Aim: To compare function and gait in a group of children older than most children who received selective dorsal rhizotomy (SDR) with age- and function-matched peers who received either orthopedic surgery or no surgical intervention. Method: A retrospective study examined ambulatory children with diplegic cerebral palsy, aged between 10 years and…

This study elaborates the Rasch differential item functioning (DIF) model formulation under the marginal maximum likelihood estimation context. Also, the Rasch DIF model performance was examined and compared with the Mantel-Haenszel (MH) procedure in small sample and short test length conditions through simulations. The theoretically known…

Objective: There is clinical heterogeneity among the autism spectrum disorders (ASD). The presence of dysmorphology (minor physical anomalies; MPAs) is one possible tool for defining a clinically relevant subset in ASD. This study employs an adaptation of Miles and Hillman's (2000) classifications by using photographs to identify a subgroup with…

The importance of "size and scale" in nanoscience and engineering has been recognized by both scientists and science educators. A solid understanding of this concept is key to the learning of nanoscience. Students, however, have been reported to have considerable difficulty grasping this concept; yet little is known regarding their state…

This article offers a comment on the ways multilingual language users perceive their L2 and L3 learning experiences at the level of appraisals, that is, variables that "assign value to current stimuli based on past experience". In the theoretical part of the article the concept of appraisals is introduced and briefly outlined from the different…

Researchers have recognized the importance of developing an accurate classification system for externalizing disorders, though much of this work has been framed by a priori preferences for categorical vs. dimensional constructs. Newer statistical technologies now allow categorical and dimensional models of psychopathology to be compared…

Although behavioral difficulties are well documented in reading disabilities, little is known about the relationship between math ability and internalizing and externalizing behaviors. Here, we use standardized measures to investigate the relation among early math ability, math anxiety, and internalizing and externalizing behaviors in a group of…

Autism spectrum disorder and attention deficit hyperactivity disorder are neurodevelopmental disorders that cannot be codiagnosed under existing diagnostic guidelines ("Diagnostic and Statistical Manual of the American Psychiatric Association," 4th ed., text rev.). However, reports are emerging that attention deficit hyperactivity…

In 2003, UNICEF-Kenya and the Kenyan Ministry of Education introduced the "Child Friendly Schools" initiative to encourage educational policy makers and practitioners to look for alternative ways to measure the quality of primary schools beyond pupils' test scores. In 2009, Kenyan government officials distributed the Child Friendly…

The aim of the current study was to examine the effects of bilingualism on letter and category fluency tasks. Participants were 1,600 monolingual and bilingual children from three cities in Iran: Tehran (Persian monolinguals), Tabriz (Turkish-Persian bilinguals), and Sanandaj (Kurdish-Persian bilinguals). We separately presented nine Persian…

A six-year-old child was independently assessed by three licensed educational (school) psychologists and one interdisciplinary team in the UK. All but one of these practitioners believed their assessment to be the first. The aim was to compare the practice of assessors and their conclusions especially in diagnostic categorisation. The methods of…

The purpose of this quantitative study was to compare the emotional intelligence competencies of a group of technical experts with high skills in problem-solving, leadership and mentoring (Group A) with a group of technical experts with lower skills in problem solving, leadership, and mentoring (Group B) at a semiconductor manufacturing factory in…

To compare the functioning profiles of patients receiving different types of organ transplants using the International Classification of Functioning, Disability, and Health. The patients (n=102) were enrolled between days 5 and 10 after discharge following receipt of an organ transplant, and assessed for sociodemographic variables, the Functional…

The taxometric method effectively distinguishes between dimensional (1-class) and taxonic (2-class) latent structure, but there is virtually no information on how it responds to polytomous (3-class) latent structure. A Monte Carlo analysis showed that the mean comparison curve fit index (CCFI; Ruscio, Haslam, & Ruscio, 2006) obtained with 3…

This study was designed to examine whether embodied agent integrated with the pedagogical approach of learning by asking questions impacts lower academic ability students' perceived science self-efficacy beliefs, immediate and delayed retention and whether the students' cognitive styles interact with the treatment condition in the outcome…
