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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献
