A rose by any other name is not the same: the role of orthographic knowledge in homophone confusion errors

Homophone confusion errors were examined in a series of 6 experiments. Across a variety of tasks, readers consistently made more errors on homophone trials than on control trials. These effects were established in Experiment 1 using a semantic-decision task in which participants judged whether pairs of words were related or unrelated. For both related and unrelated trials, error rates were higher for homophones as compared with controls. Results such as these have previously been taken as evidence for the role of phonology in lexical access and reading. However, differences in orthographic knowledge (more specifically, knowledge of spelling-to-meaning correspondences) across participants and homophone items significantly predicted homophone errors across all tasks. In addition, spelling tasks and multiple-choice questionnaires revealed differences in orthographic knowledge across participants and homophone items. Although these results do not rule out a role for phonology in lexical access, they indicate that homophone confusion errors may also be due to factors other than phonology.

Influence of body dissatisfaction on 1-year change in nutrient intake of overweight and obese inner-city African American children

This analysis aimed to examine the relationship of baseline body dissatisfaction with 1-year change in nutrient intake of inner-city, overweight and obese, African American children. This is a secondary analysis of 1-year pre-post data available for a convenience sample of 88 children. After adjusting for baseline intake of dietary variables and intervention group status, baseline body dissatisfaction was associated with 1-year increases in intake of energy, and all macronutrients in girls, but not in boys. These relationships were not substantially altered after adjusting for baseline BMIz and global self-worth. After including all adjustment factors, increasing baseline body dissatisfaction in girls was associated with 1-year increased intake of total energy, total sugars, total fat, discretionary fat, and total carbohydrates. This analysis suggests that, in girls but not necessarily in boys, body dissatisfaction might need to be targeted during interventions that aim to improve nutrient intake.     

Relating inter-individual differences in metacognitive performance on different perceptual tasks

Human behavior depends on the ability to effectively introspect about our performance. For simple perceptual decisions, this introspective or metacognitive ability varies substantially across individuals and is correlated with the structure of focal areas in prefrontal cortex. This raises the possibility that the ability to introspect about different perceptual decisions might be mediated by a common cognitive process. To test this hypothesis, we examined whether inter-individual differences in metacognitive ability were correlated across two different perceptual tasks where individuals made judgments about different and unrelated visual stimulus properties. We found that inter-individual differences were strongly correlated between the two tasks for metacognitive ability but not objective performance. Such stability of an individual’s metacognitive ability across different perceptual tasks indicates a general mechanism supporting metacognition independent of the specific task.     

医疗纠纷处理中若干伦理问题的思考

医疗纠纷的增势和处理难已成为众所周知的事实。但是,在医疗纠纷处理中存在着医患关系的信任性、医疗事故鉴定的公正性和经济裣的合理笥是思考的伦理问题。只要医患双方、乃至社会对诸如医疗行为是否等同于一般的服务行为、病人权益是否等同于消费者权益、医疗事故鉴定是不是医医相护、经济裣能不能实行等价赔偿原则、医疗差错要不要给予经济补偿等有效为统一的认识,就会有利于医疗纠纷的处理,有利于维护医患双方的合法权益,有利     

Opening the Black Box: Using Process Evaluation Measures to Assess Implementation and Theory Building

The past decade has seen increasing recognition in prevention science of the need to move away from a black box approach to intervention evaluation and toward an approach that can elaborate on the mechanisms through which changes in the outcomes operate (Chen & Rossi, 1989; Durlak & Wells, 1997; Spoth et al., 1995). An approach that examines issues of program implementation is particularly critical in the design of efficacy studies of school-based preventive interventions. Numerous preventive intervention strategies are now delivered within the schools, often by regular classroom teachers. The extent to which teachers faithfully deliver a particular curriculum or incorporate instructional strategies emphasized by an intervention is a critical question for the overall project evaluation. This article illustrates the utilization of process measures from a multicomponent school-based prevention program to examine implementation of a teaching staff development intervention, and the program's underlying theoretical basis. Given the nested study design, the analyses utilize hierarchical linear models (Bryk & Raudenbush, 1992) to examine changes in teaching strategies by condition and investigate the hypothesized relationships between teaching practices and student behaviors based on the program's theoretical framework. Results suggest that teaching practices in two of the six intervention focus areas were positively impacted in the first 18 months of the project. Findings also support th relationships between teachers' instructional practices and students' behaviour.
