内隐社会认知的初步实验研究

使用攻击和被攻击者相互作用的实验图片,随机抽取大学本科生９０名,采用３种加工类型×２种测验方式的混合设计来考察社会认知的无意识或内隐成分。结果表明：１．加工类型对被试的再认测验和偏好测验有不同的影响,即出现了实验性分离;２．内隐态度是可以测量的,且明显影响被试的社会判断     

哪个测验Q矩阵更合理:基于DINA模型测验Q矩阵合理性侦查指标及其比较与应用

本研究对多个测验Q矩阵的相对合理性的比较与选用开展研究,采用Monte Carlo模拟与实证研究相结合的范式,探讨R_square、HCI、-2LL、AIC、BIC、residual、ABS_residual及本研究新开发的BIC2等八项指标在测验Q矩阵合理性侦查效果及其比较。研究发现:八项指标中,除BIC和BIC2两项指标的对测验Q矩阵相对合理性的平均正确识别率在95%以上,其余指标的平均正确识别率不足90%,整体而言,考虑样本容量及参数个数双重加权的BIC和BIC2两项指标的表现总体上优于其它几项指标;各项指标在不同Q矩阵错误类型下其正确识别率也不尽相同。     

CTT与IRT方法对人格测验结果处理的比较研究

为了说明使用经典测量理论(CTT)方法和项目反应理论(IRT)方法计算出的人格测验结果的差异,本研究使用IRT和CTT这两种方法分别计算出模拟人格测验和实际人格测验的测验结果,并对此进行比较。研究表明,两种不同的方法得到的测验结果之间平均有0．11个标准差以上的差异。进一步研究发现,在对测验结果进行分析时,IRT方法比CTT方法更为有效。     

特里尔社会应激测验对儿童皮质醇分泌的影响

研究以32名小学儿童（平均年龄10.47岁,男生16人）为被试,采用唾液皮质醇为应激测验的客观指标、以被试主观紧张度为主观指标,考察特里尔社会应激测验对中国儿童皮质醇分泌的影响。结果表明：（1）社会应激测验任务引发儿童皮质醇浓度和主观紧张度的显著上升,任务后的恢复期皮质醇浓度和主观紧张度能够恢复到任务前的水平。（2）社会应激测验任务引发的男生皮质醇水平变化显著高于女生,但是引发的主观紧张度水平变化不存在显著性别差异。社会应激测验中文修订版能够有效引发儿童的压力应激变化,可以用其开展儿童社会应激的相关研究。     

Evidence of a Flynn Effect in Children's Human Figure Drawings (1902–1968)

The Flynn effect is the long-term trend for scores on tests of cognitive ability to increase across cohorts. Several samples of children's human figure drawings, published in 1902, 1926, 1963, and 1968, are examined for evidence of a Flynn effect. Results show that larger percentages of children draw more complete human figures over the course of the 20th century.     

学习困难青少年认知控制特点研究

本研究基于双重认知控制理论,通过比较学困组和对照组在持续性操作任务上的表现来探究学习困难青少年的认知控制特点。结果发现：（1）在反应性控制的指标上,学困组和对照组的反应时和正确率不存在显著差异,但学困组对探测刺激的辨别力指数更低,显示学困组的反应性控制能力存在一定不足;（2）在主动性控制的指标上,学困组的反应时更长、正确率更低,且对线索刺激的辨别力指数更低,显示学困组在对线索刺激保持的各项指标上都比对照组更差,说明学困组在主动性控制上的缺陷更为明显。     

Image du corps chez l’enfant sourd. Perception et vécu à travers le dessin et le TSEA

The body is as a living entity with three interrelated aspects: the physical motor skills, development processes, social and emotional interaction. The young child, regardless of his mental or physical condition, appropriates this entity when he is in contact with the surrounding world. Thus, the self-image will depend, in large part, on the person he is, the situation in which he lives (society, family), the nature and frequency of surrounding stimuli. A child carrying a handicap is likely to have a poor representation of his own self-image (disproportionate or deformed body) and an altered self-image, as far as he lives in a rejecting environment. In this paper, we have focused our research on how deaf children sees their self-image, based on our nineteen years of experience as a psychologist with hearing impaired children, in special schools. The various observations and assessments in this research, in addition to groups support offered to parents during all these years, give us today enough elements to show what kind of self-image the deaf child has of himself. Our assessment material was essentially thematic projective test of socialization –TSEA– and the drawing of the person.

Extreme elemental processing in a high schizotypy population: Relation to cognitive deficits

The cognitive deficits observed in schizophrenia have been characterized as a failure to utilize task-setting information to guide behaviour, especially in situations in which there is response conflict. Recently, we have provided support for this account; high schizotypy individuals demonstrated inferior biconditional discrimination performance compared to low scorers, but were not impaired on a simple discrimination that did not require the use of task-setting cues. These results may, however, also be explained by the way in which individuals with high schizotypy process stimulus compounds. Here, we examine the initial approaches to solving biconditional and control discrimination tasks of participants with high and low schizotypy scores. In particular, we focus on performance during the first block of training trials to capture processing style before the acquisition of the discrimination tasks. Participants scoring highly on the introvertive anhedonia subscale (which has been allied to the negative and cognitive symptoms of schizophrenia) demonstrated better biconditional performance during the first block of training trials than did low-schizotypy individuals, consistent with a highly elemental approach to stimulus processing. Subsequent recognition tests confirmed this analysis demonstrating that the pattern of performance observed in participants with high schizotypy was associated with a failure to discriminate conjunctions of items that had been seen before from those that had not. These results suggest that the negative/cognitive symptoms of schizophrenia may reflect an extreme bias towards elemental, as opposed to configural, processing of stimulus conjunctions.
