The effects of certain teaching methods upon the development of critical thinking skills, an understanding of science and scientists, and knowledge of subject matter were investigated. An analysis of covariance and rank correlation between teacher behavior patterns and particular student outcomes on the "Watson-Glaser Critical Thinking…

It has been demonstrated that interaction analysis is a useful tool for helping teachers not only to hold illustrations of their teaching for future analysis but also to focus on and analyze specific aspects of their verbal instructional behavior. Apparently, four conditions are necessary to enable teachers to analyze and evaluate their…

Two experiments were conducted to examine self-fulfilling expectancy influence in a simulated supervisor-worker interaction. The first experiment led supervisor subjects to expect either high or low compliance from their workers. All workers completed a set of five tasks twice, once when instructed to work fast and once when instructed to work…

This paper explores the cognitive and behavioral consequences of our impressions of other people in the context of social stereotypes. Social stereotypes are a special case of interpersonal perception. Though they are usually simple and overgeneralized, many social stereotypes concern highly visible and distinctive personal characteristics, such…

This study examines the impact of one important task characteristic for the process by which groups solve problems. The principal comparison is between a generative problem and a choice task, and whether or not the differences between these types of tasks affect the group's methods for arriving at a decision. Two types of analysis are conducted of…

The controversy about the causal ordering of leader behaviors and unit performance is reviewed. The analysis indicates that neither the behavior-performance nor the performance-behavior proponents have provided convincing evidence. A longitudinal study of the development of these interrelationships from the initial stages is described. The results…

This paper presents a new mathematical approach, fuzzy mathematics, for defining, classifying, and analyzing concepts within communications. Fuzzy mathematics is based on the premise that real world phenomena contain characteristics that overlap any artifically created category system or classification rules. Therefore, set membership is…

This report examines the relationship between maternal medication during labor and mother-infant interaction on the third day of life. Subjects were 45 black low-income mothers and their healthy full-term infants. The mothers' perinatal drug history was obtained, and a coded observational schedule was used to record maternal and infant behaviors…

This paper examines the process of intervention design as it relates to the grammar of artifactual action. In his discussion, the author identifies three separate elements of artifactual action. These elements include defining the situation of action and the change agent's relationship to the situation; generating typical expectations about…

A measure of role-taking skill was administered individually to 12 male and 8 female preschoolers. In addition the children were observed during free play on 30 consecutive school days, and their behaviors were coded according to Parten's social participation categories. Significant negative relationships were found to exist between the…

In a recent article Jensen proposed the existence of what was termed the sex x race x ability interaction in which the differences in mental ability between the black sexes were larger than the corresponding differences among whites. Three large sources of data that were analyzed failed to reveal the interaction. Since Jensen's own work suggested…

The impact of children's reactions to punishment on subsequent adult disciplinary actions was assessed in a study in which adult women administered rewards and punishments contingent on the behavior of a child viewed on a television monitor. Following an aggressive act by the target child and punishment administered by the adult subject, the adult…

Comprehensive planning, defined as the work of those who engage in efforts, within a delimited geographic area, to identify and order the physical, social, and economic relationships of that area, is discussed in the four sections of this paper. Section I, Introduction, describes what "planning" and "comprehensive planning" are. In Section II, Why…

Several models for organizing methods of observing social interaction are presented in the form of dimensions along which researchers choose methods to fulfill particular research objectives. The setting dimension specifies whether the research will be done in the lab or in the field. The output dimension specifies the form which the data will…

Fifty volunteer undergraduate students majoring in speech pathology and audiology at the University of North Dakota tested the following hypotheses: (1) leaders exhibit significantly more nonverbal cues than do nonleaders in task-oriented and informal small groups; (2) members of task-oriented small groups exhibit significantly more nonverbal cues…
