Hemispheric asymmetry effects in children studied by dichotic listening and visual half-field testing

Dichotic listening (DL) and visual half-field (VHF) testing were used to study hemisphere asymmetry in a developmental perspective. Five-, 8-, and 11-year-old children were presented lists of fused words using a DL technique in Experiment 1, and 8- and 11-year-old children were presented pictures of common objects using a VHF technique in Experiment 2. In both experiments, measures of identification, free recall, and recognition of the words/pictures were employed. The results revealed effects of ear input (right-ear advantage) and half-field presentation (right visual half-field advantage) for all age groups, although the magnitude of this lateralization effect differed between the three memory measures. The results are discussed in relation to developmental aspects of language laterality, and in relation to the clinical utility of non-invasive lateralization techniques.     

Learning a two-cue inference task when one of the cue-criterion relations is known

Learning two-cue probability learning (MPL) tasks when the functional relation between the first cue and the criterion was known to the subject was studied in a factorial experiment. Contrary to the predictions from a hypothesis sampling model assuming independent learning of each cue in MPL, the function form for the first cue was found to affect learning of the second cue, facilitating it when the functional relations were the same for both cues and inhibiting it when the functions were different. These results suggest that it is not possible to extrapolate findings from single-cue probability learning directly to MPL.     

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。     

Illness perception patterns in patients with Coronary Artery Disease

The purpose of this study is to identify patterns of illness perception in patients with angiografically verified Coronary Artery Disease. A total of 166 patients (age: 64.4 ± 12.1, 80.7% male) were recruited after angiography. Cluster analysis on the items of the Brief Illness Perception Questionnaire was used to identify patterns of illness perception. The resulting groups were characterized with regard to Quality of Life (MacNew), anxiety and depression (GAD-7 and PHQ-9) and resilience (RS-13). The analysis revealed 4 distinct groups differing with regard to the items covering the perception of the physical and emotional impact of disease. Stronger perceptions in these domains were associated with lower Health Related Quality of Life and higher levels of emotional distress. Group 1 (33.1%) reported the strongest perceptions of the physical and emotional impact of disease and expressed low treatment control, high chronic timeline and significantly higher levels of depression than the other groups. Group 2 (27.7%) was characterized by more moderate perceptions of the emotional and physical impact of disease together with low scores on illness coherence and chronic timeline. Groups 3 (25.3%) and 4 (13.9%) reported smaller physical and emotional impact of illness but differed in chronic timeline. Our results correspond largely to recent findings in patients with other chronic diseases. Further research is needed to explore if stratification of patients according patterns of illness perception can help to inform patient–physician communication strategies.     

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.     

Detecting deception: the scope and limits

With the increasing interest in the neuroimaging of deception and its commercial application, there is a need to pay more attention to methodology. The weakness of studying deception in an experimental setting has been discussed intensively for over half a century. However, even though much effort has been put into their development, paradigms are still inadequate. The problems that bedevilled the old technology have not been eliminated by the new. Advances will only be possible if experiments are designed that take account of the intentions of the subject and the context in which these occur.
