The informativeness and frequency of presentation of a social stimulus as determinants of its efficacy as a reinforcer

It was demonstrated that variations in the informativeness of a social stimulus place important limitations on the generality of the proposition that deprivation heightens, while satiation lowers, responsiveness to a social stimulus. Using 60 children 5 to 6 years of age as subjects, a social stimulus (“good”) was presented at either a high or a low frequency in one of three information-value contexts (high, medium, or low). Immediately following the exposure treatment the same social stimulus was employed as a reinforcer of nonpreferred responses in a two-choice discrimination learning task. The findings indicated that the heightened efficacy of deprivation relative to satiation only held for low information value; when initial information value was high the subsequent efficacy of a social stimulus was enhanced by its initial recurrent usage. Trend analyses revealed that the effects of variations in information value were strongest within the high-frequency-of-praise treatment. Possible mechanisms underlying the significant Information Value × Frequency interaction were discussed.     

Multidimensional letter similarity derived from recognition errors

In order to provide a reliable measure of the similarity of uppercase English letters, a confusion matrix based on 1,200 presentations of each letter was established. To facilitate an analysis of the perceived structural characteristics, the confusion matrix was decomposed according to Luce’s choice model into a symmetrical similarity matrix and a response bias vector. The underlying structure of the similarity matrix was assessed with both a hierarchical clustering and a multidimensional scaling procedure. This data is offered to investigators of visual information processing as a valuable tool for controlling not only the overall similarity of the letters in a study, but also their similarity on individual feature dimensions.     

Sexual Morality: The Cultures and Emotions of Conservatives and Liberals1

Political conservatives and liberals were interviewed about 3 kinds of sexual acts: homosexual sex, unusual forms of masturbation, and consensual incest between an adult brother and sister. Conservatives were more likely to moralize and to condemn these acts, but the differences were concentrated in the homosexual scenarios and were minimal in the incest scenarios. Content analyses reveal that liberals had a narrow moral domain, largely limited to the “ethics of autonomy” (Shweder, Much, Mahapatra, & Park, 1997) while conservatives had a broader and more multifaceted moral domain. Regression analyses show that, for both groups, moral judgments were best predicted by affective reactions, and were not predicted by perceptions of harmfulness. Suggestions for calming the culture wars over homosexuality are discussed.     

Determinants of the magnitude of willingness to accept relative to willingness to pay

In this paper we test two hypotheses that stem from the work of Mellers, Chang, Birnbaum and Ordonez ( 1992 ). The first hypothesis is that in a binary gamble, the ratio of WTA to WTP is decreasing in the probability attached to a nonzero event. The second hypothesis is that this ratio is independent of the size of stakes. We find support for the first hypothesis, but mixed support for the second. The second hypothesis holds in the case of gains, but not in the case of losses. Copyright © 2001 John Wiley & Sons, Ltd.     

The Association Between Observed Parental Emotion Socialization and Adolescent Self-Medication

The current study examined the moderating influence of observed parental emotion socialization (PES) on self-medication in adolescents. Strengths of the study include the use of a newly developed observational coding system further extending the study of PES to adolescence, the use of an experience sampling method to assess the daily covariation between negative affect and substance use, and a focus on PES styles defined by the interaction of emotion-dismissing and emotion-coaching behaviors. Using multi-leveling modeling, we tested PES as a moderator of daily negative mood-substance use relation in a sample of 65 elevated-risk adolescents (48% male, 58% Caucasian, with a median age of 14). Results showed a three-way interaction between emotion-coaching PES, emotion-dismissing PES and daily negative mood in predicting daily substance use. Results are discussed in terms of the importance of PES styles and their effects on self-medication through compromised emotion regulation and interpersonal processes.

A complex dynamic systems approach to lasting positive change: The Synergistic Change Model

This paper argues that psychological and social functioning is fundamentally complex, and that this complexity is critical to understanding how lasting positive changes can be achieved. Principles from complex systems theory are integrated into an empirical positive psychological framework to propose a domain-based systems model of positive change called the Synergistic Change Model. This model proposes that enduring positive change depends on the formation of mutually supportive interactions across multiple domains of psychological and social functioning. The paper uses the model to explore three types of response to intervention – relapse, spill-over, and synergy – which have been supported in the existing positive psychology literature. Three practical intervention strategies arising from the model are outlined to inform the design of future positive interventions. The model challenges reductionistic approaches to positive change and offers several approaches to embrace the complexities of lasting positive change in future theory and research.     

The Equity-Control Model as a Predictor of Vandalism Among College Students1

The equity-control model of vandalism (Baron & Fisher, 1984; Fisher & Baron, 1982) is used to conceptualize vandalism among college students. The model predicts that vandalism is most likely where there are low perceived equity (perceived lack of fairness in one's social or environmental arrangements) and low to moderate perceived control (perceived inability to effectively modify outcomes and arrangements). To test the model, university students were given questionnaires which measured perceived equity and control as these factors relate to the university and to dormitory living. Using multiple regression analysis, the interaction of equity and control was predictive of vandalism: Subjects with low perceived equity and control were most likely to report they engaged in vandalistic acts.
