We focus on integrating developmentally appropriate practices, the project approach of Reggio Emilia, and a behavior analytic model to support a quality preschool environment. While the above practices often are considered incompatible, we have found substantial overlap and room for integration of these perspectives in practical application. With…

Patterns of development of ToM belief abilities in intellectually disabled (ID) children and typically developing (TD) children matched on their developmental age were investigated. The links between cognition, language, social understanding and ToM belief abilities were examined. EDEI-R [Perron-Borelli M. (1996). "Echelles Differentielles…

Recent interest in gesture has led to an understanding of the development of gesture and speech in typically developing young children. Research suggests that initially gesture and speech form two independent systems which combine together temporally and semantically before children enter the two-word period of language development. However,…

Despite many disagreements on the utility of neuropsychological applications in schools, executive function measures have been found to be useful across a variety of areas and ages. In addition, many disagreements are extant in discussions of the maturational course of the development of executive functioning abilities that are dependent on…

Preschool teachers use the domino effect--standing dominos on end in rows and pushing one over--to examine how play contributes to children's acquisition of knowledge. Using diagrams, photos, and vignettes of children between the ages of 3 and 5 years, the authors demonstrate how children at different stages of development use physical knowledge…

Explores development of cognitive representation in 20 infants 12 to 24 months of age with regard to (l) their understanding of agency in symbolic play (agent use), (2) recognition of their own mirror image, and (3) object permanence. Results were generally consistent with developmental sequences predicted by Fischer's Skill Theory for agent use…

Analysis of spontaneous language samples of six children (two to four years old) at three linguistic ages (defined by mean length of utterance in morphemes) replicated the proposed semantic ordering of question types. However, a stage characterized by uninverted forms was not supported. (CL)

The influence of referent type (Objects vs. Actions) and within-category referent relationships (functionally similar vs. perceptually similar) upon acquisition of lexical concepts by 12 infants were examined. Ss acquired object words and concepts in greater numbers than action words and concepts, suggestive of differences in the underlying…

Developmental stages in causal reasoning and causative expression are outlined to provide comparison with preschool handicapped children. Three stages within the preschool range are defined in terms of changes in causal schemes, field of centration, and experimental attitude and skills. Suggestions for assessment and special education are made.…

Three experiments tested whether 12- to 24-month-old children showed systematic search, persistence, and/or end-screen search in the invisible-displacement task. A fourth study tested whether end-screen search resulted from seeing the experimenter move his hand through the series of screens. (RH)

Investigates the development of preferences for different types of metaphors among subjects at seven ages (from 6 through 20 years). Subjects received incomplete sentences followed by metaphorical and literal completions and were asked to select their preferred completions. Pattern of preferences shifted with age. (Author/RH)

Introduces a notation system for representing the formal aspects of Erikson's theory of psychological development in adolescence (including consideration of stages and transitions from one stage to the next) and uses this notation system to raise and make some researchable questions regarding Erikson's conceptions of the crises of identity and…

Premeaningful vocalizations produced by nine normally developing and 10 Down's syndrome infants were recorded as part of a longitudinal study of language development. Both groups began to produce canonical, reduplicated babbling at 8 to 8 1/2 months of age, and trends regarding consonantal and vocalic development for both groups were similar…

Differences in moral development (as conceived by Kohlberg) were examined in a sample of delinquent teenagers. The repeater group was not found, as had been hypothesized, to be lower on moral maturity than those who engaged in less delinquency. (GC)
