视知觉无意识对局部形状和颜色特征加工的注意调节

研究了视知觉无意识对局部几何特征加工中的整体优势效应.被试为天津师范大学本科生60名.仪器为pentium III高分辨率计算机,程序用E-prime心理实验软件系统编制而成.被试的任务是判断靶图形中央线条的方向或颜色.用MANOVA分析了启动图形对靶图形局部特征加工的启动效应,发现了视知觉对无意识呈现的图形加工具有形状优势效应,启动图形与靶图形的整体形状相同可以抑制对靶图形局部形状特征的判断.当被试的任务变成判断靶线条的颜色或启动图形的边由连通状态变成不连通时,视知觉无意识对启动图形加工的整体优势效应消失.该结果提示整体优势效应很可能与任务涉及的信息通道密切相关,对局部形状特征的注意很可能涉及对周围整体形状信息加工自动抑制的过程.     

More efficient parameter estimates for factor analysis of ordinal variables by ridge generalized least squares

Data in psychology are often collected using Likert‐type scales, and it has been shown that factor analysis of Likert‐type data is better performed on the polychoric correlation matrix than on the product‐moment covariance matrix, especially when the distributions of the observed variables are skewed. In theory, factor analysis of the polychoric correlation matrix is best conducted using generalized least squares with an asymptotically correct weight matrix (AGLS). However, simulation studies showed that both least squares (LS) and diagonally weighted least squares (DWLS) perform better than AGLS, and thus LS or DWLS is routinely used in practice. In either LS or DWLS, the associations among the polychoric correlation coefficients are completely ignored. To mend such a gap between statistical theory and empirical work, this paper proposes new methods, called ridge GLS, for factor analysis of ordinal data. Monte Carlo results show that, for a wide range of sample sizes, ridge GLS methods yield uniformly more accurate parameter estimates than existing methods (LS, DWLS, AGLS). A real‐data example indicates that estimates by ridge GLS are 9–20% more efficient than those by existing methods. Rescaled and adjusted test statistics as well as sandwich‐type standard errors following the ridge GLS methods also perform reasonably well.     

心理资本与工作绩效的关系:基于本土心理资本理论的视角

采用问卷调查法,以445名企业员工和MBA学员为调查对象,考察了本土心理资本与适应性绩效的关系。结果表明:(1)本土心理资本对任务绩效和周边绩效均有显著的预测作用;其中事务型心理资本对任务绩效的预测作用较强;而人际型心理资本对周边绩效的预测作用较强。(2)本土心理资本对适应性绩效有显著的正向预测作用;其中事务型心理资本主要影响了压力与应急管理、创新问题解决、岗位持续学习等维度,而人际型心理资本则主要影响了人际与文化适应和岗位持续学习等维度。(3)适应性绩效在事务型和人际型心理资本与周边绩效间起部分中介作用,在事务型心理资本与任务绩效间也起部分中介作用。(4)在控制事务型心理资本的前提下,人际型心理资本对适应性绩效和周边绩效仍有显著的预测作用,显示人际型心理资本的构念具备实证效度。     

发散思维的序列位置效应：创新想法动态产生机制的新视角

发散思维的序列位置效应是指随着时间的推移,单位时间内想法生成的数量逐渐降低,但想法的独创性逐渐升高的现象。联想理论和执行控制假说分别侧重对序列位置效应的个体差异和认知加工过程进行解释。神经影像学研究表明,在想法产生的整个阶段序列位置效应依赖于默认网络后部和突显网络的持续增强激活和协同合作;在想法产生的后期阶段,颞-顶区域alpha能量值以及执行控制网络与默认网络的协同模式增强。未来研究需要结合语义和神经动态分析等技术,对序列位置效应的特异性机制、动态加工机制以及影响因素进行深入探究,从而为解构创新思维的动态过程提供新的视角。     

Is Disciplinary Culture a Moderator Between Materialism and Subjective Well-being? A Three-Wave Longitudinal Study

