两类常见的类别变量调节效应分析

类别变量在心理学和其他社科研究领域经常遇到,当自变量或调节变量为类别变量时,应当如何分析调节效应呢？详述了多类别变量的被试间设计和两水平被试内设计（因变量重复测量2次）的调节效应分析方法,并给出了分析流程。先进行调节效应的显著性检验,后用选点法或Johnson-Neyman法进行简单斜率检验。多类别变量被试间设计的简单斜率检验是先进行整体检验,后进行配对检验。用两个实际例子演示如何进行类别变量的调节效应分析,最后展望了两类设计的类别变量的调节研究的拓展方向,例如更复杂的类别变量的调节模型等。

听觉词源记忆与再认记忆的差异性研究

该项研究探讨被试对听觉词源检测和再认的差异性,并比较了男女被试的源检测和再认情况.实验以两字汉字词为记忆材料,设计了三个因素.性别因素指男女被试性别水平;声源因素设计了男性和女性两种声源呈现听觉词,为组内设计;学习因素为两个水平的组内设计,水平一是偶然学习,水平二是重复学习,也为组内设计,该因素考查学习效应.研究分别统计两种声源词的再认和源检测成绩,结果分析显示:被试源检测的学习效应显著,而再认的学习效应不显著;两种声源词的源检测差异显著,而再认的差异不显著;同类测试之间存在显著相关,两种测试之间相关不显著;偶然学习条件下,男女被试对男性声源词的源检测差异显著.研究结果提示,源检测的内部认知过程不同于再认,并且两种性别人群的源记忆可能存在某些方面的差异.     

专业背景、主观印象和情绪对量刑决策的影响

为了考察司法决策者对案件当事人的主观印象如何影响刑罚决策及情绪在其中的作用,本研究要求法律与非法律专业被试对案情相同但对案件当事人的主观印象不同的刑事案件进行刑罚强度决策,并要求被试对犯罪行为所引发的情绪强度进行评定。研究结果发现,被试对施害人的消极印象比积极印象条件下产生更强的愤怒和厌恶情绪,更少的同情情绪,同时,给予的刑罚更重;被试对受害人的积极印象比消极印象条件下,低年级组被试对施害人给予的刑罚更重,但在高年级组被试中不存在显著差异,两组被试在情绪强度上也没有显著差异。法律专业比非法律专业被试对犯罪行为所产生的情绪强度更低。被试的专业背景对量刑决策没有显著影响。中介效应检验发现,在施害人的主观印象对刑罚决策的影响过程中,愤怒和同情表现出部分中介效应,厌恶情绪表现出完全中介效应。     

网络语言文案对广告注意和感知的影响

网络语言作为广告文案经常被应用于营销实践中,但少有文献探讨此类应用对于传播效果的影响。本研究采用大学生被试,基于信号理论和情感迁移理论来分析网络语言文案如何影响消费者对于广告的注意和感知。研究1通过眼动实验考察网络语言广告文案对被试注意的影响。结果显示,相较于标准语言,网络语言广告文案吸引了受众更多的注意,但在广告观看时间有限的情况下,会减少受众对于广告图片的注意。研究2采用问卷方法考察网络语言文案对广告信任和产品评价的影响及其中介效应。结果显示,网络语言文案会提升消费者对于广告产品的评价,这一效应受到受众的感知广告有趣性的部分中介。另外,网络语言文案会降低消费者的广告信任,这一效应受到受众的感知广告严谨性的完全中介。本文还讨论了研究结果对于学术理论和营销实践的意义。

常见的类别变量的有调节的中介模型分析

社科研究领域常用到类别变量的中介和调节效应分析。如果中介和调节整合在一起,当自变量或调节变量为类别变量时,应当如何进行有调节的中介效应分析呢？以两阶段被调节的中介模型为例,详述了类别自变量或类别调节变量的有调节的中介效应分析的方法,接着用实际例子演示如何进行分析,并给出了相应的Mplus程序。最后展望了未来的拓展方向,包括模型拓展、变量拓展（二分因变量）和类别变量的编码拓展。     

