Repeated Behavior and Environmental Psychology: The Role of Personal Involvement and Habit Formation in Explaining Water Consumption1

Extending existing theory in social and environmental psychology, we develop a model to study important predictors of water consumption behavior. Overall results provide support for the predictive ability of stimuli (e.g., environmental awareness), reasoned processes (e.g., personal involvement), unreasoned processes (e.g., habits), and situational factors (e.g., income) on water consumption behavior. Findings indicate that households with lower water usage display greater awareness of water conservation issues, are more highly involved in the decision to use water, and tend to form habits associated with lower usage levels. Furthermore, the results are consistent with past research that attitudes toward water usage appear to be poor predictors of water consumption behavior. After controlling for situational factors (e.g., household size), the findings substantiate the role of personal involvement and habit formation in explaining water consumption, lending further support to the adaptation and development of repeated behavior models in environmental psychology.     

Binding feature dimensions in visual short-term memory

We explored several possible influences on binding in visual short-term memory (VSTM) performance. The task was to report whether a test object was the same (“old” trials) or different (“new” trials) from any of the sample objects seen a second ago. The objects were composed of two features that varied from continuous to discrete shapes and colors. In “old” trials the test object appeared either in the same or different position. In “new” trials the test object differed along both features, requiring storage of only one feature per object; along one feature, requiring no binding but storage of all features; or it was created by recombining features from the sample, which requires binding. Existing storage hypotheses are unable to explain the similar sensitivity (d′) obtained in the two last conditions when position remained the same and may suggest that links are created between positions and features. Highest sensitivity occurred when the test object remained at the same position, required no binding, and discrete features were used. Object-type × position, and feature combination × position interactions occurred, suggesting different storage modes depending on whether objects change position during retention.     

A project to strengthen linkages between genetic centers and child welfare services

Genetic centers are reaching out to underserved populations. One of the most vulnerable underserved populations is children receiving child welfare services. Delivering genetic services to this group is particularly problematic because of multiple barriers. The first step in overcoming barriers is developing linkages between the genetic and adoption service systems with the goal of increasing referrals of child welfare clients to genetic services. This paper presents a model of fostering linkages that was developed under the auspices of the Mid-Atlantic Regional Human Genetics Network with support from the Maternal and Child Health Bureau, Genetic Services Branch. Although the project was regional and funded, the model can be applied at the local level.     

Gender typing,importance of multiple roles,and mental health consequences for women

The present study examined the interactive influence of gender role typing and multiple role involvement with regard to specific mental health concerns among middle-class Caucasian women. As with previous research, depression and anxiety proved to be a function of gender role typing (feminine-typed and undifferentiated women displayed greater depression and anxiety relative to masculine-typed or androgynous women) with no differences attributable to multiple role involvement. For substance abuse, however, an interaction effect was obtained. Gender-typed (both masculine and feminine) women striving to excel across multiple roles engaged in greater substance abuse than women not gender typed (androgynous and undifferentiated); indeed, the latter displayed low risk comparable to women not similarly striving at multiple roles regardless of gender typing. A similar interaction previously has been reported with regard to disordered eating. These findings suggest that the lack of gender typing for women may enable them to cope more effectively with the conflicting demands of multiple roles and thereby reduce certain health risk behaviors (e.g., disordered eating and substance abuse), but that other mental health concerns (e.g., depression and anxiety) may not be similarly affected.     

An examination of practice effects in recognition

A study of practice effects in recognition performance is reported. In each of two experiments, different conditions of training were followed by a critical final test. In Experiment 1, a yes-no procedure was used on the critical test. During the training phase, some subjects were tested by the same method, either with or without item-by-item feedback, whereas others were given forced. choice tests. No significant changes in recognition accuracy were observed, either during the training trials or on the final test. However, feedback and experience with forced-choice tests both served to increase the bias toward positive responding. In Experiment 2, the forced-choice procedure was used on the critical final test. Either forced. choice tests or yes-no tests were given on the training lists. Again, there were no significant changes in performance. The absence of practice effects is attributed to the difficulty of identifying and implementing test-appropriate strategies.     

The Proofs Of The Grundgedanke In Wittgenstein's Tractatus

The Tractatus contains twodifferent proofs of the Grundgedanke, or thenonreferentiality of logical constants. In thispaper, I explicate the first proof in TLP 5.4s andreconstruct the less explicitly stated second proof. My explication of the first proof shows it to beelegant but based on an invalid inference. In myreconstruction of the second proof, the main argumentis that the sign of a logical constant does not denotebecause it possesses the punctuation-mark-nature. Andit possesses the punctuation-mark-nature because,given the analyticity thesis in TLP 5, one canestablish for everyday language an adequate symbolismwith N as the sole fundamental operation such that itssign is a bar indicating merely the order and scope ofits application.     

A theoretical frame of reference for family systems therapy? An introduction to Luhmann's theory of social systems

The starting point for this paper is that family therapy lacks a theoretical frame of reference of its own; thus a stepwise search for such a frame of reference is described. First, social systems are defined as communication systems. Second, it is shown in what way a family can be seen as a social system. With the help of the theory of social systems of the sociologist Luhmann, a theoretical frame of reference for systems therapy is drafted. Finally, we hint at the implications such a theoretical framework could have for clinical practice.     

Socrates questions Gorgias: The rhetorical vector of Plato's “Gorgias”

This essay argues that Plato's Gorgias, a dialogue lauding dialectic over rhetoric, uses a question-and-answer format as a heuristic of argument. Specific observations are advanced to explain the implications of Plato's techniques and to provide a more sensitive understanding of the process by which sought to gain the adherence of his readers.
