Systematic reinforcement procedures were used to increase study behavior in the classrooms of three beginning teachers experiencing problems of classroom control. Classroom study rates were recorded during a baseline period. During subsequent experimental periods, the teachers changed one or more reinforcement contingencies (teacher attention, length of between-period break, a classroom game) to bring about increased study rates and concomitant reductions in disruptive behaviors. A brief reversal period, in which these contingencies were discontinued, again produced low rates of study. Reinstatement of the contingencies resulted once again in marked increases in study behaviors.  相似文献

In four experiments Ss were instructed to learn a set of 40 words by producing implicit associative responses to each item (association instructions), by repeating items over and over (repetition instruction), or by using their own devices (neutral instructions). Experiment I showed that recognition memory (RM) accuracy was greatest under association instructions for adults and children and least under repetition instructions for children. The implications of these results for a frequency theory analysis for RM were discussed. Experiments II, III, and IV examined free recall (FR) as a function of encoding instructions at short (1 min) and long (either 90 min or 24 h) retention intervals. FR was worst under repetition instructions, with little overall difference between the association and neutral conditions. However, in Experiments III and IV, using school children, the neutral condition exceeded the others in FR after 90 min but not after 1 min.  相似文献

Despite being a characteristic symptom of schizophrenia, implications for therapy with persons experiencing prominent disorganization have received less attention in the psychotherapy literature than have other aspects of the disorder. As such, formal thought disorder may be viewed largely as a barrier to effective participation in therapy. In contrast, though, a range of writers from varied traditions have stressed that this feature of schizophrenia is meaningful and improved coherence of speech is an important and viable component of treatment and recovery. This paper suggests that an emergent integrative psychotherapy, metacognitive reflection and insight therapy (MERIT), may be well-suited for work with persons experiencing disorganization symptoms. A brief overview of MERIT is provided, followed by a case report of an 18-month course of therapy with a man with severely disorganized speech.  相似文献

Despite its potential for radically reducing the harm inflicted on nonhuman animals in the pursuit of food, there are a number of objections grounded in animal ethics to the development of in vitro meat. In this paper, I defend the possibility against three such concerns. I suggest that worries about reinforcing ideas of flesh as food and worries about the use of nonhuman animals in the production of in vitro meat can be overcome through appropriate safeguards and a fuller understanding of the interests that nonhuman animals actually possess. Worries about the technology reifying speciesist hierarchies of value are more troublesome, however. In response to this final challenge, I suggest that we should be open not just to the production of in vitro nonhuman flesh, but also in vitro human flesh. This leads to a consideration of the ethics of cannibalism. The paper ultimately defends the position that cannibalism simpliciter is not morally problematic, though a great many practices typically associated with it are. The consumption of in vitro human flesh, however, is able to avoid these problematic practices, and so should be considered permissible. I conclude that animal ethicists and vegans should be willing to cautiously embrace the production of in vitro flesh.  相似文献

Black gay and bisexual young men carry a disproportionate burden of HIV in the United States. This study explored Black gay and bisexual young men living with HIV's identification and interpretation of race‐specific cultural messages regarding substance use, sexual activity, and condom use. A total of 36 Black gay and bisexual young men living with HIV (ages 16–24, mean = 20.6 years) from four geographically diverse regions of the United States participated in qualitative in‐depth interviews. Results from this study elucidate the ways in which these young men interpret various forms of race‐specific cultural messages and experiences regarding substance use, sexual activity, and condom use. Participants discussed cultural messages and experiences promoting and discouraging condoms and substance use. Regarding sexual activity, only messages and experiences promoting sex were reported. Across all three categories, messages and experiences promoting risk were predominant. Data further revealed that socially transmitted cultural messages received by young men emanated from multiple sources, such as family, peers, sexual partners, community/neighborhood, and the broader society. Race‐specific cultural messages and experiences should be addressed in interventions for this population, and programs should assist young men in developing a critical consciousness regarding these messages and experiences in order to promote health and well‐being.  相似文献

Evaluating data from interviews with 30 first-time mothers predelivery and postdelivery reveals three pertinent themes: fear of bodily damage, immense pride and awe about producing a baby, and circumscribed terms of true womanhood. Data demonstrate an evolving pressure on some women to deliver vaginally without medical intervention or pain medication and to nurse a baby exclusively without formula as a marker of womanhood. Psychoanalytic theorists have explored the unique trajectory of growth from girlhood to womanhood wrestling with the unconscious meanings of pregnancy and motherhood. Not enough focus has been placed on the unconscious meanings of actual childbirth itself. Qualitative data illustrate the current social pressure on women to adhere to an unspoken norm regarding womanhood. This article examines contemporary issues of awe, fear, and performance anxiety reported by childbearing women and evidences a need to augment our understanding of female psychosexual development around unconscious tasks unique to giving birth.  相似文献
