Postinjection suppression of drinking is modified by the presence of conditioned contextual cues: Implications for both anticipatory and posttreatment nausea in humans

In three experiments, we set out to determine whether the response of rats to an injection of LiCl would be modified by the presence of an environmental context that had previously been paired with LiCl. Experiment 1 confirmed that one feature of the malaise produced by LiCl is a reduced tendency to consume an otherwise palatable flavor. Experiment 2 showed that the size of this response was enhanced if it was measured in the presence of a conditioned context. In Experiment 3, we investigated the possibility that the postinjection response could be modified by an overshadowing treatment given during the conditioning phase. The significance of these findings for the understanding of chemotherapyinduced nausea in the clinical population is discussed.     

Developing Symbolic Interpretation Through Literary Argumentation

Literature can be a powerful resource for adolescents’ psychosocial development, as it provides opportunities to experience the world through the perspectives of others and juxtapose these with one’s own experiences. However, gaining access to these perspectives requires going beyond literal words on the page to explore interpretive meanings. This mixed-methods case study addresses the need to better understand how adolescent students learn to interpret literary works. Specifically, 9th-grade students participated in a 5-week instructional module focused on symbolic interpretation and coming of age themes in texts with a variety of sources of complexity. The primary data sources were an intentional sample of classroom discussions and essays written before and after instruction. Analyses indicate that students learned to make interpretive claims around symbolism. Textual evidence to support these claims was evident in whole-class discussions but less so in the written essays. Students also struggled to reason about why evidence supported particular claims and how the interpretive claims were related to understanding the characters and their worlds. Discussion focuses on the value of symbolic interpretation as a starting point for engaging adolescents in interpretive practices but notes that developing facility with literary interpretation takes concerted effort over longer periods of time.     

Apparent hyperglycemic and hypoglycemic conditioned responses with exogenous insulin as the unconditioned stimulus

Rats were injected with either insulin or saline and placed in one of two distinctive environments for 25 min on each of several days. On test trials for conditioning, the animals were injected with saline in both environments and blood glucose levels were measured. Apparent conditioned changes were obtained, but the direction of the conditioned response depended upon the environment in which the animals were placed. A conditioned hyperglycemic response occurred in one environment, and a conditioned hypoglycemic response occurred in the other environment. This pattern occurred in both within-subject and between-subjects designs and was not influenced by route of insulin injection (ip or sc). The hypoglycemic, but not the hyperglycemic, response was blocked by methyl atropine. The occurrence of both CR patterns with the same low insulin dose is contrary to previous speculation that the different CR patterns are due to different dose levels of insulin.     

An arts project failed,censored or … ? A critical incident approach to artist–school partnerships

When a successful primary school engaged a writer to work with children on an arts project, the teachers and the writer thought that the result would be a lively, publishable product. When the writer worked with the children, he thought that he should use the children's experiences and ideas as a basis for meaningful and engaged composition. However, the result was a text which the head‐teacher and her staff felt was inappropriate. They were concerned that it could bring disapproval from parents and possible adverse publicity. The head refused to publish but continues to worry about this decision. The writer describes the project as censored. In this paper, we suggest that this critical incident raises important questions about the nature of ‘partnership’ between artists and schools and the role of the flagship Creative Partnerships policy and programme. We suggest some possibilities for dealing with such situations in future and argue that Creative Partnerships must do more to promote dialogue about the critical role of the arts and artists in society.     

Support for assessment practice: developing the Assessment Design Decisions Framework

There are many excellent publications outlining features of assessment and feedback design in higher education. However, university educators often find these ideas challenging to realise in practice, as much of the literature focuses on institutional change rather than supporting academics. This paper describes the conceptual development of a practical framework designed to stimulate educators’ thinking when creating or modifying assessments. We explain the concepts that underpin this practical support, including the notions of ‘assessment decisions’ and ‘assessment design phases’, as informed by relevant literature and empirical data. We also present the outcome of this work. The Assessment Design Decisions Framework. This provides key considerations in six categories: purposes, contexts, tasks, interactions, feedback processes and learning outcomes. By tracing the development of the Framework, we highlight complex ways of thinking about assessment that are relevant to those who design and deliver assessment to tertiary students.     

AUTISTIC SPECTRUM DISORDERS AND ASIAN CHILDREN

ABSTRACT:  This paper compares the incidence of the diagnosis of Autistic Spectrum Disorders (ASD) among White and Asian children with reference to data obtained from thirteen local education authorities (LEAs) in England. It begins by outlining some of the theoretical debates associated with the definition, diagnosis and prevalence of ASD. The empirical component underpinning this work uses logistic modelling to ascertain whether the proportion of children with a statement of special educational need (SEN) for ASD is different for Asian and for White children and whether the proportion of children with a statement of SEN for ASD varies between LEAs. The discussion speculates as to possible reasons for the differences found and identifies areas for further research.     

The effect of a retention interval on habituation of the neophobic response

In three experiments, water-deprived rats were preexposed to a novel saccharin solution. The neophobic response to this flavor was then assessed in a choice test involving saccharin and water, administered either immediately or 24 h after preexposure. Subjects displayed a significantly greater preference for saccharin at the 24-h test than at the immediate test (Experiments 2 and 3). This “incubation” effect was eliminated if the subjects were more water-deprived at the delayed test than at the immediate test (Experiment 1), and enhanced if the amount of saccharin consumed during preexposure was increased (Experiment 3). Possible ways in which current theories of habituation might be amended in order to accommodate this finding are discussed.
