The current paper reviews four research perspectives that have been used to investigate the development of risk-taking. Cognitive developmental research has investigated the development of decision-making capacities that potentially underlie risk-taking development, including sensitivity to risk, probability estimation, and perceptions of…

Because early theoretical frameworks such as Piaget's stage model and social learning theory sought to explain the development and performance of imitation in terms of overall group trends, any evidence for individual differences in this behavior was until recently largely overlooked. Results of contemporary imitation studies have not only begun…

This paper reviews evidence on the family origins of racial differences in young children's test scores and considers how much of the gap is due to differences in the economic and demographic conditions in which black and white children grow up. Our review of the literature finds that the estimated size of the gaps varies considerably across…

Individual differences in development or growth are typically handled under conventional analytical approaches by blocking on the variables thought to contribute to variation, such as sex or age. But such approaches fail when the differences are attributable to latent characteristics (i.e., variables not directly observable beforehand) within the…

In this paper we examine two long-standing assumptions of the information processing perspective of perceptual-motor development, namely that: (1) the amount of noise in children's sensori-motor system decreases with increases in age up to adulthood; and (2) this age-related reduction in noise level leads to associated improvements in the accuracy…

This paper reviews the relations found in the literature among poverty, maternal depression, early intervention, and child developmental outcome and a theoretical model is suggested. Mother-child transactional processes have been found to be impaired under conditions of poverty and maternal depression, leading to non-optimal outcomes in children.…

We review and provide empirical evidence to show that infants categorize and process male and female faces differently, with an advantage in processing female faces. To understand this asymmetry in categorization and processing of male and female faces, we evaluate three mechanisms influencing infant categorization of male and female faces:…

A meta-analytic review was conducted of 77 studies including 93 samples and 18,339 participants that examine both the short-term and long-term stability of four continuous dimensions of sociometric status: acceptance, rejection, social preference, and peer ratings. A large mean short-term stability was found for each dimension, indicating good…

Shame plays a central role in social and self development. This review presents an overview of the existing state of the developmental literature on shame, describing the major developmental theories of shame, research on the sources of individual differences in proneness to shame, and implications for mental and physical health. By toddlerhood,…

The purpose of this paper is to synthesize research on picture book reading with young children (i.e., children under the age of 3). In this paper, we review cross-sectional, longitudinal, and intervention reading research and describe changes in both parental and children's behaviors during picture book reading from birth to age 3. Research…

Early acceleration of students in mathematics (in the form of early access to formal abstract algebra) has been a controversial educational issue. The current study examined the rate of growth in mathematics achievement of accelerated gifted, honors, and regular students across the entire secondary years (Grades 7-12), in comparison to their…

We outline the nature of dynamic systems, both linear and nonlinear, and we review dynamic systems principles that apply well to various aspects of human development, including the emergence of new forms, phases of stability and instability, continuous and discontinuous change, and differentiation among individual trajectories. We then document…

Brain development is self-organizing in that the unique structure of each brain evolves in unpredictable ways through recursive modifications of synaptic networks. In this article, I review mechanisms of neural change in real time and over development, and I argue that change at each of these time scales embodies principles of self-organizing…

Traditional approaches to cognitive development concentrate on the stability of cognition and explain that stability via concepts segregated from perceiving acting. A dynamic systems approach in contrast focuses on the self-organization of behavior in tasks. This article uses recent results concerning the embodiment of cognition to argue for a…

In this paper, we consider how concepts from dynamic systems (such as attractors, repellors, and self-organization) can be applied to the study of young children's peer relationships. We also consider how these concepts can be used to explore basic issues involving early peer processes. We use the dynamical systems approach called state space grid…
