We examined the health status of 171 countries by employing factor analysis on various national health indicators for the period 2000-2005 to construct two new measures on health. The first measure is based on the health of individuals and the second on (the quality of) the health services. Our measures differ substantially from indicators used in…

Aim: Children with cerebral palsy (CP) are reported to have learning and social problems. The aim of the present study was to examine whether children with CP have impairments in attention or executive function. Method: We examined attention and executive function with standardized neuropsychological measures in a group of children with unilateral…

This study examines the motion verb system of Bulgarian, focusing both on the structure of the Bulgarian motion verb itself, and on the information typically encoded in the Bulgarian verb of motion. It then compares the Bulgarian motion verb system with the motion verb systems of two other Slavic languages, Russian and Bosnian-Croatian-Serbian…

Today, more minority students are entering undergraduate programs than ever before, but they earn only 6% of all science or engineering PhDs awarded in the United States. Many studies suggest that hands-on research activities enhance students' interest in pursuing a research career. In this paper, we present a model for the implementation of…

Early intervention has been reported to improve outcome in children with autism spectrum disorders (ASDs). Several studies in the field have been randomized controlled trials (RCTs). The aim of this study was to assess ASD outcome in a large naturalistic study. Two hundred and eight children, aged 20-54 months, with a clinical diagnosis of ASD…

The purpose of this study was to analyze and compare diagnoses of patients from a special outpatient department for infants, toddlers and preschoolers. Specifically, overlap, age and gender differences according to the two classification systems DC: 0-3R and ICD-10 were examined. 299 consecutive children aged 0-5;11 years received both ICD-10 and…

The objective was to identify the predictors of length of stay--the impact of age, comorbidity, and stroke subtype--on the outcome of geriatric stroke patients. One hundred and seventy stroke patients (129 first-ever ischemic, 25 hemorrhagic, and 16 ischemic second strokes) were included in the study. The Oxfordshire Community Stroke Project…

A variety of studies have demonstrated that organizing stimuli into categories can affect the way the stimuli are perceived. We explore the influence of categories on perception through one such phenomenon, the perceptual magnet effect, in which discriminability between vowels is reduced near prototypical vowel sounds. We present a Bayesian model…

Category learning can be achieved by identifying common features among category members, distinctive features among non-members, or both. These processes are psychologically and computationally distinct, and may have implications for the acquisition of categories at different hierarchical levels. The present study examines an account of children's…

Over the last few decades, classroom training in aviation education has continued mostly unchanged. It remains a highly structured presentation of information in a lecture format. The purpose of this study was to determine the effect of a method of teaching aeronautical decision making in aviation education based on integrated and scaffolded…

Prior research on students' uses of technology has suggested it can be used to support students' development of formal justifications and proofs. The ways in which these technologies influence the construction of arguments and proofs remain uncertain. Furthermore, research has not been conducted that compares the arguments students develop while…

Objective: The purpose of this study was to empirically derive eating disorder phenotypes in a clinical sample of children and adolescents using latent profile analysis (LPA), and to compare these latent profile (LP) groups to the DSM-IV-TR eating disorder categories. Method: Eating disorder symptom data collected from 401 youth (aged 7 through 19…

Failure to selectively attend to a facial feature, in the part-to-whole paradigm, has been taken as evidence of holistic perception in a large body of face perception literature. In this article, we demonstrate that although failure of selective attention is a necessary property of holistic perception, its presence alone is not sufficient to…

Identifying the set of cognitive processes (CPs) a student can go through during computer programming is an interesting research problem. It can provide a better understanding of the human aspects in computer programming process and can also contribute to the computer programming education in general. The study identified the presence of a set of…

Biostatistics is traditionally a difficult subject for students to learn. While the mathematical aspects are challenging, it can also be demanding for students to learn the exact language to use to correctly interpret statistical results. In particular, correctly interpreting the parameters from linear regression is both a vital tool and a…
