This study attempts to rebut criticisms of the developmental theories of Jean Piaget by showing that most criticisms derive from misinterpretation and forget the dialectical, constructivist, and developmental nature of Piaget's work. Important aspects of Piaget's theory have not been assimilated by developmental psychologists. (SLD)

This "classic" article (1972) in the field of deaf studies includes some interpretive notes for current readers. The article examines the effect of deafness on basic developmental tasks at each of the eight developmental stages of Erik Erikson's theory of psychosocial development and explains the more successful passage through these…

Discusses the four planes of development and the periods of creation and crystallization within each plane. Identifies the type of independence that should be achieved by the end of the first two planes of development. Maintains that it is through individual work on the environment that one achieves independence. (KB)

A study of 28 infants (ages 8-12 months) investigated their ability to drink from a straw. Results indicate 22 percent were not able to drink from a straw, whereas 78 percent were able to do so. Data failed to reveal any significant differences based on gender, age, or ethnicity. (Contains nine references.) (Author/CR)

Notes that scientists understand in greater detail the various anatomical and neurological changes that allow children to develop motor and sensory abilities. Explores how the research findings are calling into question the notion of prescribed developmental milestones. (HTH)

In this study, seven children with specific language impairment (SLI) and speech deficits were matched with same age peers and evaluated for iambic (weak-strong) and trochaic (strong-weak) prosodic speech forms. Findings indicated that children with SLI and speech deficits show less mature segmental and speech motor systems, as well as decreased…

Investigates differential effects of goal specificity on maze learning among 40 young and 40 old adults. Results confirmed hypotheses that the presence or absence of a specific goal would disproportionately compromise or enhance, respectively, elderly people's performance. Suggests that instruction based on cognitive load theory can compensate for…

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…
