The Role of Familial Incarceration and Ethnic Identity in Suicidal Ideation and Suicide Attempt: Findings from a Longitudinal Study of Latinx Young Adults in California

Suicide is a leading cause of death among young adults; however, contextual risks and cultural factors are rarely studied in the context of ethnic minority suicidal ideation (SI) and suicidal attempt (SA). This study assessed the association between familial incarceration and suicide behaviors and examined ethnic identity as a potential moderator. Data from a longitudinal study of health among Hispanics (n = 1,094) in California were used to test associations between familial incarceration, ethnic identity, and SA and SI, adjusting for demographic factors and covariates. Approximately 18% and 8% of respondents reported SI and SA, respectively. Compared to no incarceration, or the incarceration of a relative, parental incarceration was associated with higher odds (AOR: 2.09, 95% CI: 1.23–3.34) of SI whereas higher affective ethnic identity reduced the odds (AOR: 0.52, 95% CI: 0.31–0.89) of SA. Ethnic identity moderated the association between parental incarceration and SI (AOR: 0.33, 95% CI: 0.13–0.79). Incarceration of a family member can set the stage for exclusion from critical institutions and can have long‐term consequences for adult mental health. Promoting a positive ethnic identity may be a promising prevention strategy that could bolster resilience among at‐risk, urban minority youth.     

Vestibular influence on auditory metrical interpretation

When we move to music we feel the beat, and this feeling can shape the sound we hear. Previous studies have shown that when people listen to a metrically ambiguous rhythm pattern, moving the body on a certain beat--adults, by actively bouncing themselves in synchrony with the experimenter, and babies, by being bounced passively in the experimenter's arms--can bias their auditory metrical representation so that they interpret the pattern in a corresponding metrical form [Phillips-Silver, J., & Trainor, L. J. (2005). Feeling the beat: Movement influences infant rhythm perception. Science, 308, 1430; Phillips-Silver, J., & Trainor, L. J. (2007). Hearing what the body feels: Auditory encoding of rhythmic movement. Cognition, 105, 533-546]. The present studies show that in adults, as well as in infants, metrical encoding of rhythm can be biased by passive motion. Furthermore, because movement of the head alone affected auditory encoding whereas movement of the legs alone did not, we propose that vestibular input may play a key role in the effect of movement on auditory rhythm processing. We discuss possible cortical and subcortical sites for the integration of auditory and vestibular inputs that may underlie the interaction between movement and auditory metrical rhythm perception.     

Large Costs, Small Benefits: Explaining Trade Dispute Outcomes

The United States frequently engages in negotiations with its trading partners over expanded market access for American firms. Although many of these negotiations involve markets worth millions or even billions of dollars, sometimes government officials bargain long and hard over issues that were never predicted to result in substantial benefits. For example, the United States held negotiations with Japan for more than 30 years over increased market access for American apples. These negotiations were ultimately carried to the highest levels of government, discussed at international conferences, and even ruled on by the World Trade Organization, yet estimates of the potential market for foreign apples never exceeded $15 million. Such protracted negotiations in this sector do not make sense from the perspective of expected utility theory but can be explained by prospect theory. Apple negotiations came to represent a spiral model for both the United States and Japan. As each side viewed its own losses as deepening over the course of negotiations, each became caught in a prospect theory spiral of actions and became willing to take even riskier actions in an attempt to recoup losses.     

Thoughts, Feelings and Intentions to Learn: Attitudes by Beginning Teachers Towards Aboriginal Peoples

Given that education plays a key role in the development of social attitudes, intentions to learn about other social groups is a strategic addition to cognitive and affective models of attitudes towards others. This project examined related yet discrete aspects of attitudes towards Australian Aboriginal peoples that are expressed by beginning teachers (N = 266). Cognitive aspects indicate positive and negative stereotyping of the social group. Affective aspects across situations relate positive feelings and negative feelings of guilt, worry and anger. Results suggest differential links from cognitive and affective aspects to intentions for positive and negative actions, and intentions to gain experience with others. The findings implicate broadly defined components of attitudes in situations where individuals have limited experience with people in other social groups.     

