Behavioral momentum theory provides a framework for understanding how conditions of reinforcement influence instrumental response strength under conditions of disruption (i.e., resistance to change). The present experiment examined resistance to change of divided-attention performance when different overall probabilities of reinforcement were arranged across two components of a multiple schedule. Pigeons responded in a delayed-matching-to-sample procedure with compound samples (color + line orientation) and element comparisons (two colors or two line orientations). Reinforcement ratios of 1:9, 1:1, and 9:1 for accurate matches on the two types of comparison trials were examined across conditions using reinforcement probabilities (color/lines) of .9/.1, .5/.5, and .1/.9 in the rich component and .18/.02, .1/.1, and .02/.18 in the lean component. Relative accuracy with color and line comparisons was an orderly function of relative reinforcement, but this relation did not depend on the overall rate of reinforcement between components. The resistance to change of divided-attention performance was greater for both trial types in the rich component with presession feeding and extinction, but not with decreases in sample duration. These findings suggest promise for the applicability of quantitative models of operant behavior to divided-attention performance, but they highlight the need to further explore conditions impacting the resistance to change of attending. 相似文献

Interpersonal relationships constitute the foundation on which human society is based. The infant-caregiver bond is the earliest and most influential of these relationships. Driven by evolutionary pressure for survival, parents feel compelled to provide care to their biological offspring. However, compassion for non-kin is also ubiquitous in human societies, motivating individuals to suppress their own self-interests to promote the well-being of non-kin members of the society. We argue that the process of early kinship-selective parental care provides the foundation for non-exclusive altruism via the activation of a general Caregiving System that regulates compassion in any of its forms. We propose a tripartite structure of this system that includes (1) the perception of need in another, (2) a caring motivational or feeling state, and (3) the delivery of a helping response to the individual in need. Findings from human and animal research point to specific neurobiological mechanisms including activation of the insula and the secretion of oxytocin that support the adaptive functioning of this Caregiving System. 相似文献

With the sub‐title “Young people, the internet, and civic participation”, The civic web recognises that youngsters are now well along the path to fully and seamlessly integrated offline and online lives. How can we ensure these young people become and remain fully engaged in their wider society and worlds now and throughout their lifetimes? It applies to teachers insofar as “digital media are part of the taken‐for‐granted social and cultural fabric of learning, play, and social communication”. There is some relevance to formal learning technology here, but the recommendation is that you borrow a copy for thought‐provoking “spare‐time” reading. Eric Deeson 相似文献

This invaluable little product is a freely available “manual for streaming audio on the web”. The context of its origin is the growing use in India of internet‐based community radio, and of the use of that for educational and training purposes. Tested in a CoL workshop, the manual provides a wealth of generally accessible advice and guidance for setting up such radio stations / web channels and the dvd contains the manual and the (free and open source) software needed. If the concept of this package is likely to be of interest, get a copy—you'll find it fascinating! Eric Deeson 相似文献

This paper presents a conceptual analysis for students’ images of graphs and their extension to graphs of two-variable functions. We use the conceptual analysis, based on quantitative and covariational reasoning, to construct a hypothetical learning trajectory (HLT) for how students might generalize their understanding of graphs of one-variable functions to graphs of two-variable functions. To evaluate the viability of this learning trajectory, we use data from two teaching experiments based on tasks intended to support development of the schemes in the HLT. We focus on the schemes that two students developed in these teaching experiments and discuss their relationship to the original HLT. We close by considering the role of covariational reasoning in generalization, consider other ways in which students might come to conceptualize graphs of two-variable functions, and discuss implications for instruction. 相似文献

The funding environment has a profound impact on researchers’ behavior. In particular, it influences their freedom and readiness to conduct research ventures with highly uncertain outcomes. In this conceptual paper, we propose a concise new methodology to evaluate researchers’ risk aversion based on citation statistics. The derived single-number criterion PR is sensitive to the ratio of high impact versus average impact work, based on citation counts. We demonstrate the usefulness of PR on a micro and meso level in the field of chemistry. PR is a potentially valuable tool for managers in higher education, to control for the impact of their funding instruments. The conducted testing may, in addition, contribute to the literature stream dealing with the effects of peer review in the allocation of research funding. Our results support the view that peer review fosters mainstream research. However, faculties with the highest percentages of third-party funding may find ways to avoid the restrictive effects. We also find evidence that permanent positions back risky research endeavors. 相似文献

We analysed word reading and spelling in French adults with low levels of literacy (A‐IL). As well as examining phonological and lexical processes, we explored the relationship between literacy and oral language skills. Fifty‐two adult literacy students were compared with reading level‐matched pupils in Years 1–3 of primary school on reading tasks (pseudoword reading, word reading, text comprehension), spelling tasks (pseudoword spelling, text dictation) and oral language tasks. A‐IL scored the same as children on word reading and spelling but less well on pseudoword reading and spelling. They also produced fewer phonologically acceptable errors in the dictation. Regarding oral language skills, as a group A‐IL encountered greater difficulty in phonology than in morphosyntax and semantics, and correlations revealed strong relationships between literacy levels and oral skills, particularly in the domain of phonology. Within their group, however, A‐IL displayed several distinct language profiles. These could reflect different risk factors leading to functional illiteracy and are discussed regarding the cognitive and environmental causes of impaired reading acquisition. 相似文献

The purpose of this study was to use the Stages of Concerns (SoC) framework established by Hall and Loucks as a way to usefully identify types of teachers. Teachers who participated in the study were attending a professional development program called Great Expectations (GE). A modified version of the SoC questionnaire was used, so an exploratory factor analysis (EFA) of the modified questionnaire was conducted and identified a five factor structure. Using these five factors, a latent profile analysis was conducted to identify teachers. Three types of teachers emerged: enthusiastic teachers, teachers who were uninterested in the GE program, and teachers who were interested in the program but still had trepidations. These three groups were then compared on their emotions prior to the beginning of the GE program and their experience with GE. The quantitative results from this study are compared to qualitative results from previous research on teachers' SoC. 相似文献

Drawing on in-depth interviews with 15 openly bisexual male youth from sixth forms across the UK, this article documents positive experiences of bisexual male youth in school: participants had positive coming out experiences and did not encounter significant discrimination or harassment because of their sexual identity. Participants attribute this to the inclusive environments of their schools and local cultures. Examining the narratives of two participants who had negative experiences, this article also highlights continued issues for bisexual youth in schools. It thus advances our understanding of contemporary bisexual lives in educational institutions, and contributes to debates about whether sixth forms are more inclusive spaces than secondary schools for bisexuals. 相似文献
