Reliability of implicit self‐esteem measures revisited

This study investigated the internal consistencies and temporal stabilities of different implicit self‐esteem measures. Participants (N = 101) responded twice—with a time lag of 4 weeks—to five different tasks: the Implicit Association Test (IAT), the Brief Implicit Association Test (BIAT), the Affective Priming Task (APT), the Identification‐Extrinsic Affective Simon Task (ID‐EAST) and the Name‐Letter Task (NLT). As expected, the highest reliability coefficients were obtained for the self‐esteem IAT. Importantly, the internal consistencies and the temporal stabilities of the APT, the ID‐EAST, and the NLT were substantially improved by using material, structural, and analytic innovations. In particular, the use of the adaptive response‐window procedure for the APT, the computation of error scores for the ID‐EAST, and the computation of a double corrected scoring algorithm for the NLT yielded reliability coefficients comparable to those of the established IAT. Implications for the indirect assessment of self‐esteem are discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

When old and frail is not the same: Dissociating category and stimulus effects in four implicit attitude measurement methods

It is not always clear whether implicit attitude measures assess the attitude towards single stimuli or the attitude towards categories. Nevertheless, this is important to know—both for interpreting implicit attitude effects and for selecting the test that is most appropriate for individual research aims. We investigated this for four implicit measures: the standard Implicit Association Test (IAT), the IAT-recoding free (IAT-RF), and two versions of the Extrinsic Affective Simon Task (EAST, identification (ID)-EAST). Effects in the standard IAT reflect evaluations of categories and single stimuli, whereas the IAT-RF measures attitudes towards categories only. Both versions of the EAST measure evaluations of single stimuli independently from the evaluation of categories. Three different effect sources are distinguished: attitudes towards single stimuli (IAT; EAST and ID-EAST), attitudes towards target categories (IAT and IAT-RF), and processes of recoding (IAT), which do not necessarily reflect attitudes.     

Implicit attitudes towards meat and vegetables in vegetarians and nonvegetarians

Previous research, in which self‐report measures were used, showed that vegetarians have more negative beliefs about meat than nonvegetarians. An important limitation of this research is that it did not examine differences in spontaneous affective reactions (i.e., implicit attitudes) towards meat and other types of food. We therefore conducted a new study in which not only self‐report measures were used, but also two tasks that have been developed to measure implicit attitudes: The Implicit Association Test (IAT) and a pictorial version of the Extrinsic Affective Simon Task (EAST). Both the IAT and EAST revealed that implicit attitudes towards vegetables (as compared to implicit attitudes towards meat) were more positive in vegetarians than in nonvegetarians. In line with previous findings, the self‐report measures showed that, compared to nonvegetarians, vegetarians had more positive attitudes towards vegetables and more negative attitudes towards meat. The IAT and EAST measures both correlated in the expected manner with self‐reported attitudes. A logistic regression showed that self‐reported attitudes were an almost perfect predictor of group status (vegetarian or nonvegetarian), and that adding the IAT and EAST measures as predictors did not improve prediction of group status. The results suggest that vegetarians and nonvegetarians differ in their spontaneous affective reaction towards vegetables or meat, and provide further evidence for the validity of the IAT and EAST as measures of inter‐individual differences in attitudes. Implicit attitudes could influence eating behaviour indirectly by biasing the decision to become a vegetarian or by determining how difficult it is for someone to maintain a vegetarian diet.     

Does the Implicit Association Test for assessing anxiety measure trait and state variance?

The stability of the Implicit Association Test for assessing anxiety (IAT‐Anxiety) is lower than its internal consistency, indicating that the IAT‐Anxiety measures both stable and occasion‐specific variance. This suggests that the IAT‐Anxiety may be not only a valid measure of trait anxiety but also one of state anxiety. To test this assumption, two studies were conducted in which state anxiety was experimentally induced by a public speaking task. However, both studies showed that the IAT‐Anxiety score did not change when a state of anxiety was induced. Thus, it seems that occasion‐specific factors other than variations in state anxiety lead to occasion‐specific variance in the IAT‐Anxiety score. Implications for the indirect assessment of personality dispositions with the IAT are discussed. Copyright © 2004 John Wiley & Sons, Ltd.     

