Neurobiological and memory models of risky decision making in adolescents versus young adults

Predictions of fuzzy-trace theory and neurobiological approaches are examined regarding risk taking in a classic decision-making task--the framing task--as well as in the context of real-life risk taking. We report the 1st study of framing effects in adolescents versus adults, varying risk and reward, and relate choices to individual differences, sexual behavior, and behavioral intentions. As predicted by fuzzy-trace theory, adolescents modulated risk taking according to risk and reward. Adults showed standard framing, reflecting greater emphasis on gist-based (qualitative) reasoning, but adolescents displayed reverse framing when potential gains for risk taking were high, reflecting greater emphasis on verbatim-based (quantitative) reasoning. Reverse framing signals a different way of thinking compared with standard framing (reverse framing also differs from simply choosing the risky option). Measures of verbatim- and gist-based reasoning about risk, sensation seeking, behavioral activation, and inhibition were used to extract dimensions of risk proneness: Sensation seeking increased and then decreased, whereas inhibition increased from early adolescence to young adulthood, predicted by neurobiological theories. Two additional dimensions, verbatim- and gist-based reasoning about risk, loaded separately and predicted unique variance in risk taking. Importantly, framing responses predicted real-life risk taking. Reasoning was the most consistent predictor of real-life risk taking: (a) Intentions to have sex, sexual behavior, and number of partners decreased when gist-based reasoning was triggered by retrieval cues in questions about perceived risk, whereas (b) intentions to have sex and number of partners increased when verbatim-based reasoning was triggered by different retrieval cues in questions about perceived risk.     

Implicit Coping Responses to Racism Predict African Americans' Level of Psychological Distress

African Americans report experiencing discrimination on a frequent basis, and these experiences have been linked to psychological distress. Coping responses to racism have been suggested to mediate the relationship between discrimination and distress. This study introduces the first measure of African Americans' implicit emotional and coping responses to racism and examines the measure's ability to predict psychological distress. The Go/No-Go Association Task (Nosek &; Banaji, 2001 Nosek , B. A. , &; Banaji , M R. ( 2001 ). The go/no-go association task . Social Cognition , 19 , 625 – 664 .[Crossref], [Web of Science ®] , [Google Scholar]) was adapted to assess African Americans' implicit association of racial prejudice with each of four coping and two emotional responses. Anxiety and general psychological distress were assessed with the Brief Symptom Inventory. Greater implicit association between prejudice and “seeking support” was found to predict lower anxiety and general distress, demonstrating the potential utility of implicit measures in assessing coping responses to racism and their consequences.     

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.     

Psychosocial predictors of natural killer cell mobilization during marital conflict.

This study examined how specific emotions relate to autonomic nervous and immune system parameters and whether cynical hostility moderates this relationship. Forty-one married couples participated in a 15-min discussion about a marital problem. Observers recorded spouses' emotional expressions during the discussion, and cardiovascular, neuroendocrine, and immunologic parameters were assessed throughout the laboratory session. Among men high in cynical hostility, anger displayed during the conflict was associated with greater elevations in systolic and diastolic blood pressure, cortisol, and increases in natural killer cell numbers and cytotoxicity. Among men low in cynical hostility, anger was associated with smaller increases in heart rate and natural killer cell cytotoxicity. These findings suggest that models describing the impact of stress on physiology should be refined to reflect the joint contribution of situational and dispositional variables.     

Children of Incarcerated Mothers

We review the literature on children whose mothers are incarcerated in jails or prisons. These children typically experience a great many risk factors besides their mothers' incarceration, including poverty, drug and alcohol problems in their families, community violence, and multiple changes in caregivers. Children's lives are greatly disrupted when mothers are arrested, and most children show emotional and behavioral problems. The impact this has depends on the age of the child, the alternate caregiving arrangements, and the course of the mother's incarceration. Children of incarcerated mothers experience internalizing (fear, withdrawal, depression, emotional disturbance) and externalizing (anger, fighting, stealing, substance abuse) problems, as well as heightened rates of school failure and eventual criminal activity and incarceration. Research in this area is scarce and often of poor quality. A research agenda which is guided by a transactional, ecological, and developmental model, and which examines children's well-being over the course of the mothers' incarceration is suggested.     

Direct-to-Consumer Genetic Testing: Introduction to the Special Issue

This issue of the Journal of Genetic Counseling is devoted to direct-to-consumer (DTC) genetic testing. The 15 articles in this special issue address practice considerations for genetic counselors and other health care professionals; the benefits and limitations of DTC genetic testing; consumer and provider attitudes towards and experience with DTC testing; and the roles and educational needs of genetic counselors and other health care providers in providing and interpreting DTC genetic testing. In this introduction to the special issue, we provide a brief background on DTC genetic testing, summarize the important contribution of the articles included in this issue, and outline the essential work that still needs to be done as genetic counselors are increasingly engaged in discussions, education, and research about DTC genetic testing.     

Intuition's Powers and Perils

One of the biggest revelations of recent psychological science is the two-track human mind, which features not only a deliberate, self-aware “high road” but also a vast, automatic, intuitive “low road.” Through experience, we learn associations that provide fast and frugal intuitions that enable instantaneous social judgments and the pattern recognition that marks acquired expertise. But as studies of implicit prejudice and intuitive fears illustrate, unchecked gut feelings can also lead us astray. Intuition's powers and perils appear in various realms, from sports to business to clinical and interviewer judgments.     

A psychological predictor of elders' driving performance: social‐comparisons on the road

Older individuals often believe they can drive better than their contemporaries. This belief is an example of downward social‐comparisons; they can be self‐enhancing tools that lead to beneficial outcomes. As predicted, we found that drivers who engaged in downward social‐comparisons were significantly less likely to have adverse driving events over time, after controlling for relevant factors (p = .02). This effect was particularly strong among women, who tend to experience more negative driving stereotypes (p = .01). The study was based on 897 interviews of 117 elder drivers, aged 70–89 years, over 2 years. Our findings suggest that interventions to reduce adverse driving events among elders could benefit from including a psychological component.     

Juvenile homosexual homicide

Limited information exists on juvenile homosexual homicide (JHH), that is, youths who perpetrate sexual homicides against same-sex victims. Only a handful of cases from the United States and internationally have been described in the literature. This study, the first of its kind, examines the epidemiology, victimology, victim-offender relationship, and weapon-use patterns in JHH offenders using a large U.S. database on homicide spanning three decades. The data for this study were derived from the Federal Bureau of Investigation's Supplementary Homicide Reports (SHRs) for the years 1976 through 2005. A total of 93 cases of JHH were identified. On average, three of these crimes occurred annually in the U.S., and there was a marked decline in its incidence over the study period. Ninety-five percent were male offender-male victim cases and 5% were female offender-female victim cases. JHH offenders were over-represented amongst all juvenile sexual murderers, similar to their adult counterparts. The majority of these boys were aged 16 or 17 and killed adult victims. They were significantly more likely to kill adult victims than other age groups, to be friends or acquaintances of the victims, and to use contact/edged weapons or firearms. Most offenders killed same-race victims, although Black offenders were significantly more likely than White offenders to kill interracially. A case report is provided to illustrate JHH. Further research is needed to promote our understanding of the pathogenesis, etiology, and associated risk factors for this aberrant form of murder by children.
