The effect of viewing distance on empirical discriminability and the confidence–accuracy relationship for eyewitness identification

The distance from which an eyewitness views a perpetrator is a critical factor for eyewitness identification, but has received little research attention. We presented three mock-crime videos to participants, varying distance to three perpetrators (3, 10, or 20 m). Across two experiments, increased distance reduced empirical discriminability in the form of a mirror effect, such that correct identifications decreased while false identifications increased. Moreover, high confidence identifications were associated with high accuracy at 3 m (Experiment 1 and 2) and 10 m (Experiment 2), but not at 20 m. We conclude that eyewitnesses may be less likely to identify a perpetrator viewed at a distance, and also more likely to falsely identify an innocent suspect. Furthermore, there may be certain boundary conditions associated with distance and the impact it has on the confidence–accuracy relationship. More research is needed to elucidate the effect of estimator variable manipulations on the confidence–accuracy relationship.     

Chronic fatigue syndrome/myalgicencephalomyelitis as a twentieth-century disease: analytic challenges

The challenges of chronic fatigue syndrome (often called myalgic encephalomyelitis, especially in the UK) (CFS/ME) to analytical and medical approaches are connected with our inability to understand its distressing somatic symptoms in terms of a single identifiable and understandable disease entity. The evidence for the roles of viral aetiologies remains inconclusive, as does our understanding of the involvement of the immune system. The history and social context of CFS/ME, and its relation to neurasthenia and psychasthenia are sketched. A symbolic attitude to the condition may need to be rooted in an awareness of psychoid levels of operation, and the expression and spread of CFS/ME may sometimes be aided by the ravages of projective identification. Psychic denial, sometimes violent, in sufferers (especially children and adolescents) and their families may be important in the aetiology of CFS/ME. We draw out common threads from psychodynamic work with five cases, four showing some symptomatic improvement, analytic discussions of three cases being presented elsewhere in this issue of JAP.     

National glorification and attachment differentially predict support for intergroup conflict resolution: Scrutinizing cross-country generalizability

Research on national identity distinguishes between national glorification and attachment. We tested whether glorification and attachment differentially predicted support for military and diplomatic conflict resolution strategies (CRS) in response to international conflicts. Using data collected in seven countries (Australia, United States, United Kingdom, France, Germany, Israel, China; total N = 1784), we investigated whether glorification and attachment can be equivalently measured (using tests of measurement invariance) and whether their relationships with CRS were generalizable across countries. The results revealed metric, but not scalar, measurement invariance of the two-factor structure of national identification across six countries, excluding China. Among these six countries, glorification predicted more support for military CRS, whereas attachment predicted more support for diplomatic CRS. Our study is novel in scrutinizing the cross-cultural generalizability of the bi-dimensional model of national identification. Implications for studying national identification and intergroup conflict cross-culturally are discussed.     

组织认同一定会促进亲组织非伦理行为吗？社会责任型人力资源管理的作用

基于社会认同理论,以社会责任型人力资源管理作为组织道德性的线索,探讨其对组织认同与亲组织非伦理行为之间关系的调节作用及其对亲组织非伦理行为的直接影响。采用多层线性建模技术进行数据分析,结果表明：当社会责任型人力资源管理水平低时,组织认同正向影响亲组织非伦理行为;当社会责任型人力资源管理水平高时,组织认同对亲组织非伦理行为没有显著影响;社会责任型人力资源管理对亲组织非伦理行为具有抑制作用。     

词汇习得年龄和频率对词汇识别的影响

三个实验考察词汇习得年龄和频率在词汇识别中的作用。实验结果表明：词汇习得年龄是影响汉语双字词词汇识别的重要因素,表现为早期习得的词汇比晚期习得的词汇更具有加工的优势。词汇习得年龄和频率独立地影响汉语双字词的识别过程．它们之间的效应是一种相加的关系。本研究还对词汇习得年龄效应的机制进行了讨论。

负性情境诱导下抑郁个体的情绪Stroop效应：ERPs研究

运用ERPs技术探讨了正常和抑郁个体在中性和负性情境诱导下的情绪Stroop效应。结果发现正常被试在负性情境下对中性词判断的错误率比在中性情境下更高,对负性词加工的P1波幅减小、N1增大,出现了Stroop效应;抑郁被试在两种情境下对负性词加工的P1和 N1波幅没有差异。研究结果提示,抑郁个体在负性情境下出现注意脱离困难和资源不足,难以解决情绪冲突任务,支持了注意脱离损伤假说,并进一步说明抑郁个体的情绪选择性注意加工会受到心境一致性状态的影响,因过多的注意资源卷入从而出现负性情绪调节不良。实验结果为探讨抑郁个体对负性情绪的注意加工和调节过程提供了来自电生理的证据。     

单字词的学习年龄对小学生汉字识别的影响（Ⅰ）

该研究以小学一、三、五年级的学生为被试,采用字词的真假判断任务,选取分别在语文课本中一、三、五年级出现的三组字(分别记为A、B、C三组字)为真字,考察了单字词的学习年龄(LA)对小学生汉字识别时间的影响。结果表明：无论纵向比较还是横向比较,单字词的学习年龄(LA)对小学生的真假字判断反应时都有显著影响。