内隐自尊的特性：来自EAST的证据

采用外部情绪性Simon任务（EAST）对109名大学生对代表自我和他人的刺激词的态度差异进行测量,从而探讨内隐自尊的特性。结果显示：在个体的认知图式中,对自我持有一种内隐的积极的评价或态度,对他人持有一种内隐的相对消极的评价或态度。具体表现在：（1）内隐自尊的特性是将自己与积极的评价和情感相联系,将他人与消极的评价和情感相联系;（2）自我姓名激活的积极的内隐自我态度比一般性自我词更为强烈,而他人姓名激活的消极的内隐态度比一般性非我词更弱。本研究表明,EAST能有效检测出内隐自尊效应,并可以同时获得个体对自我和他人的内隐态度的强度和方向,为内隐自尊研究提供了一种新的有效的方法,但其应用仍需谨慎。     

Cognitive processes in the Extrinsic Affective Simon Task: a task-set switching account of EAST effects

Recently, De Houwer (2003) introduced the Extrinsic Affective Simon Task (EAST) as a new procedure for the indirect assessment of attitudes. In the present paper, we propose an explanation of EAST effects based on a task-set switching account. Specifically, we argue that EAST effects result from difficulties in efficiently switching between two different task sets. Results from two experiments support the assumptions of the task-set switching account: While there were strong EAST effects in task-shift trials, no robust effects were found in task-repetition trials. In Experiment 2, the robustness of this task-shift effect on the EAST was demonstrated: Visual similarity between concept and attribute stimuli did not qualify the task-shift effects. Implications for the interpretation of EAST effects are discussed.     

The extrinsic affective Simon task as an instrument for indirect assessment of prejudice

We report one study that explored the applicability of the Extrinsic Affective Simon Task (EAST) as an indirect measure of prejudice. The EAST detected known differences in reactions revealing that a Turkish outgroup was spontaneously evaluated more negatively than the German ingroup. More importantly, EAST effects were meaningfully correlated with measures of explicit prejudice expression. This relation, however, was moderated by participants' motivation to control prejudice expression. In addition, we tested considerations regarding the role of a task‐switch account for the explanation of EAST scores and found that only EAST scores of task‐switch trials were related to explicit prejudice expression. This supports a task‐switch explanation of the EAST. Results indicate that the EAST is suitable for the assessment of interindividual differences in intergroup prejudice. Implications for the indirect assessment of automatic prejudice activation are discussed. Copyright © 2008 John Wiley & Sons, Ltd.     

基于反应时范式的内隐社会认知研究方法

三种新的内隐社会认知研究方法－－IAT、GNAT和EAST,这些方法采用反应竞争任务,考察概念间的联结强度。IAT通过对个体在不同任务上的操作,考察不同目标与属性间的联系、GNAT考察某一特定对象和评价间的联系;EAST考察被试在一个任务上的操作来推断个体对目标的评价。     

内隐自尊与外显自尊的关系:多重内隐测量的视角

本研究以102名大学生为被试,从多重内隐测量的视角出发,运用内隐联想测验（IAT）、Go／No-go联想任务（GNAT）和外部情绪性Simon任务（EAST）三种实验程序对内隐自尊及其特性进行了测量和研究,同时运用结构方程建模对内隐自尊和外显自尊的结构关系进行了探讨。结果表明：（1）IAT、GNAT和EASI这三种基于反应时范式的内隐自尊测量方法是有效的,均能有效检测出内隐自尊效应,内隐自尊的特性表现为个体倾向于将自我与积极属性或事物相联,将他人与消极属性或事物相联;（2）内隐自尊与外显自尊是分离的结构,两者是相对独立的两个自我评价系统,支持内隐自尊和外显自尊的两维结构说;（3）双重态度模型和信息加工双过程模型两种理论模型都可以解释内隐自尊和外显自尊的分离现象。     

