Skilled readers were trained to recognise either the oral (n=44) or visual form (n=40) of a set of 32 novel words (oral and visual instantiation, respectively). Training involved learning the ‘meanings’ for the instantiated words and was followed by a visual lexical decision task in which the instantiated words were mixed with real English words and untrained pseudowords, and the instantiated words were to be considered as words. The phonology‐to‐orthography consistency (feedback consistency) of the instantiated words was manipulated to investigate the role of feedback from phonology in orthographic learning. Masked consonant and vowel‐preserving form primes were used in the lexical decision task as probes of orthographic learning. Feedback‐consistent instantiated words were recognised significantly faster in lexical decision than feedback‐inconsistent instantiated words, and facilitation was significantly greater from consonant‐preserving than vowel‐preserving primes for orally but not visually instantiated words. The results support the hypothesis that orthographic representations based on a consonant frame can be generated from the speech signal before encountering the printed forms, and that feedback from phonology is involved in the early stages of orthographic learning. 相似文献

Testosterone during Pregnancy and Gender Role Behavior of Preschool Children: A Longitudinal, Population Study 总被引:2,自引:1,他引:2

Levels of testosterone (T) and sex hormone–binding globulin (SHBG) were measured in blood samples from pregnant women and related to gender role behavior in 342 male and 337 female offspring at the age of 3.5 years. Gender role behavior was assessed using the Pre–School Activities Inventory, a standardized measure on which a parent indicates the child's involvement with sex–typical toys, games, and activities. Levels of T, but not SHBG, related linearly to gender role behavior in preschool girls. Neither hormone related to gender role behavior in boys. Other factors, including the presence of older brothers or sisters in the home, parental adherence to traditional sex roles, the presence of a male partner in the home, and maternal education, did not relate to gender role behavior in this sample and did not account for the relation observed between T and behavior. Although other, unmeasured factors may explain the relation, the results suggest that normal variability in T levels prenatally may contribute to the development of individual differences in the gender role behavior of preschool girls. 相似文献

AbstractThis paper offers a strategic initiative designed to boost the level of collaborative mathematical research involving undergraduate mathematics students at Butler University. It describes goals, program design, logistics, and outcomes for an 8-day intensive summer experience in which undergraduate mathematics majors engaged in original mathematical research at an introductory level. 相似文献

Participation in discussions about the public interest can be enhanced by technology, but can also create an environment in which participants are overwhelmed by the quantity, quality, and diversity of information and arguments. Political participation is at a greater disadvantage than non-political activities in that participants from different parties already start out with established differences, which requires them to reach some form of common ground before progress can be made. Those seeking authentic deliberation are discouraged to participate when confronted with uncivil and inflammatory rhetoric. These issues are often exacerbated in online discussions, where lack of identity cues and low barriers to entry can lead to heightened incivility between participants, often labeled as “flaming” and “trolling”. This paper explores the extent to which moderator systems, tools online discussion forums use to manage contributions, can reduce information overload and encourage civil conversations in virtual discussion spaces. Using the popular website Slashdot as an example of sound moderation in a public discourse setting, we found that users move toward consensus about which and how comments deserve to be moderated. Using these findings, we explore how transferable these systems are for participation in public matters specifically to the unique attributes of political discussion. Slashdot's political forum provides a comparison group that allowed us to find quantitative and qualitative differences in political posting, comments, and moderation. Our results show that large scale, civil participation is possible with a distributed moderation system that enables regularly lively debates to be conducted positively because the system provides tools for people to enforce norms of civility. 相似文献

Identification of core competencies for undergraduates in food safety is critical to assure courses and curricula are appropriate in maintaining a well‐qualified food safety workforce. The purpose of this study was to identify and refine core competencies relevant to postsecondary food safety education using a modified Delphi method. Twenty‐nine experts representing food safety professionals in academia, government, and industry were given 2 rounds of questionnaires that specified initial food safety competencies, core domains, and subdomains. Competencies were defined as a set of skills, knowledge, and abilities that correlate to success of a trainee. The framework for which competencies were classified consisted of (1) core domains, defined as broad food safety subjects; and (2) subdomains, or more specific food safety subjects. The expert panel used a 5‐point Likert scale with an acceptance criterion, or consensus, of 75%, with a rating of “4” or greater. After 2 rounds of questionnaires and revisions from the expert panel, 5 core domains were established: (1) Food Production, Manufacturing, Retail, and Consumer; (2) Foodborne Hazards; (3) Public Health; (4) Legislation and Policy; and (5) Communication and Education. Specific responses from the experts highlighted areas in which further curriculum revision would be beneficial. This study provides a framework for the development of a vetted, standardized undergraduate food safety curriculum. The Delphi method, with its inclusion of professionals representing various sectors of food safety, provided relevant perspectives for curriculum design, and also allowed participants the opportunity to contribute to the education of future food safety professionals. 相似文献

This paper reports on qualitative research from an Australian, K-6, faith-based school about teachers’ experience of a job-embedded professional learning initiative (the Whole-School Benchmarking of Writing, WSBoW) that was designed to improve teachers’ capacity to apply data-driven decision-making to achieve improvements in student learning. Teacher interviews provided the data about experiences and influences on teching practice. The findings demonstrated that the professional learning initiative provided teachers with a supportive pedagogical tool for focusing their teaching practices on improving student learning. A research based evaluative framework was used as a heuristic to analyse the change initiative. This study used the framework and employed a social constructivist and sociocultural epistemology that recognised the importance of leadership and school context in the development of a culture focused on collaborative communities of practice and data-driven teacher decision-making. The study has significance for leaders, schools and systems that engage teachers in professional capacity building. 相似文献
