Spatial scaling is an integral aspect of many spatial tasks that involve symbol-to-referent correspondences (e.g., map reading, drawing). In this study, we asked 3-6-year-olds and adults to locate objects in a two-dimensional spatial layout using information from a second spatial representation (map). We examined how scaling factor and reference…

Considerable evidence indicates that shape similarity plays a major role in object recognition, identification and categorization. However, little is known about shape processing and its development. Across four experiments, we addressed two related questions. First, what makes objects similar in shape? Second, how does the processing of shape…

We analyze theoretical differences between conceptualist and minimalist approaches to episodic processing in young children. The "episodic-like" minimalism of Clayton and Dickinson (1998) is a species of the latter. We asked whether an "episodic-like" task (structurally similar to ones used by Clayton and Dickinson) in which participants had to…

Two tasks were administered to 40 children aged from 16 to 20 months (mean age = 18;1), to evaluate children's understanding of declarative and informative intention [Behne, T., Carpenter, M., & Tomasello, M. (2005). One-year-olds comprehend the communicative intentions behind gestures in a hiding game. "Developmental Science", 8, 492-499;…

The present study investigated the role of the causal status of features and feature type in biological categorizations by young children. Study 1 showed that 5-year-olds are more strongly influenced by causal features than effect features; 4-year-olds exhibit no such tendency. There therefore appears to be a conceptual change between the ages of…

Young children's integration of weight and distance information was examined using a new methodology that combines a single-armed apparatus with functional measurement. Weight and distance values were varied factorially across the item set. Children estimated how far the beam would tilt when different numbers of weights were placed at different…

Adolescents (N = 46; M = 12.46 years) who had previously participated in a longitudinal study of autobiographical memory development narrated their early childhood memories, interpreted life events, and completed a family history questionnaire and language assessment. Three distinct components of adolescent memory emerged: (1) age of earliest…

Barrett, Richert, and Driesenga [Barrett, J. L., Richert, R. A., & Driesenga, A. (2001). "God's beliefs versus mother's: The development of nonhuman agents concepts." "Child Development," 72(1), 50-65] have suggested that children are able to conceptualize the representational properties held by certain super-natural entities, such as God, before…

In theory of mind research, there is a long standing dispute about whether children come to understand the subjectivity of both desires and beliefs at the same time (around age 4), or whether there is an asymmetry such that desires are understood earlier. To address this issue, 3-year olds' understanding of situations in which two persons have…

This paper advances the hypothesis that young children use narrative play and stories to construct two types of fiction, the worlds of "what is" and "what if." Heinz Werner's conceptualization of children's spheres of reality, in which actions, symbols, and events are constructed in particular ways, is used as a theoretical framework for…

Age-related changes in mental flexibility, in the form of task switching, were assessed in 292 children (58-156 months old). Task switching was examined with a new task for young children, the Switch Task for Children (STC). The STC consists of two easy, comparable games and does not require reading skills, which makes it suitable for children…

Compared the use of conditional logic in adult-adult and adult-child conversation. Results indicated that conversation patterns and inferences were similar except that children made fewer independent inferences and shifts in taxonomic level and responded more frequently to socially controlling statements than did adults.