Jung's lives

Forty published life histories of C. G. Jung are grouped into eight categories: autobiography, hagiographies, pathographies, professional biographies, intellectual biographies, illustrated biographies, religious biographies, and joint Jung/Freud biographies. Each work is briefly reviewed in terms of its scope, its main contributions to the biographical literature on Jung, and its principal shortcomings. A short list of selected readings on Jung's life is recommended.     

Procrastination in College Students: The Role of Self-Efficacy and Anxiety

In this study, the authors examined the relationships among procrastination, efficacy expectations, anxiety, gender, and age for 141 university students. Participants were asked to think about a major project and to rate their efficacy regarding the skills needed to accomplish the project. Bivariate correlations showed that efficacy expectations and anxiety had significant, individual relationships with procrastination. When these variables were entered into a regression model, only cumulative efficacy strength was a significant predictor of procrastination. Implications for practice and research suggestions are discussed.     

Repetition and Reconfiguration: Demand‐Based Confabulation in Initial Eyewitness Memory

Repeated recall, as a result of repeated questioning, is typical of situations involving eyewitness evidence. The present study addressed questions of eyewitness performance with reference to repeated questioning in an initial interview, in a format based on actual police procedures. This experiment focused on eyewitness accuracy, eyewitness confidence, and the addition of false details to eyewitness accounts. Ninety‐two adult respondents were asked to recall all the information they could from a single viewing of a scene depicting an assailant aiming a handgun at a victim. This initial question was followed by three additional questions, in which respondents were asked to report any additional details they could recall. On average, respondents provided several times as many correct as false details to the initial question. However, performance deteriorated significantly to the three subsequent questions; on average, across the three subsequent questions, witnesses recalled nearly as much false as accurate information. Witness confidence was positively related to amount of accurate information recalled. However, confidence was also positively related to the number of instances of erroneous recall. These results indicate that reconfigurative dynamics begin to operate, producing confabulated responses in response to questioning demands, as early as the initial interview. This work may also help to clarify the critical relationship between accuracy and confidence in eyewitness reportage, at least within the framework reflected by the present research.

Aggression is suppressed by acute stress but induced by chronic stress: Immobilization effects on aggression, hormones, and cortical 5-HT1B/ striatal dopamine D2 receptor density

Although it has been established by a number of investigators that a variety of stressors are associated with the induction of aggressive behavior, two specific issues remain unanswered. First, it is unclear whether the contexts surrounding stressors (e.g., stressor length and chance of winning over opponents) change outcomes regarding aggressive behavior. Second, if a relationship exists between stress and aggressive behavior, altered levels of stress-related hormone (e.g., corticosterone [CORT]), as well as aggression-related biomarkers (e.g., testosterone [T], density of prefronto-cortical 5-HT(1B) receptor and striatal dopamine D(2) receptor [D2r]) may contribute to changes in aggressive behavior. Thus, we examined how immobilization (with a 1-, 5-, or 10-day exposure) would impact (1) a longitudinal course of aggression toward different-sized opponents, (2) levels of CORT and T, and (3) densities of 5-HT(1B) receptor (5-HT1Br) in the prefrontal cortex (PFC) and D2r in the striatum. It was found that, regardless of small or large opponents, a single 2-h exposure to immobilization reduced aggressive behavior (stress-suppressed aggression) over time, whereas repeated (10-day) exposure to immobilization escalated aggressive behavior (stress-induced aggression). These stress effects persisted up to 1 week of recovery from immobilization stress. Moreover, immobilized rats demonstrated elevated levels of T, but not CORT, as compared with controls. Finally, acute immobilization altered D2r densities in the shell of the nucleus accumbens, and chronic immobilization changed 5-HT1Br in the PFC, including the downregulation of 5-HT1Br densities in the right prelimbic and orbitolateral cortices. The potential relationships among stress, aggression, and 5-HT1Br/D2r roles are discussed.
