Increased difficulty with response inhibition occurs with age, although there is some controversy as to whether increased interference on Stroop tasks reflects difficulties with response inhibition or simply reflects generalized cognitive slowing. The Victoria Stroop Test (VST) is a brief, easily administered, psychometrically sound version of Stroop's original task. Performance on the VST by adults across a wide age span was examined to determine the association between age and various measures of interference. In addition, normative data for the VST were calculated. Participants were 272 healthy, community-dwelling adults age 18 to 94. Age and speed were negatively correlated on all trials of the VST. Importantly, however, interference scores that were corrected for baseline slowing remained highly correlated with age. Similarly, age and error scores on the interference trial were positively correlated, indicating decreased accuracy with age. These findings suggest that increased interference on Stroop tasks with age is not accounted for by simple cognitive slowing and more likely reflects other cognitive changes, such as decreased response inhibition. The VST has a number of administrative and psychometric strengths, and the provision of normative data should enhance its potential for clinical and research applications.  相似文献

Widespread dissemination of evidence-based programs for underserved populations may require non-traditional means of service provision. Collaboration with paraprofessionals from communities that are targeted for intervention holds promise as a delivery strategy that may make programs more accessible and acceptable, especially to parents living in low-income, urban neighborhoods. We describe a paraprofessional training program for individuals living in a community targeted for preventive intervention based on high levels of poverty and community violence. The design and implementation of the training program are described in the context of issues related to the use of paraprofessionals in community-based, preventive interventions with parents of young children. We also provide insight into lessons learned from a feasibility study as well as general guidelines for the development of paraprofessional training programs for delivery of evidence-based programs.  相似文献

We describe a university-community collaborative effort to tailor and deliver a prevention program for families of preschoolers living in low-income, urban communities. ParentCorps, which builds on efficacious interventions with parents and young children, aims to promote child social competence and prevent conduct problems by strengthening parenting skills, enhancing support for parents, and empowering parents to access resources in their communities. Active community engagement and collaboration were viewed as critical to the development of the program and its feasibility testing. We present an overview of community involvement in the development of ParentCorps and approaches taken to involve community members during a feasibility study. Areas of success and lessons learned are discussed.  相似文献

The aim of this study was to develop a Self-Talk Inventory for young adults. This inventory consisted of two scales. The Negative Self-Talk Scale included three categories of self-talk (depressive, anxious, and angry thoughts) and the Positive Self-Talk Scale, three categories (minimization, positive orientation, and coping self-instructions). Participants were 982 undergraduate students (Mean age = 20.35 years, SD = 2.16). They completed the self-talk scales together with the following scales to measure symptoms of affective disorders: the Center for Epidemiological Studies Depression Scale (CES-D), the State-Trait Anxiety Inventory (STAI), and the State-Trait Anger Expression Inventory (STAXI-T). Factor analyses confirmed the hypothesized structure for the Self-Talk Inventory. The relations between self-talk and symptoms of affective disorders (depression, anxiety, and anger) were also evaluated. In general, states-of-mind -SOM- ratios and negative cognitions showed a greater association with psychological symptoms than did positive cognitions. Results concerning the cognitive characteristics of depression, anxiety, and anger were mixed and partially supported the cognitive content specificity theory.  相似文献

The vast amount of biological information that is now available through the completion of the Human Genome Project presents opportunities and challenges. The genomic era has the potential to advance an understanding of human genetic variation and its role in human health and disease. A challenge for genomics research is to understand the relationships between genomics, race, and ethnicity and the implications of uncovering these relationships. Robust and scholarly discourse on the concept of race and ethnicity in genomic research should be expanded to include social and behavioral scientists. Interdisciplinary research teams are needed in which psychologists, as well as other social and behavioral scientists, work collaboratively with geneticists and other natural scientists.  相似文献

