Social factors influence solo and rat dyads exploration of an unfamiliar open field

Animal Cognition - Exploring new and unfamiliar environments is critical for survival, providing information on food, shelter, mates, and sources of danger. The open field paradigm is commonly used...     

The mood effect: How mood,disclosure language and ad skepticism influence the effectiveness of native advertising

This research investigated the interplay between mood, disclosure language, and ad skepticism on consumers' recognition and evaluation of native advertising. During two online experiments, participants first received a mood manipulation and then read an article-style native advertisement. Results from both studies indicated that participants were more likely to recognize a native ad with an explicit rather than an implicit disclosure label, and a negative mood was more likely than a positive mood to drive participants to recognize the native ad. More importantly, participants in a positive mood evaluated a native ad with an implicit disclosure more favorably than an ad with an explicit disclosure. By contrast, participants in a negative mood responded more positively to a native ad with explicit disclosure compared to an ad with implicit disclosure. Study 2 demonstrated that the interaction between mood and disclosure language was further moderated by individuals' levels of ad skepticism. These results are believed to provide meaningful theoretical and practical implications to the field of native advertising and consumer behavior.     

Divergent reactions to COVID-19 exhibited in grandiose and vulnerable narcissism

Grandiosity and vulnerability are distinct dimensions of narcissism that may exhibit differences regarding compliance with COVID-19 regulations and policies. Although both dimensions reflect entitlement and self-importance, motivational tendencies diverge. Narcissistic grandiosity reflects bold expressions consistent with approach motivation, whereas vulnerable narcissism reflects reactive expressions consistent with avoidance motivation. Therefore, the present cross-sectional investigation explored these relations between November 2020 and April 2021. Undergraduates (N = 487, M_age = 19.79, 87.1% women) completed online surveys that assessed grandiose and vulnerable narcissism, perceived severity of and susceptibility to COVID, attitudes and reactions toward COVID policies, as well as self-reported behavioral data including number of daily hours out in public, indoor bar/restaurant attendance, and whether they had ever received a positive COVID diagnosis. Consistent with theoretical distinctions between the two narcissistic dimensions, grandiosity generally predicted reduced behavioral compliance and extraverted tendencies that put them at risk for COVID exposure; however, both grandiosity and vulnerability predicted worse reactions and attitudes toward COVID-19 policies.     

狗对图形的同时辨別条件反射

巴甫洛夫学派大都是运用經典的先后对比的方法在狗身上建立条件反射分化的,用同时辨別的方法为数极少。英美学者則都应用同时辨別的方法研究动物对形状、大小、明度的辨別,但解释生理机制时只局限于感受部份,很少提及中枢作用。 早在1911年耶克斯-华生(Yerkes-Watson)創制了辨別箱,研究动物对图形的同时辨     

Pessimistic explanatory style and response to illness

Previous studies have shown that a pessimistic explanatory style is a risk factor for illness, but the factors linking explanatory style and illness are unknown. One's characteristic response to poor health may mediate this relationship. Perhaps pessimistic individuals act helplessly in the face of their symptoms, thereby exacerbating disease. In the present study, we investigated this possibility by asking 96 young adults to complete measures of explanatory style, habitual response to illness, and ways of coping during their most recent episode of illness. Subjects who explain bad events pessimistically (with internal, stable, and global causes) reported more frequent illnesses during the past year and rated their overall health more poorly than those who habitually favor external, unstable, and specific explanations. When ill, the pessimistic subjects were less likely than their optimistic counterparts to take active steps to combat their illness. Our results suggest that one pathway leading from pessimistic explanatory style to poor health is mundane: passivity in the face of disease.     

韦氏儿童智力量表中国修订本(WISC-CR)的因素分析

本研究用主成分分析和α因素分析两种方法对韦氏儿童智力量表中国修订本(WISC-CR)以及原量表WISC-R常模进行因素分析,并采用斜交旋转对初始因子矩阵进行转轴处理。结果表明:三因子模型比较符合WISC-CR的结构。常识、类同、词汇和理解四个分测验主要负荷言语理解因子;填图、图片排列、积木、拼图和迷津五个分测验主负荷知觉组织因子;而算术、背数和译码三个分测验主要负荷记忆/不分心因子。WISC-CR与WISC-R各分测验所负荷的各种因子一致性。83-.971,说明WISC-CR保持了原量表的功能,具有较好的结构效度。     

行为与脑的关系及其与机体其它属性间的相互作用的研究──心理学研究展望

“二十一世纪的心理学”的论题是当今许多科学家感兴趣的．这种预测是一种想象与现实相结合的尝试。审视过去和现在．心理学未来的雏形的基础可能是行为与脑的关系及其与生命其它属性之间的相互作用。     

自由回忆和线索回忆测验中的系列位置效应

本文以96个中国汉字为材料,使用自由回忆和线索回忆测验方法,对20名被试进行6组分测验和最后所有汉字的总测验。发现自由回忆分测验中存在明显的系列位置效应,总测验出现负近因现象;线索回忆分测验也表现出明显的系列位置效应,但最后的总测验没有出现负近因现象。上述结果验证了Bjork和Whitten（1974）提出的顺序或情景理论。     

婴儿共同注意能力的发展

本研究采用严格的实验室测验法,从年龄趋势、学习能力、性别差异三方面考察了8～11个月婴儿共同注意能力的发展。结果表明：1）婴儿的共同注意力在8～11个月间逐步提高,9个月左右出现显著的发展性变化,但1岁以前,该能力的发展水平都较低;2）就共同注意而言,婴儿具有从练习经验中学习的可能性,且学习能力存在年龄差异,8个月的婴儿基本不能从练习中受益,而8个月以上的其他三组婴儿在练习后共同注意水平都有不同程度的提高;3）总体而言,女婴共同注意能力的发展水平显著地高于男婴。     

中国颜色体系研究

概述了用颜色立体模型表示物体颜色,并做定量表示的颜色体系研究的理论意义及应用价值。介绍了国际上影响较大的颜色体系理论和编制原则的特点。中国颜色体系研究是在对国际上其它颜色体系的理论分析和对颜色样品测试的基础上,确立其理论依据和编制原则,开展了中国人眼对明度、色调、彩度等间距排列的视觉评价实验,建立了中国颜色体系理论模型。同时研制出《中国颜色体系样册》。该项研究于１９９３年７月通过了国家自然科学基金委员会和中国科学院联合召开的成果鉴定会,并得到良好的评价,又于１９９４年６月通过国家标准审查。该项研究的完成和推广,不仅能为我国国民经济各部门的颜色控制、标定和交流提供科学的颜色定量手段,同时也是对实用色度学的发展和颜色标准化工作做了有益的工作,产生了积极的经济效益和社会效益。
