情绪表达性对人际关系的影响概述

在日常生活中情绪表达性指:人们交流体验的影响和影响人际关系的方式、个体对表达内容、表达方式、表达对象的选择,决定了他人会作出怎样的反应,并将对个体的人际关系产生影响。良好的人际关系有利于大学生形成和发展健康的个性品质,也有利于培养他们的合作精神。本文主要介绍了情绪表达和人际关系的部分研究概述和研究所使用的工具,为以后的研究打下基础。     

Nudge to Health: Harnessing Decision Research to Promote Health Behavior

We review selected literature that examines how biases in decision making can be utilized to encourage individual health behavior, such as vaccination, and promote policy decisions, such as resource allocation. These studies use simple interventions to nudge people towards more optimal health decisions without restricting decision‐makers’ freedom of choice. Examples include framing effects, defaults, implementation intentions, position effects, social norm, incentives, and emotions. We suggest that nudges are an effective way to promote healthy behavior.     

The dimensionality of coping among Chinese health care workers

The transactional model defines coping as a process that changes on the basis of the context of an environmental encounter. An instrument used to investigate coping in diverse person-environment interactions is the Ways of Coping Questionnaire (WOC; S. Folkman & R. S. Lazarus, 1988). Although evidence exists to support the basic underlying structure of the WOC in Western societies, no research has been conducted on the instrument's dimensionality in non-Western societies. The authors identified 14 factors for the WOC administered to a sample of health care workers in Beijing, China. The 14 factors identified in the present study were similar to the 8 factors identified in the original validation study (S. Folkman, R. S. Lazarus, C. Dunkel-Schetter, A. DeLongis, & R. J. Gruen, 1986), but they were more content specific.     

Impairment of spatial learning and hippocampal synaptic potentiation in c-kit mutant rats

The c-kit receptor tyrosine kinase encoded by the white-spotting (W) gene is highly expressed in rat hippocampal CA1–CA4 regions. We found an impaired spatial learning and memory in homozygous c-kit (Ws/Ws) mutant rats that have a 12-base deletion in the tyrosine kinase domain of the c-kit gene and a very low kinase activity. Electrophysiological studies in hippocampal slices revealed that the long-term potentiation (LTP) induced by the tetanic stimulation (100 Hz, 1 sec) in the mossy fiber (MF)–CA3 pathway, but not in the Schaffer collaterals/commissural–CA1 pathway, was significantly reduced in c-kit mutants compared with wild-type (+/+) rats. The paired-pulse facilitation (PPF) was measured before the tetanus and after the establishment of the LTP in each slice. The initial PPF in the MF–CA3 pathway positively correlated with the amplitude of the LTP in the wild-type rats but not in the c-kit mutant rats. Furthermore, they failed to show the normal characteristics observed in the MF–CA3 pathway of +/+ rats; that is, the negative correlation between the initial PPF and the changes in PPF measured after the LTP. These findings suggest an involvement of SCF/c-kit signaling in hippocampal synaptic potentiation and spatial learning and memory.     

The differential effects of thalamus and basal ganglia on facial emotion recognition

This study examined if subcortical stroke was associated with impaired facial emotion recognition. Furthermore, the lateralization of the impairment and the differential profiles of facial emotion recognition deficits with localized thalamic or basal ganglia damage were also studied. Thirty-eight patients with subcortical strokes and 19 matched normal controls volunteered to participate. The participants were individually presented with morphed photographs of facial emotion expressions over multiple trials. They were requested to classify each of these morphed photographs according to Ekman's six basic emotion categories. The findings indicated that the clinical participants had impaired facial emotion recognition, though no clear lateralization pattern of impairment was observed. The patients with localized thalamic damage performed significantly worse in recognizing sadness than the controls. Longitudinal studies on patients with subcortical brain damage should be conducted to examine how cognitive reorganization post-stroke would affect emotion recognition.

Using the open-source statistical language R to analyze the dichotomous Rasch model

R, an open-source statistical language and data analysis tool, is gaining popularity among psychologists currently teaching statistics. R is especially suitable for teaching advanced topics, such as fitting the dichotomous Rasch model-a topic that involves transforming complicated mathematical formulas into statistical computations. This article describes R’s use as a teaching tool and a data analysis software program in the analysis of the Rasch model in item response theory. It also explains the theory behind, as well as an educator’s goals for, fitting the Rasch model with joint maximum likelihood estimation. This article also summarizes the R syntax for parameter estimation and the calculation of fit statistics. The results produced by R is compared with the results obtained from MINI STEP and the output of a conditional logit model. The use of R is encouraged because it is free, supported by a network of peer researchers, and covers both basic and advanced topics in statistics frequently used by psychologists.     

Learning as a task or a virtue: U.S. And Chinese preschoolers explain learning

The purpose of this study was to examine cultural influences on conceptual orientations of learning in U.S. and Chinese preschoolers. A sample of 188 preschoolers 4-6 years of age provided free-narrative responses to 2 story beginnings about the learning behavior of 2 protagonists, 1 who worked hard and 1 who gave up. Results showed that despite some differences in the younger age groups, children from both cultures valued learning similarly at age 6. However, important cultural differences emerged in children's construals of the learning process. U.S. children showed a heightened awareness of the mind/task attributes of the learner, that is, ability, task attempting, and strategy use. By contrast, Chinese children perceived more the learner's dispositional qualities of diligence, persistence, and concentration. These trends increased as children's age increased. The U.S. findings are interpreted as reflecting the U.S. cultural emphasis on learning as a task, and the Chinese results, as reflecting the Chinese cultural focus on learning as a process of cultivating personal virtue.     

Stability and variability may respond differently to changes in walking speed

In gait research it has often been assumed that variability and stability are negatively correlated, where increases in variability are assumed to equate with increases in instability. The purpose of this paper is to illustrate that variability does not always equate with stability. To proof this point, a method was developed to directly assess stability and variability during the application of a visual perturbation at different walking speeds. Walking variability was measured by using the average standard deviation of the knee joint angle across the gait cycle. Walking stability was measured by the recovery time of the knee joint angle trajectory from the distortion induced by a visual perturbation that was delivered at the beginning of the stance phase. Five participants were required to walk at six different velocities on a treadmill (0.67, 0.80, 0.94, 1.07, 1.21, and 1.34 m/s). The coefficients of intraclass correlations for the experiment were 83% and 80% for the calculated stability and variability, respectively. The calculated stabilities were not sensitive to changes in walking speed (p>0.98). The calculated variability however decreased with increases in walking speed (p=0.004). No significant correlation between variability and stability was observed (r=-0.002). We suggest that gait stability is independent of variability during locomotion and should thus be measured independently.