Specific predictive power of automatic spider-related affective associations for controllable and uncontrollable fear responses toward spiders

This study examined the predictive power of automatically activated spider-related affective associations for automatic and controllable fear responses. The Extrinsic Affective Simon Task (EAST; De Houwer, 2003) was used to indirectly assess automatic spider fear-related associations. The EAST and the Fear of Spiders Questionnaire (FSQ) were used to predict fear responses in 48 female students from Maastricht University with varying levels of spider fear. Results showed that: (i) the EAST best predicted automatic fear responses, whereas (ii) the FSQ best predicted strategic avoidance behavior. These results suggest that indirect measures of automatic associations may have specific predictive power for automatic fear responses.     

Temporal dynamics of interference in Simon and Eriksen tasks considered within the context of a dual-process model

Behavioral and brain potential measures were employed to compare interference in Eriksen and Simon tasks. Assuming a dual-process model of interference elicited in speeded response tasks, we hypothesized that only lateralized stimuli in the Simon task induce fast S–R priming via direct unconditional processes, while Eriksen interference effects are induced later via indirect conditional processes. Delays to responses for incongruent trials were indeed larger in the Eriksen than in the Simon task. Only lateralized stimuli in the Simon task elicited early S–R priming, maximal at parietal areas. Incongruent flankers in the Eriksen task elicited interference later, visible as a lateralized N2. Eriksen interference also elicited an additional component (N350), which accounted for the larger behavioral interference effects in the Eriksen task. The findings suggest that interference and its resolution involve different processes for Simon and Eriksen tasks.     

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).     

Assessment of multiple implicit self‐concept dimensions using the Extrinsic Affective Simon Task (EAST)

This study explored the psychometric properties of the Extrinsic Affective Simon Task (EAST; De Houwer, 2003a ) as adapted for the measurement of the implicit self‐concept of personality. The EAST was adapted to allow the simultaneous assessment of the three traits shyness, anxiousness, and angriness. In order to test the EAST's psychometric properties, 100 participants completed a trait EAST, Implicit Association Tests (IATs), and direct self‐ratings. The EAST showed low internal consistencies and correlated neither with the IATs nor with the direct measures. The main problem of the EAST, namely its low reliability, is discussed, and general conclusions regarding the indirect assessment of the personality self‐concept by EASTs are derived.

Assessing automatic activation of valence: a multinomial model of EAST performance

The Extrinsic Affective Simon Task (EAST; De Houwer, 2003) has been introduced as an indirect measure of automatic activation of valence. EAST effects provide nonrelative valence measures of single stimuli compared to relative measures (e.g., Implicit Association Test) that imply a comparison between two stimuli or concepts. However, EAST effects can be biased by response tendencies. A multinomial process dissociation model of EAST performance is proposed and successfully validated in four experiments. Its parameters provide pure and unbiased measures of automatic valence activation, controlled processing of task-relevant features, and response tendency. A first application of latent-class hierarchical multinomial models reveals a significant amount of parameter heterogeneity resulting from interindividual differences in accuracy motivation.     

Relations between implicit and explicit measures of attitudes and measures of behavior: evidence of moderation by individual difference variables

The moderating role of individual difference variables (Self-Reported Habit Index [SRHI], Need for Cognition [NFC]) on relationships between implicit (Implicit Association Test [IAT], Extrinsic Affective Simon Test [EAST]) or explicit measures of attitude and behavior is assessed in two studies. A dissociation pattern is found on self-report diary measures of behavior. In Study 1, the EAST-behavior relationship is moderated by SRHI; explicit measures of the attitude-behavior relationship are moderated by NFC. In Study 2, the IAT-behavior relationship is moderated by SRHI; explicit measures of the attitude-behavior relationship are moderated by NFC. Higher levels of SRHI and NFC are associated with stronger relationships between the implicit or explicit measures of attitude and the measure of behavior. In Study 2, the SRHI x IAT interaction is replicated for an objective behavior measure. Implications for understanding the relationship between implicit and explicit measures of attitudes and measures of behavior are discussed.     

