Frequency of aggression in 5- to 8-year-old children was examined in relation to frequency of helping, comforting and sharing. Subjects (39 boys and 40 girls attending a summer day camp) were each observed for two hours and their aggressive and prosocial behaviors recorded. This study differed from previous investigations of this issue in two…

The conditions of day care quality under which infants direct secure attachment behaviors toward their day care providers were examined. Two groups of 12- to 18-month-old infants, who were experiencing either 1:4 or 1:7 caregiver-to-infant ratios, and their day care providers, were observed while they interacted in their day care centers.…

This study was designed to test two major hypotheses: (1) Validity of expectation is an increasing monotonic function of development. (2) Invalidity of expectation is more a function of overestimation of hedonistic tendencies than a function of underestimation. A total of 277 middle class children in the first, fourth, and fifth grades were given…

This paper presents a model workshop focused on sex-typed behavior and developmental psychology, which is designed to examine the major theories based on biology, socialization or a complex developmental process. The materials concentrate on the three main theoretical approaches underlying the development of sex-role behaviors, i.e.,…

In order to investigate developmental trends in the sex differences of two dimensions of proxemic behavior, distance and shoulder orientation, 406 elementary and junior high school students were studied while interacting in same-sex and heterosexual pairs. After engaging in discussion for one minute, the pairs were asked to stop and hold still…

Sex difference research has been plagued with a myriad of problems,. Specifically, intelligence testing, if dependent on measurement of spatial or verbal proficiency, may not be an accurate indicator of native ability. Similarly, infrequent replication of studies, studies that only include subjects of one sex yet imply sex differences, and poor…

The goals of the study were: (1) to determine the relationships among selected sociological, health, and behavioral variables and third-grade word analysis test scores, and (2) to test a causal model employing part analysis. Subjects were 314 Head Start students in 1968. Data on race, sex, perinatal complications, number of children in the family,…

This study investigated the connection between self-disclosure and stages in development of interpersonal relationships. It hypothesized that self-disclosure in relationships is of a dynamic character which works in two directions: towards the interaction partner, and in the opposite direction. The study proposed three stages in the development of…

Adolescent determination of behavior can be viewed as the result of perceived locus of control. To investigate adolescent perceptions of control in terms of age, loci of control (internal or external), situations (community and home), and direction of control (from or over the environment), 909 adolescents (345 males, 564 females), aged 11-19,…

For the individual, gender difference falls along the feminine-masculine continuum with strong neurodevelopmental influences at various points throughout the lifespan. Neurodevelopmental influences are conceptualized in a vector model of sex difference. Vector attributes, direction and magnitude, are influenced initially by differences in levels…

A study was conducted to examine the effects of child abuse and neglect on children's nonverbal behaviors. It was hypothesized that abused and neglected children would be less active nonverbally than would control group children. Eight abused and neglected children, aged one through three years, were videotaped interacting with their caregivers in…
