潜艇环境对艇员认知功能和作业能力的影响

本研究运用基础心理实验仪器和国际标准的韦克斯勒成人智力、记忆量表(中国修订版),对海军某潜艇艇员和岸勤人员进行了部分认知功能和作业能力的逐个测量。通过对照研究,探讨了潜艇环境对艇员注意力、领悟力、记忆力和作业能力的影响特点。发现:(1)潜艇艇员选择反应时测验,对3种声音反应错误次数多,尤其是低音错误多,说明潜艇艇员的低音听觉和判断力受到了明显的影响,军龄大于5年的多期士官影响显著。(2)潜艇艇员注意集中能力测验,脱靶次数多,且只是军龄小于2年的士兵表现显著,注意分配能力测验中对光反应错误次数多,但随着军龄的增加影响不明显。(3)潜艇艇员领悟理解能力差,上艇5年以上是艇员领悟力开始受损的重要时期。(4)潜艇艇员双手协调和手指灵活用时较短,但出轨和掉针次数略多,艇员双手作业速度在潜艇的岗位训练中得到了增强,但因潜艇环境的不利影响其准确性有待提高。     

Superior fluid intelligence in children with Asperger's disorder

Asperger's disorder is one of autistic spectrum disorders; sharing clinical features with autism, but without developmental delay in language acquisition. There have been some studies of intellectual functioning in autism so far, but very few in Asperger's disorder. In the present study, we investigated abstract reasoning ability, whose form of intelligence has been labeled fluid intelligence in the theory of Cattell [Cattell, R. B. (1963). Theory of fluid and crystallized intelligence: A critical experiment. Journal of Educational Psychology, 54, 1-22.], in children with Asperger's disorder. A test of fluid intelligence, the Raven's Standard Progressive Matrices Test, was administered to 17 children with Asperger's disorder and 17 age-, gender-, and FIQ-matched normal children. The results showed that children with Asperger's disorder outperformed on the test of fluid reasoning than typically developing children. We suggest that individuals with Asperger's disorder have higher fluid reasoning ability than normal individuals, highlighting superior fluid intelligence.     

Social cognitive predictors of college students’ academic performance and persistence: A meta-analytic path analysis

This study tested Social Cognitive Career Theory’s (SCCT) academic performance model using a two-stage approach that combined meta-analytic and structural equation modeling methodologies. Unbiased correlations obtained from a previously published meta-analysis [Robbins, S. B., Lauver, K., Le, H., Davis, D., & Langley, R. (2004). Do psychosocial and study skill factors predict college outcomes? A meta-analysis. Psychological Bulletin, 130, 261–288.] were used to create the input correlation matrices for subsequent path-analytic tests of the model, using both college GPA and retention as performance criteria. Results suggested that SCCT does an adequate to excellent job of modeling academic performance and persistence, but that model fit was better when general cognitive ability versus high school GPA was used to operationalize the ability/past performance variable. Results are discussed in terms of their fit with SCCT and their practical implications.     

浅谈科主任非权力性影响力的培养

科主任的非权力性影响力是由本人的素质和行为造成的,也可以说是个人的影响、威望和威信,这主要靠领导者具有良好的品格、素质和能力。本文就科主任应具备的良好的职业道德和人格魅力、丰富的才能和渊博的知识、良好的自制能力和人际关系、严谨的工作作风和高超的专业技术等这些非权力影响力进行了分析,并对如何提高这些素质进行了阐述。     

组织创新气氛的测量及其在员工创新能力与创新绩效关系中的调节效应

首先通过对46名在职MBA研究生的开放式问卷数据进行质性分析, 归纳探索出了基于我国国情的组织创新气氛的基本结构, 并参定预试测332份数据的反馈结果编制了组织创新气氛问卷。483份有效数据的探索性因素分析发现组织创新气氛是一个包括激励机制、领导躬行、团队协力、上级支持、资源保障、组织促进、自主工作等在内的七因素模型。为进一步验证该结构的有效性, 我们在10家企业共获得有效数据413份, 进行了验证性因素分析, 结果显示: 基于中国文化背景编制的组织创新气氛问卷具有良好的效度和信度; 同时, 运用层次回归分析还发现, 组织创新气氛在员工创新能力与创新绩效关系中具有显著的调节作用。     

