Control subjects completed Book IV of the Edwards Personality Inventory under instructions to be honest while experimental subjects were instructed to fake so as to make an excellent impression while also concealing their faking. Differences between group means were small. (Author/EK)

The effects of in-service training programs on their participants are evaluated. (CK)

The relationship between children's social adjustment and their ability to read is discussed. (CK)

A problem for program evaluators involves a search for ways to maximize internal validity and inferential power of research designs while being able to assess long-term effects of social programs. A multimethodological research strategy combining a delayed control group true experiment with a multiple time series and switching replications design…

Rationale and procedures for conducting process analysis in evaluation research are discussed. Two different procedures for estimating mediation are discussed, as well as procedures for examining whether a treatment exerts its effects, in part, by altering mediating process that produces outcome. Benefits of process analysis in evaluation research…

CUTOFF is a program to identify the most efficient classification prediction cutting score. It ranks the scores of a criterion and a comparison group and organizes them into cumulative frequency tables allowing for immediate display of an index of correct identifications associated with each score. (Author/JKS)

Establishes a theoretical foundation for control groups; defines four types of control groups applicable to HPT (human performance technology) program evaluation and measurement; explores their validity; and presents scenarios for an electronic learning program to demonstrate the applicability of the control group methods for HPT program…

Explores the possibility of randomly assigning groups (or clusters) of individuals to a program or control group to estimate the impact of programs designed to affect whole groups. Applies the cluster-assignment approach to the evaluation of education programs targeting whole schools. Discusses statistical implications of the method. (SLD)

This experiment assessed the effects of "d"-Amphetamine and ethanol on reinforced variable and repetitive key-peck sequences in pigeons. Pigeons responded on two keys under a multiple schedule of Repeat and Vary components. In the Repeat component, completion of a target sequence of right, right, left, left resulted in food. In the Vary component,…

The aim of this study was to elucidate how prelingual deafness affects the ability to process written words. An experiment designed to reveal possible differences in the word-processing strategies and efficiency of a sample of prelingually deafened students (n = 18; mean grade = 5.1) and a task-matched hearing control group (n = 28; mean grade =…

Hand hygiene is a key element in preventing the transmission of cold and flu viruses. The authors conducted an experimental-control design study in 4 campus residence halls to determine whether a message campaign about hand hygiene and the availability of gel hand sanitizer could decrease cold and flu illness and school and work absenteeism. Their…

The long-term effect of two parent training programs for conduct problem preschoolers is reported. Families of 54 behaviorally disturbed preschool-aged children were randomly assigned to 1 of 3 treatment conditions: standard Parent-Child Interaction Therapy (STD), an abbreviated form of PCIT (ABB), and a no-treatment waitlist control group (WL).…

Can infants below age 1 year learn words in one context and understand them in another? To investigate this question, two groups of parents trained infants from age 9 months on 8 categories of common objects. A control group received no training. At 12 months, infants in the experimental groups, but not in the control group, showed comprehension…

This article focuses on the problems of adults who in secondary school were high ability learners. The main point of interest of the research presented here is job satisfaction among gifted people and their temperament structure. The authors are interested whether there exist correlations between the investigated variables both in the entire group…

Constructivist ideas have influenced recent major innovations in Dutch secondary education and new curricula for reading and math in primary education, for example, pay much more attention to metacognition than before. In our study, we compared the growth of student metacognition in varying learning environments, direct instruction, and cognitive…
