The dimensional effects of missing information on choice processing

This paper demonstrates that choice processing may be different in missing information situations than in full information situations depending on whether inferences are used to fill in missing values and the overlap of the missing information itself. It is shown that when individuals do not form inferences to fill in missing values, fewer full attribute-based processes and more processes which accommodate for missing attribute values, alternative-based or given-dimension attribute-based, are used. It is also shown that when a processing shift due to missing information does occur, the overlap of the missing values will affect the type of shift that takes place. If overlap is high, a shift to given-dimension attribute-based processing is more likely, and when overlap is low, a shift to alternative-based processing is more likely. When individuals do form inferences to fill in missing values, processing is more similar to that in full information situations. Finally, it is shown that individuals will often partially fill in missing information, thus moderating the proposed effects.     

Category-based and attribute-based reactions to others: Some informational conditions of stereotyping and individuating processes

This paper suggests that people can form impressions in a variety of ways that range from primarily category-based processes to primarily attribute-based processes, and that the process partially depends on the configuration of available information. Easily categorized configurations are hypothesized to elicit relatively category-based processes, while not easily categorized configurations are hypothesized to elicit relatively attribute-based processes. In Experiment 1, subjects first rated the likability of job-category labels and relevant trait attributes, in isolation from each other. At a later session, stimulus people were depicted by category labels (occupations) and relevant attributes (traits) in varying combinations. Typicality ratings confirmed the manipulated ease of categorizing the various information combinations. Correlations between subjects' evaluations of each stimulus person and their independent prior ratings of the components supported the idea of a continuum anchored respectively by relatively category-based and by relatively attribute-based impression formation processes. In the second study, think-aloud data further supported the current hypotheses: subjects spontaneously examined the fit between category and attributes, and they used the attributes more in the attribute-based conditions than in the category-based conditions. The protocol data also reveal some processes intermediate on the continuum between primarily category-based and primarily attribute-based processes; these include subcategorizing, generating new categories, and self-reference. Social perceivers apparently use flexible impression formation processes, depending on the configuration of available information.     

Labeling bias and categorical induction: generative aspects of category information

When a person is characterized categorically with a label (e.g., Linda is a feminist), people tend to think that the attributes associated with that person are central and long lasting (S. Gelman & G. D. Heyman, 1999). This bias, which is related to category-based induction and stereotyping, has been thought to arise because a category label (e.g., feminist) activates the dominant properties associated with the representation of the category. This explanation implies that categorical information influences inferential processes mainly by conjuring up main attributes or instances represented in the category. However, the present experiments reveal that this attribute-based explanation of induction does not provide a complete picture of inferential processes. The results from 3 experiments suggest that category information can affect inferences of attributes that are not directly related to the category, suggesting that categories not only activate likely attributes but also help integrate unlikely or even unrelated attributes.     

Interfering with inferential, but not associative, processes underlying spontaneous trait inference

Three studies explore mental processes underlying spontaneous trait inferences about self-informants and the spontaneous trait transference characterizing third-party informants. Process differences are suggested in that instructions prompting a nontrait inference (truth or lie?) reduce self-informant trait-savings effects and lower self-informant trait judgments. For third-party informants, such instructions have no effect on these outcome variables. Results of a third study are inconsistent with cognitive load as an explanation for these effects. Taken together, these results indicate that inferences, and not merely associations, spontaneously form when processing information about self-informants. The results also show that the inferences and judgments that occur in spontaneous trait transference are not caused by the misidentification of third-party informants as self-informants.     

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.     

Can I trust you? Negative affective priming influences social judgments in schizophrenia

Successful social interactions rely on the ability to make accurate judgments based on social cues as well as the ability to control the influence of internal or external affective information on those judgments. Prior research suggests that individuals with schizophrenia misinterpret social stimuli and this misinterpretation contributes to impaired social functioning. We tested the hypothesis that for people with schizophrenia, social judgments are abnormally influenced by affective information. Twenty-three patients with schizophrenia and 35 healthy control participants rated the trustworthiness of faces following the presentation of neutral, negative (threat-related), or positive affective primes. Results showed that all participants rated faces following negative affective primes as less trustworthy than faces following neutral or positive primes. Importantly, this effect was significantly more pronounced for participants with schizophrenia, suggesting that schizophrenia may be characterized by an exaggerated influence of negative affective information on social judgment. Furthermore, the extent that the negative affective prime influenced trustworthiness judgments was significantly associated with patients' severity of positive symptoms, particularly feelings of persecution. These findings suggest that for people with schizophrenia, negative affective information contributes to an interpretive bias, consistent with paranoid ideation, when judging the trustworthiness of others. This bias may contribute to social impairments in schizophrenia.     

