Purpose: This study's main purpose was to (a) identify acoustic signatures of hypokinetic dysarthria (HKD) that are robust to phonetic variation in conversational speech and (b) determine specific characteristics of the variability associated with HKD. Method: Twenty healthy control (HC) participants and 20 participants with HKD associated with…

The purpose of this study was to assess to what extent specific reading disabilities and poor phonologic processing in children who read Hebrew, a primarily consonant orthography, are related to central auditory temporal processing deficits (TPDs). Twenty-four Hebrew-speaking children (ages 10-13) with and without reading disabilities were asked…

Using the Luck and Vogel change detection paradigm, we sought to investigate the capacity of visual working memory in 5-, 7-, and 10-year-olds. We found that performance on the task improved significantly with age and also obtained evidence that the capacity of visual working memory approximately doubles between 5 and 10 years of age, where it…

The teaching of human anatomy has had to respond to significant changes in medical curricula, and it behooves anatomists to devise alternative strategies to effectively facilitate learning of the discipline by medical students in an integrated, applied, relevant, and contextual framework. In many medical schools, the lack of cadaver dissection as…

This study tests the claim that word learning and retention in a second language are contingent upon a task's involvement load (i.e. the amount of need, search, and evaluation it imposes), as proposed by Laufer and Hulstijn (2001). Seventy-nine beginning learners of Spanish completed one of three vocabulary learning tasks that varied in the amount…

Background: Boys with early onset of conduct disorder (CD), most of whom also meet diagnostic criteria of a comorbid attention deficit hyperactivity disorder (ADHD), tend to exhibit high levels of aggression throughout development. While a number of functional neuroimaging studies on emotional processing have been performed in antisocial adults,…

The merits of recasts have been widely debated and investigated in and out of the language classroom. This quasi-experimental study examines the impact of recasts in comparison to prompts and no corrective feedback on francophone learners' acquisition of English third person possessive determiners. Sixty-four students from three intact intensive…

We applied a mixed-method research design to investigate the patterns of reasoning used by novice undergraduate chemistry students to classify chemical substances as elements, compounds, or mixtures based on their particulate representations. We were interested in the identification of the representational features that students use to build a…

Background: Self-handicapping is an attribution-related process whereby individuals create performance impediments/excuses to protect self-worth in socially evaluative environments. Thus, the prevailing motivational climate would appear to be an important factor when attempting to understand the situational self-handicapping process within school…

Regardless of the extremely subtle acoustic changes that are perceptible within almost all perception research studies, it is the total overall effect that generally occupies each individual listener. A long line of research indicates that many subtle "music changes" are often not perceived accurately and are actually mistakenly identified.…

Overview: Behavioural data reveal an inverted U-shaped function in the efficiency of prospective memory from childhood to young adulthood to later adulthood. However, prior research has not directly compared processes contributing to age-related variation in prospective memory across the lifespan, hence it is unclear whether the same factors…

The purposes of this study are to test whether the processing of subject relative (SR) clauses is easier than that of object relative (OR) clauses in Turkish and to investigate whether the comprehension of SRs can be better explained by the linear distance hypothesis or structural distance hypothesis (SDH). The question is examined in two groups…

Purpose: Today's technology supports the design of more and more sophisticated interactive learning environments. This paper aims to argue that such design should develop from first principles. Design/methodology/approach: In the paper by first principles is meant: learning theory and principles of course design. These principles are briefly…

Fostering student teachers' confidence and competence to teach science in early childhood settings is a complex and challenging task for teacher educators situated in university classrooms. The research reported in this paper is based on an analysis of 3rd-year early childhood student teachers' assignments. The assignment required them to…

Student motivation within the classrooms is a widely recognized problem and will remain so in the foreseeable future. Literature suggests that students' motivation for learning and performance can be enhanced by creating an appropriate classroom environment, which is again determined by the design of various structural characteristics of a course,…
