In two experiments, typically developing (TD) children, high-functioning children with autism (HFA) and children with a history of autism who have achieved optimal outcomes (OOs), matched on age (M = 13 years) and nonverbal IQ, were asked to extend properties of categories to new items (categorical induction). All groups demonstrated some…

We reject a trajectory approach to teaching that classifies "good" and "bad" teaching actions and seeks to move teachers' practices from one of these poles to the other. In this article we offer instead a conceptualisation of mathematics teaching actions as a "landscape of possibilities". We draw together terms…

Polytomous attributes, particularly those defined as part of the test development process, can provide additional diagnostic information. The present research proposes the polytomous generalized deterministic inputs, noisy, "and" gate (pG-DINA) model to accommodate such attributes. The pG-DINA model allows input from substantive experts…

This study reports results of a questionnaire of 210 counselor educators regarding assessment instruments covered in their assessment courses. Instruments are ranked on how extensively they are covered, and comparisons of coverage are made by assessment category (e.g., educational, clinical) and by instructor and program characteristic (e.g.,…

Introduction: Disciplinarity and other forms of differentiation in science have long been studied in the fields of science and technology studies, information science and scientometrics. However, it is not obvious whether these fields are building on each other's findings. Methods: An analysis is made of 609 articles on disciplinarity…

As part of our inquiry into how youth development and 4-H programming can affect the development of social capital for youth and for the community, we engaged youth in ripple mapping. Based on this information, we provide a typology of participation structures in youth development activities and the expected bridging and bonding social capital…

Background: The current functional models of disability do not adequately incorporate significant changes of the last three decades in our understanding of human functioning, and how the human functioning construct can be applied to clinical functions, professional practices and outcomes evaluation. Methods: The authors synthesise current…

Honoring "Teaching of Psychology" ("ToP") as it approaches its 40th anniversary, we extend prior overviews of its development and growth into 2012. We describe changes in editorial staff and journal organization, identify and describe the top 20 most frequent contributors to "ToP," and present the results of a content…

The objective of this research is to investigate students' mental models of the hailstone formation and explore factors that may affect their mental models. The sample chosen for the study was composed of a total of 84 students. The students attended the 1st to 4 th grade classes of the Social Studies Teaching Programme at Giresun University in…

Attentional capture is an unintentional shift of visuospatial attention to the location of a distractor that is either highly salient, or relevant to the current task set. The latter situation is referred to as contingent capture, in that the effect is contingent on a match between characteristics of the stimuli and the task-defined…

The World Health Organization's "International Classification of Diseases" ("ICD") is the most important diagnostic tool, worldwide, to ensure that people with intellectual and developmental disabilities receive the supports they need to live richer, fuller lives. And yet, the "ICD" has naming conventions that create a conundrum for the field,…

A multitude of models have been proposed to account for the neural mechanism of value integration and decision making in speeded decision tasks. While most of these models account for existing data, they largely disagree on a fundamental characteristic of the choice mechanism: independent versus different types of competitive processing. Five…

Social bookmarking systems allow people to create pointers to Web resources in a shared, Web-based environment. These services allow users to add free-text labels, or "tags", to their bookmarks as a way to organize resources for later recall. Ease-of-use, low cognitive barriers, and a lack of controlled vocabulary have allowed social…

Second language writing teachers face numerous challenges when providing feedback on student writing. There may be so many problems in the writing that is almost impossible for them to focus on or they may constantly seek a better method of giving feedback on student written errors. This paper attempts to provide second language writing teachers…

Micceri (1989) examined the distributional characteristics of 440 large-sample achievement and psychometric measures. All the distributions were found to be nonnormal at alpha = 0.01. Micceri indicated three factors that might contribute to a non-Gaussian error distribution in the population. The first factor is subpopulations within a target…
