Acquisitionists generally assume a relation between code-mixing in young bilingual and trilingual children and language dominance. In our cross-sectional study we investigated the possible relation between code-mixing and language dominance in 122 children raised in Spain or Germany. They were bilingual, trilingual or multilingual, the latter…

The present paper was written under the auspices of the interdisciplinary research group "Educational Processes, Competence Development, and Selection Decisions at Preschool and Primary School Age (BiKS)" (FOR 543), funded by the German Research Foundation (DFG). The surveys were conceptualised and supervised as part of the developmental…

Rigorous research provides information that will allow ECE (Early Childhood Educator) programs to select interventions that have a scientifically based track record of effectiveness in increasing teachers' skills and teaching quality. This paper shares implementation and impact results as well as the lessons learned in conducting an evaluation of…

Translational research inspired by behavioral momentum theory in the area of developmental disabilities has shown effects in individuals over a range of functioning levels. In the current study, behavioral momentum was assessed in 6 children diagnosed with autism and severe intellectual disability. In a repeated measures design, participants were…

Recent advances in methods and computer software for longitudinal data analysis have pushed researchers to more critically examine developmental theories. In turn, researchers have also begun to push longitudinal methods by asking more complex developmental questions. One such question involves the relationships between two developmental…

THIS STUDY USED TWO INTACT CLASSES OF PUBLIC SCHOOL TRAINABLE MENTALLY RETARDED CHILDREN TO STUDY THE EFFECTS OF PHYSICAL ACTIVITIES DERIVED FROM THE DOMAN-DELACATO THEORY OF PHYSICAL AND INTELLECTUAL DEVELOPMENT. THE EXPERIMENTAL GROUP CONSISTED OF SEVEN MALES AND SIX FEMALES FROM AGE 8 TO 18 AND THE CONTROL GROUP CONSISTED OF 10 MALES AND SIX…

The Peabody Picture Vocabulary Test (PPVT) was compared to the Wechsler Intelligence Scale for Children, Revised (WISC-R) in a sample of 30 children with reading disabilities who had been referred to a university clinic. All the children completed the WISC-R; nineteen children completed Form A and eleven children completed Form B of the PPVT. All…

This report is a review of reliability data on the PPVT obtained from 32 research studies published between 1965 and 1974. For average children in the elementary grades, and for retarded people of all ages, PPVT scores remained relatively stable over time and there was close equivalence between alternate forms. (Author)

This paper focuses on the communication and language phenotypes associated with three genetic disorders: Down syndrome, Williams syndrome, and fragile X syndrome. It is argued that there is empirical evidence that these disorders predispose children to specific profiles of strength and weakness in some areas of speech, language, and communication,…

Low income and middle income four- and five-year old children were shown stimuli in three forms: objects, colored pictures, and black and white line drawings taken from commonly used assessment instruments, and were asked to label the stimuli. Results indicated both groups of children labeled the objects more successfully than the pictures.…

Investigated a model of metalinguistic awareness, which consists of two components (the control of linguistic processing and the analysis of linguistic knowledge), in children between the ages of five and seven years. Each of the two components was assessed by four metalinguistic tasks. (Contains 35 references.) (JL)