To clarify the influence of disciplinary culture on the materialism–subjective well-being (SWB) relationship, as well as the relationship between changes in materialism and changes in SWB, the current longitudinal study tracked the levels of materialism and SWB among first-year undergraduates for 12 months. A total of 218 participants from a congruent disciplinary culture (i.e., business school) and 210 participants from an incongruent disciplinary culture (i.e., engineering school) provided ratings on the Material Values Scale, the Satisfaction with Life Scale, and the Positive and Negative Affect Schedule in three waves. The following results were obtained: (1) the interaction effect of disciplinary culture and time was significant. In Wave 3, the level of materialism in business school was significantly higher than that in engineering school, but this difference was not found in Waves 1 and 2; (2) the negative relationship between materialism and SWB remained stable over time and was not moderated by disciplinary culture. Moreover, disciplinary culture did not moderate the relationship between changes in materialism and changes in SWB. The above findings indicate that disciplinary culture influences the development of materialism but not the materialism–SWB relationship in the long term.     

青少年早期学业成就的同伴团体社会化:感知学校氛围的调节作用

通过对1275名初一青少年开展为期半年的追踪调查,考察了同伴团体对青少年早期个体学业成就的影响,及感知学校氛围对这种影响的调节作用。结果表明:(1)在控制学校虚拟变量、年龄、性别、同伴团体规模及个体前期学业成就之后,所在班级前期的平均学业成就能显著预测个体后期学业成就;(2)同伴团体的学业成就能正向预测个体后期的学业成就变化,但班级相对于同伴团体的情境效应不显著。(3)在个体和同伴团体水平,感知学校氛围各维度不能显著预测个体后期学业成就,但同伴团体平均学业成就与该团体整体感知到的教师支持的交互项可以正向预测个体学业成就间隔半年后的变化。     

Psychiatric Distress and Suicidal Tendencies in Adult Cancer Survivors: Verifying the Validity of the Brief Symptom Inventory-18 for Identifying Suicidal Ideation in the Hospitalized Population of Mainland China

The Brief Symptom Inventory-18 (BSI-18) is widely used to assess psychiatric distress but has not been verified in the Chinese population. From March to April 2019, 293 hospitalized cancer patients, aged 20–87, completed the cross-sectional survey with demographics questionnaire, BSI-18, and PHQ-9. We analyzed the single suicide-related item of PHQ-9 with the full score clinical outpoint for BSI-18 and PHQ-9 using SPSS 22.0 and R 2.15, including Pearson's χ² test and ROC curve analyses. A Pearson's χ² test was carried out to compare the three different methods with the gold screening criteria. The p-value was correspondingly to .006, .066, .838. When the PHQ-9?≥?10 criteria for the BSI-18, receiver operating characteristic analysis revealed that AUC values were 0.839, optimal cut-off points for both BSI-18?≥?50, the sensitivity of 85.8%, and 62.5%, respectively. The BSI-18 is suitable for a screening tool for psychological distress and could also be used in clinical settings for preliminary screening of hospitalized cancer patients.

     

同伴团体对青少年问题行为的影响：一项基于社会网络分析的研究

以675名初中和高中学生为被试,采用社会网络分析方法,获得506名青少年在其班级中的网络中心度,并确定他们所属的同伴团体,在此基础上考察同伴团体的行为规范对其问题行为的影响。结果发现：（1）在控制了班级层次的问题行为水平和其他相关变量后,同伴团体的问题行为水平能够正向预测青少年自身的问题行为;（2）青少年在同伴团体内部的地位能负向预测青少年的问题行为,青少年在班级社交网络中的度数中心度能正向预测其问题行为,而中介中心度能负向预测其问题行为;（3）交互作用分析表明：同伴团体的问题行为水平主要对低中介中心度的青少年产生显著影响;仅在问题行为水平较高的同伴团体中,青少年的度数中心度正向预测其问题行为。