大学生的观点采择与助人行为:群体关系与共情反应的不同作用

以56名大学生为被试,采用被试内设计先后在群体内外两种条件下完成观点采择、共情反应与助人行为实验,探讨大学生观点采择在影响其助人行为的过程中,群体关系与共情反应的不同作用。结果表明:(1)在内外群体关系中,大学生观点采择对助人行为的影响均需要借助于共情反应的中介而发挥作用;(2)群体关系在观点采择对助人行为的作用中发挥了一定的调节作用。在内群体关系中,大学生观点采择对助人行为的影响不仅需要借助于共情反应的部分中介效应而发挥作用,同时也存在一定的直接效应;在外群体关系中,大学生观点采择则完全借助于共情反应的中介效应而发挥作用,不存在显著的直接效应。     

室内照度对认知加工的影响:主观情绪和警觉性的中介作用

本研究采用单因素被试间设计,考察了白天室内照度(300 lx vs 1200 lx,眼位水平)对认知加工的影响及主观情绪和警觉性在照度水平与认知加工间的中介效应。结果发现:(1)被试在高照度照明条件下的认知加工绩效(Go/No-go,2-Back)明显好于低照度照明;(2)高照度照明对积极情绪和主观警觉性具有显著的正向影响;(3)警觉性在照度水平对Go/No-go任务的影响中起着完全中介作用,情绪的中介作用不显著。这表明警觉性在室内照度与部分认知加工间扮演着重要的"桥梁"作用。     

共同内群体认同对心理融合的促进效应及其机制

摘要：采用实验法从外显和内隐两个层面探讨共同内群体认同对心理融合的促进效应及其机制。实验1采用最简群体范式,通过重新范畴化操纵共同内群体认同,测量外显心理融合,结果发现,共同内群体认同显著促进了心理融合;实验2以民族群体为被试,采用GANT范式,从外显和内隐两个水平进一步探究共同内群体认同对民族心理融合的促进效应,结果发现,共同内群体认同促进了外显和内隐心理融合,感知相似性在共同内群体认同和心理融合间起中介作用。两个实验证明了共同内群体认同可以在外显和内隐两个水平促进心理融合,其促进作用是通过感知相似性实现的,也证实了GNAT范式在心理融合研究中的有效性。     

Problems in the neighbourhood: Formulating noise complaints across dispute resolution services

When people are in dispute with their neighbours, there are multiple routes to resolution, and different services have a range of remits to support it. This article explores how noise complaints are reported to dispute resolution mediation and local council environmental services in the United Kingdom. A collection of 315 recorded telephone calls were transcribed and analysed using discursive psychology, underpinned by conversation analytic methods. Analysis focused on how the same kinds of noise complaint were formulated for the remit and provision of the service called. In mediation calls, callers directly attributed the source of the noise to the agent of its production (e.g., “it's about the neighbour”). However, reference to “the neighbour” was typically omitted (at least initially) in calls to environmental health services (e.g., “I need to speak to someone about disturbance”). This comparative analysis of different settings reveals the significance of service remit for the design of complaints and the relevance of attributing cause in making a case for aid. Comparing two settings provides a propitious opportunity to demonstrate that noise is not a physically objective phenomenon or neutral category but institutionally formulated social conduct.     

Bias in cross-sectional analyses of longitudinal mediation

Most empirical tests of mediation utilize cross-sectional data despite the fact that mediation consists of causal processes that unfold over time. The authors considered the possibility that longitudinal mediation might occur under either of two different models of change: (a) an autoregressive model or (b) a random effects model. For both models, the authors demonstrated that cross-sectional approaches to mediation typically generate substantially biased estimates of longitudinal parameters even under the ideal conditions when mediation is complete. In longitudinal models where variable M completely mediates the effect of X on Y, cross-sectional estimates of the direct effect of X on Y, the indirect effect of X on Y through M, and the proportion of the total effect mediated by M are often highly misleading.     

More about linda or conjunctions in context

Abstract

Tversky and Kahneman (1982; 1983) reported that subjects rated the con junction of two events as more likely than one of the component events. This “conjunction effect” is an error in terms of formal probability, where the probability of more happening is always smaller than the probability of less. They explained this effect in terms of a “representativeness” heuristic. This paper focuses on the context of the problem and the suggestions implied by the questions in the task. The three studies reported here provide evidence that context effects and implicit suggestions alter subjects' judgements. Tvenky and Kahneman's models take no account of such factors. Two studies show that when implicit suggestions are reduced, subjects are much less prone to the conjunction “effect”. Subjects take being asked the question “Is person X a Y?”, as providing evidence that X may be Y.     

