The dilution effect: judgmental bias,conversational convention,or a bit of both?

This study explored competing normative interpretations of the dilution effect: the tendency for people to underutilize diagnostic evidence in prediction tasks when that evidence is accompanied by irrelevant information. From the normative vantage point of the intuitive statistician, the dilution effect is a judgmental bias that arises from the representativeness heuristic (similarity-matching of causes and effects). From the normative prospective of the intuitive politician, however, the dilution effect is a rational response to evidence presented in a setting in which Gricean norms of conversation are assumed to hold. The current experiment factorially manipulated conversational norms, the degree to which diagnostic evidence was diluted by irrelevant evidence, and the accountability of subjects for their judgments. Accountable subjects demonstrated a robust dilution effect when conversational norms were explicitly primed as well as in the no-priming control condition, but no dilution when conversational norms were explicitly deactivated. Non-accountable subjects demonstrated the dilution effect across norm activation conditions, with the strongest effect under the activation of conversational norms. Although the results generally support the conversational-norm interpretation of dilution, the significant dilution effect among non-accountable subjects in the norm-deactivated condition is more consistent with the judgmental-bias interpretation.     

Outcome Expectancies and Expectancy Accessibility in Exercise Behavior

Most people do not engage in recommended levels of physical activity. Social cognition research indicates that self‐reported outcome expectancies (OEs) are associated with exercise behavior, but self‐report assessments have limitations. We investigated whether reaction times (RTs) to endorse outcome expectancies would capture unique information about spontaneous cognitive processes associated with exercise behavior. Exercisers and sedentary participants were randomly assigned to complete an exercise test or to rest. Participants completed an OE questionnaire and RT task before and after the test/rest. On the RT task, exercisers endorsed exercise positive outcomes more rapidly than sedentary participants. Furthermore, reported OEs and RTs were independently associated with exercise status. RTs may afford a more comprehensive assessment of the cognitive processes associated with exercise behavior.     

Multiple Perspectives of Parent-Adolescent Sexuality Communication: Phenomenological Description of a Rashoman Effect∗

Due to methodological limitations, past meta-analytic research was not able to identify which treatment was most effective for specific marital distress levels. By converting pre-and post-test scores from marital research into equivalent Dyadic Adjustment Scale scores, it was possible to isolate mild, moderate, and severe levels of marital distress. Results show that Emotionally Focused Therapy is significantly more effective than isolated Behavioral Marital Therapy interventions for the treatment of moderate marital distress. Future directions of outcome research are also discussed.     

Communicating to Farmers About Skin Cancer The Behavior Adaptation Model

Although health campaigns promote avoidance of behaviors that put an individual's health at risk, often these behaviors cannot be avoided, and campaign messages designed to encourage behavior adaptation afford greater likelihood of success. With that in mind, a model of health risk behavior adaptation was proposed and tested using four different behaviors in a communication campaign aimed at reducing farmers' risk for skin cancer, farmers and farm wives answered a series of questions about their skin cancer prevention and detection behaviors and attitudes. Interpersonal expectancies, social resources, and actual procedural knowledge predicted perceived procedural knowledge and public commitment, which, in turn, predicted behavior adaptation.     

Not Simply “In Their Heads”: Individual Differences Associated With Victimization and Health1

Research has not examined whether victimization predicts health after controlling for personality differences associated with victimization and health. In Study 1, college students (N = 1182) completed surveys assessing victimization, health, and personality. In Study 2, college students (N = 69) participated in a short‐term longitudinal study that examined whether (a) victimization would predict health changes; (b) increases in victimization would lead to increased health problems; and (c) fall health would predict spring victimization when personality was considered. After controlling for individual differences, we found victimization predicted health outcomes (Study 1) and health problems over time (Study 2). These findings suggest the victimization–health link may occur because of physiological changes, rather than personality differences associated with victimization and health.     

Relational Individualism and Feminist Therapy

My aim here is to clarify the practice of honoring and validating the relational model of self which plays an important role in feminist therapy. This practice rests on a tangle of psychological claims, moral and political values, and mental health norms which require analysis. Also, severe pathology affects the relative “relationality” of the self. By understanding it we can better understand the senses of autonomy compatible with and even required for a desired relationality.     

Attachment styles and other predictors of relationship satisfaction in dating couples

A sample of 186 dating couples completed questionnaires in order to examine the relevance of attachment styles, romantic beliefs, self-esteem, and gender roles to relationship satisfaction. The aim was to assess whether male and female anxiety over abandonment and comfort with closeness, and interactions among them, predicted satisfaction beyond the contribution of the other variables. Using multiple-regression analysis, it was found that attachment styles successfully predicted satisfaction, after controlling for romantic beliers, self-esteem, and gender roles. Both partners were particularly dissatisfied when either partner suffered high anxiety over abandonment or low comfort with closeness. Implications for gender roles, relationship satisfaction, and attachment styles are discussed.     

Evaluating Therapist Competency and Adherence to Behavioral Family Management with Bipolar Patients

The present study assessed fidelity to the behavioral family management (BFM) model for treating bipolar disorder patients and their families. The BFM Therapist Competency/Adherence Scale (BFM-TCAS) was developed to evaluate clinicians' competency and adherence to BFM, as outlined by Miklowitz' (1989) BFM Manual for use with bipolar patients. Therapist competency and treatment adherence was also evaluated with regard to two family characteristics: overall level of family difficulty and family expressed emotion (EE) status. The BFM-TCAS was used to code 78 videotaped sessions of 26 families with a bipolar member, selected from a larger treatment study of bipolar disorder patients. The findings suggest that, overall, clinicians adhered closely to the BFM manual. Specific areas in which there was high competency and treatment adherence were (a) skill in conveying factual information about bipolar illness, (b) establishment of a therapeutic environment, and (c) ability to take command of therapy sessions. The one area in which there was less compotency and relatively weak adherence to the manual was the use of between-session homework assignments to assist families in mastering the BFM exercises. Results of this study also suggest that, for the most part, therapist competency and adherence ratings were not related to overall level of difficulty or to family EE status.     

Gender,Marital Status,and Alcohol Behavior: The Neglected Role of Religion

Substantial previous research indicates that married persons enjoy better mental and physical health than others. One prominent explanation for these patterns is that married persons practice better health behaviors, including lower levels of alcohol consumption, particularly heavy drinking. However, studies of marital status differences in health behaviors have ignored the role of religious homo/heterogamy and attendance, important potential confounding and moderating factors. Focusing on alcohol behavior, we analyze 1977–1994 General Social Survey data, finding that lower levels of drinking are especially pronounced among homogamous conservative couples, and to a lesser extent among mixed-faith unions with one conservative partner. Controlling for other background characteristics, nonconservatives married to nonconservatives do not consistently consume less alcohol than unmarried persons, suggesting that much of the apparent marital status effect on drinking is actually due to religious factors. Contrary to some prior theory and research, these patterns are broadly consistent for both men and women.
