Contingency management (CM) for drug abstinence has been applied to individuals independently even when delivered in groups. We developed a group CM intervention in which the behavior of a single, randomly selected, anonymous individual determined reinforcement delivery for the entire group. We also compared contingencies placed only on cocaine abstinence (CA) versus one of four behaviors (CA, treatment attendance, group CM attendance, and methadone compliance) selected randomly at each drawing. Two groups were formed with 22 cocaine-dependent community-based methadone patients and exposed to both CA and multiple behavior (MB) conditions in a reversal design counterbalanced across groups for exposure order. The group CM intervention proved feasible and safe. The MB condition improved group CM meeting attendance relative to the CA condition. 相似文献

This study assessed whether attendance rates in a workplace predicted subsequent outcome of employment-based reinforcement of cocaine abstinence. Unemployed adults in Baltimore methadone programs who used cocaine (N = 111) could work in a workplace for 4 hr every weekday and earn $10.00 per hour in vouchers for 26 weeks. During an induction period, participants provided urine samples but could work independent of their urinalysis results. After the induction period, participants had to provide urinalysis evidence of cocaine abstinence to work and maintain maximum pay. A multiple regression analysis showed that induction period attendance was independently associated with urinalysis evidence of cocaine abstinence under the employment-based abstinence reinforcement contingency. Induction period attendance may measure the reinforcing value of employment and could be used to guide the improvement of employment-based abstinence reinforcement. 相似文献

The National Health Service (NHS) National Genetics Education and Development Centre was established by the Department of
Health in 2004 to help drive and co-ordinate genetics education for health professionals working outside specialist genetic
services. This paper reviews the experiences and lessons learned to date. At the outset, it was clear that understanding the
learning ethos, preferred delivery methods and attitudes towards genetics of different NHS healthcare groups was vital. We
collected evidence by undertaking needs assessments with educators, practitioners and patients. We have determined the genetics
knowledge, skills and attitudes which they said were needed and translated these into learning outcomes and workforce competences
in a continuum of education. Beginning with core concepts introduced (and examined) pre-registration, the continuum continues
with development of concepts post-registration as appropriate for role, leading to practical application and assessment of
competences in the workplace. These are supported by a portfolio of resources which draw heavily on patient based scenarios
to demonstrate to staff that genetics is relevant to their work, and to convince educators and policy makers that genetic
education is likely to result in real clinical benefit. A long term educational policy, inclusive of learners, educationalists
and their institutions must be evidence based, flexible and responsive to changes in workforce structure, provision of clinical
services and conceptual and financial commitments to education. The engagement of national policy, regulatory and professional
bodies is vital (). 相似文献

This study investigated the effects of a dependent group-oriented contingency on the supportive and non-supportive fair play behaviors of 6th grade students engaged in volleyball games as part of their physical education instruction. Six students, one male and one female per class, from three classes, identified as demonstrating low incidences of supportive behaviors during volleyball games, were participants in this study. A multiple baseline across classes design was used to examine the data. During baseline few incidences of non-supportive behaviors occurred among all six students. However, the participants seldom displayed supportive behaviors during games (i.e., encouraged each other). Following the introduction of the dependent group contingency, supportive behaviors for all participants increased. Follow-up data, collected in an alternative setting, indicated variable maintenance. The results are discussed in the context of group contingencies and social behaviors in sports. 相似文献

Abstract: Detecting contingency between self-produced actions and the consequences plays a crucial role for basic cognitive functions, such as construction of self body-image and tool-use. This paper reviews our recent studies focusing on the temporal aspect of contingency. Three studies concerning the detection of proprioceptive-visual contingency in infants, children and adults are summarized. All of these studies use delayed self-image as a tool to investigate the temporal aspect of contingency detection. Based on the results of these studies and related preceding research, the paper proposes the ubiquity of a contingency detector among the development of self and social interaction. 相似文献

Discovering whether children prefer reinforcement via a contingency or independent of their behavior is important considering the ubiquity of these programmed schedules of reinforcement. The current study evaluated the efficacy of and preference for social interaction within differential reinforcement of alternative behavior (DRA) and noncontingent reinforcement (NCR) schedules with typically developing children. Results showed that 7 of the 8 children preferred the DRA schedule; 1 child was indifferent. We also demonstrated a high degree of procedural fidelity, which suggested that preference is influenced by the presence of a contingency under which reinforcement can be obtained. These findings are discussed in terms of (a) the selection of reinforcement schedules in practice, (b) variables that influence children's preferences for contexts, and (c) the selection of experimental control procedures when evaluating the effects of reinforcement. 相似文献

Pigeons acquired discriminated key pecking between 528- and 540-nm stimuli by either a response-reinforcer (operant group) or a stimulus-reinforcer (autoshaped group) contingency, with other training-schedule parameters comparable over groups. For the birds in the operant group, key pecks intermittently produced grain in the presence of one hue on the key (positive stimulus) but not in the other (negative stimulus). For the birds in the autoshaped group, pecking emerged when grain was intermittently presented independently of key pecking during one key color but was not presented during the other key color. Two independent contingency assays, peck-location comparisons and elimination of differences in reinforcement rate, confirmed the effectiveness of the two training procedures in establishing operant or respondent control of key pecking. After reaching a 10:1, or better, discrimination ratio between key pecks during the two key colors, the birds received a wavelength generalization test. Criterion baseline key-peck rates were comparable for operant and autoshaped groups prior to testing. On the generalization test, performed in extinction, all birds pecked most at a stimulus removed from the positive training stimulus in the direction away from the negative stimulus. In testing, autoshaped "peak" rates (24.5 to 64.9 pecks per minute) were from 33% to 80% higher than rates in the presence of the training stimuli. Respondent peak shift rarely has been reported heretofore, and never this consistently and robustly. These results further confirm the similarity of perceptual processing in classical and operant learning. They are discussed in terms of Spence's gradient-interaction theory and Weiss' (1978) two-process model of stimulus control. 相似文献

Consideration will be given to a model developed by Rasch that assumes scores observed on some types of attainment tests can
be regarded as realizations of a Poisson process. The parameter of the Poisson distribution is assumed to be a product of
two other parameters, one pertaining to the ability of the subject and a second pertaining to the difficulty of the test.
Rasch's model is expanded by assuming a prior distribution, with fixed but unknown parameters, for the subject parameters.
The test parameters are considered fixed. Secondly, it will be shown how additional between- and within-subjects factors can
be incorporated. Methods for testing the fit and estimating the parameters of the model will be discussed, and illustrated
by empirical examples. 相似文献

Abstract. This essay suggests some future items for an agenda about human viability, defined as survivability with meaning and purpose, by exploring interrelations between nature, humanity, and the work of God. It argues for intrinsic and creative value in nature, so there is a value kinship, as well as a factual kinship, between humans, nature, and God-working. It considers humans as "webs of culture, life, and cosmos" and suggests some implications of this notion of human nature for viability. And it asks what human fulfillment can be in light of the awesome creative-destroying-recreative activity that seems to be the ground of an evolving universe. 相似文献
