This review focuses on the effects of multiple contacts with respondents on studies of response rates to mail surveys. After screening articles on research criteria, such as the presence of original research and sufficient reporting detail, 28 studies remained of the original 208 identified. The difference in response rate between treatment and…

The effects of conditions of informed consent and disclosure on the performance of 84 students doing a statistics laboratory assignment for an introductory graduate course in statistics at a state university in the southeast were studied. Four separate classes taught by three instructors were included. Subjects ranged in age from 22 to 47 years,…

Problems associated with the analysis of data collected using the Solomon Four Group Design are discussed. The design includes an experimental group and a control group that have been pretested and posttested, and an experimental and a control group that have been posttested only. A sample problem is approached in three different ways. First, the…

THE ACHIEVEMENT OF ALL BEGINNING AND ADVANCED SHORTHAND STUDENTS USING TRADITIONAL SHORTHAND TEACHING DURING 1964-65 WAS COMPARED WITH THAT OF ALL BEGINNING AND ADVANCED SHORTHAND STUDENTS USING THE FOUR-CHANNEL STENOGRAPHIC LABORATORIES AND A LOCALLY DEVELOPED 440-TAPE LIBRARY DURING 1965-66. IN BEGINNING SHORTHAND, 1,596 STUDENTS STARTED AND…

THIS EXPERIMENT WAS DESIGNED TO INVESTIGATE (1) THE AMOUNTS OF INFORMATION COMMUNICATED BY THE KNOWLEDGE OF A PRINCIPLE AS OPPOSED TO THE KNOWLEDGE OF CUES AND (2) THE EFFECTIVENESS OF THE KNOWLEDGE OF A PRINCIPLE AS OPPOSED TO THE KNOWLEDGE OF CUES AT DIFFERENT STAGES OF LEARNING. THE FOUR GROUPS MAKING UP THE EXPERIMENTAL DESIGN WERE A CUE GROUP…

Linear classification functions (LCFs) arise in a predictive discriminant analysis for the purpose of classifying experimental units into criterion groups. The relative contribution of the response variables to classification accuracy may be based on LCF-variable correlations for each group. It is proved that, if the raw response measures are…

THE PURPOSE OF THIS PROJECT WAS TO IDENTIFY KINDERGARTEN PUPILS WHO, WHEN COMPARED WITH OTHER CHILDREN OF THE SAME AGE AND SEX, EVIDENCED PROBLEMS IN THE AREA OF VISUAL PERCEPTION. TESTS USED TO MEASURE SUCH DEFICIENCIES WERE THE BENDER TEST AND THE FROSTIG TEST OF VISUAL PERCEPTION, SUB-TEST I AND III. MATCHED PAIRS WERE SELECTED FROM THE TOTAL…

Marathon groups offer individuals an opportunity to engage in intensified, authentic personal encounter with each other in a small group setting, usually with 10-15 persons in a group. This is a report of tentative findings at the Student Life Center, University of Colorado. There were three matched groups, each with nine sophomores. The first…

Systematic Desensitization (S. D.) training, which has been successfully used both individually and in small groups to reduce people's communicative anxiety, must eventually be applied in large training groups to be economical and efficient. In large heterogeneous group work, however, it is important to determine the possible detrimental effects…

Investigated were the effects of test anxiety, success-fail experiences, and social reinforcement on the aspiration level of third and fourth grade subjects (Ss) in a suburban school system. Data were sought on whether high test anxiety (HTA) children would have lower aspiration levels than low test anxiety (LTA) children. Also studied were the…

A history of the people's theatre movement in this country from the early 1920s to the early 1970s, this book deals with the structural and thematic connections between the radical theatre of the twenties and thirties and current work of such revolutionary theatres as the Living Theatre, Open Theatre, Bread and Puppet Theatre, El Teatro Campesino,…

It was the purpose of this study to determine the effectiveness of developing auditory discrimination skills in kindergarten children through a series of 24 lessons prepared by the investigator and deemed appropriate by kindergarten teachers. The effect of the auditory discrimination lessons on listening habits and attitudes was also examined.…

This investigation was designed to shed light on the study of literature by focusing on the reader's affective understandings and by using the semantic differential (S.D.) to measure affective meaning. Initially, an experimental group of 49 advanced senior high school students and a comparison group of 53 average senior high students used the S.D.…

Two experiments were performed to evaluate the effects of modeling and small group activities on language and cognitive change in samples of young, low socio-economic status (SES) children. Experiment I involved children attending two preschool centers for aid to dependent children. Experiment II took place in the context of a research preschool…