Mediation in experimental and nonexperimental studies: new procedures and recommendations

Mediation is said to occur when a causal effect of some variable X on an outcome Y is explained by some intervening variable M. The authors recommend that with small to moderate samples, bootstrap methods (B. Efron & R. Tibshirani, 1993) be used to assess mediation. Bootstrap tests are powerful because they detect that the sampling distribution of the mediated effect is skewed away from 0. They argue that R. M. Baron and D. A. Kenny's (1986) recommendation of first testing the X --> Y association for statistical significance should not be a requirement when there is a priori belief that the effect size is small or suppression is a possibility. Empirical examples and computer setups for bootstrap analyses are provided.     

“No More” leads to “Want More,” but “No Less” leads to “Want Less”: Consumers' counterfactual thinking when faced with quantity restriction discounts

The current research examines the impact of point‐of‐purchase (POP) discounts on consumers' counterfactual thinking (CFT). Study 1 reveals that consumers tend to engage in upward CFT (what might have been better) rather than downward CFT (what might have been worse) in response to POP discounts. Study 2 shows that upward CFT depends on how the discount information is framed. A discount with a lower‐quantity restriction (e.g., “X % off if you buy at least Y items”) leads consumers to counterfactually wish to buy more, but a discount with an upper‐quantity restriction (“X % off – limit Y items per customer”) leads consumers to wish to buy less. Study participants in both conditions report they would buy the same POP‐suggested amount, but for completely opposite reasons. In Study 3, this convergence effect in purchase quantity disappears when the maximum and minimum restrictions are lifted, suggesting that quantity restrictions in POP discounts guide quantity decisions.

On the inferential epistemics of trait centrality in impression formation

We provide a novel, inferential, account of the trait centrality phenomenon. We suggest that a trait possesses the property of “centrality” to the extent that it is subjectively deemed to imply other traits. Five studies explore four central elements of this view. First, trait relations can be stored as unidirectional rules (“if X then Y” but not necessarily “if Y then X”). Second, the strength of individuals' lay inference rules determines the effect of traits on impressions. Third, situationally manipulating the strength of lay inference rules influences the impact of traits on impressions. Fourth, the impact of an inference rule is reduced when it is difficult to discern the inference rule and when processing resources are limited. Copyright © 2009 John Wiley & Sons, Ltd.     

How do infants recognize joint attention?

The emergence of joint attention is still a matter of vigorous debate. It involves diverse hypotheses ranging from innate modules dedicated to intention reading to more neuro-constructivist approaches. The aim of this study was to assess whether 12-month-old infants are able to recognize a “joint attention” situation when observing such a social interaction. Using a violation-of-expectation paradigm, we habituated infants to a “joint attention” video and then compared their looking time durations between “divergent attention” videos and “joint attention” ones using a 2 (familiar or novel perceptual component) × 2 (familiar or novel conceptual component) factorial design. These results were enriched with measures of pupil dilation, which are considered to be reliable measures of cognitive load. Infants looked longer at test events that involved novel speaker and divergent attention but no changes in infants’ pupil dilation were observed in any conditions. Although looking time data suggest that infants may appreciate discrepancies from expectations related to joint attention behavior, in the absence of clear evidence from pupillometry, the results show no demonstration of understanding of joint attention, even at a tacit level. Our results suggest that infants may be sensitive to relevant perceptual variables in joint attention situations, which would help scaffold social cognitive development. This study supports a gradual, learning interpretation of how infants come to recognize, understand, and participate in joint attention.     

Causal agency and the perception of force

In the Michotte task, a ball (X) moves toward a resting ball (Y). In the moment of contact, X stops und Y starts moving. Previous studies have shown that subjects tend to view X as the causal agent (“X launches Y”) rather than Y (“Y stops X”). Moreover, X tends to be attributed more force than Y (force asymmetry), which contradicts the laws of Newtonian mechanics. Recent theories of force asymmetry try to explain these findings as the result of an asymmetrical identification with either the (stronger) agent or the (weaker) patient of the causal interaction. We directly tested this assumption by manipulating attributions of causal agency while holding the properties of the causal interaction constant across conditions. In contrast to previous accounts, we found that force judgments stayed invariant across conditions in which assignments of causal agency shifted from X to Y and that even those subjects who chose Y as the causal agent gave invariantly higher force ratings to X. These results suggest that causal agency and the perception of force are conceptually independent of each other. Different possible explanations are discussed.
