The effects of statistical training on choice heuristics in choice under uncertainty

Kahneman and Tversky (1984) proposed that decision makers perceive choice uncertainty in two ways: (1) as a distribution of possible outcomes or (2) as a single uncertain outcome. Using statistical training as a factor that influences these perceptions, and thus the type of decision approach individuals use, we found that individuals with different levels of experience displayed differences in the decisions they made and in the choice heuristics used to make those decisions. Statistically naive individuals were more likely to prefer loss-minimizing alternatives, use a more non-compensatory heuristic, and spend more time on loss-related information than their statistically experienced counterparts. When a distributional cue, indicating the distributional nature of choice outcomes, was presented to both experience groups, the naive group was found to use a decision approach similar to the experienced group and to make similar decisions. The results are discussed in terms of the need to include factors that alter individuals' approaches to uncertainty in future behavioral models of uncertain choice.     

“Why My Child?”: Parental Attributions for Children's Special Needs1

Although research exists on how attributions for traumatic life events are related to adjustment, little has focused on parents’ attributions for their children's special needs. Parents were interviewed twice over 1 year about their attributions for their children's special needs. We used parents’ open-ended responses during the initial interview to construct a ratings survey for the second interview. Parents of children with Down's syndrome made attributions to genetic fluke, age, and fate/God's will; parents of autistic children made attributions to heredity and environment; parents of developmentally delayed children made attributions to medical problems and stress during pregnancy. Self-blame attributions and attributions to the environment were related to worse adjustment, whereas attributions to fate/God's will were related to better adjustment. Implications for family interventions and physicians are discussed.     

Group support interventions for women with breast cancer: who benefits from what?

Research on the benefits of social support groups has been inconclusive. One reason is that individual differences in intervention responses have rarely been examined. The authors determined the extent to which individual difference variables moderated the effects of an information-based educational group and an emotion-focused peer discussion group on the mental and physical functioning of women with breast cancer (n = 230). The authors administered the SF-36 (S.E. Ware, K.K. Snow, M. Kosinski, & B. Gandek, 1993), a multidimensional quality of life instrument, pre- and postintervention. Educational groups showed greater benefits on the physical functioning of women who started the study with more difficulties compared with less difficulties (e.g., lacked support or fewer personal resources). Peer discussion groups were helpful for women who lacked support from their partners or physicians but harmful for women who had high levels of support. Implications of these results for clinical interventions are discussed.     

Two Important Distinctions in Social Support: Kind of Support and Perceived Versus Received1

The present study was conducted to examine the effects of social support on adjustment to a first cardiac event. There were two goals: (a) to determine which function of support best facilitated adjustment and (b) to determine whether perceived or received support had a greater impact on psychological health. Sixty-four patients and their spouses were interviewed shortly before hospital discharge and 3 months following discharge. The results indicated that perceived support has a greater impact on adjustment than received support and that received support does not necessarily indicate that needs are being met. The most helpful form of support was best understood by considering the stressor phase, patient and spouse needs, and the adjustment outcome. Consistent with previous research, however, the negative aspects of social relationships were more robust predictors of well-being than the positive aspects of social relationships.     

Judgments of men's and women's feelings during hypothetical social interactions

We studied college students' perceptions of how good/bad and how powerful/powerless men and women feel during hypothetical social interactions. Stimuli were constructed by combining each of 16 behaviors that fell into four categories (negative, low power, sexual, and help) with each of four dyads (male-male, male-female, female-male, female-female). Subjects made judgments about the likelihood of each behavior occurring, and about how actors and recipients felt when engaging in each of 16 behaviors. Three themes pervaded the results. First, subjects perceived men to feel more powerful than women whether behaving as actors or recipients—especially during interactions with women. Second, subjects perceived behaviors to be more likely, and actors and recipients to feel better and more powerful when the interaction pattern was consistent with gender role norms. Third, subjects perceived recipients' affective responses as being more polarized in opposite-sex than in same-sex dyads. Results from this research show that subjects' perceptions about feelings are largely consistent with the literature on social interaction and sex role stereotypes, and are similar for male and female subjects. In addition, our results provide a rich set of hypotheses concerning whether perceptions of feelings reflect actual feelings and are related to interaction participants' actual behavior.

Agentic and communal traits and health: adolescents with and without diabetes

The authors examined whether agentic and communal traits are associated with relationship and health outcomes among adolescents with and without diabetes. They interviewed 263 teens (average age 12; 132 Type 1 diabetes; 131 healthy) on an annual basis for 5 years. The authors measured agency, communion, unmitigated agency, and unmitigated communion as well as parent and peer relationship quality, psychological distress, and diabetes health. In concurrent and lagged multilevel models, unmitigated communion and unmitigated agency were associated with poor relationship outcomes and greater psychological distress for those with and without diabetes. In lagged analyses, unmitigated communion predicted deterioration in diabetes health. Communion and agency were associated with positive relationship and health outcomes, with the former being stronger than the latter. These results underscore the need to focus on unmitigated agency and unmitigated communion when studying the implications of personality for health during adolescence.     

Implications of Psychosocial Factors for Diabetes Outcomes among Children with Type 1 Diabetes: A Review

We adopt a risk and resistance framework to review the literature on the psychosocial factors that influence diabetes outcomes—specifically self‐care behavior (blood glucose monitoring, diet, exercise, insulin administration) and glycemic control. We examine both personal and social/environmental risk and resistance factors. We conclude by suggesting conceptual and methodological directions for future research. Conceptually, we suggest that researchers examine the synergy among variables that cut across domains, mechanisms linking psychosocial factors to diabetes outcomes, and the impact of goals on health. Methodologically, we suggest that researchers examine age, gender, and race as moderator variables; utilize momentary data collection technology; and employ more sophisticated longitudinal analyses.     

The role of masculinity in a prognostic predictor of heart attack severity

Coronary heart disease (CHD) is the leading cause of mortality and morbidity in the United States for both men and women. Men, however, are more likely that women to suffer from CHD at all ages. While previous research has linked Type A behavior to CHD, investigators have failed to note the role traditional masculinity plays in the development of that behavior pattern and in the development of other psychosocial risk factors for CHD. In the present study, 90 postmyocardial infarction patients were interviewed shortly before hospital discharge. The masculinity-CHD relationship was hypothesized to be mediated by masculinity's link to Type A behavior, poor health practices, and impaired social networks. Masculinity, along with these mediating variables, was then expected to be related to the Peel prognostic indicator of heart attack severity. Results indicated that negative or extreme masculinity was related to each of the mediating variables and to heart attack severity, but the effect of masculinity on heart attack severity was not mediated by Type A behavior, poor health practices, or impaired social networks.     

Psychological and physical adjustment to breast cancer over 4 years: identifying distinct trajectories of change.

The goal of this study was to identify distinct trajectories of adjustment to breast cancer over 4 years as well as to distinguish among the different trajectories. The mental and physical functioning of 287 women with breast cancer who remained alive and disease free through 4 years of follow-up were examined. The majority of women showed slight and steady improvement in functioning with time, but subgroups of women were identified who showed marked improvement and marked deteriorations over time. Age successfully distinguished different trajectories of physical functioning. Indices of personal resources (i.e., self-image, optimism, perceived control) and social resources (i.e., social support) successfully distinguished different courses of mental and physical functioning.
