Purpose: To examine when and how socially conditioned distinct speaking styles emerge in typically developing preschool children's speech. Method: Thirty preschool children, ages 3, 4, and 5 years old, produced target monosyllabic words with monophthongal vowels in different social-functional contexts designed to elicit clear and casual speaking…

In this article, the author gives an autobiographical account of his learning experiences and the lessons he learned from his lecturers. The author learned what he subsequently found is supported by experience and research, that the informal is as necessary as the formal. He also learned that teachers and students need to interact spontaneously,…

The authors of the current study examined the relationships among item-recognition, source-recognition, free recall, and other memory and cognitive ability tasks via an individual differences analysis. Two independent sources of variance contributed to item-recognition and source-recognition performance, and these two constructs related…

Growth mixture modeling (GMM) is a method for identifying multiple unobserved sub-populations, describing longitudinal change within each unobserved sub-population, and examining differences in change among unobserved sub-populations. We provide a practical primer that may be useful for researchers beginning to incorporate GMM analysis into their…

Baseline electroencephalogram (EEG) data were collected from twenty-nine 4-year-old children who also completed batteries of representational theory-of-mind (RTM) tasks and executive functioning (EF) tasks. Neural sources of children's EEG alpha (6-9 Hz) were estimated and analyzed to determine whether individual differences in regional EEG alpha…

Background: This study assessed whether Rural Health Clinics (RHCs) were associated with higher rates of recommended primary care services for adult beneficiaries diagnosed with diabetes in Oregon's Medicaid program, the Oregon Health Plan (OHP). Methods: OHP claims data from 2002 to 2003 were used to assess quality of diabetic care for…

The current study is part of a larger study that focused on within-group classroom discourse patterns of children in special education classes for language impairment (LI). Eleven children with LI aged 7-9 were examined across 4 classroom contexts: dialogic journal-writing, group lesson, peer play and sharing time. Amount and complexity of…

Perceptual training was employed to characterize individual differences in non-native speech sound learning. Fifty-nine adult English speakers were trained to distinguish the Hindi dental-retroflex contrast, as well as a tonal pitch contrast. Training resulted in overall group improvement in the ability to identify and to discriminate the phonetic…

The purpose of this study is to examine a process model of L2 learners' motivation. To investigate the overall process of motivation, the motivation of 148 university students was analyzed. Data were collected on three variables from the pre-decisional phase of motivation (i.e., value, expectancy, and intention) and four variables from the…

In this event-related brain potential (ERP) study, we examined how semantic and referential aspects of anaphoric noun phrase resolution interact during discourse comprehension. We used a full factorial design that crossed referential ambiguity with semantic incoherence. Ambiguous anaphors elicited a sustained negative shift (Nref effect), and…

For many decades, tool use has been viewed primarily as a cognitive achievement, an ability that separates not only adults and older children from infants, but humans from virtually all other species. According to this standard account, tool use and associated means-ends behaviors are dependent on symbolic or representational thinking. Organisms…

Previous studies have shown that a predominant tendency in creative generation tasks is to base new ideas on well-known, specific instances of previous ideas (e.g., basing ideas for imaginary aliens on dogs, cats or bears). However, a substantial minority of individuals has been shown to adopt more abstract approaches to the task and to develop…

The authors developed this experiential exercise to aid students in learning how others perceive them as well as how they perceive others and, ultimately, to begin to help them identify the origins of such perceptions. The exercise's goal is to explore how participants may make inaccurate perceptions of others and how they might pierce through…

This longitudinal study uses an ecological framework to examine school and individual influences on academic achievement among African American and Latino students with and without disabilities who had recently transferred to more inclusive schools. The authors' ecological framework includes four domains: organizational policies and practices,…

This article addresses the question of what language proficiency (LP) is, both theoretically and empirically. It does so by making a distinction, on one hand, between "basic" and "higher language cognition" and, on the other hand, between "core" and "peripheral components" of LP. The article furthermore critically examines the notion of "level" in…
