To date, the notion of helpfulness of group processes has been equivocal in research on self-help groups. This article argues that findings drawn from the participants' subjective appraisals of helpfulness carry meanings different from those drawn from the correlational approach. In a mutual aid organization serving adults with mental health problems, the study found that, whereas universality, self-disclosure, and instillation of hope were the most valued processes, support and catharsis were the strongest correlates of benefits of participation. The authors propose a two-level hierarchy that distinguishes sustaining and beneficial factors. Different sets of factors should constitute the focus of facilitation at different stages of group development.  相似文献

The focus of cognitive diagnosis (CD) is on evaluating an examinee’s strengths and weaknesses in terms of cognitive skills learned and skills that need study. Current methods for fitting CD models (CDMs) work well for large-scale assessments, where the data of hundreds or thousands of examinees are available. However, the development of CD-based assessment tools that can be used in small-scale test settings, say, for monitoring the instruction and learning process at the classroom level has not kept up with the rapid pace at which research and development proceeded for large-scale assessments. The main reason is that the sample sizes of the small-scale test settings are simply too small to guarantee the reliable estimation of item parameters and examinees’ proficiency class membership. In this article, a general nonparametric classification (GNPC) method that allows for assigning examinees to the correct proficiency classes with a high rate when sample sizes are at the classroom level is proposed as an extension of the nonparametric classification (NPC) method (Chiu and Douglas in J Classif 30:225–250, 2013). The proposed method remedies the shortcomings of the NPC method and can accommodate any CDM. The theoretical justification and the empirical studies are presented based on the saturated general CDMs, supporting the legitimacy of using the GNPC method with any CDM. The results from the simulation studies and real data analysis show that the GNPC method outperforms the general CDMs when samples are small.  相似文献

The visual distinctiveness between targets and distractors can significantly facilitate performance in multiple object tracking (MOT), in which color is a feature that has been commonly used. However, the processing of color can be more than “visual.” Color is continuous in chromaticity, while it is commonly grouped into discrete categories (e.g., red, green). Evidence from color perception suggested that color categories may have a unique role in visual tasks independent of its chromatic appearance. Previous MOT studies have not examined the effect of chromatic and categorical distinctiveness on tracking separately. The current study aimed to reveal how chromatic (hue) and categorical distinctiveness of color between the targets and distractors affects tracking performance. With four experiments, we showed that tracking performance was largely facilitated by the increasing hue distance between the target set and the distractor set, suggesting that perceptual grouping was formed based on hue distinctiveness to aid tracking. However, we found no color categorical effect, because tracking performance was not significantly different when the targets and distractors were from the same or different categories. It was concluded that the chromatic distinctiveness of color overrides category in determining tracking performance, suggesting a dominant role of perceptual feature in MOT.  相似文献

唯物史观在《德意志意识形态》中创立之后,马克思在《资本论》及其手稿中通过对资本主义社会的科学批判使其得到运用与发展。马克思在《1861—1863年经济学手稿》中对斯密关于生产劳动社会规定性和物质规定性定义的批判,运用了唯物史观科学批判功能的历史辩证法引导出生产劳动的历史性生产关系线索,阐释了资本主义生产劳动的历史性;运用从抽象上升到具体的方法,在揭示出资本主义生产关系的实质之上,论证了资本主义生产劳动的本质特征。与此同时,唯物史观的价值批判功能表现出对资本主义生产劳动非人道性质的批判。马克思在《1861—1863年经济学手稿》中通过对斯密生产劳动理论的批判,创立了科学的生产劳动理论,丰富与发展了唯物史观关于资本主义生产劳动问题的研究。这对于我们理解新时代中国特色社会主义的生产劳动有一定的启发意义。  相似文献

The correlation between age and empathy is not clear, with prior findings yielding mixed and inconsistent results. Here, we distinguished between two aspects of empathy and respectively investigated the effects of age on the affective and cognitive facets of empathy using a self-report measure (interpersonal reactivity index, IRI) and performance-based tasks (viewing films). The results showed that older adults manifested age-related deficits in both trait and state cognitive empathy, with the latter being positively associated with memory. Otherwise, the overall affective empathy increased in the elderly, but the age-related differences in affective empathy may be qualified by the valence of the film clips. Specifically, older participants showed more empathic concern (EC) and less personal distress (PD) to other people’s emotions than the younger participants for the distress film. Interestingly, for the amusing film, older participants demonstrated more EC and PD. Overall, the two aspects of empathy have different development trajectories.  相似文献

This study aimed to examine the psychological status among Chronic Atrophic Gastritis (CAG) patients and to find the cumulative effects of risk and protective factors. A sample of 101 CAG patients completed the investigation. Hierarchical linear regression was used to find risk and protective factors, and examine the cumulative effects in risk factor index (RFI) and protective factor index (PFI). Results showed that nine symptoms from SCL-90-R were severer among CAG patients than those in adult norm. Risk factors including positive family history of cancer and higher negative life events could predict higher GSI (β = 0.206, p = 0.023; β = 0.398, p < 0.001; R² = 0.203); more household resistant, positive coping and stronger resilience were protective factors and could predict GSI negatively (β = -0.188, p = 0.020; β = -0.350, p = 0.012; β = ?0.066, p = 0.621; R² = 0.190). The GSI was positively correlated with RFI (β = 0.338, p < 0.001; R² = 0.113) and negatively related to PFI (β = ?0.378, p < 0.001; R² = 0.133). In conclusion, CAG patients suffered from various psychological distress, and the protective factors should be enhanced cumulatively to protect against psychological distress.  相似文献

海德格尔毕生的思想与上帝/神性难解难分。在后期重要著作《哲学论稿》中,海德格尔形成了对其后期思想具有规定作用的“存在/存有历史”观,以及以“本有”(Ereignis)为核心词语的后哲学之思。而在“存在/存有历史”思想的最后一个“关节”即“最后的上帝”一节中,海德格尔形成了与“本有”相关的神性之思,后者不同于传统神学——我们愿意称之为后神学的神思。  相似文献

风险社会中如何提升公众的政治信任成为焦点。以政治信任形成的终生学习理论为基础,将理性选择理论和社会文化理论相整合,探讨影响政治信任形成的因素,以及政治信任对政治合作的影响。对291名被试进行问卷调查,层次回归结果发现:政治信任在政治透明度感知、宽容度感知和政治合作之间发挥正向中介作用;在负面认知固化程度和政治合作之间发挥负向中介作用;政治氛围感知在政治信任和政治合作行为之间起调节作用。最后,对该结果形成的原因与在现实生活中的应用进行讨论,并对未来研究的发展方向进行展望。  相似文献