Trial-to-trial sequential dependencies in a social and non-social Simon task

Recent research has shown that joint-action effects in a social Simon task provide a good index of action co-representation. The present study aimed to specify the mechanisms underlying joint action by considering trial-to-trial transitions. Using non-social stimuli, we assigned a Simon task to two participants. Each was responsible for only one of two possible responses. This task was performed alone (Individual go/nogo task) and in cooperation with another person who was sitting alongside (Joint go/nogo task). As a further control task, we added a Standard Simon task. Replicating previous findings (Sebanz et al. in Cognition 88:B11-B21, 2003), we found no spatial compatibility effect in the Individual go/nogo task but we did find one in the Joint go/nogo task. A more detailed analysis showed that a sequential modulation of the Simon effect was present in both the Joint and the Individual go/nogo tasks. We found reliable Simon effects in trials following Simon compatible trials not only in the Joint go/nogo task but also to a somewhat smaller extent in the Individual go/nogo task. For both these go/nogo tasks, sequential modulation effects were stronger for nogo/go transitions than for go/go transitions. This suggests that low-level feature binding and repetition mechanisms contribute to the social Simon effect related to the specific requirement not to respond on nogo trials.     

Implicit associations between anxiety-related symptoms and catastrophic consequences in high anxiety sensitive individuals

Anxiety sensitivity refers to the fear of anxiety-related physical sensations arising from beliefs that these sensations have harmful consequences (Reiss & McNally, 1985). The present study examined whether individuals with high (vs. low) anxiety sensitivity show stronger implicit associations in memory between anxiety-related symptoms, as opposed to neutral body parts, and harmful, as compared to harmless, consequences. A total of 22 undergraduate students (14 F, 8 M) completed the Extrinsic Affective Simon Task (EAST; De Houwer, 2003). Results indicated that high anxiety sensitive individuals (n = 10) tended to implicitly associate harmful consequences with anxiety-related symptoms. Their performance was significantly faster on trials where target words related to anxiety symptoms were mapped on to the same response key as harmful consequences. No significant difference in performance was found for low anxiety sensitive individuals (n = 12) or when target words were body parts unlikely related to diseases. Between-group differences persisted after controlling for trait anxiety and history of panic attacks, but not when illness-related beliefs were introduced as a covariate. Identifying this implicit association bias provides additional empirical support for the concept of anxiety sensitivity.     

中国人人际情感的差序格局关系:来自EAST的证据

本研究采用外部情感西蒙任务(EAST),以36名大学生为被试对自我词及亲人、熟人、陌生人三种人际关系词与积极情感和消极情感的关系进行探究,从而检验个体对自我和不同人际关系对象的情感是否存在差序格局的表现形式。结果显示,在EAST中,对自我词和亲人词作积极反应比作消极反应时间更短;对陌生人词作消极反应比作积极反应时间更短;对熟人词作积极反应和消极反应的时间差异不明显。并且,自我词的EAST效应值最大,接着依次是亲人词和熟人词;陌生人词的EAST效应值为负值。表明了在个体的认知图式中,对自我、亲人持有积极的情感,而对陌生人持有消极的情感,对熟人情感偏向不明显;且不同人际关系在情感的联结强度上表现出差序格局的形式。     

冲突适应效应是领域特定的

本研究采用整合的交叉任务范式,通过任务类型的操纵,对冲突适应效应是领域一般的还是领域特定的问题进行了探讨。结果发现当时,在刺激-反应集为4的字母flanker+Simon的整合交叉任务中和刺激-反应集为4的Stroop+Simon的整合交叉任务中,冲突适应效应都是仅存在于任务内,不存在于任务间。说明在控制了重复启动效应且排除了任务之间维度重叠的影响后,两种类型的整合交叉任务都只在任务内观察到冲突适应效应。这表明在控制特征整合的影响后,冲突适应效应是领域特定的,同时说明冲突监测系统不仅是对冲突进行监测,也对冲突的来源进行识别。
