Asserting your mind: Interruptions extremize consumer choices

Interruptions prevail in the retail environment, especially during consumer decision-making. However, scant research has examined whether and how interruptions that suspend decisions affect consumer choices. We posit that interruptions heighten the consumers' preference certainty, which leads to a choice extremity effect—consumers choose their preferred products even more and their unpreferred products even less. Six experiments provide convergent evidence for the choice extremity effect and the underlying process. Study 1a shows that interruptions lead to choice extremity with a vice product (i.e., chips). Study 1b confirms the effect in the context of incentive-compatible choices. Study 2 replicates the choice extremity effect with a virtue product (i.e., yogurts). Study 3 further tests the robustness of the effect with a decision-related interruption. Study 4 shows that preference certainty mediates the effect of interruptions on choice extremity and rules out the level of arousal and task involvement as alternative accounts. Using a moderation approach, Study 5 shows that the choice extremity effect disappears when consumers have high self-concept clarity. The present study contributes to research on interruptions, preference certainty, and consumer choices and provides implications for marketers.     

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.     

Insights into computational thinking from think-aloud interviews: A systematic review

This systematic review examines 35 empirical studies featuring the use of think-aloud interviews in computational thinking (CT) research. Findings show that think-aloud interviews (1) are typically conducted in Computer Science classrooms and with K-12 students; (2) are usually combined with other exploratory CT assessment tools; (3) have the potential to benefit learners with special needs and identify the competency gaps through involving diverse participants; (4) are conducted in the absence of cognitive models and standard procedures; and (5) display insufficient definitional and methodological rigor. Theoretically, this review presents a systematic assessment about the application of think-aloud interviews in CT studies and identifies the limitations in existing CT-related think-aloud studies. Practically, this review serves as a reference for studying the cognitive processes during CT problem-solving and provides suggestions for CT researchers who intend to incorporate think-aloud interviews in their studies.     

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     

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。     

传统统计方法面临的挑战:元分析方法

利用计算机构造实验组和控制组总体,进行传统统计方法与元分析比较实验研究。在实验组总体高出控制组总体０．５０个标准差的提下,传统ｔ检验的统计检验能力（Ｐ）仅为为４１％;而利用元分析的方法进行统计分析,其结果与计算机构造模型有很高的一致性从而提出元分析方法在进入心理学实验研究和证实理论方面的有效性和可靠性,以及传统统计方法面临挑战的事实。     

Cultural orientation and psychological well-being in Chinese Americans

Examined cultural orientation in the domains of language proficiency, cultural activity, and social relationship, and its relationship with psychological well-being in a group of 143 Chinese Americans in San Francisco. Four indicators of psychological well-being were utilized, two assessing the experience of distress (depression level and negative affect) and two assessing positive well-being (positive affect and life satisfaction). Domain-specific cultural orientations were found to hold differential relationships with psychological well-being. For instance, bicultural activity orientation predicted the best psychological well-being (regardless as to how it was assessed), but socially separatist individuals experienced less negative affect than assimilated and bicultural respondents. Findings were discussed in the context of the multicultural setting of San Francisco. It is suggested that future research retain separate assessments of domain-specific cultural orientation, examine the contribution of the community's ethnic/cultural composition to its members' cultural orientations (i.e., address the role of person-environment fit) and study their impact on psychological well-being. The data reported here were collected as part of the author's doctoral dissertation. Ricardo F. Munoz and Guillermo Bernal guided and supported the implementation of this study; Sunwoo Lee assisted with the data analysis; and Edison J. Trickett and the anonymous reviewers offered helpful suggestions.     

与立体视觉相关的视诱发电位研究

在微机上编制能产生动态随机点立体图（ＤＲＤＳ）,亮暗类棋盘格和随机点背景三种图形刺激的软件．记录了３４例正常人在这三种刺激下的ＶＢＰ．其结果为：（１）ＤＲＤＳ刺激下的ＶＥＰＮ１波潜伏期为２６５±２５ｍｓ,基波能量占总交流能量的６３．２±１８．９％．（２）亮暗类棋盘格刺激下的ＶＥＰＮ１波的潜伏期为１９０±２２ｍｓ,基波能量占总交流能量的３９．２±１９．６％．（３）随机点背景刺激下的ＶＥＰ波则为一些杂乱的小波．结果提示：动态ＲＤＳ刺激下的ＶＥＰ除在潜伏期方面具有特异性外,并在谐波的能量分布上也具有特异性,且客观性更强．根据这些特征有助于对立体视觉功能进行客观性评价．     

年龄、作业难度和训练对成人记忆的影响

采用“联想学习”、“图象自由回忆”和“附加联想”三项目,对９０例成人（分为青年、老年和老老年组各３０例）进行记忆测查和训练,目的为探讨年龄,作业难度和训练对记忆的影响。结果表明：青年组记忆成绩明显高于老年和老老年组,后两组无显著差异;无关联想的年龄差异大于有关联想,作业难度扩大了年龄差异;各年龄组训练后记忆得到明显改善,并且训练扩大了年龄和作业易难的差异。由此可见,记忆受年龄、作业难度和训练三因素的相互作用,也再次证实了老年认知功能具有一定的可塑性。
