The effects of videotape modeling and daily feedback on residential electricity conservation, home temperature and humidity, perceived comfort, and clothing worn: Winter and summer

Two studies were conducted in all-electric townhouses and apartments in the winter (N = 83) and summer (N = 54) to ascertain how energy conservation strategies focusing on thermostat change and set-backs and other low-cost/no-cost approaches would affect overall electricity use and electricity used for heating and cooling, the home thermal environment, the perceived comfort of participants, and clothing that was worn. The studies assessed the effectiveness of videotape modeling programs that demonstrated these conservation strategies when used alone or combined with daily feedback on electricity use. In the winter, the results indicated that videotape modeling and/or feedback were effective relative to baseline and to a control group in reducing overall electricity use by about 15% and electricity used for heating by about 25%. Hygrothermographs, which accurately and continuously recorded temperature and humidity in the homes, indicated that participants were able to live with no reported loss in comfort and no change in attire at a mean temperature of about 62 degrees F when home and about 59 degrees F when asleep. The results were highly discrepant with prior laboratory studies indicating comfort at 75 degrees F with the insulation value of the clothing worn by participants in this study. In the summer, a combination of strategies designed to keep a home cool with minimal or no air conditioning, in conjunction with videotape modeling and/or daily feedback, resulted in overall electricity reductions of about 15% with reductions on electricity for cooling of about 34%, but with feedback, and feedback and modeling more effective than modeling alone. Despite these electricity savings, hygrothermograph recordings indicated minimal temperature change in the homes, with no change in perceived comfort or clothing worn. The results are discussed in terms of discrepancies with laboratory studies, optimal combinations of video-media and personal contact to promote behavior change, and energy policies that may be mislabeled as sacrificial and underestimate the effectiveness of conservation strategies such as those investigated in these studies.     

Correspondence between saying and doing: Some thoughts on defining correspondence and future directions for application

Israel (1978) evaluated and discussed research on positive and negative verbal-nonverbal correspondence. In the present report we attempt to delineate the relationship of correspondence training to two major intervention goals-producing (increasing) behavior and inhibiting (decreasing) behavior. The concepts of noncorrespondence and generalized positive correspondence are introduced. Past research relating to the correspondence analyses offered for the two intervention outcomes and possibilities for future research are discussed. The relationship of verbal correspondence training to the issues of response maintenance and response generalization is also examined.     

Age differences in the temporal locus of memory organization in children's recall

Age differences in when (i.e., at input or output) children organize information for recall were investigated in terms of a model specifying that information organized at input is more resistant to forgetting over time than information not organized at input. In Experiment 1, recall of items from categorically related and unrelated lists was assessed either immediately or after a 4-min delay. For 9-year-olds, the effect of delay was comparable for the related and unrelated lists, indicative of spontaneous organization at time of output. In contrast, 13-year-olds showed a significantly smaller delay effect with related than with unrelated lists, indicative of spontaneous organization at time of input. Experiments 2 and 3 demonstrated that, for 9-year-olds, high levels of clustering in and of themselves do not eliminate effects of delayed testing characteristic of output organization, and that when 9-year-olds are biased to organize information at input, delay effects are reduced only when measures are taken to ensure that all the category labels are retrieved.     

Foundations of risk measurement. II. Effects of gains on risk

This paper presents the second part of a two-part study on axiomatizations of perceived risk. The first part (P. C. Fishburn, Foundations of risk measurement, I. Risk as probable loss. Mimeo., Bell Laboratories, 1981) focussed on risk as probable loss. The second part considers measures of risk that include effects of gains on perceived risk. It adopts the position that increased gains can reduce the risk of fixed probable losses without completely negating this risk. Moreover, every prospect that has no chance of yielding a loss is presumed to have no risk. Several numerical measures of risk are axiomatized. The more specialized are separable in gains and losses. Further specializations isolate the effects of loss and gain probabilities.     

Psychological research on videotex

Videotex is considered to be a powerful, but simple to use, computer network available for use in homes, offices, and schools. Information in the form of text and color graphics can be requested and displayed on the user’s television set. While retrieval of information is the first service provided on videotex, many other services, including electronic mail, electronic shopping, and electronic funds transfer, will be developed. However, in order to achieve the popularity predicted for videotex, a number of human factors and social problems must be solved. Research concerning some of these problems, and the role psychologists can play in their solution, is described.     

Computer-managed inferential statistical analysis of EEG data

Much of the neuroelectrical/psychophysiologic research of the past has involved the use of “group-type” statistics. Often, this has resulted in large variances that make it difficult, if not impossible, to find significant differences. Using the INNOVATE technique of single-subject design, we are able to consistently demonstrate significant differences in EEG spectra related to experimental and clinical effects previously masked.     

Constant errors donot occur in the matched reproduction of angles

MacRae and Loh (1981) reported that when observers attempt to match angles, whether simultaneously or successively, and regardless of whether the angles have the same orientation or not, acute angles generally are set too large and obtuse angles, too small. Without presenting data, they argued indirectly that starting-position effects in their adjustment procedure could not have accounted for the errors. In four experiments, we have demonstrated that effects similar to MacRae and Loh’s do occur when their starting positions are used and that no such effects occur when psychophysical methods that minimize or eradicate starting position effects are used.     

A group behavior modification approach to adolescent obesity

This article describes a group weight control project with severely obese adolescent girls in a medical setting. Behavior modification and nutritional principles were utilized with peer group interaction. Significant others were included through separate group meetings. This approach produced small amounts of net weight loss for the girls. The drop-outs continued to have a net gain. As a treatment method, this program was more effective for these girls than previous individual clinic contacts had been. When losing weight, the girls tended to use behavior modification techniques more often, and their diets became more adequate nutritionally. Development of group cohesion was tenuous and temporary. Girls who were functioning more independently appeared to do better in weight loss. Disinterested significant others were preferable to nonsupportive ones. A predictive factor was identified, the girls' perception of control. This was measured by the I-E test. Those with a more internalized perception of control were more likely to continue with the program and more likely to lose weight. Because the patient group was small, findings are tentative. However, this program helped to define particular areas that deserve further exploration.     

Maintaining patients' improvements in a token economy.

Eighteen long stay male patients (diagnosis chronic schizophrenia) were involved in a six month token economy prior to random assignment to one of three experimental groups to investigate the importance of social reinforcement and other token-related variables in maintaining improvements brought about by the token system. Assessment included standardised psychiatric rating scales, nurse rating scales, and behavioural measures. Analysis of variance suggests the full token economy system produced significant improvements, but that the social factors involved in token exchanges were not demonstrably important sources of reinforcement. and that none of the variables studies at the experimental phase were critical factors. Once patients returned to a complete token system, results indicate that this may have more value in the promotion of work activities rather than social responding. It is argued that the token system provides a necessary clear structure within which nurses can encourage continuous improvements with long stay patients.
