Maintains that the primary contribution of Wolfberg's book is its integration of various research literatures and its rich case studies, though its noncritical stance toward prevailing diagnostic paradigms for autism might be a shortcoming. Suggests that the book's reference to developmental stages is remarkably traditional for a text that…

British student teachers (n=240) completed the Teacher Concerns Questionnaire three times during the postgraduate certificate in education course. Concerns decreased between the first and second and first and third administration, but increased between the second and third, suggesting that development of concerns is not sequential. Concerns about…

A study involving 36 children and 10 adults investigated development of auditory frequency and temporal resolution using simultaneous and backward masking of a tone. On the measure of frequency resolution, 6- year-olds performed as well as adults. However, for the backward masking task, 6-year-olds had higher threshold than adults. (Contains…

Visual object processing in infancy is often described as proceeding from an early stage in which object features are processed independently to a later stage in which relations between features are taken into account (e.g., Cohen, 1998). Here we present the Representational Acuity Hypothesis, which argues that this behavioral shift can be…

When do infants begin to communicate positive affect about physical objects to their social partners? We examined developmental changes in the timing of smiles during episodes of initiating joint attention that involved an infant gazing between an object and a social partner. Twenty-six typically developing infants were observed at 8, 10, and 12…

This study examined the dynamics of cognitive abilities and academic achievement from childhood to early adulthood. Predictions about time-dependent "coupling" relations between cognition and achievement based on R. B. Cattell's (1971, 1987) investment hypothesis were evaluated using linear dynamic models applied to longitudinal data (N=672).…

Several studies have demonstrated a relation between executive functioning (EF) and theory of mind (ToM) in preschoolers, yet the developmental course of this relation remains unknown. Longitudinal stability and EF-ToM relations were examined in 81 children at 24 and 39 months. At Time 1, EF was unrelated to behavioral measures of ToM but was…

When an object moves behind an occluder and re-emerges, 4-month-old infants perceive trajectory continuity only when the occluder is narrow, raising the question of whether time or distance out of sight is the important constraining variable. One hundred and forty 4-month-olds were tested in five experiments aimed to disambiguate time and distance…

In about twenty years, starting in 1984, Bangalore has become the fourth best "Global Hub of Technological Innovation", according to Business Week. This article reviews the major milestones in Bangalore's development and the interactive roles of government, universities and private entrepreneurs. The author offers a new model: innovation…

In this article, the authors discuss how children learn to problem solve from birth to 6 years. At 0 to 2 years, children learn to be very effective problem solvers by encouraging children's explorations and supporting their efforts to resolve difficulties. When they reach 3 years old, children enjoy experimenting with a wide variety of materials,…

By watching, listening, and offering gentle reassurance, you can help young children work through their fears. Sudden noises, movement, or unfamiliar people often frighten babies. After 12 months of nurturing experiences with familiar teachers and routines, a baby is more prepared and less easily startled. Preschoolers have a variety of fears such…

This article examines the process of graphic representational development in paint in the context of the theoretical assumptions of traditional developmental stage theory. Consistent with current theory and research in art education and cognitive psychology, a model of painting development is proposed that is multidimensional rather than unitary,…

We present the results of multivariate normal mixture modeling of Piagetian data. The sample consists of 101 children, who carried out a (pseudo-)conservation computer task on four occasions. We fitted both cross-sectional mixture models, and longitudinal models based on a Markovian transition model. Piagetian theory of cognitive development…

The authors asked whether there is evidence to support the existence of the vocabulary spurt, an increase in the rate of word learning that is thought to occur during the 2nd year of life. Using longitudinal data from 38 children, they modeled the rate of word learning with two functions, one with an inflection point (logistic), which would…

The development of reading depends on phonological awareness across all languages so far studied. Languages vary in the consistency with which phonology is represented in orthography. This results in developmental differences in the grain size of lexical representations and accompanying differences in developmental reading strategies and the…
