Developmentalists have overlooked the problem of the real impermanence of things. Though the metaphor of impermanence is central to Piagetian and neo-nativist accounts of representation, the development of the understanding of impermanence is unstudied. This article proposes that the development of the concept of impermanence is distinct from the…

Examined whether active participation in the setup of a trick significantly affected the performance of young (mean 40 months) and old (mean 45 months) 3-year olds on questions concerning individuals' ignorance of and false beliefs about a situation. Results suggest that even young 3-year olds have the ability to understand false mental states.…

The theory-of-mind abilities of twins, children with nontwin siblings, and only children were compared to investigate further the link between number and type of siblings and theory-of-mind abilities. Three- to 5-year-old children with nontwin siblings outperformed both only children and twins with no other siblings, twins who also had other…

This review begins with a brief history from Piagetian perspective-taking development, through metacognitive development, and into the past and present field of theory-of-mind development. This field has included research on what infants and children know about a variety of mental states, on possible causes and consequences of mentalistic…

Head Start is a federally funded preschool program for poor children designed to help close the gap between those children and their more advantaged peers before they begin public schooling. Given that Head Start appears to have positive long-run impacts on its recipients, a natural and important next question to ask is: What are the channels…

The foundations of brain architecture are established early in life through a continuous series of dynamic interactions in which environmental conditions and personal experiences have a significant impact on how genetic predispositions are expressed. Because specific experiences affect specific brain circuits during specific developmental…

This study tests the firm distinction children are said to make between living and nonliving kinds. Three, 4-, and 5-year-old children and adults reasoned about whether items that varied on 3 dimensions (alive, face, behavior) had a range of properties (biological, psychological, perceptual, artifact, novel, proper names). Findings demonstrate…

We conducted four experiments to examine developmental differences in preferences for using color, size, and location information to disambiguate hiding places. Three- and 4-year-olds and adults described how to find a miniature mouse that was hidden in one of two highly similar small objects in a dollhouse. In Experiment 1, the hiding places…

Fuzzy trace theory explains why children do not have to use rules of logic or premise information to infer transitive relationships. Instead, memory of the premises and performance on transitivity tasks is explained by a verbatim ability and a gist ability. Until recently, the processes involved in transitive reasoning and memory of the premises…

This paper analyses how countries in UNICEF's East Asia and Pacific Region (EAPR) have engaged in the Early Learning and Development Standards (ELDS) process. ELDS has been developed by the governments of Cambodia, China, Fiji, Lao PDR, Mongolia, Philippines, Thailand, and Vietnam over the last 3 years with technical and financial support from…

In his work as a family therapist and researcher with children and families in educational and community settings, the author encounters children who are anxious, depressed, lacking in empathy, self-esteem and motivation, and naive in their expectations about their physical and mental abilities. They haven't been properly challenged. These kids…

The developing brain has the capacity for a great deal of plasticity. A number of investigators have demonstrated that intellectual and language skills may be in the normal range in children following unilateral perinatal stroke. Questions have been raised, however, about whether these skills can be maintained at the same level as the brain…

This study examines the earliest jokes produced by three children and investigates how these jokes contribute to a model of humor development. Subjects were three male infants, and data was collected through a diary record procedure kept by the children's parents. Data was collected on one child at age 13 months; data collection for the other two…

This article presents an argument, based on psychological research and inferences about human evolution, for the plausibility of an intrinsic altruistic motive. A theoretical model for the development of such a motive is outlined. (JMB)
