Few autistic brain samples are available for study, limiting investigations into molecular and histopathological abnormalities associated with this common disease. To facilitate distribution of samples, we have constructed a tissue array containing cerebral and cerebellar cores from 5 autistic children, 1 girl with Rett syndrome, and 5 age-matched…

The present study examines private speech and strategy-use patterns for solving simple number fact problems in addition. The progressive differentiation by grade between children's levels of private speech internalization--including silence--was investigated and related to children's developmental patterns for subcategories of strategy-use…

This article provides a methodological illustration of how to conduct scientifically rigorous secondary interventions within the context of three-tiered models of support. Specifically, the authors demonstrate one approach for using schoolwide data to identify middle school students (N = 65) with both academic and behavioral concerns. Then, they…

Field investigations are not characterized by randomized and manipulated control group experiments; however, most school science and high-stakes tests recognize only this paradigm of investigation. Scientists in astronomy, genetics, field biology, oceanography, geology, and meteorology routinely select naturally occurring events and conditions and…

All animals must make choices regarding what foods to eat, where to eat, and how much time to spend feeding. Optimal foraging theory explains these behaviors in terms of costs and benefits. This laboratory exercise focuses on optimal foraging theory by investigating the winter feeding behavior of birds on the goldenrod gall fly by comparing…

Describes and evaluates three different videoconferencing systems for supporting multiparty remote conversations. The systems differed by the number of participants visible at once, their spatial arrangement, and control over who was seen. These conversations were compared to same-room and audio-only conversations. Only the same-room condition…

This investigation compared the prevalence rates of pathological and problem gambling between Greek-affiliated and non-Greek-affiliated college students. The 954 participants volunteered to take the South Oaks Gambling Screen (SOGS; Lesieur & Blume, 1987), which measures gambling disorders. A statistically significant association was found between…

Recent studies have suggested that unusual visual processing in autism might stem from enhanced visual discrimination. Although there are also many anecdotal reports of auditory and tactile processing disturbances in autism these have received comparatively little attention. It is possible that the enhanced discrimination ability in vision in…

The purpose of this investigation was to test the age-related measurement invariance and temporal stability of the 13-item version of Antonovsky's Sense of Coherence Scale (SOC). Multigroup structural equation modeling of longitudinal data from the Canadian National Population Health Survey was used to examine the measurement invariance across 3…

In this article, the author developed an activity called "The Polar Insulation Investigation." This activity builds on students' natural interest in "things polar" and introduces them to animal adaptations in a unique way. The aim of the exploration is to determine the role of animal coverings (e.g., blubber, fur, and feathers) and to see which is…

A comparative study of the cost effectiveness of retrospective manual and on-line bibliographic searching is described. Individual task times for question analysis, searching, photocopying, shelving and output distribution were measured, and component costs for labor, information, reproduction, physical space and telecommunications calculated. The…

This study investigated the relative conformity of American and Brazilian students across ages from 9 to 21 years old. (Authors)

The purpose of this investigation was to evaluate a methodology for analyzing the interactive effects of two different antecedent variables on child noncompliance in an outpatient clinic. Phase 1 of this study consisted of antecedent manipulations to identify situations that occasioned problematic behaviors (i.e., presence or absence of the…

The core idea that we argued for in the target article was that grammatical processing in a second language (L2) is fundamentally different from grammatical processing in one's native (first) language (L1). Our major source of evidence for this claim comes from experimental psycholinguistic studies investigating morphological and syntactic…

Adult education and ICT (information and communication technology) are intrinsically linked and ICT infiltrates every part of our lives. As those who have grown up and been educated in the ICT age become more prominent in society those who were not find themselves with the distinct possibility of becoming second-class citizens if not so already.…
