苏联心理学界对活动理论的近期讨论

本文综述了近几年来苏联心理学界对A.H.列昂节夫代表的活动理论的讨论情况。其中包括三种意见,一种是支持态度,一种是持较大异议、企图用系统论取而代之的态度,一种是既不完全支持,也不完全否定的态度。从讨论中可以看出,活动理论在苏联仍有很大影响,人们公认列昂节夫是苏联马克思主义心理学奠基者之一,公认他提出的活动理论对建设马克思主义心理学的重要贡献。目前开展的讨论,不是要否定和批判活动理论,而是在爱护、珍惜它的前提下,对它进行补充、修正和发展,使它更加完善。作者认为,这一讨论对我们的主要启示是:一、苏联心理学者在把马克思主义作为建设心理学的方法论基础这一点上,没有根本分歧;二、我国心理学界需要展开一些理论上的争鸣和讨论,需要培养我们自己的理论家;三、必须首先明确“中国心理学的发展究竟走哪条路”的问题,为此应该重视基本理论的建设。     

Factors influencing readability of rapidly presented text segments

Experiment 1 compared paragraph comprehension for texts shown either as normal pages on a computer terminal screen or as rapid serial visual presentations (RSVPs) of small text segments to a common location. Over several days of practice, reading comprehension was equivalent in the normal presentation mode and the RSVP format. When successive RSVP segments contained some information in common, to mimic the experience of successive parafoveal and foveal views of words in normal reading, comprehension was somewhat worse than when successive segments contained no overlapping information. Experiment 2 used a variety of segment size and segment duration combinations to investigate the optimal means of presenting text in the RSVP format. Across a variety of presentation rates and text difficulties, comprehension was maximal for segments averaging about 12 character spaces in length. In Experiment 3, texts were divided into short idea units or into random segments of equal average length. Comprehension was shown to be greater in the structured condition than in the random condition. An optimal means of presenting text in the RSVP format could be superior to normal presentation methods for reading and other text-processing tasks.     

刺激-效应的统一模型

本文通过对某些神经生理学实验结果的分析,从人体感受器官能够经受信号强度的巨大变化出发,建立了反映刺激τ和效应E一般关系的效应方程E=Blog(1+τ)。式中系数B为与效应E同量纲或性质的条件恒量。 值得注意的是,效应方程把心理学领域中许多不相关的经验定律用统一的模型联系起来。例如,从效应方程出发,能够推出实验心理学中的遗忘定律、海曼公式,心理物理学中的费希纳定律、韦伯定律、费瑞—帕特定律和格拉涅-哈帕公式等。 此外,对遗忘定律进行了修正,使其能适用于0≤t<1的时间范围,从而变得较全面。对费希纳定律也作了类似的修正,避免了出现负的感觉,并从不同角度阐述了效应E与感觉S的某些性质。对格拉涅-哈帕公式则作了较前更为合理的解释。 在推导关于闪光融合频率的费瑞-帕特定律时,得出一条影响中枢神经处理信息的速度和精度的规律。 作为这一模型的直接验证,可以从前人所作的一些实验数据分析中得出。本文举的例子为鲎鱼单根神经的实验;在另文里将举出反应时间依赖于刺激强度的另一个实例。     

两例先天性无痛症患者的心理生理特点研究 Ⅰ.情绪特点

本工作研究两例先天性无痛症患者的心理特点,主要是其情绪特点,以探讨疼痛和情绪的关系,并借以检验疼痛学说的意义。例一,女,10岁,智力略低于正常,艾森克少年儿童人格问卷表评定人格正常。与身体损伤有关的恐惧感明显缺乏,但与社会和教育影响有联系的恐惧感却甚于正常儿童。情绪急躁,易发作暴发性脾气而不能控制。在突然刺激(强光、强铃声)下的反应和正常儿童相近。例二,男,13岁,智力明显落后,人格评定正常,各种恐惧感均明显缺乏。情绪经常呈明显欣快状态。突然刺激下有口语惊吓和动作反应但无相应的面部表情和植物性神经系统的变化。两例均有无目的的多动作表现。看来疼痛和情绪有某种关系,但本结果并不能证实疼痛的情绪学说。     

How solitude relates to well-being in old age: A review of inter-individual differences

Older adults are more likely to live alone and engage in solitary activities than young adults, leading to decrement in their well-being. However, researchers have discovered beneficial implications of solitude, and some of them even have established that the negative and positive effects of solitude coexist. The study's purposes are to investigate the relationship between solitude and well-being among older adults and to further examine the inter-individual differences in this relationship. In the database of Google Scholar, the systematic review methods are used and 17 articles meet the inclusion criteria. The study concludes that older adults experience solitude both negatively and positively; the complex relationship between solitude and well-being can be better understood and explained by inter-individual differences based on intrapersonal, interpersonal, and cultural factors. This systematic review adopts a perspective that spans individual and social/cultural levels and helps grasp the link between solitude and well-being in older adults. Based on this review, the researcher can develop appropriate interventions to help older people maximize the benefits of solitude while minimizing the drawbacks to further achieve a higher quality of life.     

