This document presents Part I of a two-part study which sought to ascertain the relationship of grade level, achievement level, sex, and method of presentation to the various bases by which children classify geometric concepts. Two tasks, administered consecutively to 96 subjects in grades five, eight and eleven, consisted of the sequential…

This document, Part II of a two-part study, is the summary chapter of a report which sought to ascertain the relationship of grade level, achievement level, sex, and method of presentation to the various bases by which children classify geometric concepts. Two tasks, administered consecutively to 96 subjects in grades five, eight, and eleven,…

The influence of age, sex, representational detail of objects (prototypicality) and adult play suggestions on children's progression of pretend behaviors was studied. A checklist was developed and utilized for coding the responses of 20 children (10 males, 10 females), to objects judged to be high and low prototypical by 12 adults. Children ranged…

An experiment was performed to show that infants perceive auditory and visual stimuli within a common space and that they perceive the sound as an attribute of the visual object. Subjects were 22 infants aged 3 to 5 months. Each infant was presented with a toy that moved in a small arc from side to side of a small window at the rate of one arc per…

Examined effects of presentation of a peer-in-need stimulus to preschool children in real versus hypothetical contexts, with results indicating a significantly higher incidence of helping behavior in real situations. Nature of helping response as a preoperational reaction to concrete contextual cues is verified. (Author/DST)

Reviews research focusing on problem-solving deficits and their relationship to suicidal behavior and considers some of the methodological problems that arise. Discusses findings in terms of active versus passive problem solving, state or trait factors, and the psychological processes underlying problem solving. (Author/JDM)

Evidence which suggests that pretend activities become increasingly independent of the presence of realistic objects is examined in this paper. Results of research on pretend behavior in children 1 1/2 - 2 years of age are described and analyzed. Striking changes in pretend behavior are shown to occur during the second year of life. Pretend play…

This study examines the degree to which young children are influenced by the familiarity of an adult participant in their pretend play with toys which vary in resemblance to highly prototypical objects (e.g., cup-like cups or doll-like dolls). A group of 29 children, mean age 21 months, was divided into two experimental groups balanced by sex; 15…

This report summarizes four components of a research program. In the major investigation (Study 1), a method was developed for making bimodal presentations of discrepant auditory and visual stimuli under conditions which approximately early academic tasks. The goals were to determine (1) which stimulus modality exerts the greater influence on a…

Human development from about ages 2 to 5 is presented in terms of the history of a child conceptualized in terms of stimulus and response functions and his interactions in current situations which consist of organismic, physical, and social conditions. The concepts describing the changes that occur during this developmental period, such as…

THE BEHAVIORAL NORMS OF LOWER CLASS DISADVANTAGED CHILDREN ARE DIFFERENT FROM CHILDREN IN MORE MIDDLE CLASS GROUPS. THE BEHAVIOR OF LOWER CLASS CHILDREN IS INFLUENCED NOT ONLY BY GENERAL SOCIAL CLASS AND CULTURAL BACKGROUND BUT ALSO BY SUCH SPECIFIC INTRACLASS VARIABLES AS FAMILY ENVIRONMENT. THE PRESENT ABSENCE IN THE LITERATURE AND IN PRACTICE…
