社交媒体信任对重大突发公共卫生事件中公众网络谣言自治行为的影响

从社会心理学视角、以社交媒体信任为切入点,基于新冠肺炎疫情,考察公众在重大突发公共卫生事件中网络谣言自治行为的心理机制。采用问卷方法对963名成年居民进行调查。结果表明:(1)公众对官方社交媒体的信任既能直接促进公众的辟谣行为,也能通过增强公众对战胜疫情的信心产生间接影响;(2)公众对官方社交媒体的信任影响公众对自媒体的信任,但自媒体信任不能独立于官媒信任影响辟谣行为。因此,我国社交媒体存在着两个舆论场且官方舆论占主导地位,及时、有效的官方报道不仅能提高公众对战胜疫情的信心,也能促进公众网络谣言自治,进而实现网络谣言治理主体的多元化。     

The lexical constituency model: some implications of research on Chinese for general theories of reading

The authors examine the implications of research on Chinese for theories of reading and propose the lexical constituency model as a general framework for word reading across writing systems. Word identities are defined by 3 interlinked constituents (orthographic, phonological, and semantic). The implemented model simulates the time course of graphic, phonological, and semantic priming effects, including immediate graphic facilitation followed by graphic inhibition with simultaneous phonological facilitation, a pattern unique to the Chinese writing system. Pseudocharacter primes produced only facilitation, supporting the model's assumption that lexical thresholds determine phonological and semantic, but not graphic, effects. More generally, both universal reading processes and writing system constraints exist. Although phonology is universal, its activation process depends on how the writing system structures graphic units.     

ERP evidence for the time course of graphic, phonological, and semantic information in Chinese meaning and pronunciation decisions

Two words that varied in their relationship were presented sequentially to Chinese readers who made meaning and pronunciation decisions. In the meaning task, they decided whether the words had the same meaning. In the pronunciation task, they decided whether the words had the same pronunciation. In both tasks, the word pairs represented 1 of 4 relationships: graphically similar, homophonic, semantically related, or unrelated. Event related potentials (ERP) recordings made from the onset of the 2nd word suggested a temporal unfolding of graphic, phonological, and semantic effects. Specifically, graphically-related pairs produced a smaller P200 in the pronunciation task and a smaller N400 in the meaning task. Homophones produced reduced N400 component with bilateral sources in the meaning task.     

论人对自然的权利和义务

人对自然的权利和义务是相辅相成、紧密联系的。人类在享有对自然的权利的同时,应该也必须履行对自然的相应义务。人对自然的权利和义务主要包括三方面的内容:其一,人类享有在适宜的自然环境中生存的权利,同时负有保护和改善自然环境的义务;其二,人类享有在适宜的自然环境中发展的权利,同时负有可持续发展的义务;其三,人类享有利用自然资源的权利,同时负有保障自然资源合理开发利用的义务。人对自然的权利和义务问题的实质是利益问题。     

母亲积极养育行为对儿童顺从行为的早期预测与双向作用:从婴儿到学步儿

顺从是儿童早期重要的社会化成就。传统理论关注父母控制策略对顺从的作用,但实证结果表明其解释率有限;当前理论更加关注积极养育行为在顺从发展中具有发展适宜性的作用机制。本研究采用追踪设计考察了84个家庭从儿童6个月到3岁时母亲的敏感性和鼓励自主两种积极养育行为与学步儿顺从发展的关系。结果表明:(1)1岁前母亲敏感性对学步儿2岁时的合作性顺从有正向预测作用,对2岁到3岁合作性顺从的变化没有预测作用;(2)1岁前母亲敏感性对学步儿2岁时的情境性顺从和2岁到3岁的情境性顺从的变化均有负向预测作用;(3)在2岁到3岁期间,母亲的鼓励自主与学步儿的合作性顺从水平有双向正向预测作用,但与情境性顺从不存在双向预测关系。     

句子语境中汉语词汇识别的即时加工过程

视觉词汇的认知加工及语境对这一过程的影响是心理语言学和认知心理学研究的热点。本研究采用眼动方法与ERP技术相结合的手段,考察了句子语境中汉语词汇识别的加工过程。通过六个实验, 探讨了不同限制性语境中汉语词汇形、音的作用及作用的脑机制, 不同偏向性语境对词汇歧义消解的影响及词汇歧义消解的脑机制。该研究结果揭示了句子语境对汉语词汇识别的影响, 提供了眼动方法和ERP技术相结合考察语言认知的研究范例。     

Burger or yogurt? Indulgent consumption in impression management contexts

We conducted three studies to investigate indulgent choice in settings with and without impression management by public–private manipulation with evaluation. Study 1 showed that the participants were less indulgent under public scrutiny due to the employment of impression management. Study 2 focused on the impression management context to test the moderate effect of self‐consciousness in two impression managed contexts. Study 3 focused on context without impression management to test the moderate effects of self‐awareness on choices. We found that depending on differences in primed personality, individuals tended to make choices other than those they favoured privately when anticipating that others might form impressions of them based on the decisions made. The findings of all three studies support our basic prediction that people are less indulgent under impression management and suggest that people tend to manage their impression by eating healthier (less indulgently) in public.     

考试焦虑者注意偏向的认知与神经机制

应用情绪版本的外部线索任务,以高中生为研究对象,探讨考试焦虑的产生是由负性刺激的警觉还是脱离困难导致的认知神经机制,以及这种注意偏向(警觉与脱离成分)发生的具体时间进程。行为实验结果发现,相比起低考试焦虑个体,高考试焦虑个体对考试相关威胁刺激存在注意脱离困难。脑电实验结果中,P1成分揭示高考试焦虑者对考试相关和无关威胁线索后靶刺激的注意处理削弱;考试相关威胁线索后靶刺激诱发的P300对于高、低考试焦虑者具有临床鉴别的潜力。     

亲社会自主动机对青少年幸福感及亲社会行为的影响:基本心理需要满足的中介作用

本研究探讨了亲社会自主动机对青少年幸福感和亲社会行为的影响,并检验了基本心理需要满足的中介作用。研究1以293名青少年为研究对象,通过问卷法考察了亲社会自主动机、基本心理需要满足、幸福感和亲社会行为的关系;研究2以205名青少年为研究对象,通过实验法操纵亲社会自主动机（vs.受控动机）,并考察其对基本心理需要满足、幸福感和亲社会行为的影响。研究结果表明,亲社会自主动机显著正向预测青少年的幸福感和亲社会行为,并且基本心理需要满足在亲社会自主动机对幸福感和亲社会行为的预测中都起到了中介作用;相反,亲社会受控动机则不利于青少年基本心理需要的满足,进而不能有效地提升其幸福感和亲社会行为。     

The impact of associative strength on performance in goal pursuit

The present research explored the hypothesis that strengthened attainment means–goal association leads to enhanced performance in goal pursuit. We hypothesize that because of the instrumental nature of means–goal association, strengthened associative strength leads to greater instrumentality expectancy of the means, which elicits greater motivation in the pursuit and hence better actual performance. We demonstrated in four studies that when the means is believed to facilitate goal attainment, a strong (vs. weak) means–goal association leads to greater performance in goal pursuit. Conversely, when the means is perceived to undermine goal attainment, a strong (vs. weak) association results in worse performance in goal pursuit.