Does authenticity always breed mental health? A cross-cultural comparison between the United States and China

Numerous studies on Western cultures have suggested a strong linkage between authenticity and mental health. However, little is known about whether such an association can be generalized to Eastern cultures. This study aimed to conduct a cross-cultural comparison on the association between three dimensions of authenticity (authentic living, self-alienation, and accepting external influence) and two factors of mental health (negative and positive) across Western and Eastern cultures. Measurement invariance tests were carried out and multigroup structural regression models developed on two college samples from the US (n = 392) and China (n = 281). Results suggested that the associations between authenticity and the negative factor of mental health were consistent across cultures, where both self-alienation and accepting external influence were positively associated with anxiety. However, the associations between authenticity and the positive factor of mental health were different in the US and Chinese samples. Specifically, both authentic living and accepting external influence were significantly associated with life satisfaction in the US sample but not in the Chinese sample. Findings stress that having a nondistorted perception of the true self is critically related to lower levels of anxiety across cultures and highlighted the need to identify culture-specific promotive factors for life satisfaction.     

Fragile promise: The role of justification in promise-breaking

People who consider themselves moral sometimes use self-serving justifications to rationalize their selfish behaviours. Previous studies have tested the role of ambiguity in justifying wrongdoings, but it remains unclear whether ambiguity also plays a role in justifying promise-breaking behaviour and whether heterogeneity exists. To investigate justification in promise-breaking, we introduced a new experimental paradigm called the card-guessing task and used hierarchical cluster analysis to classify participants based on their promise-breaking decisions in unambiguous and ambiguous conditions. Experiment 1 revealed three clusters of solutions: Cluster 1 always kept their promises (i.e., keepers); Cluster 2 only exploited the vague promises and broke their promises in the ambiguous condition (i.e., intermediates); Cluster 3 tended to take advantage of vague promises and broke their promises irrespective of ambiguity (i.e., breakers). Experiment 2 confirmed that participants in the three clusters differed in their norm-abiding preferences and social value orientations. Keepers were more altruistic and had a stronger sense of norm compliance than intermediates and breakers. In conclusion, our study demonstrates that self-serving justifications were more likely to be employed by people who are moderately sensitive to deviation from social norms, which has implications for strategic interventions and policy formulation concerning unethical behaviour.     

Worldviews about change: Their structure and their implications for understanding responses to sustainability,technology, and political change

People hold different perspectives about how they think the world is changing or should change. We examined five of these “worldviews” about change: Progress, Golden Age, Endless Cycle, Maintenance, and Balance. In Studies 1–4 (total N = 2733) we established reliable measures of each change worldview, and showed how these help explain when people will support or oppose social change in contexts spanning sustainability, technological innovations, and political elections. In mapping out these relationships we identify how the importance of different change worldviews varies across contexts, with Balance most critical for understanding support for sustainability, Progress/Golden Age important for understanding responses to innovations, and Golden Age uniquely important for preferring Trump/Republicans in the 2016 US election. These relationships were independent of prominent individual differences (e.g., values, political orientation for elections) or context-specific factors (e.g., self-reported innovativeness for responses to innovations). Study 5 (N = 2140) examined generalizability in 10 countries/regions spanning five continents, establishing that these worldviews exhibited metric invariance, but with country/region differences in how change worldviews were related to support for sustainability. These findings show that change worldviews can act as a general “lens” people use to help determine whether to support or oppose social change.     

Inspired to donate: How donors' social class impacts charitable donations

Previous research has found that donors' social class affects their own charitable giving. This research explores the effect of donors' social class on others' donation behavior. Specifically, we propose that individuals feel more inspired to engage in prosocial behavior after learning about low-social-class donors (vs. high-social-class donors) perform the giving behavior. A series of five studies, combining online and experimental data, provide converging support for this proposition and its underlying mechanism of inspiration. Furthermore, we show that the effect of donors' social class on individuals' donation behavior is attenuated when the donation currency is goods (instead of money). The article concludes with implications for the marketing of charities and prosocial behaviors.
