Feature-based versus category-based induction with uncertain categories

Previous research has suggested that when feature inferences have to be made about an instance whose category membership is uncertain, feature-based inductive reasoning is used to the exclusion of category-based induction. These results contrast with the observation that people can and do use category-based induction when category membership is known. The present experiments examined the conditions that drive feature-based and category-based strategies in induction under category uncertainty. Specifically, 2 experiments investigated whether reliance on feature-based inductive strategies is a product of the lack of coherence in the categories used in previous research or is due to the use of a decision-only induction procedure. Experiment 1 found that feature-based reasoning remained the preferred strategy even when categories with relatively high internal coherence were used. Experiment 2 found a shift toward category-based reasoning when participants were trained to classify category members prior to feature induction. Together, these results suggest that an appropriate conceptual representation must be formed through experience with a category before it is likely to be used as a basis for feature induction.     

Category-Based and Feature-Based Cognitive Processes: The Role of Unfavorable Information1

Recent research on selection decisions suggests that favorable features (e.g., attractive physical features or positively-evaluated personality traits) can enhance ratings of applicant suitability, but little research has examined the impact of unfavorable features. Theories of person perception distinguish between two information processing strategies: category-based and feature-based. We predicted that unfavorable features would influence selection decisions only when raters used feature-based processing strategies. Results suggest that applicant features' prototypicality and favorability can compensate for one another, with applicants' negative features resulting in a disadvantage only when the applicant is perceived as nonprototypical.     

The influence of Afrocentric facial features in criminal sentencing

Prior research has shown that within a racial category, people with more Afrocentric facial features are presumed more likely to have traits that are stereotypic of Black Americans compared with people with less Afrocentric features. The present study investigated whether this form of feature-based stereotyping might be observed in criminal-sentencing decisions. Analysis of a random sample of inmate records showed that Black and White inmates, given equivalent criminal histories, received roughly equivalent sentences. However, within each race, inmates with more Afrocentric features received harsher sentences than those with less Afrocentric features. These results are consistent with laboratory findings, and they suggest that although racial stereotyping as a function of racial category has been successfully removed from sentencing decisions, racial stereotyping based on the facial features of the offender is a form of bias that is largely overlooked.     

陌生面孔的印象加工:基于面孔特征的视角

个体往往会基于面孔特征对他人进行特质推断和社会评价,这种推进和评价会影响个体的行为决策。结合印象形成的双加工理论和面孔加工的双通路模型,本文提出陌生面孔的印象加工主要包括两类方式:一是基于社会分类线索及相似特征的加工,激活个体的刻板印象;二是基于熟悉面孔的相似性特征线索,通过过度泛化激活与熟悉他人相一致的印象。本文进一步阐述了两类面孔线索印象加工的过程和影响陌生面孔印象加工的相关因素。在此基础上,本文提出现有的研究对两类加工方式的交互作用及其加工阶段尚未作深入探讨,同时指出知觉者本人的人格特质和面孔信息对印象加工的影响也需要在未来研究中进一步探索。     

THE EFFECTS OF APPLICANTs' REACTIONS TO COGNITIVE ABILITY TESTS AND AN ASSESSMENT CENTER

Manufacturing applicants' perceptions of two selection devices were examined. In Study 1, applicants ( n = 3,984) completed cognitive ability tests and a survey of reactions. In Study 2, a subset of applicants from Study 1 ( n = 194) participated in an assessment center and completed the survey. Applicants reacted favorably to the procedures but viewed the assessment center as more face valid than the cognitive tests. Applicants who perceived the selection techniques more favorably were also more satisfied with the selection process, the job, and the organization. Although applicants' perceptions of the procedures were related to job acceptance intentions, applicants' liking of the job and organization explained the largest unique variance. In future studies, applicants' job acceptance intentions and attitudes toward the job and organization should be assessed before and after administration of selection devices; not controlling for prior impressions resulted in overestimation of the contribution of applicants' perceptions of selection procedures.     

Perceiving facial expressions

Three experiments investigated the perception of facial displays of emotions. Using a morphing technique, Experiment 1 (identification task) and Experiment 2 (ABX discrimination task) evaluated the merits of categorical and dimensional models of the representation of these stimuli. We argue that basic emotions—as they are usually defined verbally—do not correspond to primary perceptual categories emerging from the visual analysis of facial expressions. Instead, the results are compatible with the hypothesis that facial expressions are coded in a continuous anisotropic space structured by valence axes. Experiment 3 (identification task) introduces a new technique for generating chimeras to address the debate between feature-based and holistic models of the processing of facial expressions. Contrary to the pure holistic hypothesis, the results suggest that an independent assessment of discrimination features is possible, and may be sufficient for identifying expressions even when the global facial configuration is ambiguous. However, they also suggest that top-down processing may improve identification accuracy by assessing the coherence of local features.     

