Multiple coding strategies in the retention of musical tones by possessors of absolute pitch

Eighteen musicians with absolute pitch (AP) confirmed by screening tests participated in tonal and verbal short-term-retention tasks. In the tonal task, subjects identified three successive piano tones by their letter names. Recall of these note names after 18 sec of counting backwards was near perfect. Recall after an 18-sec delay filled with random piano tones was also near perfect. In contrast, the same subjects demonstrated significant forgetting when required to retain letter trigrams while counting backwards for 18 sec. These results were essentially replicated in a second experiment using longer (27 sec) retention intervals, a more demanding verbal interference task, and an active musical interference task (singing a descending scale). We interpret these results as indicating that retention of note names by possessors of AP is not limited to verbal encoding; rather, multiple codes (e.g., auditory, kinesthetic, and visual imagery) are probably used.     

A Monte Carlo study of the effects of correlated method variance in moderated multiple regression analysis

It has been suggested that hierarchical regression analysis provides an unambiguous conclusion with regard to the existence of moderator effects (Arnold & Evans, 1979). This paper examines the impact of correlated error among the dependent and independent variables in order to explore whether or not artificial interaction terms can be generated. A Monte Carlo study was performed to investigate the effects of correlated error on noninteraction and interaction models. The results are clear-cut. Artifactual interaction cannot be created; true interactions can be attentuated. Some practical suggestions are provided for drawing inferences from hierarchical regression analysis.     

THE THEOLOGICAL DEBATE OVER HUMAN ENHANCEMENT: AN EMPIRICAL CASE STUDY OF A MEDIATING ORGANIZATION

For most theologians, theology should ultimately be used by the laity and/or the public. However, the religion and science debate has not focused on the divide between theologians and the laity. In this case study I examine the debate among theologians about human enhancement. I focus on the extent to which the structure of the debate in a “mediating organization” between the theologians and the public coincides with the structure of the debate among the theologians. I conduct a survey of participants in the organization, and find that the basic divides among the theologians are largely replicated. These results, when combined with studies of the theologians themselves and the laity, provide a more holistic understanding of the future debate about human enhancement.     

Staff-patient relationships and outcomes in schizophrenia: the role of staff attributions

We investigated associations between staff-patient relationships and outcomes in a randomised controlled trial of motivational interventions for drug and alcohol misuse in schizophrenia. Participants were 204 patients and their care co-ordinators. We assessed relationship status (positive versus neutral) and staff attributions of control using Five Minute Speech Samples collected at baseline. We examined associations between this baseline data and symptoms at 12-months follow-up. We found that dyads with positive relationships at baseline had significantly less symptoms at 12-months compared to those dyads with neutral relationships. As predicted, care co-ordinators with positive relationships were less likely to attribute patients' problems as being within their control. The findings highlight the potentially important role of positive staff-patient relationships in outcomes. Our findings are also in line with the hypothesis that staff attributions may contribute to the development of more positive relationships.     

Everyday conceptions of object fall: explicit and tacit understanding during middle childhood

Adults make erroneous predictions about object fall despite recognizing when observed displays are correct or incorrect. Prediction requires explicit engagement with conceptual knowledge, whereas recognition can be achieved through tacit processing. Therefore, it has been suggested that the greater challenge imposed by explicit engagement leads to elements of conceptual understanding being omitted from prediction that are included in recognition. Acknowledging that research with children provides a significant context for exploring this "omission hypothesis" further, this article reports two studies with 6- to 10-year-olds, each of which used prediction and recognition tasks. Study 1 (N=137) focused on understanding of direction of fall, and Study 2 (N=133) addressed speed. Although performance on the recognition tasks was generally superior to performance on the prediction tasks, qualitative differences also emerged. These differences argue against interpreting explicit level understanding purely in terms of omission of tacit constructs, and the article outlines alternative models that may account for the data.

Developing a Prevention Synthesis and Translation System to Promote Science‐Based Approaches to Teen Pregnancy,HIV and STI Prevention

The Interactive Systems Framework for Dissemination and Implementation (ISF) is a multi‐system framework that can guide research‐to‐practice efforts by building and supporting the work of three interacting systems: the Prevention Delivery, Support, and Synthesis and Translation Systems. The Synthesis and Translation system is vital to bridging science and practice, yet how to develop it and train support system partners to use it is under‐researched. This article bridges this gap by offering a case example of the planning, development, and use of a synthesis and translation product called Promoting Science‐based Approaches to Teen Pregnancy Prevention using Getting To Outcomes. The case presented documents the process used for developing the synthesis and translation product, reports on efforts to engage the Prevention Support system to use the product, and how we approached building interaction between the Synthesis and Translation System and the Support System partners. Practice‐oriented evaluation data are also presented. Implications for practice, policy and research are discussed.