品牌印象研究述评

品牌印象是消费者基于对品牌信息的感知和体验而在头脑中留下的品牌部分或整体信息。品牌印象形成涉及到类别信息加工和个别化信息加工两方面,其认知加工模式还存在争议。品牌印象实证研究主要存在以品牌主观形象为核心的品牌印象研究和以品牌拟人化特征为焦点的品牌印象研究两条线路。在分析比较的基础上,我们认为无论是品牌形象研究线路还是品牌人格研究线路,探讨的都是品牌的客观特性在消费者头脑中留下的主观印象,其本质都是对消费者品牌印象的研究。品牌印象是品牌与消费者的关系基础。品牌建设的任务就是在深刻把握消费者品牌印象形成机制的基础上,通过调节和控制消费者对品牌的认知、联想、态度、信任和忠诚来积累品牌资产。     

P3b反映基于相似性的图形类别归纳决策过程(309)

先前关于归纳推理的研究没有探讨过图形类别归纳任务中决策过程的事件相关电位(ERPs)特征。该研究采用图形材料,通过记录和分析图形类别归纳推理任务的结论评估阶段的脑电信号,探讨了不同类别条件下图形归纳推理决策过程的ERP特征。实验结果显示,推理决策过程中,当前提为一些狗具有某种属性特征时,结论一致类别(狗类及马类)比结论不一致类别下(椅子类)的归纳推理诱发了更大的P3b的波幅; 而结论一致类别下,类别内(狗类)比类别外(马类)推理诱发更大的后部脑区的P3b的波幅,反映了相似性对类别归纳的贡献。该研究为理解类别归纳过程的决策阶段的动态加工过程提供了神经电生理学证据。研究结果进一步支持了类别归纳的相似性理论模型。     

Affective Influences on Judgments and Behavior in Organizations: An Information Processing Perspective

This article reviews and integrates recent research in experimental social psychology and organizational behavior demonstrating the pervasive influence that affective states or moods have on judgments, decision making, and behavior in organizations. An information processing theory, the Affect Infusion Model (AIM) is described that can account for many of the empirical findings and also provides a promising theoretical base for future research in this area. The article reviews a range of experimental and applied studies consistent with the predictions of this model, demonstrating the role of information processing strategies in moderating affective influences on organizational behavior. Specifically, we discuss the influence of affect on such work-related behaviors as worker motivation, creativity and performance, interpersonal judgments and communication, performance appraisal judgments and selection interviews, organizational spontaneity, employee flexibility and helpfulness, absenteeism, and bargaining and negotiation behaviors. The implications of the information processing approach for understanding the influence of affect on organizational behaviors are discussed, and we argue for the greater integration of affect into contemporary theorizing and research in organizational settings.     

The downside of categories

One of the primary uses of categories is to draw inferences about novel objects based on their category membership. In a recent study, Lagnado and Shanks show that people make different inferences about an object depending on whether they first categorize the object at a general or specific level. Indeed, their inference changes even though they have been given no information about the object. This finding reveals limitations of category-based induction.     

Regulatory fit from attribute‐based versus alternative‐based processing in decision making

This paper discusses the fit between attribute-based versus alternative-based processing and regulatory focus, and its impact on decision outcome valuation. Attribute-based processing was found to occur more frequently under prevention focus, whereas alternative-based processing occurred more frequently under promotion focus. The fit between prevention/promotion focus and attribute-based/alternative-based processing was found to enhance satisfaction with choices and the perceived monetary value of chosen options. Moreover, the effect of fit on outcome valuation was found to be mediated by ease of processing. Finally, the effects of fit on ease of processing and outcome valuation disappeared when consumers first practiced to process information based on either attributes or alternatives.     

The influence of ethnicity,social class,and context on judgments about U.S. women

In 2 studies, the authors investigated impression formation as influenced by category-based stereotypes associated with ethnicity and social class. The participants in Study I made judgments about 1 target woman, described as interested in running for office in the Parent Teacher Organization (PTO) of her children's school. The hypothetical woman was presented to the respondents along with her photograph and information about her ethnic background (Anglo-Saxon, Latina, or Jewish) and occupation (middle class or working class). In Study 2, the authors changed the context and presented a younger target woman (also varied by ethnicity and social class) to the respondents as the new girlfriend of their older brother or cousin. In both studies, judgments were assessed by the participants' responses to 45 bipolar adjectives that, in each case, yielded 8 component factors. In both hypothetical contexts, social class was a powerful trigger for a variety of negative expectations: With respect to ethnicity, the Latina women were judged to be more unsuitable for the job of PTO vice president than were the Anglo-Saxon or Jewish women. The authors discussed potential psychological and social consequences of such category-based judgments.     