儿童能力概念发展的研究述评

近二三十年来,有关儿童能力概念的研究主要分别从能力的跨时间和跨情境的稳定性、能力的效力和能力的不可控性3个维度较为深入地探讨了儿童能力概念的发展特点与趋势。但在儿童能力概念的研究中,对上述3个维度的整合性研究较为缺乏,而且能力概念的内涵及其构成等问题也有待于进一步的探讨。     

学业情绪及其影响因素

学业情绪是指在教学或学习过程中,与学生学业相关的各种情绪体验。个体的自我认知、成就目标、认知能力等个体因素以及班级、家庭、课堂等环境因素都会影响学业情绪,且自我认知是环境因素影响其学业情绪的一个重要中介变量。另外,学业情绪具有领域特异性。未来研究的方向主要在于学业情绪的界定和具体结构的深入探讨、学业情绪的发展特点、对特殊群体学生学业情绪的关注以及积极探索有效的干预措施等方面     

小学生空间能力及其发展倾向的性别差异研究

本研究探讨了二、四、六年级小学生空间能力的性别差异表现特征.结果表明,在空间能力的加工方式、加工精确性及加工策略上均存在着性别差异,而在加工速度上表现为无差现象.在空间能力的发展趋势和空间组合能力方面,女生表现出稳定的优势;在空间旋转能力上,男生的优势随年龄增长表现为减弱并消失的特征.     

Accounting for the shared environment in cognitive abilities and academic achievement with measured socioecological contexts

Behavioral and molecular genetic research has established that child cognitive ability and academic performance are substantially heritable, but genetic variation does not account for all of the stratification of cognitive and academic outcomes across families. Which specific contexts and experiences contribute to these shared environmental influences on cognitive ability and academic achievement? Using an ethnically and socioeconomically diverse sample of N = 1728 twins ages 7–20 from the Texas Twin Project, we identified specific measured family, school, and neighborhood socioecological contexts that statistically accounted for latent shared environmental variance in cognitive abilities and academic skills. Composite measures of parent socioeconomic status (SES), school demographic composition, and neighborhood SES accounted for moderate proportions of variation in IQ and achievement. Total variance explained by the multilevel contexts ranged from 15% to 22%. The influence of family SES on IQ and achievement overlapped substantially with the influence of school and neighborhood predictors. Together with race, the measured socioecological contexts explained 100% of shared environmental influences on IQ and approximately 79% of shared environmental influences on both verbal comprehension and reading ability. In contrast, nontrivial proportions of shared environmental variation in math performance were left unexplained. We highlight the potential utility of constructing “polyenvironmental risk scores” in an effort to better predict developmental outcomes and to quantify children's and adolescents’ interrelated networks of experiences.

工作记忆刷新训练改善抑郁倾向大学生情绪调节能力的HRV证据

根据流调中心用抑郁量表(CES-D)和贝克抑郁量表(BDI-II-C)的得分情况招募健康被试20例, 抑郁倾向被试40例, 以自愿参加的分组方式将抑郁倾向被试分为工作记忆刷新训练组和对照组, 每组20例。对训练组进行为期20天的工作记忆刷新训练, 对照组不做处理。记录各组被试在前后测的刷新功能以及在情绪调节任务中量表的得分情况, 并收集各组被试在5种实验条件下的心率变异性(HRV)的频域指标值, 结果发现：前测时抑郁倾向个体的HF-HRV显著低于健康个体的平均水平。经过工作记忆训练, 后测的抑郁倾向训练组在情绪调节任务中的HF-HRV水平有显著的提高, 贴近健康对照组的水平, 并与抑郁倾向对照组分离。研究表明, 工作记忆刷新训练能够使抑郁倾向大学生的HRV活动更接近健康被试的HRV活动, 表明抑郁倾向大学生的情绪调节能力得到了改善。
