Reports four studies investigating very young children's understanding of two kinds of symbolic stimuli--scale models and pictures. The data indicate that 2.5-year-old children have difficulty understanding scale models as symbols but can understand pictures as symbols. Results suggest that experience with a symbolic medium they understand can…

Maintained that preschoolers' class inclusion task judgments and justification may be modeled as mixtures of different probability distributions, with different response strategies equivalent to different distributions. Found that justifications lagged behind judgments in development. Concluded that, if a single response variable is to be…

Discusses the need to ground critique by incorporating reflexive dialogical practice in management learning as a way of developing more critical and responsive practitioners. Reconstructs learning as reflective/reflexive dialogue in which participants connect tacit knowing and explicit knowledge. (Contains 75 references.) (Author/YDS)

In their commentaries, Carver, Richmond and DeBoer pose several challenging and insightful questions in response to our target article. Two key themes emerged from their commentaries, which are important in the field of infant memory research. The first concerns the use of deferred imitation as a paradigm, and its relationship to other methods of…

This study investigated 3- and 4-year-old's understanding of the relationship between pretense and mental awareness. In Experiments 1 and 2, only a subset of 4-year-olds recognized that sleeping characters and characters ignorant of their appearance were not pretending. However, these experiments had certain linguistic demands, which potentially…

The author argues that the gap between theory of mind and moral reasoning research may be more apparent than real. The wider gap is between sociomoral cognitions and real-world behavior. She calls for research on the relation of children's mental state and moral understanding to their sociomoral behavior.

Research to date has demonstrated that networking can be an effective strategy for supporting meaningful learning. However, studies have shown that learners encounter difficulties using it. In an attempt to understand and thus reduce these difficulties, this study examined learners' underlying cognitive processes and activities while networking.…

Substantial evidence suggests that young children reason about illnesses using biological causal principles and that, with increasing age, children provide more explicit accounts of mechanisms underlying different conditions. To investigate these claims, sixteen 7-8 year-old children and sixteen 11-12 year-old children with attention…

Two experiments are described that investigate the ability to infer the number of items in one-to-one corresponding sets for two age groups. We assess the influence of set size, the visibility of sets, and the way in which set equivalence is derived - pairing versus sharing - using a repeated-measures design. Three-year-olds are largely restricted…

Based on close observations of two 4-year-old children responding to their parents' requests for quantitative comparisons, we offer a "participationist" account of the origins and development of numerical thinking, one that portrays numbers as a product rather than a pregiven object of human communication. In parallel, we propose a…

The domain-independent and domain-dependent approach to the evolution of cognition have been taken by separate groups of researchers who have focused exclusively on either the formal properties or the distinct cognitive demands of tasks. We express the view that synthesizing the two approaches could lead to a more complete understanding, and…

Rigorously evaluated prenatal and infancy home visitation programs for families at risk have proven to effectively prevent the development of early onset and later conduct problems. the German pilot project "Pro Kind" is an adaptation of the US evidence-based Nurse-Family Partnership program. It has been evaluated in a longitudinal…

Attention has been focused for decades on the need to improve high school students' preparation for the workplace. Employers report that nearly half of their entry-level employees are inadequately prepared and lack basic communication and critical thinking skills as well as a work ethic. Although a postsecondary credential is considered necessary…

This work examines the relationship between implicit procedural and implicit verbal processes as they occur in natural adult conversation. Theoretical insights and empirical findings are rooted in a move towards integration of Bucci's "Referential Activity" (RA) and "Multiple Code" perspectives and Beebe and Jaffe's…

Poverty remains an urgent crisis worldwide. In the United States, 28.6 million children live in low-income families and 12.7 million children live in poor families. In nations belonging to the Organization for Economic Co-operation and Development (OECD), 47 million children live below national poverty lines. These figures pertain to…