The efficiency of binding spontaneous trait inferences to actors’ faces

Three experiments tested the hypothesis that the process of binding spontaneous trait inferences (STIs) to actors’ representations is relatively independent of attentional resources. Participants were presented with faces paired with single behaviors. Binding of STIs to actors was revealed by a higher false recognition of implied traits paired with actors’ faces than of implied traits randomly paired with other familiar faces. This effect replicated when each face-behavior pair was presented for 2 s (Experiment 1), when the processing of the information was shallow (Experiment 2), and when participants performed a secondary task during the presentation of behaviors (Experiment 3). Experiment 4 showed that explicit on-line trait judgments of the actor, but not explicit behavior judgments, predicted the false recognition of implied traits in the context of the actor. The possibility that the process of binding STIs to actors’ representations is automatic is discussed.     

Effects of salience and time pressure on ratings of social causality

A model is proposed to account for the effects of a target person's salience on judgments of that target. It is argued that salience leads to more extreme inferences in the direction implied by prior knowledge that is relevant to the judgment. This knowledge may include both specific information about the target being rated and general information about the class of stimuli to which the target belongs. Two experiments supported these hypotheses. When subjects were under time pressure to make judgments of a target person's influence in a social situation, their judgments increased with the salience of the target when they had prior knowledge that the target was generally high in social influence. However, their judgments decreased with the target's salience when subjects had prior knowledge that the target was generally low in social influence. When subjects were given ample time to make their judgments, however, the effects of target salience were attenuated. Possible implications of these findings for prior research on salience effects are discussed.     

Affective guidance of intelligent agents: How emotion controls cognition

How do emotions and moods color cognition? In this article, we examine how such reactions influence both judgments and cognitive performance. We argue that many affective influences are due, not to affective reactions themselves, but to the information they carry about value. The specific kind of influence that occurs depends on the focus of the agent at the time. When making evaluative judgments, for example, an agent’s positive affect may emerge as a positive attitude toward a person or object. But when an agent focuses on a cognitive task, positive affect may act like feedback about the value of one’s approach. As a result, positive affect tends to promote cognitive, relational processes, whereas negative affect tends to inhibit relational processing, resulting in more perceptual, stimulus-specific processing. As a consequence, many textbook phenomena from cognitive psychology occur readily in happy moods, but are inhibited or even absent in sad moods (149).     

"The referents of trait inferences: The impact of trait concepts versus actor-trait links on subsequent judgments": Retraction of Stapel, Koomen, and van der Pligt (1996)

Reports the retraction of "The referents of trait inferences: The impact of trait concepts versus actor-trait links on subsequent judgments" by Diederik A. Stapel, Willem Koomen and Joop van der Pligt (Journal of Personality and Social Psychology, 1996[Mar], Vol 70[3], 437-450). This retraction follows the results of an investigation into the work of Diederik A. Stapel (further information on the investigation can be found here: https://www.commissielevelt.nl/). The Drenth Committee has found evidence of fraud, leading to the conclusion that fraud is most likely in the data supplied by Diederik A. Stapel. His co-authors were unaware of his actions and were not involved in the collection of the likely fraudulent data. (The following abstract of the original article appeared in record 1996-03014-002.) The authors investigated the hypothesis that when trait inferences refer to abstract behavior labels they act as a general interpretation frame and lead to assimilation in subsequent judgments of an ambiguous target, whereas when they refer to a specific actor-trait link they will be used as a scale anchor and lead to contrast. Similar to G. B. Moskowitz and R. J. Roman's (see record 1992-31124-001) study, participants who were instructed to memorize trait-implying sentences showed assimilation, and participants who were instructed to form an impression of the actors in these sentences showed contrast. However, exposure to trait-implying sentences that described actors with real names and were accompanied with photos of the actors resulted in contrast under both memorization and impression instructions (Experiment 1). Furthermore, contrast ensued when trait-implying sentences were accompanied with information that suggested a person attribution, whereas assimilation ensued when that information suggested a situation attribution, independent of processing goals (Experiment 2). These findings are interpreted as support for referent-based explanations of the consequences of trait inferences. (PsycINFO Database Record (c) 2012 APA, all rights reserved).     

Mediation and production deficiencies in children's judgments of morality

This study investigated the influence of intentions and consequences on moral judgments. Children's and adults' production of inferences about an actor's intentions was assessed separately from their use of intentions as mediators of moral judgments. Two hundred and sixteen kindergarten, fourth grade and adult subjects viewed one of four videotaped episodes in which an actor either intentionally or accidentally produced a positive or negative result. Participants received one of two prompts to produce inferences about the actor's intentions or received no prompt. Each subject rated the actor's intent and the good-ness-badness of the actor. Results supported a mediational deficiency explanation for children's objective moral judgments. Both 6- and 10-year-old children made reliable, adult-like inferences of intentions. However, children's moral evaluations were based primarily on objective consequences while adults' evaluations were based primarily on the intentions of the actor. Young children did have intentionality information available, yet even with prompting this information did not mediate their judgments in an adult-like way; suggesting that there may be a period in development during which the child understands and produces subjective inferences but does not use this information as a basis for moral judgments.
