Rats shocked once by a stationary, wire-wrapped prod mounted on the wall of the test chamber incorporated sand, wooden blocks, or commercial bedding material on the floor of the chamber into a defensive response. They moved the available material toward and over the shock prod in all three conditions, adapting the response topography to the particular demands of the available material. In the sand and bedding conditions, the rats buried the prod by pushing and spraying piles of the material with snout and forepaws, whereas, in the blocks condition they picked up the blocks with their teeth and placed them individually around the prod. In Experiment 2, the rats buried the shock prod with blocks even when they had to first carry the blocks to the prod from the back of the chamber. Thus, conditioned defensive burying is not a simple, reflexive response to objects paired with a painful stimulus: it is a complex behavioral sequence that can vary as a function of the availability of burying materials. 相似文献

Rats shocked once by a stationary, wire-wrapped prod bury it if suitable materials are available. Does this conditioned defensive burying occur when rats have the opportunity to flee from the source of aversive stimulation, or is it limited to situations such as those in which it had previously been studied—those in which the relatively small test chamber confined each rat to the immediate vicinity of the prod? In the present experiments, the capacity of rats to flee from the shock prod was enhanced by increasing the floor dimensions of the test chamber up to 200X80 cm (Experiment 1) or by providing the rats with an opportunity to seek refuge in a separate, safe compartment (Experiment 2). Although both of these modifications to the usual conditioned-defensive-burying paradigm significantly reduced the duration of burying and the height of the accumulated mounds, burying remained well above control levels in all experimental conditions. 相似文献

This paper explores some of the relationships between the understanding of gender equity and gender issues in education held by academic staff in an institute of higher education, and their views on the importance of incorporating gender into the curriculum. The paper discusses findings pertaining to how academics approach gender issues in their teaching in their relationships with students and with other members of staff. In so doing the question is raised—what messages are trainee teachers receiving about gender issues? The findings also discuss some of the pedagogical implications arising from the absence of theoretical perspectives or orientations in relation to gender in preservice teacher education. 相似文献

Resistance to interference was examined in rats that received a complex negative patterning discrimination in which XA and
XB were followed by food reinforcement and XAB was not. Retention of the discrimination was evident after separate reinforcement
of both A and B (Experiment 3), but not after reinforcement of either AB (Experiments 1 and 3) or XAB (Experiments 2 and 3).
These data suggest that complex negative patterning discriminations are acquired configurally and that the relative similarity
of the original discrimination and subsequent interference trials dictates the final degree of retention observed. 相似文献

Whilst peer observation of teaching is well established as a practice that can enhance teaching quality, the challenge to fully embed this practice in universities remains unresolved. This article analyses the perspectives of 18 university leaders (nine Australian and nine English) drawn from a range of school-based leaders to senior leaders of learning and teaching. Our study indicates that some of the challenges associated with leading such schemes can be mitigated through approaches to educational leadership that enact a respectful and collegiate ethos. This we suggest can support developmental academic engagement in peer observation for positive and lasting change. 相似文献

As the research literature on principals leading school turnaround grows, determining whether or not real differences between good, even effective, principals and turnaround principals becomes increasingly important. Recent federal government policy and investment established turnaround models that emphasize the role of the school principal, suggesting that turnaround principals do need to be different than other principals in some meaningful ways. But any difference in skill or characteristic remains undefined. For this article, we conducted a systematic review of empirical research literature to identify studies of principals who led successful school turnaround initiatives. We reviewed 18 empirical studies to categorize the education leadership areas in which turnaround principals must excel. We also present the limited evidence regarding attitudes, traits, or perspectives principals leading turnaround should likely possess. Finally, we consider implications of our findings for research and practice. 相似文献

In this article we address the current context of intensified racialized state securitization by tracing its roots to the naturalized colonial architectures of everyday modern life—which we present through the metaphor of “the house modernity built.” While contemporary crises are often perceived to derive from external threats to the house, we argue that in fact these crises are a product of the violent and unsustainable practices that are required in order to build and sustain the house itself. As the structural integrity of the house increasingly comes under strain, there are different possible responses, three of which we review here. We conclude by asking what kind of education might enable us to imagine and practice alternative formations of existence in a context where the house appears to be crumbling, and, indeed, has always been a fantasy. 相似文献
