Decoding the implicit association test: Implications for criterion prediction

The implicit association test (IAT) is believed to measure implicit evaluations by assessing reaction times on two cognitive tasks, often termed “compatible” and “incompatible” tasks. A common rationale for studying the IAT is that it might improve our prediction and understanding of meaningful psychological criteria. To date, however, no clear psychometric theory has been advanced for this measure. We examine the theory, methods and analytic strategies surrounding the IAT in the context of criterion prediction to determine measurement and causal models a researcher embraces (knowingly or unknowingly) by using the test. Our analyses reveal that the IAT revolves around interpretation of two distinct relative constructs, one at the conceptual level and one at the observed level. We show that interest in relative implicit evaluations at the conceptual level imposes a causal model that is restrictive in form. We then examine measurement models of the IAT and show how computing a difference score at the observed level may lack empirical justification. These issues are highlighted in a study replicating an effect established in the literature (Study 1). We then introduce a new variant of the IAT and use it to evaluate the reasonableness of traditional IAT methods (Study 2).     

5～9岁儿童对心理过程差异的理解

对心理过程差异的理解是学龄后儿童心理理论发展的一部分。本文主要探讨5-9岁儿童对心理过程差异的理解,即理解两个体在看到同样的物体时思维过程是否相同。采用“思想泡泡”的方法给5岁、7岁、9岁各20名儿童讲述故事,考察故事中人物背景知识的有无、对象的不同(自我-他人/他人-他人)及对象间关系的不同(朋友/陌生人)对儿童判断心理过程差异的影响。结果发现,有无背景信息对儿童理解心理过程差异有显著影响,而故事中对象不同及对象之间关系的不同对儿童理解心理过程差异无显著影响。同时还发现,随着年龄的增长,儿童逐渐意识到两个体的思维过程是不同的且能提供比较充分的解释,对心理过程差异的理解使学龄后儿童对个体独特性有更深的了解。     

Decision making in a dynamic situation: The effect of false alarms and time pressure

An experiment was conducted to investigate the effect of a priori probability of false alarms and time pressure on decision-making behaviour in a dynamic task environment. In order to assess whether strategy selection in a dynamic task environment would be adaptive, we modelled the task mathematically, and compared actual decision strategies to the optimal ones. In addition to the selected strategy, we also studied decision-making behaviour at a lower operational level, reflecting the amount of effort subjects are willing to spend on the decision process. Subjects were required to monitor the fitness level of a simulated athlete, who was running a race, and had to provide treatments whenever the athlete's fitness level suggested a real physiological problem. When a decline of the athlete's fitness was caused by a false alarm, a spontaneous recovery would occur after some time, without any need for intervention. Time pressure was manipulated by the rate at which the athlete's fitness level declined. Overall, subjects did not select the most efficient strategy: they dominantly selected information before applying an action, even though it would have been more profitable, and less effortful, just to apply actions. At the operational level, subjects appeared to invest less effort when the probability of false alarms increased and to invest more effort when time pressure increased. However, in contrast to the outcomes of our mathematical model, subjects adjusted the amount of intervention to the a priori probability of false alarms and not to time pressure. Together, the results indicate that the selection of a decision strategy in a dynamic task is less adaptive then is generally concluded from studies with static tasks.     

A Propositional Dynamic Logic with Qualitative Probabilities

This paper presents an -completeness theorem for a new propositional probabilistic logic, namely, the dynamic propositional logic of qualitative probabilities (D Q P), which has been introduced by the author as a dynamic extension of the logic of qualitative probabilities (Q P) introduced by Segerberg.     

Is Adolescent Adjustment Following Parental Divorce a Function of Predivorce Adjustment?

This study examined whether adolescent adjustment problems which previously have been attributed to parental divorce exist prior to the divorce. Three groups (to-be-divorced, remain intact, and already divorced) were examined across four domains of adolescent functioning reported by multiple informants. The results indicated that adolescents from the to-be-divorced group functioned similarly to those who would remain in intact families but better than those in the already divorced group, suggesting that differences can be attributed to parental divorce and its accompanying disruption of family processes. Two of these processes, interparental conflict and parenting, were examined and failed to receive support.     

注意捕获与自上而下的加工过程

注意捕获对揭示两种控制过程——自下而上的加工与自上而下的加工之间的关系有着重要的研究意义。在当前对注意捕获的研究中,主要存在两大类的实验范式：线索化范式与视觉搜索范式;涉及以下几个方面：刺激驱动的注意捕获与自上而下控制的关系;注意捕获是否涉及注意的空间转移;刺激的显著性对注意捕获的影响;实验范式对注意捕获的影响。总的来说,没有任何一种视觉刺激能绝对的独立于自上而下的控制之外来捕获注意,因此也可以这样认为,注意捕获被默认为是一种自动化的过程,但这个自动化的过程可以被内源性的调节所抑制或者易化。     

人际责任归因与助人意愿的关系

人际责任归因研究是归因研究与责任推断相结合的一个新领域,它将归因理论应用于对他人失败行为的责任分析之中,为行为责任的推断提供了一个崭新的视角。本研究结合助人行为探讨人际责任归因与助人意愿之间的内在联系,204名教育硕士生和大学生被试参与了此项研究,并通过EQS建立了有关归因的控制性、情感反应、责任推断以及助人行为之间关系的结构方程模型。研究结果支持Weiner的人际责任归因理论假设,并且表明在归因与助人意愿关系模型中责任推断与情感反应是双向的而非单向的关系。     

Cognitive and social comparison processes in brainstorming

This brainstorming experiment assessed the extent to which idea exposure produced cognitive stimulation and social comparison effects. One hundred and sixty participants were exposed to either a high or low number of common or unique ideas. The participants’ likelihood of engaging in social comparison processes (high or low) was also manipulated through instructional sets. The results indicated both cognitive stimulation and social comparison effects. Exposure to a high number of ideas and to common ideas enhanced the generation of additional ideas. The effects of exposure to a high number of ideas was greater under high than under low social comparison conditions. Finally, recall of exposed ideas was related to enhanced idea generation. These results are consistent with the social/cognitive influence model of group brainstorming (Paulus, Dugosh, Dzindolet, Putman, & Coskun, 2002).     

Contingent approaches to making likelihood judgments about polychotomous cases: the influence of task factors

Two experiments tested the influence of three task factors on respondents' tendency to use normative, heuristic, and random approaches to making likelihood judgments about polychotomous cases (i.e., cases in which there is more than one alternative to a focal hypothesis). Participants estimated their likelihood of winning hypothetical raffles in which they and other players held various numbers of tickets. Responding on non‐numeric scales (vs. numeric ones) and responding under time pressure (vs. self‐paced) increased participants' use of a comparison‐heuristic approach, resulting in non‐normative judgment patterns. A manipulation of evidence representation (whether ticket quantities were represented by numbers or more graphically by bars) did not have reliably detectable effects on processing approaches to likelihood judgment. The authors discuss the implications of these findings for the further development of likelihood judgment theories, and they discuss parallels between contingent processing in choice and contingent processing in likelihood judgment.
