语言加工过程中的视听跨通道整合

日常生活中, 语言的使用往往出现在某个视觉情境里。大量认知科学研究表明, 视觉信息与语言信息加工模块并不是独立工作, 而是存在复杂的交互作用。本文以视觉信息对语言加工的影响为主线, 首先对视觉信息影响言语理解, 言语产生以及言语交流的相关研究进展进行了综述。其次, 重点对视觉信息影响语言加工的机制进行了探讨。最后介绍了关于视觉信息影响语言加工的计算模型, 并对未来的研究方向提出了展望。     

Does snobbish service generate better sales? The case of luxury goods

The objective of this study is to explore whether a “bad” service encounter triggers a consumer's impulse purchase in a luxury goods store in an Asian emerging market. A 2 (service encounter: favorable vs. snobbish) × 2 (shopping companion: alone vs. with a close friend) between‐group factorial design was employed with 160 female consumers in an Asian emerging market to examine the antecedents of both the urge to save social identity and the impulse purchase of luxury goods. The results show that consumers in an Asian emerging market can be triggered to make an impulse purchase of a luxury good, not because they received excellent service in the store but because they encountered snobbish service, especially when shopping with a close friend. Research implications and limitations are also discussed.     

The Bibimbap Migration Theory? Challenges of Korea’s Multicultural Mix and Social Integration Development

Migration was never a brand new phenomenon in South Korea, but its migration pattern has been redirected, migrant size has been amplified, and migrant ethnicity has been diversified in recent years. Korea is undergoing dramatic changes in its demographic composition with an increasing presence of foreigners since the 1990s. Traditionally known for its cultural uniqueness and ethnic homogeneousness, the ongoing inflow of foreigners has presented new challenges, as to who the Koreans are and how the modern Korean society should be defined. Some Koreans even raise concern over migration inflow as a threat to its nationhood purity. This research examines the shifting trend of immigration in Korea with a focus on the new social development of multiculturalism, while assessing the level of social integration and multicultural discourses of the public. In addition to those widely discussed marriage immigrants and foreign labor workers in the existing literature, the recent surge of professional expats, foreign teachers, and international students is becoming evident in Korea’s multicultural mix. Moreover, there is still a lack of literature on foreign migrants in Korea, including the US military service personnel, the foreign professional sports players, non-North Korean international refugees, and the latest, permanent residency immigrants through property investment in Korea. Despite the noted increasing inflow of a variety of immigrant residents, who are constantly shaping the new faces of Korea, the acceptance of ethnic diversity and cultural integration has yet to secure its solid place in the Korean society for multiculturalism to be truly embraced and flourished.     

Experimental Power for Indirect Effects in Group-randomized Studies with Group-level Mediators

Mediation analyses have provided a critical platform to assess the validity of theories of action across a wide range of disciplines. Despite widespread interest and development in these analyses, literature guiding the design of mediation studies has been largely unavailable. Like studies focused on the detection of a total or main effect, an important design consideration is the statistical power to detect indirect effects if they exist. Understanding the sensitivity to detect indirect effects is exceptionally important because it directly influences the scale of data collection and ultimately governs the types of evidence group-randomized studies can bring to bear on theories of action. However, unlike studies concerned with the detection of total effects, literature has not established power formulas for detecting multilevel indirect effects in group-randomized designs. In this study, we develop closed-form expressions to estimate the variance of and the power to detect indirect effects in group-randomized studies with a group-level mediator using two-level linear models (i.e., 2-2-1 mediation). The results suggest that when carefully planned, group-randomized designs may frequently be well positioned to detect mediation effects with typical sample sizes. The resulting power formulas are implemented in the R package PowerUpR and the PowerUp!-Mediator software (causalevaluation.org).     

家庭功能与流动青少年认同整合的关系:希望与父母文化持守的作用

本研究采取整群抽样的方法对来自广东省三所民办中学的1345名流动青少年进行问卷调查,探查流动青少年的家庭功能对其认同整合的影响,以及希望和父母文化持守在其中所起的作用。结果表明：（1）流动青少年的家庭功能正向预测了认同整合。（2）希望在流动青少年的家庭功能与其认同整合两者间起部分中介作用,家庭功能既对认同整合产生直接影响,也通过希望对认同整合产生间接影响;（3）流动青少年的父母文化持守调节了家庭功能与认同整合的关系。     

组织支持感对组织认同的影响:内部人身份感知和自尊的中介作用

检验了内部人身份感知(PIS)和基于组织的自尊(OBSE)在组织支持感(POS)对组织认同的影响过程中的角色和地位。采用多样本结构方程建模的方法,通过对中国2家企业的员工的问卷调查所获取的452份有效数据进行分析,结果表明:(1)POS对PIS和OBSE有直接的显著影响;(2)同时借助于PIS和OBSE的中介作用对组织认同产生间接的影响。     

加减法心算老化研究

以223名60～85岁老年人及30名大学生作为被试,对加减心算能力的老化过程进行研究。任务为加减法及加减法的组合,包括有：单加、单减、先加后减、先减后加、连加及连减。结果表明,年龄与心算类型存在明显的交互作用。单加及单减两种最基本的心算能力对其它类型心算成绩的作用,在不同年龄段表现不同：对于大学生,单加起主要影响作用,而对于老年人,单减起主要影响作用。     

关于自身记忆信念的年龄差异

记忆老化信念是元记忆研究的一个重要研究领域。本研究测量了94名老年人,38名年轻人记忆老化信念中关于自身记忆信念。结果发现,各年龄组间在对特定情境记忆能力信念上有差异,60～64岁、65～69岁年龄组被试对特定情境记忆能力评价最高,而70岁以上老年人与年轻组被试对特定情境上记忆能力评分无差异;年轻人对记忆的控制感要低于各组老年人;研究并没有发现被试在一般记忆能力信念上的年龄差异。     

人脑眶额皮质表征奖赏信息的进展

文章围绕人脑眶额皮质在表征奖赏信息上的核心作用展开,分别从人脑眶额皮质表征奖赏信息的共同神经表征和特异性神经表征特点,奖赏加工和该脑区局部形态特征之间的关系以及眶额皮质表征奖赏信息的时间动态性等角度对最近的重要研究进展进行了一定的梳理和概括。最后,文章讨论了未来研究需要解决的由奖赏类型多样性和脑区间奖赏信息整合复杂性带来的系列问题。     

不同程度隐私信息有意遗忘效应的实验研究

以三种不同水平的隐私信息为目标信息,模拟员工招聘情境,采用类似字表的研究范式,探讨了大学生被试对不同程度隐私信息的有意遗忘特点。结果发现：①在模拟员工招聘过程中,实验条件效应显著;②被试对高隐私信息的编码比低隐私信息编码更为精细;③在信息提取时,抑制只能对编码不精细的信息起作用,而对编码精细的信息无明显作用。④与个人有关的某些信息,特别是隐私信息在员工选择的决策中有负面的影响。
