The Influence of Retention Interval on the US Preexposure Effect: Changes in Contextual Blocking over Time

A number of studies manipulating the length of the interval between conditioning and testing indicate spontaneous recovery from overshadowing, suggesting that certain instances of overshadowing represent a deficit in memory retrieval rather than a failure of animals to form an association between the overshadowed stimulus and the US. The present series of experiments examined the influence of lengthening the retention interval on blocking, another stimulus selection phenomenon that is typically interpreted as an acquisition deficit. The results indicated that when subjects were tested shortly (3 days) after training conditioning to a taste blocked subsequent conditioning to an odor conditioned in compound with that taste (Experiment 1), whereas prior conditioning to an odor did not block subsequent conditioning to a taste conditioned in compound with that odor (Experiment 2). This pattern of results was essentially unchanged when testing occurred at a longer (21-day) retention interval. However, there was evidence of a US preexposure effect in Experiment 2 when subjects in the US ONLY control condition were tested at the 3-day retention interval, but not when testing occurred 21 days after conditioning. Experiments 3 and 4 examined whether this loss of the US preexposure effect over time might actually represent a change in the degree of contextual blocking as the retention interval is lengthened. Exposure to the conditioning context either during the interval between Phase 1 and Phase 2 of conditioning (Experiment 3) or prior to Phase 1 of conditioning (Experiment 4) alleviated this US preexposure effect suggesting that the loss of the US preexposure effect as the retention interval is lengthened observed in Experiment 2 is due to changes in the degree of blocking by contextual stimuli over time. The results are discussed in terms of differential susceptibility of forgetting of two functional roles played by a contextual stimuli in the current situation-context as a CS and context as a retrieval cue for other CS-US associations.     

The Mission and Role of Psychology in a Traumatised and Changing Society: The Case of South Africa

At present there is a “crisis” in psychology in South Africa. A mental health investigation has been initiated and a national task force appointed in order to reform the profession in all its aspects. These events are the result of a deep sense of unease about the mission, relevance and image of the profession and an awareness that mainstream psychology is irrelevant to the nature and needs of the majority black population. Presently psychology in South Africa is at a crossroads. This paper identifies the mental health needs of the majority black population and suggests professional training programmes for future psychologists and the utilisation of services and resources in delivery systems. The article also re-defines the psychologist's role in a divided and traumatised society.     

Background and career orientations of women with mathematical aptitude

A “person-thing” career motivation continuum was tested as a model for structuring this investigation of the personal characteristics and career influences of women in mathematics who entered teaching or nonteaching careers. Women mathematicians who chose to teach were hypothesized to be more person-oriented in career development (i.e., they would be more influenced in the development of career interest by people). In contrast, women who chose careers in mathematically oriented fields, until recently considered nontraditional for their sex (engineering, physical science, accounting, economics, computer science), were expected to be more attracted to the “ideas” or “things” of mathematics.This hypothesis was tested in its null form by comparing personality traits and career influences for two groups of university senior women. Each group was composed of 30 subjects who had elected at least 24 semester credit hours in mathematics. Subjects were randomly selected after individuals were first stratified into two groups, according to whether they chose teaching or nonteaching careers in math-related areas.Second order personality traits derived from subjects' responses to Cattell's 16 PF Questionnaire were employed to assess personality differences. A biographical questionnaire was utilized for collecting data relative to career-influence factors. Multivariate analysis of variance and chi square statistical models were employed for data analysis.The two groups differed significantly in overall personality profiles. This difference was related to the nonteaching group's having scored significantly higher (than did the teaching group) on both the creativity and independence personality factors. Related to career influence, the nonteaching women appeared to develop their interests in mathematics somewhat earlier than did their counterparts who chose to teach. Women teachers were more attracted to their careers because of the influence of people engaged in mathematically oriented work. More of the nonteaching women cited influences associated with mathematics, itself, such as books, demonstrations and independent studies, as paramount in their career decision-making. Also, men were seen as more influential in fostering their career development by the non-teaching group, while in contrast, the teachers chose women as more influential in the development of their interests in mathematics.These findings appear to support the “person-thing” hypothesis associated with the development of career interests for women in mathematics.     

