This paper briefly reviews how subjects enhance performance by favoring some stimuli over others. The author calls the mechanism by which this is achieved "expectancy", a generic term including preparatory set, behavioral hypotheses, orienting reflex, and anticipatory goal responses. Temporal and event expectancy are contrasted. Verbal prediction…

Discusses five ways to make goal setting effective: set difficult and specific goals, monitor results, reward performance, participate in goal setting, and challenge individual self-confidence and goal dissatisfaction. A model showing internal and environmental factors related to performance and a list of management strategies for enhancing…

Explores the rationale for the creation of the rumor control center and identifies the few valuable models found in the literature. Examines the usefulness of the center as an additional channel of communication and considers the desirability of using such a mechanism. Suggests an approach to teaching rumor control. (JMF)

Quantitative analyses of stimulus control and reinforcer control in conditional discriminations and delayed matching-to-sample procedures often encounter a problem; it is not clear how to analyze data when subjects have not made errors. The present article examines two common methods for overcoming this problem. Monte Carlo simulations of…

Insects are a natural choice for studying behavioral ecology in the classroom--they are easy to obtain, maintain, and manipulate. Unlike competition and predation, however, the concept of group living does not translate well to small-scale experiments involving only a few individuals. How can inquiry be used to examine why animals live in groups?…

TgCRND8 mice represent a transgenic mouse model of Alzheimer's disease, with onset of cognitive impairment and increasing amyloid-[beta] plaques in their brains at 12 weeks of age. In this study, the spatial memory in 25- to 30-week-old TgCRND8 mice was analyzed in two reference and one working memory Morris water maze (MWM) tests. In reference…

The impact of a previously successful or unsuccessful experience on the subsequent acquisition of a related task is not well understood. The nature of past experience may have even greater impact in individuals with learning deficits, as their cognitive processes can be easily disrupted. Mice with a targeted disruption of the [alpha] and [delta]…

Extending the work of behavioral scientist Urie Bronfenbrenner on the social and contextual factors influencing human development, this collection of essays, from scholars in a range of disciplines, shows how Bronfenbrenner's ecological theory and research have transformed the way many social and behavioral scientists approach, think about, and…

This summary of methods for improving the user-computer interface is based on a review of the pertinent literature. Requirements of the personal computer user are identified and contrasted with computer designer perspectives towards the user. The user's psychological needs are described, so that the design of the user-computer interface may be…

This volume contains 20 essays on current research in representative areas of psychology. The authors are professors and researchers at universities in the United States, England, Colombia, Poland, Australia, the Netherlands, France, and Canada. A wide range of topics is discussed. Included among these are social psychology of intergroup…

Classification of current group therapies by three main criteria provides a useful conceptualization of why therapy is sometimes difficult to distinguish from the NTL-model T-group. The appropriateness of sensitivity training based on the criteria of "client normality" identifies several perspectives, including the futility and inadvisability of…

A comparative analysis of two decision making strategies was conducted. One strategy compared alternatives on their best attributes for "the best payoff," while the other strategy called for accepting the first alternative that achieved all minimum cutoff values for all attributes. The subjects, 211 college students, selected a mayoral preference…

A phenomenological approach to library research utilizing qualitative research methods is contrasted to a positivist-behaviorist approach utilizing quantitative methods. Psychological understanding of a situation attained by means of accurate description, and subjectivity and associated intentionality are presented as part of the phenomenological…

It is difficult to account for the real and easily measured differences in verbal competence. Differential psychologists investigate basic traits from which observed behavior is thought to be generated, but if thinking is viewed as a problem in information handling, research will more profitably focus on the relationship between behavior in…

The purpose of the paper is to present a model and suggest hypotheses relating the family as a social system to the concepts of human and natural energy. Human energy is interpreted as the capacity of humans, in this case, family members, for doing work and natural energy as resources such as natural gas, carbon dioxide, and heat. A behavioral…
