A daily diary investigation of Latino ethnic identity, discrimination, and depression

The objectives of the current study were to document the effects of discrimination on Latino mental health and to identify the circumstances by which ethnic identity serves a protective function. Instances of discrimination and depressive symptoms were measured every day for 13 days in a sample of Latino adults (N = 91). Multilevel random coefficient modeling showed a 1-day lagged effect in which increases in depression were observed the day following a discriminatory event. The findings also revealed differential effects of ethnic identity exploration and commitment. Whereas ethnic identity exploration was found to exacerbate the influence of daily discrimination on next-day depression, ethnic identity commitment operated as a stress buffer, influencing the intensity of and recovery from daily discrimination. The findings are discussed within a stress and coping perspective that identifies appropriate cultural resources for decreasing the psychological consequences associated with daily discrimination.     

Adjustment issues affecting employment for immigrants from the former soviet union

This article describes major issues, including culture shock and loss of status, that affect general adjustment of immigrants and refugees from the former Soviet Union who are resettling in the United States. Issues that affect career and employment adjustment are described and the interrelatedness of general and career issues is explored. Practical and positive suggestions for practitioners working with this population are offered.     

Unintentional Injury Risk in Children with Externalizing Behavior Disorders at Summer Camp

Children with externalizing behavior disorders such as attention-deficit/hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and conduct disorder (CD) have greatly increased risk of unintentional injury, but it is unclear what mechanisms are responsible for that increased risk. This study followed 22 children participating in a summer camp for children with ADHD. Injury incidents were recorded daily and a set of primary symptoms of behavioral disorders were recorded at 15-min intervals over the course of the 6-week summer camp experience (roughly 300 h of observing each child). We predicted symptoms of ODD and CD would be more strongly related to injury incidence than symptoms of ADHD. Results from univariate Poisson regression models confirmed our prediction. Symptoms of ODD and CD—violations and intentional aggression in particular—were related to injury incidence but symptoms of ADHD were not. This finding is consistent with a growing body of evidence that oppositional, noncompliant, and aggressive behavior patterns might be primarily responsible for increased risk for injury among children with externalizing behavior disorders. Thanks to Sylvie Mrug, Peter Winslett, and the other staff members of the STP camp for their cooperation.     

System-specific differences in behavior regulation: overrunning and underdrinking in molar nondepriving schedules

In two experiments we tested the molar regulation prediction that animals adjust schedule performance to reduce deviations from baseline response totals. Both experiments constrained the baseline drink-burst length under molar nondepriving schedules but allowed rats to continue running without drinking. In Experiment 1, rats were required to run in order to drink. In Experiment 2, water was delivered independently of running by fixed-time (FT) schedules. Under the run-to-drink contingency, rats exceeded their baseline amounts of running (overrunning) but failed to maintain their baseline water intake (underdrinking). The total amount of running that did not lead to drinking approximated baseline running. Under the FT schedules, rats again underdrank, but total running approximated baseline. These results do not support previous studies that have shown molar equilibrium effects under nondepriving reciprocal schedules. We conclude that (a) contingent running may not substitute for independent running; (b) intermittent access to water reduces the total instigation for drinking; (c) molar regulation differs under reciprocal and nonreciprocal schedules; and (d) more dynamic, system-specific regulatory models need to be developed.     

Predicting risk decisions in a modified Balloon Analogue Risk Task: Conventional and single-trial ERP analyses

Event-related potential (ERP) has the potential to reveal the temporal neurophysiological dynamics of risk decision-making, but this potential has not been fully explored in previous studies. When predicting risk decision with ERPs, most studies focus on between-trial analysis that reflects feedback learning, while within-trial analysis that could directly link option assessment with behavioral output has been largely ignored. Suitable task design is crucial for applying within-trial prediction. In this study, we used a modified version of the classic Balloon Analogue Risk Task (BART). In each trial of the task, participants made multiple rounds of decisions between a risky option (pump up the balloon) and a safe option (cash out). Behavioral results show that as the level of economic risk increased, participants were less willing to make a risky decision and also needed a longer response time to do so. In general, the ERP results showed distinct characteristics compared with previous findings based on between-trial prediction, particularly about the role of the P1 component. Specifically, both the P1 (amplitude and latency) and P3 (amplitude) components evoked by current outcomes predicted subsequent decisions. We suggest that these findings indicate the importance of selective attention (indexed by the P1) and motivational functions (indexed by the P3), which may help clarify the cognitive mechanism of risk decision-making. The theoretical significance of these findings is discussed.