How Clearly Must I See? Art and Ethics in Pedagogical Practice

This essay explores pedagogical practices and ethical obligations in the embrace of cultural and religious diversity by a faculty team in a theological school course. Attention is given to the interplay of art and ethical dilemmas in an educational praxis that calls into question students’ taken‐for‐granted worldviews and theologies. In the first of three sections the writers identify several assumptions they brought to the conduct of the course regarding diversity, art, and pedagogy. The second section describes student encounters with and responses to art from a variety of cultural contexts. The paper concludes with a critical reflection on ethical and political issues arising from pedagogical practices that engage students with art.     

Psychoanalysis, Parents, and God: Julia Kristeva on Subjectivity and the Imaginary Father

This article examines Julia Kristeva's theories of language, subjectivity, and faith. Kristeva's perspectives contain surprising resources for feminist theologians concerned about gender-inclusive language for God. Her concept of the Imaginary father offers a way to understand how God-language functions for person in relation to their subjectivity. Such an understanding can assist feminist thinkers to move beyond contemporary stalemates in theological appropriations of object relations theory, toward new feminist perspectives on subjectivity and new practices for transforming gendered language about God.     

Reactions of third-graders to recognition allocation after being peer-imitated

Being imitated has generally been regarded as a positive experience conducive to reciprocal imitation of and increased attraction to one’s imitator. An experiment on 3rd-graders, in an adaptation of a Thelen-Kirkland paradigm, investigates whether the receipt of public recognition for a good product would simply amplify those positive effects, or would tend to reverse them, and explores whether gender would moderate models, reactions under such conditions. Recognition allocation was manipulated by having an “authority” award a symbolic star solely to the model, to the confederate imitator alone, to the confederate nonimitator alone, or to no one. The results suggested that the boys rather than girls showed amplification effects of receiving sole recognition: they reciprocally imitated more, and expressed greater attraction to, their same-sex imitator than did the girls. Overall, models expressed relatively less attraction to the imitator than to the nonimitator. When interviewed, the models were equally divided as to which of the two deserved the recognition when they themselves or their imitator received it, but they stated unequivocally that the nonimitator who received the recognition deserved it. They also clearly stated a preference for those tasks on which they themselves had been imitated—given that they themselves or their imitator had received recognition credit, compared to models in the nonimitator-recognition and control conditions. It is clear that recognition allocation is an important construct that should be considered in investigating models, reactions to being imitated, particularly in the light of its significance in the adult world, at least of this culture. Several directions are proposed for pursuing this construct further.     

Grey Matter: Ambiguities and Complexities of Ethics in Research

Ethical dilemmas are often not discussed in the dissemination of educational research. While the ethical guidelines for research seem clear at first glance, a closer look at the intimate nature of qualitative research reveals that there are many ambiguities or ‘grey’ areas where researchers must rely on their personal value systems. This article discusses the challenges faced by an experienced educator, although novice researcher, in considering the ethical parameters of her own research with adolescents with hearing loss. In particular, the grey ethical areas identified by the researcher include: (a) vulnerable population; (b) researcher role confusion; (c) consent; (d) privacy, confidentiality, and anonymity; as well as (e) the nature of risk. Based on the author’s own reflections on beginning the research process, the article presents possible pitfalls and ways of overcoming the possibility of becoming immobilized by the ethical enigmas of research.     

Keeping the Spirit of Community Partnerships Alive in the Scale Up of HIV/AIDS Prevention: Critical Reflections on the Roll Out of DEBI (Diffusion of Effective Behavioral Interventions)

DEBI, or the Diffusion of Effective Behavioral Interventions is the largest centralized effort to diffuse evidence-based prevention science to fight HIV/AIDS in the United States. DEBI seeks to ensure that the most effective science-based prevention interventions are widely implemented across the country in community-based organizations. Thus, this is a particularly timely juncture in which to critically reflect on the extent to which known principles of community collaboration have guided key processes associated with the DEBI rollout. We review the available evidence on how the dissemination of packaged interventions is necessary but not sufficient for ensuring the success of technology transfer. We consider additional principles that are vital for successful technology transfer, which were not central considerations in the rollout of the DEBI initiative. These issues are: (1) community perceptions of a top-down mode of dissemination; (2) the extent to which local innovations are being embraced, bolstered, or eliminated; and (3) contextual and methodological considerations that shape community preparedness. Consideration of these additional factors is necessary in order to effectively document, manage, and advance the science of dissemination and technology transfer in centralized prevention efforts within and outside of HIV/AIDS.