The Effect of Name on Pre‐Interview Impressions and Occupational Stereotypes: The Case of Black Sales Job Applicants

Name is an important, yet under‐researched racial cue that can affect evaluators' opinions, attitudes, and beliefs about minority job applicants. This study examined a two‐way ANOVA interaction between name and sales job type on White sales professionals' pre‐interview impressions of Black applicants. Results indicated a significant interaction between applicant name and sales job type on pre‐interview impressions. For outside sales jobs, Anglicized‐named applicants received more favorable pre‐interview impressions than did ethnic‐named applicants. In addition, pre‐interview impressions of Anglicized‐named applicants were more favorable for outside versus inside sales jobs. Findings, implications, limitations, and future research directions are discussed.     

The careless or the conscientious : Who profits most from goal progress?

Although research indicates that making progress on personal work goals predicts positive job attitudes, little is known about the role of conscientiousness in moderating this relationship. Congruence theories suggest that job attitudes will be more dependent on goal progress when employees are high in conscientiousness, whereas compensation theories suggest the opposite. We test these competing hypotheses in a three-wave, 4-month longitudinal panel study of 121 trainee teachers, who are at their early stages of career development. Conscientiousness moderated the relationships between progress on personal work goals and job attitudes according to the compensatory pattern, such that employees displayed stronger increases in job satisfaction and affective organizational commitment in response to goal progress when they were low rather than high in conscientiousness. Our results help to resolve conflicting findings about the relationship between goal progress and job attitudes and adjudicate competing hypotheses about the role of conscientiousness in moderating this relationship.     

Enactment effects and integration processes in younger and older adults’ memory for actions

The present study investigates the mental processes that are applied to previously attended items of working memory. In an object-switching task, participants counted the number of sequentially presented objects. In Experiment 1 the processing time increased when the object category switched from the prior trial compared to a repetition. More importantly, the further in the past the last instance of a current category was presented, the more processing time was necessary—an observation suggesting passive decay rather than inhibition of previously attended items. However, results differed when only two object categories were employed. Experiment 2 suggests that the lack of a clear indication of decay with small numbers of categories was due to participants’ expectancy of category switches rather than repetitions. Taken together, the results suggest that working memory items become less accessible the longer they have not been attended to, when strategic processes are controlled.     

On the costs of refocusing items in working memory: a matter of inhibition or decay?

The present study investigates the mental processes that are applied to previously attended items of working memory. In an object-switching task, participants counted the number of sequentially presented objects. In Experiment 1 the processing time increased when the object category switched from the prior trial compared to a repetition. More importantly, the further in the past the last instance of a current category was presented, the more processing time was necessary - an observation suggesting passive decay rather than inhibition of previously attended items. However, results differed when only two object categories were employed. Experiment 2 suggests that the lack of a clear indication of decay with small numbers of categories was due to participants' expectancy of category switches rather than repetitions. Taken together, the results suggest that working memory items become less accessible the longer they have not been attended to, when strategic processes are controlled.     

Implicit Attitudes as Potential Protection From Risky Sex: Predicting Condom Use With the IAT

The Implicit Association Test (Greenwald, McGhee, & Schwartz, 1998) has become a popular tool for measuring implicit attitudes toward 2 contrasting concepts. In this study, we suggest including a neutral category (trees) to capture implicit evaluations of a single target attitude object. Using such a technique to measure implicit attitudes toward condoms, we predicted and found that explicit attitudes were related to intended condom use in situations that allow for controlled and deliberative processing, but implicit attitudes were related to intended condom use when automatic processing presides. Implications for such implicit and explicit attitude-behavior relations are discussed in the context of sexual risk-taking.     

When learning to classify by relations is easier than by features

Relational reasoning is often considered more resource intensive than feature-based reasoning. This view implies that learning categories defined by relational regularities should be more difficult than learning categories defined by featural regularities. Unfortunately previous studies do not ground featural and relational information in a common perceptual substrate. After addressing this concern, a series of experiments compare learning performance for relation- and feature-based categories. Under certain circumstances we find faster learning for relation-based categories. The results suggest that mechanisms rooted in relational processes (e.g., relative stimulus judgement, analogical comparison) facilitate or hinder learning depending on whether the relational processes highlight or obscure the underlying category structure. Conversely, category learning affects relational processes by promoting relational comparisons that increase the coherence of acquired categories. In contrast to the largely independent research efforts in category learning and analogy research, our findings suggest that learning and comparison processes are deeply intertwined.     

Typicality and group variability as dual moderators of category-based inferences

We propose and test two alternative hypotheses bearing on the dual roles of group variability and typicality when people form impressions of single category members. The latitude of acceptance hypothesis suggests that a wider range of individual group members are likely to be seen as good-fitting members (i.e., typical) if the group is heterogeneous, thereby increasing the extent to which stereotypical attitudes are used as a basis for responding to these persons. In contrast, the typicality-functionality hypothesis suggests that typicality plays different roles depending on group variability. This view suggests that typicality plays the “gatekeeper function” as postulated by Fiske and Neuberg (1990) when the group is homogeneous, but not when it is heterogeneous. Across two studies, stronger support was found for the typicality-functionality hypothesis. Implications for the extant literature on category-based processing are discussed.     

