The results from five experiments are considered in relation to two of Spence's (1937, 1938) proposals concerning discrimination learning. In Experiments 1 and 2, we investigated whether his ideas about the interaction between excitatory and inhibitory generalization gradients can be used to understand how animals solve a complex patterning discrimination. The results supported a development of his proposals as put forward by Pearce (1994), provided a modification was made to Pearce's rulefor determining the shape ofthe generalization gradient. In Experiments 3, 4, and 5, we examined whether animals would pay more attention to stimuli that are relevant, rather than irrelevant, to the solution of a discrimination. The results supported this proposal for stimuli comprising visual patterns, but not for those comprising plain colors. The results also indicated that change of attention was a consequence of preliminary receptor-exposure acts, as envisaged by Spence, and not of more central changes in attention. 相似文献

AbstractRecently, researchers have used multilevel models for estimating intervention effects in single-case experiments that include replications across participants (e.g., multiple baseline designs) or for combining results across multiple single-case studies. Researchers estimating these multilevel models have primarily relied on restricted maximum likelihood (REML) techniques, but Bayesian approaches have also been suggested. The purpose of this Monte Carlo simulation study was to examine the impact of estimation method (REML versus Bayesian with noninformative priors) on the estimation of treatment effects (relative bias, root mean square error) and on the inferences about those effects (interval coverage) for autocorrelated multiple-baseline data. Simulated conditions varied with regard to the number of participants, series length, and distribution of the variance within and across participants. REML and Bayesian estimation led to estimates of the fixed effects that showed little to no bias but that differentially impacted the inferences about the fixed effects and the estimates of the variances. Implications for applied researchers and methodologists are discussed. 相似文献

The University of Southern California has conducted a series of 24 surveys of the professional activities of physicians and surgeons in the United States. The surveys encompass more than 10,000 respondents representing 65.8% of all practising physicians in the United States and its territories. Using a specially‐developed “log‐diary” recording instrument, these physicians reported data on the care they provided during hundreds of thousands of encounters with their patients. This article provides an exposition of the study's unique methodology, presents illustratative data for 5 of the 24 specialities surveyed (cardiology, family practice, general internal medicine, orthopaedic surgery and psychiatry), and discusses the study's relevance and implications for medical education. 相似文献

The demographics of 21st century, community college students are changing. Success strategies are being developed with adult learners in mind, particularly for programs targeting students already in the workforce. While recognizing that such students may have been out of college for an extended time or have obligations differing from traditional college students, such as family and work commitments, programs designed for adult learners should provide clearly articulated pathways to success. Elements of this success strategy should provide instruction in a way that accommodates work schedules and prepares students for classroom challenges.
Degree programs should be designed to help students complete coursework quickly and provide greater access to educational opportunities. Gillette College’s accelerated Mining Technology Program combines a no-options pathway to completion. It is a course delivery system allowing students who otherwise might not have the opportunity to attend college the ability to earn a degree in their career field. To further increase student success, the program relies on strategic and intrusive advising to energize students who may not be used to academic demands. 相似文献

Organizational culture and effectiveness in two-year colleges 总被引:2,自引:0,他引:2
The central purpose of this study is to determine the extent to which the effectiveness of a nationally representative sample of two-year colleges differs in terms of their dominant type of organizational culture. The findings demonstrate wide differences in the effectiveness of two-year colleges that exhibit the traits of clan, adhocracy, hierarchy, and market cultures, and the differences are consistent with their conceptual rationale. The research, policy, and practical implications of the findings in terms of our efforts to understand and improve the management and institutional performance of two-year colleges are discussed.Presented at the Association for Institutional Research Annual Forum, Atlanta, Georgia, May 10–13, 1992. 相似文献

The vision of the public schools as the “great equalizers” of society is as yet unfulfilled. One of the reasons why the schools have not achieved this goal is attributable, in part, to the administration of the public school system. This article examines the nature of school bureaucracy in light of the power it grants to some and denies to others. Second, it is shown that the nature of administrative acts can work to displace the goals society has set for the schools. Third, the political nature of school administration is examined. The article concludes with reference to several significant changes occurring in educational administration: “marketplace politics”; the productivity movement; and collective choice policymaking. 相似文献

Active learning involves students engaging with course content beyond lecture: through writing, applets, simulations, games, and more (Prince, 2004). As mathematics is often viewed as a subject area that is taught using more traditional methods (Goldsmith &; Mark, 1999), there are actually many simple ways to make undergraduate mathematics courses more active, starting with the discussion of the syllabus. This article describes simple ways to turn course introductions, review of prior knowledge, and formative assessment into active learning experiences for students. 相似文献

Two experiments tested two cynomolgus monkeys’ self-control—choice of a longer, more delayed reinforcer over a shorter, less delayed reinforcer. In Experiment 1, subjects exhibited significant selfcontrol in a procedure in which reinforcer amounts and delays were held constant throughout a condition. In Experiment 2, subjects exhibited significantly greater sensitivity to variation in reinforcer amount than to variation in reinforcer delay in a procedure in which the reinforcer delay associated with the self-control alternative was adjusted until each macaque was indifferent between the two alternatives. Both experiments indicated that, in laboratory paradigms in which humans show self-control and pigeons and rats show impulsiveness, macaques show self-control. These results are inconsistent with the hypothesis that species differences in self-control are a function of language ability or of specific types of prior training. The results are consistent with the hypothesis that species differences in self-control are related to the ratio of brain size to body weight (a possible indicator of general cognitive ability) or to shared phylogeny. 相似文献
