This paper presents how the medico-hygienist model of childhood, which had prevailed throughout the nineteenth century, was replaced at the turn of the twentieth century by the novel developmental model, which arose in the first decades of the 1900s and was later systematised by Piaget, Spock, etc. The medico-hygienist model revolved around core…

The introductory chapter clarifies key terms and lays the background for different theories of moral development. Chapter 2 surveys competing models from various schools of thought on the initial origins of morality in childhood. The works discussed include those of Freud, Jung and Piaget. Chapter 3 includes: Erik H. Erikson's sociocultural…

Adult development theorists believe that the changes that occur during the adult years are predictable and age linked. Their theories explain how change is resolved by the majority of the adult population. Three persons whose research has been influential in the field of adult development during the 1970s are Erik Erikson, Daniel Levinson, and…

This paper explores the developmental changes in meaning and purpose across the life course. Thirty males and females at the developmental stages of young adulthood (16-29 years), early middle-age (30-49 years), late middle-age (50-64 years), young-old (65-74 years) and old-old (75+ years) completed the Reker and Peacock (1981) Life Attitude…

This study examined the transition from concrete to formal operations in very bright children in an effort to determine whether high ability in concrete operations would carry over into formal operational ability, and also to investigate precocity in regard to formal operations. Subjects were 38 white middle-class children ranging in age from…

The conceptual views of homeostasis held by students (n=300) in seventh grade life science, tenth grade biology, and college zoology were examined. A biographical questionnaire, the results from two Piagetian-like developmental tasks, and a concept evaluation statement of homeostasis were collected from each student. Understanding of the concept…

Jean Piaget's belief that children's developmental levels largely determine what they can learn is challenged. Research concerning the existence of cognitive structures in children is critiqued, and problems with administering Piagetian tasks are pointed out. Educators should not restrict children's exposure to learning because, according to…

Classroom meetings are an important way to meet the demand of developmental guidance that guidance and counseling "is for all kids." Classroom meeting experiences help students cope and deal with their lives by providing opportunities for self-awareness and self-affirmation. (Author)

Little attention has been given to how adults develop through their lifetimes and what roles their workplace environments play in that development. Research and theory regarding adult psychosocial development have confirmed the developmental life-cycle phases of adulthood. These are: leaving the family (ages 16-22), getting into the adult world…

This study investigated young children's ability to solve probability problems and studied the cognitive processes proposed by Piaget and Inhelder as necessary to solve probability problems. The effects of tutorial and self-discovery training were measured and discussed. Results from 168 first-graders in five training conditions indicated that:…

Research is described concerning a factor analytic view of adolescent thought in Piagetian context. Included are a description of Piagetian tasks used for determining stage of mental development, studies concerning Piagetian task factor analysis, and the current factorial structure of adolescent thought.

Challenges adult educators to provide the educational experiences and resources necessary for adults to handle life tasks. Introduces the "teachable moment", as part of a lifelong curriculum, which relates the tasks associated with each developmental life stage to appropriate adult education program responses and possible outcomes. (TP)

Reviews the history of human development, and of family development and its interdisciplinary nature. Explores variations as well as the universality of the family life cycle and developmental tasks. Presents examples of the applications of family developmental concepts by a variety of practitioners in the family field, offering ideas on research…

This is the first study to investigate experimentally how children come to learn mappings between novel phrasal forms and novel meanings: a central task in learning a language. Two experiments are reported. In both studies 5- to 7-year-old children watched a short set of video clips depicting objects appearing in various ways. Each scene was…

Part of a prospective longitudinal study examining factors that account for developmental outcomes for high-risk children, this investigation focused on how successful adaptation at 12 and 18 months is related to adaptation at 24 months, 42 months, and 4.5 to 5 years of age. Assessments at each age were designed to indicate how the child was…
