Effects of a variable-ratio conditioning history on sensitivity to fixed-interval contingencies in rats.

We investigated the possibility that human-like fixed-interval performances would appear in rats given a variable-ratio history (Wanchisen, Tatham, & Mooney, 1989). Nine rats were trained under single or compound variable-ratio schedules and then under a fixed-interval 30-s schedule. The histories produced high fixed-interval rates that declined slowly over 90 sessions; differences as a function of the particular history were absent. Nine control animals given only fixed-interval training responded at lower levels initially, but rates increased with training. Despite differences in absolute rates, rates within the intervals and postreinforcement pauses indicated equivalent development of the accelerated response patterns suggestive of sensitivity to fixed-interval contingencies. The finding that the histories elevated rates without retarding development of differentiated patterns suggests that the effective response unit was a burst of several lever presses and that the fixed-interval contingencies acted on these units in the same way as for single responses. Regardless of history, the rats did not manifest the persistent, undifferentiated responding reported for humans under comparable schedules. We concluded that the shortcomings of animal models of human fixed-interval performances cannot be easily remedied by including a variable-ratio conditioning history within the model.     

Jungian Psychology, the Body, and the Future

Impressive reaffirmation of Jung's archetypal hypothesis has come from developments in behavioural biology (Tinbergen 1951; Cosmides 1985), psycholinguistics (Chomsky 1965), structural anthropology (Lévi-Strauss 1967), developmental psychology (Bowlby 1969), dream research (Jouvet 1975). neuroscience (MacLean 1976), sociobiology (Wilson 1978), and evolutionary psychiatry (Gardner 1988; Gilbert 1989). A close correspondence exists between Jungian theories of dreaming in human beings and modern biological theories of dreaming in animals. A paradigm shift is under way in the direction of a growing cross-disciplinary awareness that all human sciences are about archetypal manifestations and that these apply as much to the body as to the mind. Jungian psychology must keep abreast of these developments if it is not to be sidelined and superseded by less humane therapeutic philosophies.     

A general linear model for estimating effect size in the presence of publication bias

When the process of publication favors studies with smallp-values, and hence large effect estimates, combined estimates from many studies may be biased. This paper describes a model for estimation of effect size when there is selection based on one-tailedp-values. The model employs the method of maximum likelihood in the context of a mixed (fixed and random) effects general linear model for effect sizes. It offers a test for the presence of publication bias, and corrected estimates of the parameters of the linear model for effect magnitude. The model is illustrated using a well-known data set on the benefits of psychotherapy.Authors' note: The contributions of the authors are considered equal, and the order of authorship was chosen to be reverse-alphabetical.     

Implications of college-age narcissism for psychosocial functioning at midlife: Findings from a longitudinal study of women

Positive and negative implications of two types of college-age narcissism on psychosocial functioning at midlife were studied in a longitudinal sample of women. Both types were scored with self-report measures when the women were, on the average, age 21. Throughout the first half of their adult life, high scorers on covert narcissism presented themselves as lacking in confidence and having low morale; high scorers on overt narcissism described themselves as wanting admiration, being independent, and being forceful. Positive outcomes associated with covert narcissism included the development of insight and of a differentiated sense of the self and, in the case of overt narcissism, entailed an involvement in high-status and creative work careers. At midlife, high scorers on covert narcissism experienced negative affect and feelings of being neglected, whereas high scorers on overt narcissism experienced family conflict and problems with impulse control. The personality characteristics associated with both types of narcissism remained stable from the early 20s to early 50s.     

Socialization for the democratic personality in modern society

A comprehensive analysis of socialization requires a complex model that both explicates and synthesizes the various subprocesses involved in this phenomenon. Traditional concerns with socialization that have focused almost exclusively on its objective functions, that is, on those which serve society and its institutions, need to be complemented by an equal emphasis on subjective functions in terms of the sociological and psychological development of the individual. Chiefly relevant in this latter respect is the production of basic human needs and the consequences that result from their inadequate gratification in unauthentic and/or unresponsive societies. One such outcome that is particularly crucial to both personal and societal function is that of alienation, which can be assessed specifically in terms of its significance for civic participation. Our model recognizes the limits of both human systems and social systems; and, in terms of the principles of authenticity and responsivity, it articulates the linkage among these systems constituting the essence of socialization. Our model also provides an implicit clarification of the nature and meaning of citizenship in a democracy, which by definition should be a responsive society, and delineates the required sociopsychological images for maximizing the role of political participation.     

Ethics education in science and engineering: The case of animal research

Conclusion The past one hundred fifty years of debate over the use of animals in research and testing has been characterized mainly byad hominem attacks and on uncritical rejection of the other sides’ arguments. In the classroom, it is important to avoid repeating exercises in public relations and to demand sound scholarship. This paper is a modification of material originally included in the handbook which accompanied the American Association for the Advancement of Science (AAAS) Seminar “Teaching Ethics in Science and Engineering”, 10–11 February 1993.     

The relationship between qualitative and quantitative research: Lessons from feminist psychology

The dominant methodological approach in psychological research has involved the use of quantitative methods within a positivist framework. In this article we argue that both qualitative and quantitative methods have their strengths and limitations, depending on the research question under investigation. We examine some of the advantages of qualitative methods, paying particular attention to the value of such methods for feminist researchers. We challenge the positivist assumption that all research should be apolitical and value-free, arguing that the political context in which all research studies take place plays an important role in decisions about the appropriate research methods to use. Despite the value attached to qualitative methods by feminist researchers, there may be projects for which quantitative methods, or a combination of qualitative and quantitative techniques, are more suitable. We draw on examples from our research on the transition from school to the job market for young people, and a study of 16- to 19-year-old first time mothers to illustrate these points, examining the practical implications of our arguments for applied social psychology research.     

Ecology, Community, and AIDS Prevention

I explore the role that may be played by an ecological view of AIDS prevention and AIDS-related social concerns. The study of AIDS risk behavior and interventions designed to prevent AIDS have challenged Health Psychology's typically individualistic perspective. Issues of empowerment, psychological sense of community, interpersonal ties, resources, and culture are central to an understanding of risky sexual behavior and helping people to guard themselves from the threat of AIDS. However, despite Community Psychology's historical expertise in these areas, the field has only recently become involved in AIDS prevention efforts. I outline how resource-based, ecological theories may prove more helpful in addressing the AIDS pandemic than the individual, cognitive theories that have typically been adopted. Sexual behavior and associated risk are tied not simply to people's personal behavior and thoughts but to the likelihood of disease exposure in their ethnic group, the power and choices associated with power in that group, and the alternative means available of meeting their overall sexual, romantic, economic, and social goals. As such, AIDS research and intervention must simultaneously address the individual, social, and cultural spheres if insights that can translate to meaningful change can be expected to occur.     

Developing the matrix representation grid (MRG): A method for observing group processes. Findings from time-limited group psychotherapy for alcohol-dependent patients

The MRG was published 1988 in order to support developments in group psychotherapy methods as one of the all too few process observation research methods for studying group-as-a-whole. After 9 years of what pilot studies have labeled successful clinical trials, this study aims at validating the MRG against the established SAVI: Structural Analysis of Verbal Interaction (Agazarian & Simon 1989). Videotaped group sessions from short-term groups for alcohol dependent patients conducted along two therapy methods, one behaviorally oriented and the other group analytic, are used as material. The MRG is validated in the study, confirmed to be clinically valuable, and some interesting comparisons between the two treatment modalities are also made.
