that confirm rather than disconfirm sex-stereotypic beliefs. In the study, 33 second graders and 34 fourth graders were shown slides of adult males and females engaged in traditional sex role activities, nontraditional activities, and gender-neutral activities. Frequency judgments of the occurrence of each Stimulus Type x Stimulus Sex category served as the dependent measure. In actuality there was no correlation between gender and activity type in the stimulus set. As expected, both age groups perceived illusory correlations, giving the highest frequency estimates to traditional stimuli and the lowest frequency estimates to nontraditional stimuli. Individual differences in level of stereotyped attitudes had no effect on this cognitive bias. Results are discussed in terms of gender schema theory and the maintenance of sex role stereotypes.This research was supported by grants to the first author from the University of Pittsburgh at Johnstown and the Pennsylvania State System of Higher Education. We wish to express our appreciation to Lynn Liben and Margaret Signorella for the use of their stimuli. We would also like to thank the administrators, teachers, and students whose cooperation made the project possible. An earlier version of this paper was presented at the 59th annual meeting of the Eastern Psychological Association, Buffalo, NY, April 1988.     

The Future of Psychology in Family Medicine

Psychology has been integral to the field of family medicine since its inception as a medical specialty in the 1960s. Psychologists and other behavioral scientists contribute to family medicine in teaching clinical skills, in defining research questions, in developing research methodology, and in creating integrated physical/mental health care delivery systems. Future developments in the field of psychology in family medicine are likely to emphasize development and evaluation of screening measures which identify mental health problems in primary care, development of early intervention for those mental health problems, and more precise measurement of process and quality of care and health outcomes. Psychologists have an important role to fulfill in educating physicians on alternatives to pharmacologic and medical interventions for common presenting problems in primary care. However, current economic forces shaping the practice of medicine may work against further enhancing the efficacy of the physician in dealing with psychosocial issues. The future role of psychology in family medicine is not yet delineated, and while the move toward parity of reimbursement for mental and physical health care delivery may enhance this collaboration, there is a need to continue to evaluate how the psychological well-being of patients is influenced in the evolution of new models of care delivery.     

Capacity and retention capability of working memory modify the strength of the RT/IQ correlation: a short note

The limited capacity theory assumes that working memory (WM) has limited capacity to process information and, at the same time, to store other pieces of information, necessary for further processing. Quick processing of data is supposed to be the only way to solve the task without the risk of losing vital pieces of information. We predicted, then, that the correlation between mental speed, measured by reaction time (RT), and the intelligence quotient (IQ) should not appear in the case of persons who possess a relatively capacious WM store, or who show increased retention capability of their WM store. Such persons do not need to be fast, whereas, for people who show poorer indices of capacity or retention capability of WM, mental speed is the only way to tackle a complex and difficult intellectual task. As predicted, the RT/IQ correlation appeared much stronger in the group of subjects characterized by lower retention capability and capacity of WM.

Extracting the coherent core of human probability judgement: a research program for cognitive psychology

Human intuition is a rich and useful guide to uncertain events in the environment but suffers from probabilistic incoherence in the technical sense. Developing methods for extracting a coherent body of judgement that is maximally consistent with a person's intuition is a challenging task for cognitive psychology, and also relevant to the construction of artificial expert systems. The present article motivates this problem, and outlines one approach to it.
