Self-directed weight control through eating and exercise

A weight control program using a written contract and other self-control behavior modification techniques for changing eating habits was compared with a similar program concentrating on both eating and exercise behavior and with an attention-placebo control condition. Participants in all three programs lost weight during the 12 week program, with no significant differences between groups. A seven-month follow-up revealed that Ss in the two behavior modification groups lost more than those in the control group and that those in the eating plus exercise group lost more than those in the group dealing only with eating behavior.     

On the form of learning curves

In a wide variety of learning experiments, cumulated measures of performance turn out to be a power function of practice time or number trials, typically with an exponent between 1 and 2. The effects of various conditions on the course of learning can frequently be described in terms of the two constants of the function.     

Achieving Subjective Well-Being Around the World: The Moderating Influence of Gender,Age and National Goals for Socializing Children

We propose that one’s subjective well-being (SWB) arises from the satisfaction of one’s basic needs, but that the importance of attaining specific needs will vary according to one’s gender, age, and national culture. We argue that the role of one’s national-cultural background in that process can best be unpackaged in terms of the emphasis of a nation’s citizens on the goals for socializing children, namely, self-directedness versus other-directedness and civility versus practicality. Accordingly, we analyzed the responses of 65,025 persons across 50 nations to questions on the World Values Survey about their perceived state of health, financial satisfaction, trust of in-group members, and sense of personal control over events. Using HLM analysis, we showed that all four factors were significant predictors of SWB pan-nationally, but that the linkages of financial satisfaction and trust of in-group members to SWB were moderated by a nation’s self-directedness and civility; those of financial satisfaction and health were moderated by age. These results indicate that the socialization emphases characterizing one’s national culture operate to make some of the key contributors to one’s SWB more or less predictive. Cross-national studies are thereby vindicated in their capacity to reveal nation-specific formulas for psychological processes leading to SWB.     

Effects of a Peer-Delivered Corrective Reading Program

The effects of a peer-delivered Corrective Reading program (CRP) (Engelmann, Hanner, & Johnson, 1989) with repeated reading on the reading performance of at-risk high school students were examined. High school peer instructors and students in need of reading remediation were randomly assigned to dyads or triads. Peer instructors presented the CRP, conducted repeated reading trials, and took rate and accuracy measures. Pre to post test data were collected on vocabulary and comprehension subtests of the Gates–MacGinitie Reading Tests, oral reading fluency (words read per minute) and accuracy, number of repeated readings on initial and final lessons, and lessons completed. Results indicated that students' performance on the standardized reading assessment increased as did their oral reading fluency. In general, the number of repeated readings decreased from the initial lesson to the final lesson. Implications for further research are discussed.     

Procedural Justice and Perceptions of Fairness in Selection Practice

Demonstrating procedural justice through a focus on the psychometric job-related approach to selection continues to be the most effective means for employers to meet legal requirements and potential claims of unfair treatment. A study of selection practice in a large local UK City Council reports how a structured, highly ‘job-focused’ approach can result in negative perceptions about the fairness of the process, its outcomes and effectiveness. Its findings reveal an organizational dilemma – how to develop selection systems that are sufficiently robust in terms of demonstrating maximum procedural fairness and objectivity to withstand potential litigation but are sufficiently flexible to accommodate those other factors which influence individual perceptions of fairness. It considers the future of the highly structured approach in the light of pressures to develop selection processes which can meet the needs of rapidly changing organizational structures as well the expansion of anti-discrimination legislation and litigation.