The transactional cognitive vulnerability to stress model Hankin & Abramson (Psychological Bulletin, 127:773–796, 2001) extends the traditional diathesis-stress model by proposing that the relationships among cognitions, depressive symptoms, and stressors are dynamic and bidirectional. In this study three different pathways among these variables were assessed simultaneously: (1) cognitive vulnerabilities and stressors as predictors of depressive symptoms (vulnerability model), (2) depressive symptoms and cognitive vulnerabilities as predictors of stressors (stress generation model), and (3) depressive symptoms and stressors as predictors of cognitive vulnerabilities (consequence model). A fully cross-lagged design panel was employed with 1,187 adolescents (545 girls and 642 boys, Mean Age?=?13.42 years) who were assessed at two time points separated by 6 months. They completed measures of cognitive vulnerabilities (maladaptive schema domains and negative inferential style), stressors, and depressive symptoms. Inferential style and schemas of the disconnection and rejection domain predicted prospective increases in depressive symptoms. Initial levels of depressive symptoms and most cognitive vulnerabilities predicted greater stress generation. Initial levels of stressors and depressive symptoms predicted an increase in negative inferential style and maladaptive schema domains over time. These bidirectional relationships were mostly similar for boys and girls, although there were a few gender differences. The findings support a transactional model with reciprocal relationships among stress, depressive symptoms, and cognitive vulnerabilities. Transactional implications for depression interventions among adolescents are discussed.  相似文献

Exploratory structural equation modeling (SEM) was applied to a multiple indicator (26 individual symptom ratings) by multitrait (ADHD-IN, ADHD-HI and ODD factors) by multiple source (mothers, fathers and teachers) model to test the invariance, convergent and discriminant validity of the Child and Adolescent Disruptive Behavior Inventory with 872 Thai adolescents and the ADHD Rating Scale-IV and ODD scale of the Disruptive Behavior Inventory with 1,749 Spanish children. Most of the individual ADHD/ODD symptoms showed convergent and discriminant validity with the loadings and thresholds being invariant over mothers, fathers and teachers in both samples (the three latent factor means were higher for parents than teachers). The ADHD-IN, ADHD-HI and ODD latent factors demonstrated convergent and discriminant validity between mothers and fathers within the two samples. Convergent and discriminant validity between parents and teachers for the three factors was either absent (Thai sample) or only partial (Spanish sample). The application of exploratory SEM to a multiple indicator by multitrait by multisource model should prove useful for the evaluation of the construct validity of the forthcoming DSM-V ADHD/ODD rating scales.  相似文献

Abstract

After briefly describing the purpose, structure, and functions of a typical family planning center, the paper suggests and gives support for a more relationship-centered service delivery system. The major thesis of the paper is that these centers should adopt a system which recognizes and promotes intimate human relationships, and that marriage and family counselors would be highly valuable resources in such a system. The paper stresses the importance of attending to the myriad relationship issues involved in the entire process of enabling individual couples to more effectively plan and control their own fertility. Several ways in which the marriage and family counselor can work with and within the family planning center are outlined.  相似文献

Abstract

Restructuring and downsizing are occurring increasingly throughout the workplace. As a result, many individuals are losing their jobs. Many others experience job insecurity as a result of the threat of downsizing. As with most other work spheres, several hospitals are closing, resulting in thousands of layoffs. Since nurses constitute one of the main groups employed in hospitals, they are faced with increasing job shortages. This study examines psychological reactions of nurses in response to stressors resulting from hospital downsizing. Individual resources, particularly coping strategies and self-efficacy, can affect the extent to which individuals experience distress as a result of downsizing. A self-report, anonymous questionnaire was filled out and returned by 1363 nurses employed in hospitals in Canada. Results of this study show that amount of work was a consistent and significant stressor in nurses. The greater the nurse's workload, the greater her emotional exhaustion, cynicism, depression and anxiety. Further results reported here indicated that control coping and self-efficacy lessened distress on the job and increased job satisfaction, while escape coping was associated with greater psychological distress and less job security.  相似文献

In biological vision systems, attention mechanisms are responsible for selecting the relevant information from the sensed field of view, so that the complete scene can be analyzed using a sequence of rapid eye saccades. In recent years, efforts have been made to imitate such attention behavior in artificial vision systems, because it allows optimizing the computational resources as they can be focused on the processing of a set of selected regions. In the framework of mobile robotics navigation, this work proposes an artificial model where attention is deployed at the level of objects (visual landmarks) and where new processes for estimating bottom-up and top-down (target-based) saliency maps are employed. Bottom-up attention is implemented through a hierarchical process, whose final result is the perceptual grouping of the image content. The hierarchical grouping is applied using a Combinatorial Pyramid that represents each level of the hierarchy by a combinatorial map. The process takes into account both image regions (faces in the map) and edges (arcs in the map). Top-down attention searches for previously detected landmarks, enabling their re-detection when the robot presumes that it is revisiting a known location. Landmarks are described by a combinatorial submap; thus, this search is conducted through an error-tolerant submap isomorphism procedure.  相似文献
