Puts reading and spelling difficulties in a cognitive developmental perspective that views the acquisition of reading, writing, and spelling as a sequence of characteristic strategies for dealing with written language. Concludes that the ultimate goal is to reduce the great number of children who fail to acquire literacy due to teachers' lack of…

Explored in three experiments children's understanding of emotion in speech. Found gradual developmental change from 4-year-olds' focus on content to adult's focus on paralanguage. Children exhibited greater response latencies to utterances with conflicting cues than to those with nonconflicting cues. They accurately labeled affective paralanguage…

Preschoolers viewed stimulus sets comprised of a sample picture and three types of matches and were asked to choose a match that "went with" each sample. Children's choices indicated that a shift occurs between 3 and 4 years of age from a taxonomic bias to a thematic bias. Animate sample stimuli enhanced children's tendency to adopt…

Procedural understanding should be taught to students for an understanding of the 'nature of science'. Considers some of the concepts of evidence that are particularly important to biology, and discusses how and why these ideas could be taught. (Contains 21 references.) (Author/YDS)

Trained 3-, 5-, and 8-year-olds in temporal bisection task, with nonstandard comparison stimuli spaced linearly between short or long standard visual stimuli. Statistical analyses and results from different theoretical models of the data all suggested that temporal sensitivity was higher in the 8-year-olds than in younger groups, even when the…

Two experiments examined relation between age-related changes in retention and age-related changes in the misinformation effect. Found large age-related retention differences when participants were interviewed immediately and after 1 day, but after 6 weeks, differences were minimal. Exposure to misleading information increased commission errors.…

Analysis of course videos of 11 instructors of agricultural distance education courses showed their instruction achieved objectives for lower-level cognition (remembering, processing) but not higher-level outcomes (creating, evaluating). The cognition level of Iowa Communications Network courses was higher than those delivered by other distance…

Assessed the relationship between temporally distant antecedent events (TDEs) and the frequency and function of aggressive and out-of-seat behaviors occurring in school. Results were consistent with previous literature that describes certain antecedent events as establishing operations. Discussion includes how these events interact to alter the…

Infants' abilities to identify objects based on their perceptual features develop gradually during the first year and possibly beyond. Earlier we reported [Kaldy, Z., & Leslie, A. M. (2003). Identification of objects in 9-month-old infants: Integrating "what" and "where" information. Developmental Science, 6, 360-373] that infants at 9 months of…

Young children in poor communities are spending more hours in nonparental care because of policy reforms and expansion of early childhood programs. Studies show positive effects of high-quality center-based care on children's cognitive growth. Yet, little is known about the effects of center care typically available in poor communities or the…

A large literature has documented the influence of child care on young children's development, but few studies have examined low-income children in community care arrangements. Using data from Welfare, Children, and Families: A Three-City Study (N=204), this study examined the influence of child care quality and the extent of care on low-income…

Children's drawings are thought to be a mirror of a child's representational development. Research suggests that with age children develop more complex and symbolic representational strategies and reference points become more differentiated by gender. We collected two drawings from 109 5-13-year-old children (three age groups). Each child drew…

Children from seven classes representing the year groups in a primary school were interviewed in groups of three or four to find out their understanding and views on issues related to the environment and science. The large majority showed considerable interest and concern about environmental issues related to their experience and understanding,…

Niels Bohr's term "complementarity" has been used by several authors to capture the essential aspects of the cognitive and epistemological development of scientific and mathematical concepts. In this paper we will conceive of complementarity in terms of the dual notions of extension and intension of mathematical terms. A complementarist approach…

This study examined the effect of exemplar typicality on reaction time and accuracy of categorization. High-functioning children (age 9-12), adolescents (age 13-16), and adults with autism (age 17-48) and matched controls were tested in a category verification procedure. All groups showed improved processing throughout the lifespan for typical and…
