Neuropsychologic Deficits in Children with Sickle Cell Disease and Cerebral Infarction: Role of Lesion Site and Volume

Little is known about the correlation between the location and size of cerebral infarction in children and neuropsychologic deficits. We related lesion location and volume on magnetic resonance exams to neuropsychologic performance in 28 children with cerebral infarcts due to sickle cell disease. Seventeen healthy siblings served as a comparison group. Children with anterior cerebral infarcts (n = 7) showed deficits in attention and executive skills, whereas children with more widespread cerebral infarcts (n = 18) showed additional deficits in spatial skills. The volume of cerebral infarction was associated with spatial and language performance, but minimally related to performance in other cognitive domains. The location and volume of cerebral infarction are both important for defining the type and magnitude of cognitive sequelae in childhood stroke.     

“Who I Am Depends on How Fairly I'm Treated”: Effects of Justice on Self‐Identity and Regulatory Focus

Across 2 experiments, we examined motivational processes elicited by justice‐related experiences. Specifically, we examined the effects of justice on recipients' self‐identity and regulatory focus. As predicted, those who experienced unfairness had a strong individual identity and prevention focus owing to the threats of social rejection and economic exploitation communicated by unfairness. Conversely, individuals exposed to fairness had strong interdependent identities and promotion focus owing to the favorable economic and socioemotional information communicated by fairness. These effects were accentuated among participants who reported high sensitivity to injustice and internal loci of control. Our findings are important because they highlight causal associations between justice and key motivation constructs.     

错误记忆研究范式评介

文章概括评介了当前错误记忆研究的几种主要范式及其各自可能的认知机制。联想研究范式(包括集中联想研究范式与类别联想研究范式)和无意识知觉范式描述了人们对单词的错误记忆,而误导信息干扰范式和KK研究范式则描述了人们对持续事件的错误记忆。这两类不同的研究范式证实了可能存在不同类型的错误记忆,且可能具有不同的认知加工机制。它们都从一定层面上揭示了错误记忆现象的本质和特征,并为人们进行更深入的研究提供了有效的方法。     

基于人脸记忆新任务的元认知监测准确性研究

元认知监测关注个体对自身认知活动的监控,是重要的高级认知过程。学习判断(judgments of learning)是元认知监测的一种重要形式。该研究同时采用人脸-姓氏记忆新任务与经典词对记忆任务,比较学习判断的准确性在两者中的差异。结果发现:人脸-姓氏记忆的学习判断准确性在相对准确性、绝对准确性和总体判断准确性上均显著高于词对记忆。结果表明:当任务本身的社会适应意义更强时,个体对认知水平的监测更加准确,提示元认知监测技能不仅受到个体自身学习和发展的影响,还可能与人类的长期进化过程有关。     

Intimate Partner Violence among West African Immigrants

Although the number of African immigrants arriving to the United States has increased significantly, there has been little investigation regarding their experiences of intimate partner violence or coping strategies. This study used focus groups and individual interviews to explore intimate partner violence among 32 heterosexual West African immigrants. Results suggest that although cultural expectations influence their coping strategies, West African–born men and women face different realities, with women reporting multiple instances of abuse and a sense of frustration with the existing options for assistance. Although participants discussed multilevel support structures within the immediate West African community to address intimate partner violence, all of these options maintained a gender hierarchy, leaving women dissatisfied. Challenges and barriers to partner violence resolution and coping strategies are identified. Results are examined in terms of their implications for addressing the needs of this underserved population. Implications for future research and services are discussed and highlighted.     

Interpersonal Violence,Depression, and Executive Function

This study considers links between the number of types of violence to which women have been exposed, depression, and executive functions (EFs). Substantial research has established EF deficits among depressed individuals as well as individuals exposed to trauma. Studies have also indicated a relationship between trauma exposure and depressive symptoms across a range of traumatic events, such as combat exposure, motor vehicle accidents, natural disasters, and assaults. This study examines this relationship in an ethnically diverse community sample of 93 women exposed to interpersonal violence who completed a battery of EF tasks that assessed processing speed, working memory, response inhibition, and set shifting. Women reported an average of 5.8 types of interpersonal violence events. The number of types of interpersonal violence events was significantly related to depressive symptoms, although not EF performance. Specific EFs, such as working memory and response inhibition, were positively related to depressive symptoms.     

Youth gang affiliation,violence, and criminal activities: A review of motivational,risk, and protective factors

Youth gangs are a universal phenomenon attracting increasing attention; the criminal and antisocial behavior perpetuated by youth gangs has an adverse impact on local communities across the globe. Although there is an extensive body of research that has examined the problems posed by youth gangs in America (and more recently in other countries), there have been relatively fewer empirical studies that examined the factors and psychological processes that are related to youth joining and leaving gangs. This review compiles the international research on the nature of youth gangs and critically evaluates: (a) the factors that motivate engagement in and desistance from gang-related activities, (b) risk and protective factors that impact on youths' propensity for gang membership, delinquency, and violent behavior, and the adverse consequences associated with gang affiliation, and (c) the relationship between gang-affiliation, youth violence, and criminal behavior.
