Marital Status and Outcome in Patients with Coronary Heart Disease

The purpose of this study was to examine the relationship of marital status to health outcomes in 818 post-MI, coronary artery bypass surgery, and angioplasty patients (651 males, 157 females) from seven Northern California hospitals who completed 12 months of a nurse-managed, home-based multifactorial risk reduction program. Compared to married patients, nonmarried patients were significantly less likely to complete the program than married patients, more likely to smoke at baseline, and drank significantly less alcohol at baseline. At 12 months there were no significant differences between married and nonmarried groups on smoking cessation rates, HDL, LDL, triglycerides, or exercise treadmill test results. When patients were categorized as married, divorced, separated, widowed, or single, similar results were found for the analyses using two groups (married versus nonmarried), with the following exceptions. Separated patients were significantly less likely to quit smoking. In addition, separated patients showed significantly higher rates of starting (and continuing) to smoke during the time following their MI. Mortality was not significantly different between married and unmarried patients. Implications for intervention with separated patients and the importance of assessing both marital status and marital quality are discussed.     

On the relationship between category intensions and extensions in children

We contrasted four theories of natural language category acquisition by investigating the relation between category intensions and extensions in children (kindergarteners, second graders, fifth graders) and in college students. Everyone was asked to define a category term, to make category membership judgments of possible exemplars, and to judge whether the possible exemplars possessed features generated by them and by previous adult subjects. Adult judges were also asked to judge whether the possible exemplars possessed the features generated by the subjects. Children's intensions and extensions were very consistent. In addition, children's extensions were reliably smaller than adults', and the features which children generated were more specific than those generated by adults. None of the existing theories discussed can explain this pattern of results. An exemplar-based model is proposed to do so.     

The Relationship Between Nonsuicidal Self‐Injury and Suicidal Ideation

This correlational study was conducted with 403 undergraduate college students from 2 universities. The authors used path analysis and bootstrap regression to analyze the relationships between variables. Locus of control and family connectedness related to current nonsuicidal self‐injury (NSSI) engagement. However, when entered into the same regression, the variables current NSSI engagement and current NSSI number of methods used mediated all other relationships with suicidal ideation. Implications to current theories and clinical practice are provided.     

Bayesian theories of conditioning in a changing world

The recent flowering of Bayesian approaches invites the re-examination of classic issues in behavior, even in areas as venerable as Pavlovian conditioning. A statistical account can offer a new, principled interpretation of behavior, and previous experiments and theories can inform many unexplored aspects of the Bayesian enterprise. Here we consider one such issue: the finding that surprising events provoke animals to learn faster. We suggest that, in a statistical account of conditioning, surprise signals change and therefore uncertainty and the need for new learning. We discuss inference in a world that changes and show how experimental results involving surprise can be interpreted from this perspective, and also how, thus understood, these phenomena help constrain statistical theories of animal and human learning.     

The “Big Tent” of Community Psychology: Reactions to Paul Toro’s 2004 Presidential Address

This article summarizes discussions that took place following Paul Toros presidential address for the Society for Community Research and Action (SCRA). Toro argued that community psychology and SCRA are big tents. He suggested growth through increasing the involvement of ethnic minorities, community practitioners, international colleagues, students and early career professionals and individuals from allied disciplines. Themes in the discussions included: the founding values of community psychology, diversity, and social action. Those present felt that the field was facing a mid-life crisis and needed to re-establish its identity. Newer professionals looked to their seasoned colleagues to help define and establish that identity, and involve them in the process. Respondents were supportive of increased involvement of individuals from oppressed groups and practitioners in SCRA. Less attention was paid to increasing the role of international colleagues, professionals from allied disciplines, and members of the community.
