Two experiments examined the relation between response variability and sensitivity to changes in reinforcement contingencies. In Experiment 1, two groups of college students were provided complete instructions regarding a button-pressing task; the instructions stated “press the button 40 times for each point” (exchangeable for money). Two additional groups received incomplete instructions that omitted the pattern of responding required for reinforcement under the same schedule. Sensitivity was tested in one completely instructed and one incompletely instructed group after responding had met a stability criterion, and for the remaining two groups after a short exposure to the original schedule. The three groups of subjects whose responding was completely instructed or who had met the stability criterion showed little variability at the moment of change in the reinforcement schedule. The responding of these three groups also was insensitive to the contingency change. Incompletely instructed short-exposure responding was more variable at the moment of schedule change and was sensitive to the new contingency in four of six cases. In Experiment 2, completely and incompletely instructed responding first met a stability criterion. This was followed by a test that showed no sensitivity to a contingency change. A strategic instruction was then presented that stated variable responding would work best. Five of 6 subjects showed increased variability after this instruction, and all 6 showed sensitivity to contingency change. The findings are discussed from a selectionist perspective that describes response acquisition as a process of variation, selection, and maintenance. From this perspective, sensitivity to contingency changes is described as a function of variables that produce response variability.  相似文献

This study reports on several classification issues utilizing the Children's Depression Inventory (CDI), the Child Behavior Checklist-Teacher Form (CBCL-T), and the Peer Nomination Inventory of Depression (PNID). The first sample contained 752 public school children in grades 5, 6, and 9. A second sample of 142 fifth-graders was included to have an additional PNID comparison group. Results revealed moderate correlations between the CDI and the CBCL-T and PNID. Use of multiple criteria for selecting children as depressed was discussed, and selection rates using multiple measures with either strict or lenient cutoff scores were given. Normative data on the PNID were evaluated, and it was suggested that norms for the PNID may not be generalizable to other samples. Finally, race and gender analyses showed that CDI scores for females were significantly higher than for males, whereas CDI scores for Hispanics were significantly higher than for non-Hispanic whites. However, Omega-squared analyses for these two variables showed this to be of little practical significance.  相似文献

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.  相似文献

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.  相似文献

The authors tested the hypothesis that there is a correlation between hemispheric cognitive style and ear temperature. A sample of 100 participants completed a measure of hemispheric cognitive style, the Hemispheric Consensus Prediction Profile. Ear temperatures were taken in 2 sessions, 2 times for each ear at each session. Average left ear temperature was subtracted from average right ear temperature as an index of dominant temperature. Only 56 of the participants showed a stable dominant ear temperature. For these 56 participants, there was a statistically significant positive correlation between scores on the Hemispheric Consensus Prediction Profile and tympanic member temperature (Spearman's ρ =.29, 95% CI [.04,.51]). Individuals with a left hemispheric cognitive style tended to have a warmer left tympanic membrane temperature while those with a right hemispheric cognitive style tended to have a warmer right tympanic membrane temperature. Tympanic membrane temperatures are easily obtained using inexpensive and noninvasive technology. The relationship suggested by these findings may open new opportunities for the study of cerebral asymmetry.  相似文献

This study examines the extent of emergent, outstanding credit card debt among young adult college students and investigates whether any associations existed between this credit card debt and the characteristics of the communities in which these students grew up or lived. Using data (= 748) from a longitudinal survey and merging community characteristics measured at the zip code level, we confirmed that a community's unemployment rate, average total debt, average credit score, and number of bank branch offices were associated with a young adult college student's acquisition and accumulation of credit card debt. For example, a community's higher unemployment rate and lower number of bank branches were associated with a young adult college student's greater accumulated debt. Community characteristics had the strongest associations with credit card debt, especially after controlling for individual characteristics (i.e., a young adult college student's race and financial independence) and familial characteristics (i.e., their parents’ income and parents’ discussions of financial matters while growing up at home). The findings may help to understand the unique roles that communities play in shaping children and young adults’ financial capability, and how communities can be better capacitated to support the financial goals of their residents.  相似文献

I consider the evolution of our relational ideal—its implications for our therapeutic goals, our patients, and for ourselves. Who do we aim to be in the consulting room? How do we view our patient—her potential and her limitations? What are the clinical goals of a relational analysis? What might those goals occlude? In this context I address the historical excesses of our ideal and the ways we may have gone too far.  相似文献

Sexual boundary violations are ghosts that silence and haunt our psychoanalytic communities. In an attempt to break that silence and confront our ghosts, I put together a panel that included a faculty member (Seth Aronson), an institute graduate (Nancy Crown), and an institute candidate (Carina Grossmark). Our task: To address the particular impact of boundary violations on each cohort. Taken together, our aim is to disturb and provoke; that is, to get us all thinking and speaking about the unspeakable.  相似文献
