While Jean Piaget's work as it relates to the development of childhood and adolescent cognition has long been explored, only recently has the usefulness of Piaget's theory in the study of adult cognition been studied. Recent research by educational psychologists has raised serious doubts about Piaget's theoretical position that the highest level…

This paper is a first report from the project "Activity Learning and Cooperation," financed by the Swedish Board of Education. The aim of the project is to establish a theoretical basis for a field study of locally initiated experiments using various teaching strategies. More specifically, this paper is restricted to a discussion of the…

The purpose of this review is to examine findings concerning the effects of day care on psychosocial and cognitive development. Studies are grouped into two broad categories: (1) the effects of day care on the mother-child relationship; and (2) other psychological outcomes. Only a few studies have found evidence that day care negatively affects…

Since adults are socializing agents integral to home and school settings, they should have accurate views of children's feelings. Adults' (N=96) predictions were compared to the predictions kindergarten children (N=32) made about the children's affective responses to eight different categories of experiences. The children's predictions, reported…

This paper describes an assessment instrument being developed to trace the emergence of social-communication skills leading to language and the neo-Piagetian model that is directing the assessment construction efforts. The model is a structural stage model, based on the writings and research of Uzgiris (1976), McCall, Eichorn & Hogarty (1977),…
