Visual statistical learning in children with and without DLD and its relation to literacy in children with DLD

Reading and Writing - Visual statistical learning (VSL) has been proposed to underlie literacy development in typically developing (TD) children. A deficit in VSL may thus contribute to the...     

Food sharing in albino rat pups: Does familiarity breed contempt?

The present experiment investigated the effects of kinship and familiarity upon food sharing in pairs of albino rat pups. Five pairs of rats from each of the following groups were tested: (1) familiar siblings, (2) nonfamiliar siblings, (3) familiar nonsiblings, and (4) nonfamiliar non-siblings. A small food portion was used, necessitating not only close physical contact, but also cooperation in the sense that both pups were required to remain relatively immobile in order for both to feed simultaneously. Results indicated more frequent sharing among unfamiliar pups, whether related or not. Results also indicated that food sharing increased in frequency among all four groups over the 5-day testing period, suggesting that cooperation in the form of food sharing can develop, or increase in frequency, over time in albino rat pups.     

Grade Level and Gender Differences in the Writing Self-Beliefs of Middle School Students

The objectives of this study were to determine whether middle school students' writing self-efficacy beliefs make an independent contribution to the prediction of their writing competence and to explore grade level and gender differences in writing self-beliefs (N = 742). Writing self-efficacy was the only motivation construct to predict writing competence in a model that included writing self-concept, writing apprehension, perceived value of writing, self-efficacy for self-regulation, previous writing achievement, gender, and grade level. Girls were more competent writers than were boys, but there were no gender differences in writing self-efficacy beliefs. However, when students were asked whether they were better writers than their peers, girls expressed that they were better writers than were other boys or girls in their class or in their school to a greater degree than did the boys. These findings suggest that girls and boys may use a different metric when responding to traditional self-efficacy scales. Students in Grade 6 reported higher self-efficacy and found writing more valuable than did their older peers, and students in Grade 7 reported lower writing self-beliefs than did students in Grades 6 or 8.     

Examining the Double-Deficit Hypothesis in an Orthographically Consistent Language

As many of you know, this is my final issue as editor of Scientific Studies of Reading. The new editor, Charles Hulme, has the work well in hand and has actually completed the editing of two articles which appeared in Issue 3 of this volume. The journal will be in good hands. I want to thank the many board members, reviewers, and authors for their energy, talents, and enthusiasm in the cause of advancing the journal. It's been a great privilege to be able to work with you and to guide the journal for 5 years. The current issue is a special issue, which had its inception in an idea of Mike Pressley's to have authors assess the present and future of key areas of literacy research. The first three articles in this issue are part of the special issue. The fourth article is a rewritten version of Charles Perfetti's Distinguished Scientific Contribution presentation at the July 2006 SSSR meeting. I append comments about Mike Pressley, written by Joanna Williams, who appropriately was the first editor of Scientific Studies of Reading and who had a hand in this special issue.     

METAPHORS AS KEYS TO CREATIVE THINKING

Metaphors can be seen as analogies which explain new or complex ideas. A good metaphor is enriching and says more than a logical explanation. In creative thinking metaphors are also used to generate ideas. This may be done consciously–as in synectics–or unconsciously, as in hypnosis. A more inclusive way of looking at metaphors is to see them as a part of everyday speech which affects the ways in which people perceive, think and act. Realities and problems are defined by metaphors, although people might not be aware of this, in the same way as fishes learn about the importance of water only if they get out of it. It is possible to speak of a theory of metaphors in creative thinking and problem solving.     

Assumptions Underlying Performance-Based Budgeting

Interest in performance budgeting is growing despite a lack of research on its effectiveness. U.S. states have largely used incremental and formula budgeting processes to fund higher education. However, more than half of them are experimenting with some form of performance budgeting. There have been similar attempts to reform budget practices in the U.S. in the past, but most of these processes have been largely abandoned. Governmental performance budgeting for higher education assumes policy objectives are stable, complex decisions on budget trade-offs can be made at governmental levels on the basis of data, institutions operate as bureaucracies, resources can be linked to outcomes, outcomes are identifiable and can be agreed upon, accountability can be achieved through budget policies, and current practices create incentives to enrol unqualified students. These assumptions are not realistic. Consequently, performance budgeting will not meet proponents expectations and will suffer the fate of past budget fads.     

A theoretical note on concepts and the need for Cyclic Concept Maps

This article examines concepts and propositions from a theoretical perspective, and establishes the need for and develops an extension to Concept Maps (CMaps), called Cyclic Concept Maps (Cyclic CMaps). Cyclic CMaps are considered to be an appropriate tool for representing knowledge of functional or dynamical relationships between concepts. CMaps, on the other hand, are viewed as an appropriate tool for representing hierarchic or static knowledge. The two maps complement each other and collectively capture a larger domain of knowledge, thus forming a more effective knowledge representation tool. © 2005 Wiley Periodicals, Inc.

White Paper: functionality and efficacy of wrist protectors in snowboarding—towards a harmonized international standard

The wrist is the most frequently injured body region among snowboarders. Studies have shown that the risk of sustaining a wrist injury can be reduced by wearing wrist protection. Currently, there are a wide variety of wrist protection products for snowboarding on the market that offer a range of protective features. However, there are no minimum performance standards for snowboarding wrist protectors worldwide. The International Society for Skiing Safety convened a task force to develop a White Paper to evaluate the importance and necessity of a minimum performance for all wrist protectors used in snowboarding. The White Paper outlines the need for a general framework for a harmonized international standard and reviews the existing evidence. Therefore, this White Paper may serve as a common base for future discussions. The broader goal of developing and implementing such a standard is to reduce the incidence and the severity of wrist injuries in snowboarding without increasing the risk of adverse events, such as upper arm or shoulder injury. The European standard for inline skating wrist protectors (EN 14120) can serve as a starting point for efforts related to a standard for snowboard wrist protectors, but certain modifications to the standard would be required. It is hypothesized that implementation of a snowboarding wrist protector standard would result in fewer and less severe wrist injuries in the sport and could translate into more riding days for healthy snowboarders and significant health-care costs savings.
