Two experiments are reported using a visual familiarization categorization procedure. In both experiments, infants were familiarized with sets of stimuli previously shown to contain asymmetric feature distributions that support an asymmetry in young infants' categorization of cats and dogs (i.e. infants' cat category excludes dogs but their dog…

This issue of "Bilingualism: Language and Cognition" is about convergence, a type of language change that is contact-induced and results in greater similarity between two languages that are in contact with each other. In Backus (forthcoming), I have attempted an overview of contact-induced language change, focusing on causal factors, on mechanisms…

Does function facilitate categorization by focusing infants' attention generally on all commonalities among objects or specifically on functionally relevant properties? After familiarization to a novel category, 18-month-olds selected another category member from a pair of previously unseen test objects. In Experiments 1 and 2, infants chose…

The present research was aimed to reply and extend several recent findings showing qualitatively different behavioral effects produced by words perceived with vs. without awareness. Participants made a semantic categorization task on a target that was preceded by a prime word belonging either to the same (20% of trials) or to a different category…

Sensing that their libraries are in competition with local bookstores that offer leisurely atmospheres, warm aromatic drinks, and prominently displayed books and other materials by genre, many librarians have considered "shelving" the Dewey decimal system in order to rearrange their libraries in a similar fashion. The author of this article, a…

One attempt to make scores from large-scale assessments more interpretable has been to provide proficiency level scores to describe the meaning of student performance on tests. This study has examined the accuracy of Ercikan and Julian's (2002) guidelines for developing proficiency level scores and the classification accuracy of proficiency level…

In this paper, we present a data-based user modeling framework that uses both unsupervised and supervised classification to build student models for exploratory learning environments. We apply the framework to build student models for two different learning environments and using two different data sources (logged interface and eye-tracking data).…

The aim of this study is to investigate the act of apologizing with subjects from two different levels of English proficiency to find out whether there are similarities and differences between these groups and whether they approach native speaker apology norms. 20 subjects in intermediate level, 20 subjects in advanced level and 5 native speakers…

This book is for community leaders, librarians, library committees, volunteers, aid workers and others who are interested in the practical aspect of starting and maintaining a successful library.

The purpose of this study was to investigate the perceptions of school psychology practitioners regarding Asperger's Disorder, focusing on practitioner perceptions of self-competence, conceptualization of the clinical characteristics of the disorder, and how Asperger's Disorder is conceptualized for the purpose of determining special education…

This document covers the data terms used in the "VET in Schools, 2007" report. The primary purpose of this document is to help users of the report understand the specific data terms used in it. Terms that appear in the report are listed in alphabetical order with the following information provided for each: (1) Definition: a brief…

This study investigates the relationships between the use of a zoom tool, the terms they supply to describe the image, and the type of image being viewed. Participants were assigned to two groups, one with access to the tool and one without, and were asked to supply terms to describe forty images, divided into four categories: landscape, portrait,…

A report of preliminary findings and analysis from student discussion groups held on 7 U.S. campuses in Fall 2008, as part of Project Information Literacy. Qualitative data from discussions with higher education students across the country suggest that conducting research is particularly challenging. Students' greatest challenges are related to…

This action research combined qualitative and quantitative techniques to investigate two different types of writing assignments in an introductory undergraduate statistics course. The assignments were written in response to the same set of prompts but in two different ways: homework journal assignments or initial posts to a computer discussion…

Purpose: A factor largely overlooked amid the press for greater security in schools is the extent to which law enforcement participates in search and seizure and the implications such actions carry for student civil liberties. As case law suggests, police engaged in school searches may be held to the probable cause standard or the more flexible…
