Retention of conditioned autonomic and behavioral responses in preweanling rats: Forgetting and reinstatement

Preweanling rats, 16 days of age, responded to an olfactory conditioned stimulus (CS) paired with a shock unconditioned stimulus (US) with increases in heart rate and behavioral activation. In two experiments this finding was replicated and, in addition, it was found that the form of these conditioned responses (CRs) changed after a retention interval. When tested 24 h after CS-US pairings, the subjects displayed a decrease in heart rate accompanied by CS-elicited freezing. Giving two unsignaled shocks prior to the delayed test effectively reinstated the tachycardia and behavioral arousal CRs. The results are discussed in terms of contextual influences on the form of the CR and how changes in the magnitude of context fear may alter responding to an olfactory CS.     

A conceptual level matching model for coordinating learner characteristics with educational approaches

The theoretical background and construct validity of Conceptual Level (CL) are summarized in order to provide the basis for deriving the CL matching model. The rationale for the CL matching model, which coordinates learner CL and degree of structure of educational approach, is described, and empirical support reviewed. A possible extension of the matching model based on coordinating learner “accessibility channels” with the form of presentation is summarized. Finally, a few problems in implementing matching models are noted.     

Formative Automated Computer Testing (FACT)

This study describes the context for the development of a tool to formatively assess information technology skills of students. The tool provides a reliable and valid assessment of word processing competency, utilizing automation to apply the test instrument via the Microsoft Office package. Tests can be designed directly by tutors, and delivered via a network. Evaluation of the tests suggests that immediate automated testing is preferred by students compared to a traditional written test. There is evidence that the tool improves the IT skills of its users, whereas a traditional written test has no such beneficial effect.     

Empowering parents of pre-school children

This paper describes a project undertaken with parents from an inner city primary school in Hartlepool, England. The main objectives of the project were to increase the self esteem of the parents, to give them an understanding of the pre-school curriculum and to enable them to develop their skills, knowledge and confidence to become involved in school life and to take ownership of their own children's education. The project focused around the production of a video to show nursery life in the school and this production was used as a vehicle to encourage the fulfilment of the objectives described above. The paper concludes by describing the successful outcomes of the project. Some of the outcomes were planned for, but we were equally delighted with the unexpected ones.     

Improving children's working memory and classroom performance

Previous research has demonstrated close relationships between working memory and children's scholastic attainment. The aim of the present study was to explore a method of improving working memory, using memory strategy training. Two hundred and fifty‐four children aged five to eight years were tested on measures of the phonological loop, visuo‐spatial sketchpad and central executive components of the multiple component model of working memory. Subgroups of children also completed tasks of following instructions and mental arithmetic in the classroom, and standardised tests of reading, arithmetic and mathematics. Half of the children then used Memory Booster, a computer game that teaches memory strategies, over a period of six to eight weeks. All the children were then retested on the memory and ability measures. The standardised tests were also administered five months later. The results revealed that working memory strategy training resulted in significant improvements in tasks assessing the phonological loop and central executive components of working memory, and tasks assessing following instructions and mental arithmetic in the classroom. However, no improvements were observed on standardised tests of reading, arithmetic or mathematics, either immediately following training or five months later. The results are discussed in terms of implications for educational practice.     

The Health Risks of Doping during the Cold War: A Comparative Analysis of the Two Sides of the Iron Curtain

This article compares East Germany's Cold War-era approach to doping to that of the USA's in terms of their respective impacts on medical risk. Although deserving of criticism on many levels, the GDR doping programme featured a number of safeguards designed to minimise medical dangers. Unlike their East German counterparts, American governmental units were not directly involved in the administration of performance-enhancing substances. The US approach to doping was not ideal in terms of medical risk, however. As a result of the country's regulatory approach to doping, the country's athletes frequently turned to black market sources for doping agents. It was also relatively common for American athletes to use performance-enhancing drugs without the benefit of medical supervision. The US approach to doping was in these ways inferior to that of East Germany's on the subject of medical risk.
