学习、频率和结构方式对汉字知觉干扰效应的影响

知觉干扰存效应是指之前更模糊的刺激的呈现对之后同一模糊刺激的识别的抑制。实验-考察了学习和频率、实验二考察了学习和结构方式对汉字知觉干扰存效应的影响。结果发现：1．汉字与图片一样,不存在材料有限现象,在学习和不学习条件下,汉字识别中均存在知觉干扰效应;2．学习以及频率和结构方式对汉字知觉干扰效应的影响也不显著;3．频率、学习和结构方式对汉字识别的影响显著。这些结果似乎表明当激活超过一定的水平时,和汉字激活水平有关的因素对知觉干扰效应不再起作用。失匹配假说可更好的解释激活水平的作用以及材料有限现象。

The nature of the memory buffer in implicit learning: Learning Chinese tonal symmetries

Previous research has established that people can implicitly learn chunks, which (in terms of formal language theory) do not require a memory buffer to process. The present study explores the implicit learning of nonlocal dependencies generated by higher than finite-state grammars, specifically, Chinese tonal retrogrades (i.e. centre embeddings generated from a context-free grammar) and inversions (i.e. cross-serial dependencies generated from a mildly context-sensitive grammar), which do require buffers (for example, last in-first out and first in-first out, respectively). People were asked to listen to and memorize artificial poetry instantiating one of the two grammars; after this training phase, people were informed of the existence of rules and asked to classify new poems, while providing attributions of the basis of their judgments. People acquired unconscious structural knowledge of both tonal retrogrades and inversions. Moreover, inversions were implicitly learnt more easily than retrogrades constraining the nature of the memory buffer in computational models of implicit learning.     

脑功能成像的新方法——功能性近红外光谱技术（fNIRS）

功能性近红外光谱技术（functional near-infrared spectroscopy, fNIRS）利用血液的主要成分对600-900nm近红外光良好的散射性,从而获得大脑活动时氧合血红蛋白和脱氧血红蛋白的变化情况。目前该技术开始运用于自然情境下的高级认知、发展心理学、异常心理学等多个领域的研究。该技术具有造价较低、便携性好,无噪音、无创性和对实验过程中被试动作不会过份敏感等优点,但也存在空间分辨率不高和校正算法有待进一步完善等方面的不足。未来fNIRS的研究可以与fMRI等其他成像技术进行结合,开展婴幼儿和特殊人群的认知神经科学研究以及自然情境下大脑认知的神经机制研究。     

当代大学生自比型价值观数据的潜在结构

本研究对采自3796名在校大学生的Rokeach Value Survey自比型数据进行了因素分析和多维尺度分析。因素分析从两组价值观选项中分别获得6个双极因素,虽然内容各不相同,但均体现出个人指向-亲社会指向的特点。多维尺度分析所获得的两组选项的2维空间距离分布结果也体现类似特点,结果显示终极性价值观可分为四类,工具性价值观可分为五类。当前大学生价值观中存在着舒适的物质生活、兴奋的生活、幸福、快乐和自尊以及雄心壮志的、勇敢的和诚实的等个人取向内容占优势的可能性。在两种分析方法中,多维尺度分析更适合对自比型价值观数据潜在结构的探究。     

企业员工职业承诺的结构模型研究

Screening of personality disorders among chinese college students by Personality Diagnostic Questionnaire-4+

Four thousand eight hundred and eleven students were sampled from 26 universities in 21 cities of China and evaluated using the Personality Diagnostic Questionnaire-4+(PDQ-4+). Results showed that male students obtained significantly higher scores than female students on paranoid, schizotypal, antisocial, narcissistic, passive-aggressive, and depressive personality disorder scales, and lower scores on the borderline scale. Students from rural areas scored higher than those from urban areas on the schizoid, schizotypal, narcissistic, avoidant, compulsive-obsessive, passive-aggressive, and depressive personality disorder scales, and lower on the paranoid and dependent scales. Singleton students obtained significantly higher scores than nonsingletons on paranoid, antisocial and dependent scales, and lower on schizoid, avoidant, compulsive-obsessive, passive-aggressive, depressive scales. Students from single-parent families scored significantly higher on the schizotypal scales; and students from foster families scored significantly higher on the antisocial, passive-aggressive, and depressive scales. Students from poor families scored significantly higher than those from average or wealthy families on schizoid, schizotyal, antisocial, borderline, narcissistic, avoidant, obsessive-compulsive, passive-aggressive, and depressive personality disorders. The results suggest that low family income, low social status, and parental style contribute to the development of personality disorders.     

图片和汉字的激活水平及知觉干扰效应的比较

研究使用8个残缺水平下的图片及其中文名（汉字双字词）为实验材料．试图比较图片与汉字双字词识别激活水平的差异,接着比较二者产生知觉于扰效应的条件,并把二者产生知觉于扰的条件与英文单词产生知觉于扰的条件进行比较。实验一结果发现,在材料较清晰的条件下,汉字双字词的命名成绩高于图片,表明汉字双字词的激活水平不比图片低,但在材料很残缺的条件下,汉字双字词的命名成绩低于图片。实验二发现双字词和图片在没有事先学习情况下都产生知觉干扰效应,已有研究表明单个汉字无需事先学习也可以产生干扰效应,而英文单词需要事先学习。因此,图片和汉字的干扰效应与英文单词的差别跟图片、汉字的激活水平比英文单词高有关。     

领导行为对员工创造力的影响:基于变量中心和个体中心的视角*

以10家IT企业的305名员工为被试,采用变量中心和个体中心的分析策略,考察领导行为对员工创造力的影响。变量中心的分析发现,变革领导行为和交易领导行为均显著正向预测员工创造力。个体中心的分析发现,中变革/中交易与(中、低)被动结合的领导类型最为普遍,占全部领导的69.2%;无论被动放任行为高低,高变革与高交易行为组合领导下的员工创造力最高,说明高变革和高交易领导行为的结合最有利于员工创造力,领导类型对员工创造力的影响主要由使用变革和交易这两种领导行为的程度所决定。
