This study examined whether 4- to 8-year-olds considered knowledge prerequisites for pretending and drawing. Children were asked if an artist (actor) who did not know what something was, yet whose drawing (behavior) resembled it, was actually drawing it (pretending to be it). Children performed similarly on pretending and drawing questions.…

Examines the cognitive supports that underlie achievement in science using a cultural historical framework and the activity setting (AS) construct with five features: personnel, motivation, scripts, task demands, and beliefs. Reports four emergent phenomena--science activities, the building of learning, meaning in lessons, and the conflict over…

Two experiments examined six-month-olds' ability to form an abstract containment category. Results indicated that, after habituation to object pairs in a containment relation, infants looked reliably longer at an example of an unfamiliar versus familiar containment relation, indicating that they could form a categorical representation of…

Examines the perceptual cues used by three- and four-month-old infants to categorically distinguish perceptually similar animal species. Indicates that cues form the facial and head region provide the critical source of information that allows young infants to categorically differentiate cats and dogs and presumably a number of other animal…

Assesses the effect of delay between an event and new postevent information related to it in six-month-old infants' memory. Three phenomena were studied: memory impairment, memory facilitation, and categorization. Suggests that postevent information has different qualitative effects depending on its timing, and provides a basis for understanding…

Discusses how daily routines in early childhood and primary grade settings can assist young children's developing understanding of time. Notes adaptable activities, including tracking weather, keeping records, talking about activities, creating time lines, celebrating personal milestones, and recording events and changes. Lists ways to integrate…

Three studies explored children's distinctions between mental and bodily reactions to contamination. Found that children distinguished reactions mediated by representations from those mediated by physical interactions. Data suggested that preschoolers distinguished between physical and mental reactions to contamination but had a poor understanding…

Examines young children's responses to and understanding of death. Discusses children's concepts of death; how their grief process differs from that of adults; stages of grief; factors affecting grief responses; acceptance of children's grief response; support for grieving children, especially funeral services and counseling; and preparing and…

Suggests that Greenberg's challenge to the centrality of object permanence in developmental thinking reveals that developmentalists' theories about childhood speak about their own self-images. Notes that developmentalists have been guilty of not only the object permanence fallacy but also the genetic fallacy, or the mistaken belief that describing…

Two experiments compared preschoolers' awareness of knowledge transitions involving behavioral changes to those involving vocabulary or general knowledge changes. Found that children tended to report they had learned something new when novel information was behavioral (e.g., counting in Japanese) and tended to claim prior knowledge when the novel…

Three studies of how workers construct knowledge associated with vocational practice were examined within a framework classifying dispositions as interest, attitudes, and values. Findings suggest that dispositions are rooted in individual history and participation in communities of practice and that consideration of how cognitive structures…

Notes two faulty aspects of the Reznick et al., twin study (PS 526 688): the expressive language measure at 14 months, which has practically no spread of item difficulty, as well as measures included to assess specific cognitive characteristics; and the notion of infant transition as it affects interpretation of the results.

Two studies investigated development of infants' visual preferences for the human body shape. Results indicated that 18-month-olds had a reliable preference for scrambled body shapes over typical body shapes in line drawings, while 12- and 15-month-olds did not respond differentially. In condition using photographs, only 18-month-olds had reliable…

Three experiments investigated effects of complexity on 2- to 6-year-olds' understanding of a beam balance. Found that 2- to 4-year-olds succeeded on problems that entailed binary relations, but 5- and 6-year-olds also succeeded on problems that entailed ternary relations. Ternary relations tasks from other domains (transitivity and class…

Presents implications for consideration by community, parents, educators, and policymakers if guided by the recommendations of the final report on the "Early Years Study" by McCain and Mustard. Cautions against an overemphasis on brain development during the early years and against viewing children as capital for social policy purposes.…
