A Model of Contagion Through Competition in the Aggressive Behaviors of Elementary School Students

This article extends the work of Kellam, Ling, Merisca, Brown and Ialongo (1998) by applying a mathematical model of competition between children to peer contagion in the aggressive behaviors of elementary school students. Nonlinearity in the relationship between group aggression and individual aggression at 2-year follow-up is present. Consistent with the findings of Kellam et al. (1998), hierarchical linear modeling indicates that the relationship is statistically significant for those students whose initial parental ratings of aggressive behavior were above the sample median. In the context of competition between students, the behavior of initially aggressive students may be negatively reinforced. Lowering aggression in the school environment may therefore be the most effective way to lower the level of these students aggressive behavior.     

Families and Schools Together: an experimental analysis of a parent-mediated multi-family group program for American Indian children

The goals of this randomized intervention study were to: (a) increase academic performance among American Indian children ages 4-9 years and (b) reduce classroom problem behaviors. To achieve these goals, the multi-family group program called Families and Schools Together (FAST) was adapted with three American Indian Nations in Wisconsin. Over 3 years, seven multi-family group cycles of FAST were implemented, each lasting 8 weeks. In collaboration with the College of Menominee Nation, this parent intervention approach was adapted to express tribal values while maintaining its core components. Fifty pairs of universally recruited American Indian students at three schools who were assessed, matched on five variables, and then randomly assigned to either the FAST or non-FAST control condition. Pretest, posttest, and 9- to 12-month follow-up data were collected by American Indian staff and university students on multiple indicators of academic and behavioral performance. Of the 50 families that attended FAST meetings at least once, 40 graduated (80%) from the 7 FAST cycles. On the immediate posttest, statistically significant differences in improvement, favoring FAST participants were found on the Aggressive Behavior scale of the teacher-rated Child Behavior Checklist (CBCL) and on the parent-rated Withdrawn scale of the same instrument. On the 1-year follow-up assessment, parent CBCL ratings indicated that FAST students had maintained their less withdrawn status and teacher ratings on the Social Skills Rating Scale (SSRS) revealed that FAST participants had exhibited relatively greater improvement in their academic competence. Parent surveys of the graduated students generally showed satisfaction with the program. Implications of the present results and future research directions are discussed.     

Poverty Among Adults with Disabilities: Barriers to Promoting Asset Accumulation in Individual Development Accounts

Adults with disabilities disproportionally experience poverty. We examine one novel strategy to promote economic well-being among adults with disabilities living in or near poverty, namely Individual Development Accounts (IDAs). IDAs are designed to help individuals save money and subsequently accumulate assets. Although adults with disabilities account for the majority of IDA participants, scant attention has been paid to their IDA saving performance. We describe the significance of accumulating assets, particularly as it relates to adults with disabilities. We then map the nature of IDA programs and analyze barriers to participation in IDAs and asset accumulation related to conflicting federal policies and a lack of sensitivity to disability-specific needs. We conclude by offering policy recommendations from our analysis, including the need to eliminate the means-tests used in welfare policies, de-linking participation in IDAs from employment status, and involving people with disabilities in designing and evaluating asset accumulation policies and programs.     

Multiracial Identity,Color‐Blind Racial Ideology,and Discrimination: Professional Counseling Implications

Because of the expansive multiracial population growth in the United States, the authors explored multiracial identity integration (MII), color‐blind racial ideology (CBRI), and discrimination using regression analyses with 288 individuals. CBRI and discrimination significantly correlated and predicted MII, with 15.3% of the variance explained by discrimination and CBRI. Moderation analysis revealed that CBRI did not moderate the relationship between discrimination and MII. Continued research among multiracial individuals is recommended to better understand the CBRI and racial identity link.     

Uncertainty-dependent activity within the ventral striatum predicts task-related changes in response strategy

Recent neuroimaging work has demonstrated that the ventral striatum (VS) encodes confidence in perceptual decisions. However, it remains unclear whether perceptual uncertainty can signal the need to adapt behavior (such as by responding more cautiously) and whether such behavioral changes are related to uncertainty-dependent activity within the VS. Changes in response strategy have previously been observed following errors and are associated with both medial frontal cortex (MFC) and VS, two components of the performance-monitoring network. If uncertainty can elicit changes in response strategy (slowing), then one might hypothesize that these changes rely on the performance-monitoring network. In the present study, we investigated the link between perceptual uncertainty and task-related behavioral adaptations (response slowing and accuracy increases), as well as how such behavioral changes relate to uncertainty-dependent activity within MFC and VS. Our participants performed a two-choice perceptual decision-making task in which perceptual uncertainty was reported on each trial while behavioral and event-related functional magnetic resonance imaging data were collected. Analysis of the behavioral data revealed that uncertain (but correct) responses led to slowing on subsequent trials, a phenomenon that was positively correlated with increased accuracy. Critically, post-uncertainty slowing was negatively correlated with the VS activity elicited by uncertain responses. In agreement with previous reports, increases in MFC activation were observed for uncertain responses, although MFC activity was not correlated with post-uncertainty slowing. These results suggest that perceptual uncertainty can serve as a signal to adapt one’s response strategy and that such behavioral changes are closely tied to the VS, a key node in the performance-monitoring network.     

Motivation to Pursue Genetic Testing in Individuals with a Personal or Family History of Cardiac Events or Sudden Cardiac Death

Genetic testing is becoming increasingly available for cardiac channelopathies, such as long QT syndrome and Brugada syndrome, which can lead to sudden cardiac death. Test results can be used to shape an individual’s medical management and to identify at-risk family members. In our qualitative study, all participants had a personal or family history of a diagnosed cardiac arrhythmia syndrome or sudden cardiac death. Open-ended interviews were conducted individually and in focus groups. Interviews were audio recorded, transcribed verbatim, and analyzed using a qualitative grounded-theory approach. Of 50 participants, 37 described their motivations for pursuing genetic testing for long QT syndrome or another cardiac channelopathy. Participants’ motivations included: to find an explanation for a family member’s sudden death, to relieve uncertainty regarding a diagnosis, to guide future medical management, to allay concern about children or other family members, and to comply with recommendations of physicians or family members. Perceived reasons not to pursue genetic testing included denial, fear, and lack of information. The genetic counseling and informed consent process can be enhanced by understanding and addressing an individual’s internal and external motivations either for or against pursuing genetic testing.
