回忆任务对合作抑制和错误修剪的调节——情绪效价和编码水平的影响

前人在项目回忆条件的合作记忆研究中记录到明显的合作抑制和错误修剪,背景提取条件的相关研究尤显不足;同时,情绪效价和编码水平对两类现象调节的研究尚未涉及。为此,本文在两个实验中采用经典合作记忆研究范式,以不同情绪效价的词汇为实验材料并以词汇在学习阶段的呈现颜色为背景展开研究。实验1和实验2分别在学习阶段采用了深编码和浅编码任务,回忆阶段则均含项目回忆(回忆已学词汇)和背景提取(回忆词汇在学习阶段的呈现颜色)两种任务。采用深编码条件的实验1的结果显示,项目回忆比背景提取条件的合作抑制更强、错误修剪更弱,回忆任务与词汇情绪效价交互影响合作抑制强度;采用浅编码条件的实验2则发现错误修剪在两种任务间的差异不显著。两实验的联合分析显示,回忆任务与编码水平交互影响合作抑制和错误修剪强度。上述结果表明:回忆任务对合作抑制和错误修剪的调节支持双重加工模型;回忆任务与情绪效价对合作抑制强度的交互影响支持权衡说,且与双重加工模型相吻合;回忆任务与编码水平交互影响合作抑制和错误修剪强度。     

Neural correlates of rumination in adolescents with remitted major depressive disorder and healthy controls

The aim of the present study was to use fMRI to examine the neural correlates of engaging in rumination among a sample of remitted depressed adolescents, a population at high risk for future depressive relapse. A rumination induction task was used to assess differences in the patterns of neural activation during rumination versus a distraction condition among 26 adolescents in remission from major depressive disorder (rMDD) and in 15 healthy control adolescents. Self-report depression and rumination, as well as clinician-rated depression, were also assessed among all participants. All of the participants recruited regions in the default mode network (DMN), including the posterior cingulate cortex, medial prefrontal cortex, inferior parietal lobe, and medial temporal gyrus, during rumination. Increased activation in these regions during rumination was correlated with increased self-report rumination and symptoms of depression across all participants. Adolescents with rMDD also exhibited greater activation in regions involved in visual, somatosensory, and emotion processing than did healthy peers. The present findings suggest that during ruminative thought, adolescents with rMDD are characterized by increased recruitment of regions within the DMN and in areas involved in visual, somatosensory, and emotion processing.     

Influence of Counselor Spirituality and Training on Treatment Focus and Self‐Perceived Competence

Spirituality is a potential area of concern for counseling clients. This study presents the empirical results of a survey completed by 572 counselors to determine if counselors' spiritual beliefs, experiences, or training had an impact on their focus of therapy or self‐perceived competence. A counselor's personal spirituality, spiritual experience, and spirituality training did significantly influence treatment focus as well as self‐perceived competence to counsel a client with spiritual concerns.     

心理资本: 本土量表的开发及中西比较

开发了本土心理资本量表, 并将之与西方量表进行了比较。结果显示, 本土心理资本构念具有二阶双因素结构: 事务型心理资本(自信勇敢、乐观希望、奋发进取与坚韧顽强)与人际型心理资本(谦虚诚稳、包容宽恕、尊敬礼让与感恩奉献)。事务型心理资本与西方心理资本基本相似, 人际型心理资本则具有本土文化气息。本土量表具有良好的效标关联效度, 人际型心理资本、事务型心理资本和任务绩效、周边绩效、工作满意度、工作投入及组织承诺显著正相关, 人际型心理资本与传统性、相依我正向关系显著。相比西方量表, 本土量表的信效度更好, 对工作绩效有更强的解释能力, 尤其是对周边绩效。建议进行心理资本研究时应充分考虑中西文化差异, 对组织而言, 则应重视对雇员本土心理资本各要素的开发与管理。     

专业社会工作介入社会性突发事件精神救助限制与突破

精神救助与物质救助一样.是社会性突发事件处置中一个当然的组成部分.在我国现实国情下,专业社会工作介入社会性突发事件精神救助在其理论研究与实践过程中都会暂时存在较难逾越的屏障.面对社会接受和专业自身发展所表现出来的诸多限制,专业社会工作要成功地介入社会性突发事件精神救助,发挥其优势作用,政府重视是前提,社会工作服务的本土化是根本,专业队伍建设是关键,积极行动是途径.     

Constructive and unconstructive repetitive thought

The author reviews research showing that repetitive thought (RT) can have constructive or unconstructive consequences. The main unconstructive consequences of RT are (a) depression, (b) anxiety, and (c) difficulties in physical health. The main constructive consequences of RT are (a) recovery from upsetting and traumatic events, (b) adaptive preparation and anticipatory planning, (c) recovery from depression, and (d) uptake of health-promoting behaviors. Several potential principles accounting for these distinct consequences of RT are identified within this review: (a) the valence of thought content, (b) the intrapersonal and situational context in which RT occurs, and (c) the level of construal (abstract vs. concrete processing) adopted during RT. Of the existing models of RT, it is proposed that an elaborated version of the control theory account provides the best theoretical framework to account for its distinct consequences.

TouchStat v. 3.00: A new and improved Monte Carlo adjunct for the sequential touching task

The sequential-touching procedure is employed by researchers studying nonlinguistic categorization in toddlers. TouchStat 3.00 is introduced in this article as an adjunct to the sequential-touching procedure, allowing researchers to compare children's actual touching behavior to what might be expected by chance. Advantages over the Thomas and Dahlin (2000) framework include ease of use, and fewer assumptive limitations. Improvements over TouchStat 1.00 include calculation of chance probabilities for multiple "special cases" and for immediate intercategory alternations. A new feature for calculating mean run length is also included.     

Assessing Children's Homework Performance: Development of Multi-Dimensional, Multi-Informant Rating Scales

Efforts to develop interventions to improve homework performance have been impeded by limitations in the measurement of homework performance. This study was conducted to develop rating scales for assessing homework performance among students in elementary and middle school. Items on the scales were intended to assess student strengths as well as deficits in homework performance. The sample included 163 students attending two school districts in the Northeast. Parents completed the 36-item Homework Performance Questionnaire — Parent Scale (HPQ-PS). Teachers completed the 22-item teacher scale (HPQ-TS) for each student for whom the HPQ-PS had been completed. A common factor analysis with principal axis extraction and promax rotation was used to analyze the findings. The results of the factor analysis of the HPQ-PS revealed three salient and meaningful factors: student task orientation/efficiency, student competence, and teacher support. The factor analysis of the HPQ-TS uncovered two salient and substantive factors: student responsibility and student competence. The findings of this study suggest that the HPQ is a promising set of measures for assessing student homework functioning and contextual factors that may influence performance. Directions for future research are presented.     

Suicide risk screening in an urban high school

Qualitative data from an empirical study of adolescent suicide risk were analyzed to examine the screening component built in to a larger protocol. It was determined that a significant number of students were being identified as being in need of follow-up. Although the majority (88.7%) of students screened met criteria for placement in the no indicators (of risk) category, 3.8% evidenced apparent need of follow-up, 4.4% qualified for notable concern, and 3.1% were deemed to be at-risk or in crisis. Several gender and ethnic differences in risk category status are also discussed. The system utilized at the school and examples of the range of interventions utilized are discussed. Evidence for the positive effects of this screening on individual students and the school as a whole are presented. Arguments for the regular use of screening measures in high schools and suggestions for implementation are also given.
