This study examines the perfective past tense of Greek in an elicited production and an acceptability judgment task testing 35 adult native speakers and 154 children in six age groups (age range: 3;5 to 8;5) on both existing and novel verb stimuli. We found a striking contrast between sigmatic and non-sigmatic perfective past tense forms. Sigmatic…

Self-modeling can take different forms but is described as a process where one observes one's own successful behavior and learns from it without dependence on any particular medium. In this study, two separate experiments were conducted to evaluate a video self-modeling (VSM) feedforward intervention. VSM feedforward (independent variable, IV),…

Being schooled with other high-achieving peers has a detrimental influence on students' self-perceptions: School-average and class-average achievement have a negative effect on academic self-concept and career aspirations--the big-fish-little-pond effect. Individual achievement, on the other hand, predicts academic self-concept and career…

From a disciplinary discourse perspective, all university courses can be said to involve content and language integrated learning (CLIL) even in monolingual settings. Clearly, however, things become much more complex when two or more languages are involved in teaching and learning. The aim of this paper is to introduce readers to the linguistic…

This study examines the effect of a reading intervention aimed at improving the comprehension performance of three students with hyperactive behaviours in Hong Kong. Comprehension tasks, adopted from local exercise books based on Hong Kong Certificate Education Examination Paper I, were used to appraise three participants' reading performance, and…

Differential outcome and differential response to research-based interventions are challenging issues for researchers, teachers, and families of young children with autism spectrum disorder (ASD). In this article, the authors present information on responders to an early education program, Project DATA (Developmentally Appropriate Treatment for…

Previous literature suggests that Parkinson's disease is marked by deficits in timed behaviour. However, the majority of studies of central timing mechanisms in patients with Parkinson's disease have used timing tasks with a motor component. Since the motor abnormalities are a defining feature of the condition, the status of timing in Parkinson's…

This paper studies correction for chance in coefficients that are linear functions of the observed proportion of agreement. The paper unifies and extends various results on correction for chance in the literature. A specific class of coefficients is used to illustrate the results derived in this paper. Coefficients in this class, e.g. the simple…

Given a sequence g[subscript k] greater than 0, the "g-factorial" product [big product][superscript k] [subscript i=1] g[subscript i] is extended from integer k to real x by generalizing properties of the gamma function [Gamma](x). The Euler-Mascheroni constant [gamma] and the beta and zeta functions are also generalized. Specific examples include…

Mantel-Haenszel methods comprise a highly flexible methodology for assessing the degree of association between two categorical variables, whether they are nominal or ordinal, while controlling for other variables. The versatility of Mantel-Haenszel analytical approaches has made them very popular in the assessment of the differential functioning…

There is a great deal of talk about a crisis in teaching across the English-speaking world, about the quality of teachers leaving much to be desired, and about the quality of student outcomes dropping. This, in turn, has resulted in various aspects of teacher preparation coming under severe scrutiny. In general, disquiet has been voiced about the…

The Check in/Check out (CICO) strategy is a secondary tier intervention designed to address those students who are not responsive to universal tier, school-wide positive behavioral interventions and supports (SW-PBIS), and require more targeted support. The present study extended the implementation of the CICO strategy to a residential facility.…

Adolescents with autism struggle with developing meaningful social relationships. Learning appropriate conversational skills can be an important first step in creating friendships. A procedure that has been effective in teaching conversational skills to typically developing adolescents is the teaching interaction procedure, which involves…

People were trained to decode noise-vocoded speech by hearing monosyllabic stimuli in distorted and unaltered forms. When later presented with different stimuli, listeners were able to successfully generalize their experience. However, generalization was modulated by the degree to which testing stimuli resembled training stimuli: Testing stimuli's…

The Iowa Sleep Disturbances Inventory (ISDI) is a new measure of self-reported sleep difficulties, which was designed to help facilitate research on the overlap of sleep disturbances and psychopathology. This instrument was developed in two large student samples using principal factor analyses; the psychometric properties of the scales were then…