阻碍效应范式中主题知识对类别学习的影响

三个实验采用阻碍效应研究范式探讨主题知识对类别学习的影响。实验1探讨定义特征维度为机械特征时,主题知识对类别学习的影响;实验2和实验3,通过考察定义特征维度为知识特征时,类别学习中阻碍效应的大小,继续探讨主题知识对类别学习的影响。实验结果发现：（1）当定义特征维度为机械特征时,主题知识的存在没有促进类别学习。这可能因为定义特征维度为机械特征,主题知识难以发现所致;（2）当定义特征维度为知识特征时,类别学习中的阻碍效应消失,证明主题知识的存在促进了类别学习。研究结果再次支持了类别学习不仅仅受到减少归类错误驱动的观点。     

Exposing Individuals to Foreign Accent Increases their Trust in What Nonnative Speakers Say

People are more likely to believe things that are easier to process. Foreign-accented speech is relatively difficult to process, and prior research shows that, correspondingly, people believe information less when it is delivered in a foreign accent rather than a native accent. Here we show that a short exposure to foreign accent can reduce this bias, and that the reduction in bias is due to improvement in the processing of the accent. These results demonstrate how cognitive aspects of language processing can influence attitudes. The results also suggest that ensuring exposure to foreign accent can reduce discrimination against nonnative speakers.     

Further Distinctions between Coping and Defense Mechanisms?

In the current literature there is a great confusion between coping and defense mechanisms. As Cramer (1998) points out, a distinction between them is both possible and worthwhile in that they possess different cognitive features. Cramer proposes two basic criteria: the conscious/unconscious and the intentional/unintentional nature of the processes. We focus on a further criterion, the manipulation versus revision of one's mental attitudes, which so far has been neglected in the relevant literature. We suggest that responses to adversity implying manipulation are typical of defense mechanisms, while those implying the revision of one's mental attitudes characterize coping strategies. Finally, we address emotion-focused coping as the area where coping and defense meet, and we suggest that responses displaying defensive features should be excluded from the category of coping in accordance with the distinctions identified.     

Off‐Target? Changing Cognitive‐Based Attitudes

Researchers argue that the effectiveness of cognitive versus affective persuasive appeals depends in part on whether the appeal is congruent or incongruent with a primarily cognitive or affective attitude base. However, considerable research suggests that these persuasion effects may hold only for predominantly affective attitudes and not cognitive attitudes. Indeed, results of Experiment 1 show that the relative effectiveness of congruent relative to incongruent persuasion appeals holds for brands with predominantly affective associations, but not those with predominantly cognitive associations. Experiment 2 explores one reason for this anomalous finding: Cognitive attitudes may be relatively impervious to persuasive appeals because the probability of targeting the specific attribute on which the cognitive attitude is based is smaller. The results are supportive, showing that significant persuasion effects are found when the specific beliefs on which cognitive attitudes are based are taken into account. However, these effects only occur under conditions of low cognitive load and not high cognitive load where resources for the cognitive processing of the appeals are limited. We discuss the implications of the research for the role of attitude structure in understanding persuasion effects and the interplay of affective and cognitive elements in persuasion processes.     

The Cognitive and Interpersonal Costs of Video

As advances in communication technology proliferate, organizations are rapidly incorporating new communication media into their environment. Unfortunately, not much is known about the effect of communication technologies on the processing of interpersonal information. Interactive communication media that place more cognitive demands on interactants may impoverish the process of impression formation. Today's video, because of the additional information conveyed and problems with signal quality, may reduce systematic processing of information and interfere with the impression-formation process. Three studies explore the relationship between communication media, cognitive load, and impression formation. Study 1 establishes that interacting over an audio-video system requires more cognitive load than does interacting over audio only. Study 2 replicates work by Ford and Kruglanski (1995) that finds that people's impressions are more biased toward a primed trait under high cognitive load. Study 3 assesses the impact of audio-only and audio-video media on impression formation. As expected, participants in Study 3 formed impressions more biased toward a primed trait when interacting over audio-video as compared to audio only. Implications for the design and use of communication media in organizations are discussed.     

嵌套范式下视空工作记忆对基于规则类别学习

基于COVIS模型与认知加工阶段假设,通过2个实验探讨嵌套范式下, 视空工作记忆对基于规则类别学习的影响。实验1采用类别学习中嵌套视空工作记忆的范式,结果发现视空工作记忆削弱基于规则类别学习成绩,与COVIS模型预测相一致。实验2则采用视空工作记忆中嵌套类别学习任务的范式,结果却发现视空工作记忆对基于规则类别学习的影响消失。实验结果表明嵌套范式下视空工作记忆的位置影响基于规则类别学习,初步验证了类别学习存在多个认知加工阶段的假设,视空工作记忆主要影响基于规则类别学习中规则的发现和检验阶段。
