Developmental scientists are often interested in subgroups of people who share commonalities in aspects of development; these subgroups often cannot be captured directly but instead must be inferred from other information. Mixture models can be used in these situations. Two specific types of mixture models, latent profile transition analyses and…

This book provides a fresh approach to motivation in primary school children by exploring the role of metaphor and symbol in language and art as a means of expressing insights developed through learning. The book investigates and transcends Piaget's dominant child developmental theories and considers alternative theories from psychiatry, not least…

Maria Montessori developed a form of education in the first half of the last century that came to be called by her surname, and research indicates it often has positive outcomes. In the years since its development, tens of thousands of schools worldwide have called their programs "Montessori," yet implementations vary widely, leading to…

This paper outlines a qualitative research tool designed to explore personal identity formation as described by Erik Erikson and offers self-reflective and anonymous evaluative comments made by college students after completing this task. Subjects compiled a list of 200 myths, customs, fables, rituals, and beliefs from their family of origin and…

The article discusses problems inherent in using the developmental model in the implementation of programs for young children with disabilities, and proposes a reconceptualization based upon M. Lewis and M. Starr's salient responses model. The primary components of this model are presented, along with their implications for early intervention…

Concepts important to cognitive development in children can be classified according to several levels. At level 1, concepts are equivalent in structural complexity to binary relations and univariate functions. At level 2, concepts are equivalent to compositions of binary relations, binary operations, and bivariate functions. At level 3, concepts…

Assesses three sets of Piagetian exclusion operations (of varying the independent variables, of holding the independent variable constant, and tautology) and of levels of thought (concrete through formal) in 33 fifth graders, 27 sixth graders, and 31 seventh graders. (HOD)

Deconstructs the prevailing paradigm of childhood development. Argues that childhood is a social construction and traces changing images of childhood throughout history. Criticizes well-intentioned but devitalizing day care and kindergarten practices. Argues for a child-centered perception of childhood. (FMW)

This study of 102 individuals with autism found that the brainstem and cerebellum increased in size with age but were significantly smaller in autistic patients than in controls. Analysis of the speed of development suggests that brainstem and vermian abnormalities in autism were due to an early insult and hypoplasia rather than to progressive…

Acoustic analyses, along with perceptual ratings, measured the extent to which preschoolers imitated three modeled intonation contours (declarative, interrogative, and monotone). Results indicated that five-year-old children imitated modeled contours more frequently than did three-year-old children, with between-group differences largely because…

To test opposing theories about the relationship between intonation and syllable timing, these boundary features were compared in a longitudinal study of 9 children's speech development between the mean ages of 16 and 25 months. Results suggest that young children acquire the skills that control intonation earlier than they do skills of final…

This study that examined the economic reasoning of preschool and elementary school children concluded that (1) the nature of children's economic reasoning is supportive of cognitive development theory; (2) children's economic reasoning varies somewhat by personal experiences, and (3) the intermediate grades are an appropriate level to emphasize…

This article uses a case study of a deaf-blind infant to examine issues in the early cognitive development of such infants. The study used an ecological approach involving naturalistic observation, videotaping, anecdotal accounts, and the use of four global developmental scales. (DB)

Most research into interactions between mothers and their infants with hearing impairments focuses on mothers' and infants' behaviors separately, speculating about the interplay among these behaviors and their effects on child development. In the present article, an intersubjective developmental theory focusing on the development of the…

Many studies have hypothesized a developmental relationship between children's chronological and mental ages and their intrapersonal perceptions of internal and external control. To investigate longitudinal changes in children's locus of control, 97 elementary school children, between the ages of 8 and 13, were administered the Children's…
