This paper provides a descriptive overview of research on the consequences of overcrowding and the development of high population densities in animals, and speculates on the relevance of these studies for similar human phenomena. Three major foci are distinguished: (1) the effect of high population densities on animal behavior; (2) the nature of…

As part of a larger study, the nature of the teacher-child relationship was examined in a random sample of 50 day care centers in Los Angeles County. Data were obtained by observation of teacher-child interaction and supplemented by interviews with directors and teachers. The groups of variables examined were: teacher performance, structural…

In this research competition is examined conceptually in order to develop a functional definition that will facilitate systematic research on the process. Competitive behavior is defined as behavior that is a positive function of a comparison of the results of one person's behavior with the results of another's behavior. Comparisons, in turn, can…

Most of the research summarized in the report centers around cross sectional differences among representatives of different belief or personality systems.

THE EFFECTS OF SPECIFIC OPERANT AND MODELING PRINCIPLES ON INCREASING ATTENTIVE (TASK-ORIENTED) CLASSROOM BEHAVIOR OF HYPERACTIVE CHILDREN WERE STUDIED. THE METHODS OF BEHAVIORAL MODIFICATION USED IN THE STUDY WERE DISCRIMINATION-MODELING AND OPERANT CONDITIONING. SUBJECTS WERE 24 STUDENTS FROM GRADES 1 THROUGH 4 WHO WERE JUDGED HYPERACTIVE BY…

This study examined the effects of different degrees of task structure on leadership between 18 married parents, 18 childless married spouses, and 18 unmarried men and women who comprised newly acquainted couples. Each couple completed three tasks which varied along the dimension of task structure and the order of task presentation. Analysis of…

Two five-week test-retest reliability studies of a measure of the unit of perception of ongoing behavior were conducted. In the first, 25 females and 23 males segmented a 7-minute action sequence under fine-unit or gross-unit instructional sets. Number of units marked at first viewing correlated .87 with number of units at retest. Correlations…

The information gathered in this study was put into practical use in Atlanta by making recommendations to a public service agency that through working with several governmental agencies, is in the process of organizing and ascertaining funds for a newspaper in Spanish for the metropolitan area.

Three experiments were conducted in a variety of settings to test the effectiveness of differential reinforcement of other behavior in reducing high rates of inappropriate behavior in 6 mildly and severely retarded children (8-14 years old). (Author/CL)

This study examined the effects of body image boundaries on preferred and avoided seating choices in small groups and the personal meanings associated with these measures of spatial behavior. The findings indicate a tendency toward greater defensive distancing by the boundary-indefinite subjects. (Author)

A 13-year-old congenitally blind black girl was involved in a study designed to demonstrate the effectiveness of a longitudinal behavior modification approach in extinguishing "blindisms" (persistent autistic-like behaviors) in a variety of settings. (SB)

Studies the ways in which information disclosed early in a relationship is used to form predictions about probable attitudes of the other person, and subsequent communication behavior as the relationship progresses. (MH)

Low income classrooms demand that teachers supervise and monitor students' seatwork actively and control private interactions with students. Praise and a relaxed climate are more important in low than high income settings. (JD)
