工科院校大学生自我和谐感与人际交往能力的关系研究 总被引:2,自引:0,他引:2
采用自我和谐量表(SCCS)和自编的大学生人际交往能力量表,研究工科院校大学生自我和谐的状况、人际交往状况以及两者的相关。发现人际交往能力的整体状况对自我和谐状况有一定的预测作用,大学生文理科差异会导致其自我和谐状况出现差异,且不良的人际交往能力会引发自我的不和谐。 相似文献

以34名五年级儿童为被试,采用出声思维法考查了阅读材料类型和难度对儿童阅读策略使用情况的影响。结果发现,被试在记叙文阅读过程中使用的阅读策略种类数和总次数均多于说明文。阅读材料难度对于阅读策略种类数和使用次数没有影响。阅读材料类型和难度都对多个阅读策略的使用次数有影响,但是阅读材料类型和难度对于各阅读策略使用次数的影响并不一致。 相似文献

使用被试间实验设计,分别研究了个体和团体两种不同的任务情境中,心理卷入强度高低对决策效果的影响。结果表明:(1)无论个体还是团体任务情境,不同的心理卷入度的决策者,决策结果差异显著;高心理卷入情境下,决策者的决策更为客观和公平。(2)团体任务高心理卷入情境下,学生对自己小组的评价和对其他小组的评价差异不显著。(3)团体任务情境中成员的决策结果比个体任务情境的更为客观。 相似文献

The author used role theory, continuity theory, and the life course perspective to form hypotheses regarding the different retirement transition and adjustment patterns and how different individual and contextual variables related to those patterns. The longitudinal data of 2 samples (n(1) = 994; n(2) = 1,066) from the Health and Retirement Survey were used. Three latent growth curve patterns of retirees' psychological well-being were identified as coexisting in the retiree samples through growth mixture modeling (GMM) analysis. On the basis of the latent class membership derived from GMM, retiree subgroups directly linked to different growth curve patterns were profiled with individual (e.g., bridge job status) and contextual variables (e.g., spouse working status). By recognizing the existence of multiple retiree subgroups corresponding to different psychological well-being change patterns, this study suggests that retirees do not follow a uniform adjustment pattern during the retirement process, which reconciles inconsistent previous findings. A resource perspective is further introduced to provide a more integrated theory for the current findings. The practical implications of this study are also discussed at both individual level and policy level. 相似文献

In 3 studies, the authors tested the hypothesis that Chinese participants would view social groups as more entitative than would Americans and, as a result, would be more likely to infer personality traits on the basis of group membership--that is, to stereotype. In Study 1, Chinese participants made stronger stereotypic trait inferences than Americans did on the basis of a target's membership in a fictitious group. Studies 2 and 3 showed that Chinese participants perceived diverse groups as more entitative and attributed more internally consistent dispositions to groups and their members. Guided by culturally based lay theories about the entitative nature of groups, Chinese participants may stereotype more readily than do Americans when group membership is available as a source of dispositional inference. 相似文献

Feature extraction via KPCA for classification of gait patterns 总被引:1,自引:0,他引:1
Automated recognition of gait pattern change is important in medical diagnostics as well as in the early identification of at-risk gait in the elderly. We evaluated the use of Kernel-based Principal Component Analysis (KPCA) to extract more gait features (i.e., to obtain more significant amounts of information about human movement) and thus to improve the classification of gait patterns. 3D gait data of 24 young and 24 elderly participants were acquired using an OPTOTRAK 3020 motion analysis system during normal walking, and a total of 36 gait spatio-temporal and kinematic variables were extracted from the recorded data. KPCA was used first for nonlinear feature extraction to then evaluate its effect on a subsequent classification in combination with learning algorithms such as support vector machines (SVMs). Cross-validation test results indicated that the proposed technique could allow spreading the information about the gait's kinematic structure into more nonlinear principal components, thus providing additional discriminatory information for the improvement of gait classification performance. The feature extraction ability of KPCA was affected slightly with different kernel functions as polynomial and radial basis function. The combination of KPCA and SVM could identify young-elderly gait patterns with 91% accuracy, resulting in a markedly improved performance compared to the combination of PCA and SVM. These results suggest that nonlinear feature extraction by KPCA improves the classification of young-elderly gait patterns, and holds considerable potential for future applications in direct dimensionality reduction and interpretation of multiple gait signals. 相似文献

An understanding of the differences in the ways in which self-efficacy and interest influence boys’ and girls’ intentions
to continue enrollment in mathematics courses may provide insight into how to encourage continued mathematics enrollment for
all students. Two competing theoretical models of mathematics self-efficacy and interest in predicting students’ enrollment
intentions and achievement were evaluated separately across samples of middle level boys and girls. One model was empirically
supported for both groups and indicated the independent influence of self-efficacy and interest in predicting enrollment intentions.
Multi-group analyses revealed that self-efficacy’s influence in enrollment intentions and achievement was significantly stronger
for boys than for girls, and interest was significantly more important in the prediction of enrollment intentions for girls
than for boys. 相似文献

通过三个实验研究了属性的中心性程度对归纳推理的影响,结果表明,在归纳推理中存在属性中心性效应,中心属性比其他属性(次中心属性、再次中心属性)更能影响归纳推理。但属性中心性效应的出现受到了前提对象和结论对象相似性程度的制约,当前提对象和结论对象的相似程度高时,中心属性比其他属性更能影响归纳推理;随着相似性水平的降低,中心属性的归纳推理力度越来越弱,而次中心属性、再次中心属性的归纳推理力度则会依次表现出越来越强的趋势,到最后当前提对象和结论对象的属性完全不相似时,最次中心属性的归纳推理力度达到最高水平,而中心属性的归纳推理力度则降低到最低水平。由于再次中心属性的归纳推理力度的最高水平没有显著高于随机水平,而中心属性的归纳推理力度的最低水平却显著低于随机水平,因此,研究者认为,在前提对象和结论对象完全不相似的情况下,被试将确信不能采用中心属性来进行归纳推理的力度判断,而采用猜测的方式选择了肯定可以排除的项目之外的其他项目,这体现了具有不确定的归纳推理活动的过程的典型特征 相似文献
