Age differences in the likelihood of destructive anger responses under different relationship contexts: a comparison of mainland and Hong Kong Chinese

This brief report examined how the likelihood of destructive anger responses varied with age across relationship contexts. Seventy-six older adults and 100 younger adults from Hong Kong and Mainland China reported their responses to anger-eliciting scenarios elicited by a kin, a close or a casual friend. Results indicated that compared with their younger counterparts, older Hong Kong Chinese were less likely to report direct aggression toward kin, but older Mainland Chinese were more likely to do so. Older Hong Kong Chinese were less likely to report malevolent and fractious motives than were younger Chinese across all relationships; Older Mainland Chinese were less likely to do so only in friendship. Findings have implications for conceptualizing age-related emotion regulation across relationships and cultures.     

Cathodal transcranial direct current stimulation of the right Wernicke's area improves comprehension in subacute stroke patients

Previous studies have shown the appearance of right-sided language-related brain activity in right-handed patients after a stroke. Non-invasive brain stimulation such as transcranial direct current stimulation (tDCS) and repetitive transcranial magnetic stimulation (rTMS) have been shown to modulate excitability in the brain. Moreover, rTMS and tDCS have been found to improve naming in non-fluent post-stroke aphasic patients. Here, we investigated the effect of tDCS on the comprehension of aphasic patients with subacute stroke. We hypothesized that tDCS applied to the left superior temporal gyrus (Wernicke’s area) or the right Wernicke’s area might be associated with recovery of comprehension ability in aphasic patients with subacute stroke. Participants included right-handed subacute stroke patients with global aphasia due to ischemic infarct of the left M1 or M2 middle cerebral artery. Patients were randomly divided into three groups: patients who received anodal tDCS applied to the left superior temporal gyrus, patients who received cathodal tDCS applied to the right superior temporal gyrus, and patients who received sham tDCS. All patients received conventional speech and language therapy during each period of tDCS application. The Korean-Western Aphasia Battery (K-WAB) was used to assess all patients before and after tDCS sessions. After intervention, all patients had significant improvements in aphasia quotients, spontaneous speech, and auditory verbal comprehension. However, auditory verbal comprehension improved significantly more in patients treated with a cathode, as compared to patients in the other groups. These results are consistent with the role of Wernicke’s area in language comprehension and the therapeutic effect that cathodal tDCS has on aphasia patients with subacute stroke, suggesting that tDCS may be an adjuvant treatment approach for aphasia rehabilitation therapy in patients in an early stage of stroke.     

小学生数学应用题解题水平影响因素的实验研究

该研究采用四因素混合实验设计考察不同的问题呈现方式对不同视空间能力、场认知方式以及不同年级小学生的数学应用题解题水平的影响情况,研究得出以下结论:有一定视觉提示的问题呈现方式在不同程度上促进了小学生数学应用题解题水平的提高,但不同的问题呈现方式对不同被试影响情况不同;低空间能力-场依存型被试在图形提示的呈现方式下解题水平提高程度最大。

Low self‐esteem,entrapment, and reason for living: A moderated mediation model of suicidal ideation

Adolescent suicidal ideation has become a top public health concern. It is thus significant to explore both risk and protective factors of adolescent suicidal ideation. The present study tested a moderated mediation model of suicidal ideation in a sample of Chinese adolescents. Chinese adolescents of 1074 (54.2% females, aged between 11 and 18 years) completed questionnaires assessing self‐esteem, entrapment, reason for living, and suicidal ideation. We found that entrapment mediated the association between low self‐esteem and suicidal ideation. The association between entrapment and suicidal ideation was moderated by reason for living. Findings of this study may expand our understanding of the development of suicidal ideation, and facilitate future research exploring the interplay of risk and protective factors of suicidality. Clinical implications of these findings were also discussed.     

绿色生活方式的结构与测量

基于前人研究,结合对241份访谈问卷进行内容分析,构建绿色生活方式由知、情、意、行四维度组成的理论假设,并依照该理论初步编制绿色生活方式量表。采用调查法回收有效问卷1051份,结果显示:量表的 Cronbach α系数为0.919,分半信度系数为0.876,0.868; 量表与各维度均存在显著的中高等相关,各维度间存在显著的中低等相关; 探索性因素分析的结果与理论构想基本一致,验证性因素分析结果表明模型拟合度良好; 此外,量表能较好区分环境态度与环保行为有不一致倾向的个体。因此,本研究制定的绿色生活方式量表具有较好的信效度,并可为区分“言行一致”或“言行不一”的个体提供一定参考。

The Job Demands-Resources Model and Job Burnout: The Mediating Role of Personal Resources

The primary purpose of this study is to test whether the effect of workload on emotional exhaustion (health impairment process) and social support on depersonalization (motivation process) could be mediated by personal resources such as self-efficacy, self-esteem and optimism. Two multiple mediation models are tested separately, and then the point estimate and bias-corrected and accelerated 95 % confidence interval of the total and specific indirect effect are determined using the bootstrap approach with 1000 bootstrapped samples. The results show that workload positively affects emotional exhaustion, whereas social support negatively affects depersonalization, thus further corroborating the health impairment process and motivation process as assumed by the job demands-resources (JD-R) model. The total indirect effect is significant for both models, and self-esteem and optimism are the significant mediators for the health impairment process, whereas only optimism is the significant mediator for the motivation process.
