Stress Among African American Emerging Adults: The Role of Family and Cultural Factors

The aim of this study was to examine the effects of family and cultural variables on stress among African American emerging adults. Data from this study was collected as part of a larger study that examined cultural, family, and contextual factors and smoking among African American youth in 5th, 8th, and 12th grades. Data were collected from high school seniors at the end of their 12th grade year and 6 months post high school. Multiple regression analyses were conducted to determine whether racial identity, family cohesion, and parental monitoring influence students’ perceived frequency of stress. Higher levels of racial identity were associated with more perceived stress. There were no significant main effects for either parental monitoring or family cohesion on stress. There were significant interactions between racial identity and parental monitoring and between parental monitoring and family cohesion. Study implications are discussed regarding the importance of stress reduction programs for African American emerging adults and for parents of these adults.     

Posterror slowing predicts rule-based but not information-integration category learning

We examined whether error monitoring, operationalized as the degree to which individuals slow down after committing an error (i.e., posterror slowing), is differentially important in the learning of rule-based versus information-integration category structures. Rule-based categories are most efficiently solved through the application of an explicit verbal strategy (e.g., “sort by color”). In contrast, information-integration categories are believed to be learned in a trial-by-trial, associative manner. Our results indicated that posterror slowing predicts enhanced rule-based but not information-integration category learning. Implications for multiple category-learning systems are discussed.     

Combating intimate partner violence in Africa: Opportunities and challenges in five African countries

Recent research results emerging from Africa show a worrying situation regarding the levels of intimate partner violence (IPV) in various countries in the continent — levels that are quite high and place great financial burden on individuals and governments. This paper explores the magnitude, nature, and risk factors of IPV in five African countries, namely, Morocco, Nigeria, Namibia, Uganda, and Tanzania. The focus of the paper is to explore issues of IPV in these countries by considering the opportunities in each country that could assist in the prevention of violence, and also to identify inherent challenges that may pose threats to efforts in reducing the high IPV prevalence. As there are only limited studies on IPV in developing countries, new insights provided by this paper would afford relevant stakeholders a better understanding of the issue.     

Belief about immutability of moral character and punitiveness toward criminal offenders

The present research examined the association between belief about immutability of moral character and punitiveness toward criminal offenders. Overall, participants who believed that moral character is immutable (entity theorists) were more punitive than those who believed that it is changeable (incremental theorists). More important, the present research identified two mediational paths: Entity theorists made more internal attribution of criminal behavior and held stronger expectation of offenders' recidivism, both of which in turn led to stronger punitiveness. Also, contrary to some researchers' speculation, entity theorists did not perceive less controllability in criminal behavior. Implications for implicit theory research and criminal justice research are discussed.     

Differentiating Psychotic Patients From Nonpsychotic Patients With the MMPI–2 and Rorschach

Rorschach responses of 36 process and 23 reactive schizophrenics have been evaluated for presence of primary and secondary process thinking, and for oral, anal, sex, aggression, and anxiety content. Responses of the process schizophrenics involved more primary process than secondary process thought, whereas the reactive schizophrenics' responses showed more secondary than primary process thinking. A linear trend, parallel for both groups, was noted with regard to frequency of content responses, such that anxiety was greater than aggression, which was greater than oral, which was greater than sex and in turn was greater than anal. In both groups oral content was least invaded by primary process thinking, the remaining categories tended to cluster.     

Comparing the Effects of Three Cognitive Tasks on Indicators of Mental Fatigue

Abstract

This investigation assessed the impact of three cognitively demanding tasks on cognitive performance, subjective, and physiological indicators of mental fatigue. Following familiarization, participants completed four testing sessions, separated by 48?h. During each session, participants watched a 45-min emotionally neutral documentary (control) or completed one of the following computer tasks: Psychomotor Vigilance Task (PVT); AX-Continuous Performance Test (AX-CPT); or Stroop Task. Mental fatigue was assessed before and at regular periods for 60?min following the 45-min treatments. Cognitive performance was assessed using 3-min PVT, and task performance. Subjective assessments were conducted using the Brunel Mood Scale, and visual analog scales (VAS). Physiological indicators of mental fatigue included electroencephalography (EEG), and heart rate variability (HRV). Subjective ratings of mental fatigue increased from pre to 0-min post in all-treatments, but not the documentary (p?p?相似文献   

Comparing the Self-Concepts of Persons With and Without Physical Disabilities

Tam and Watkins (1995b) explored the basis of self-concepts of physically disabled and nondisabled Hong Kong Chinese adults and developed the hierarchical multidimensional self-concept models. Two questionnaires that measure self-concept were developed and validated for those groups. The questionnaires share 41 common items in 6 self-concept areas. In the present study, the 2 groups' responses were compared via univariate analysis of variance. The nondisabled participants (n % 200) were found to have statistically significantly higher means than their disabled counterparts (n % 214) in total self-concept, material self-concepts, and physical self-concepts. There were no significant differences in their family, social, and work self-concepts. The nondisabled participants reported greater openness (indicated by higher self-criticism scores).     

Response Inhibition and ADHD Traits: Correlates and Heritability in a Community Sample

Endophenotypes or intermediate phenotypes are of great interest in neuropsychiatric genetics because of their potential for facilitating gene discovery. We evaluated response inhibition, latency and variability measures derived from the stop task as endophenotypes of ADHD by testing whether they were related to ADHD traits in the general population, heritable and shared genetic risk with ADHD traits. Participants were 16,099 children and adolescents, ages 6 to 18 years who visited a local science center. We measured ADHD traits using the Strengths and Weaknesses of ADHD-symptoms and Normal-Behavior (SWAN) rating scale and performance on the stop signal task (SST)—response inhibition (SSRT), response latency (GoRT), and response variability (GoRTSD). Regression analysis was used to assess the relationship of cognitive measures and ADHD traits while controlling for family, age, sex, ethnicity, socioeconomic status and treatment status. Heritability of ADHD and cognitive traits was estimated using SOLAR in 7,483 siblings from 3,507 families that included multiple siblings. Bivariate relationships between pairs of variables were examined. Individuals with greater ADHD trait scores had worse response inhibition, slower response latency, and greater variability. Younger participants and girls had inferior performance although the gender effects were minimal and evident in youngest participants. Inhibition, latency, variability, total ADHD traits, inattention and hyperactivity-impulsivity scores were significantly heritable. ADHD traits and inhibition, but not latency or variability were coheritable. In the largest study in the general population, we found support for the validity of response inhibition as an endophenotype of ADHD.
