Disposition-based categories: Structure and salience effects on memory

Two experiments investigated whether disposition-based categories influence the retrieval of behaviors related or unrelated to those categories. In Experiment 1, subjects studied a set of behaviors in order to form an impression of a target person. Impression ratings indicated which category had been activated. In an unexpected recognition test, accuracy was better for category-inconsistent information than for category-consistent behaviors. That result suggested that the structure of disposition-based categories includes qualitatively different representations of consistent and inconsistent acts related to the category. In Experiment 2, subjects rated behaviors with reference to a relevant or irrelevant disposition category. In an unexpected recall test, an advantage for category-inconsistent behaviors was found only when the behaviors had been studied from the perspective of the relevant category. It was concluded that categories are not represented in a form analogous to the representation of category-inconsistent behaviors.     

Cross-cultural differences in relationship- and group-based trust

Two experiments explored differences in depersonalized trust (trust toward a relatively unknown target person) across cultures. Based on a recent theoretical framework that postulates predominantly different bases for group behaviors in Western cultures versus Eastern cultures, it was predicted that Americans would tend to trust people primarily based on whether they shared category memberships; however, trust for Japanese was expected to be based on the likelihood of sharing direct or indirect interpersonal links. Results supported these predictions. In both Study 1 (questionnaire study) and Study 2 (online money allocation game), Americans trusted ingroup members more than outgroup members; however, the existence of a potential indirect relationship link increased trust for outgroup members more for Japanese than for Americans. Implications for understanding group processes across cultures are discussed.     

A matter of design: Priming context and person perception

A matter of considerable debate is whether people spontaneously use categorical knowledge (i.e., stereotypes) to guide their interactions with others. Despite initial evidence for the unconditional automaticity of category activation, recent research has identified a range of factors that moderate this process. Extending this line of inquiry, the current investigation explored the extent to which contextual influences—specifically the order in which priming stimuli are presented to participants—may modulate person categorization. Using a standard semantic-priming paradigm to index category and stereotype activation, participants were presented with priming stimuli that were either intermixed or blocked by sex. The results revealed that: (i) category and stereotype activation are moderated by the order in which priming stimuli are presented; and (ii) priming effects decrease monotonically as a function of category repetition. The theoretical implications of these findings are considered.     

Where to look first for an explanation of induction with uncertain categories

Recent research has examined how people predict unobserved features of an object when its category membership is ambiguous. The debate has focused on whether predictions are based solely on information from the most likely category, or whether information from other possible categories is also used. In the present experiment, we compared these category-based approaches with feature conjunction reasoning, where predictions are based on a comparison among exemplars (rather than categories) that share features with a target object. Reasoning strategies were assessed by examining patterns of feature prediction and by using an eye gaze measure of attention during induction. The main findings were (1) the majority of participants used feature conjunction rather than categorical strategies, (2) people predominantly gazed at the exemplars that were most similar to the target object, and (3) although people gazed most at the most probable category to which an object could belong, they also attended to other plausible category alternatives during induction. These findings question the extent to which category-based reasoning is used for induction when category membership is uncertain.     

The cognitive representation of persons and groups and its effect on recall and recognition memory

A conceptualization of the manner in which trait and behavioral information is organized in memory is proposed and applied in predicting both the recall and recognition of information about persons and groups. Three information presentation conditions were considered: (1) Subjects are told to form an impression of a target (person or group) on the basis of the target's behaviors, and are given a trait-based concept of what the target is like before learning about these behaviors. (2) Subjects are told to form an impression of the target, but a general traitbased concept of the target is not induced until after they learn about the target's behaviors. (3) Subjects receive information about the target's behaviors with instructions to remember the information, and only subsequently are told to form an impression and are given more general information about the target's traits. The proposed model accounted for between-condition differences in both the recall and recognition of behaviors that were consistent and inconsistent with a general trait-based concept of the target, and for contingencies of these differences on whether the target was a single person or a group.     

Mentalizing eye contact with a face on a video: Gaze direction does not influence autonomic arousal

Recent research has revealed enhanced autonomic and subjective responses to eye contact only when perceiving another live person. However, these enhanced responses to eye contact are abolished if the viewer believes that the other person is not able to look back at the viewer. We purported to investigate whether this “genuine” eye contact effect can be reproduced with pre‐recorded videos of stimulus persons. Autonomic responses, gaze behavior, and subjective self‐assessments were measured while participants viewed pre‐recorded video persons with direct or averted gaze, imagined that the video person was real, and mentalized that the person could see them or not. Pre‐recorded videos did not evoke similar physiological or subjective eye contact effect as previously observed with live persons, not even when the participants were mentalizing being seen by the person. Gaze tracking results showed, however, increased attention allocation to faces with direct gaze compared to averted gaze directions. The results suggest that elicitation of the physiological arousal in response to genuine eye contact seems to require spontaneous experience of seeing and of being seen by another individual.     

Categorizing others: the dynamics of person construal

A fundamental question in social cognition is whether people categorize others on the basis of the social groups to which they belong. Integrating ideas from related work on face processing, the current research explored the emergence and boundary conditions of person categorization. Using speeded responses to facial stimuli as a marker of category activation, the authors showed in 3 experiments that person categorization: (a) occurs only under active-encoding conditions and (b) does not extend to applicable but task-irrelevant categorical dimensions, but (c) is sensitive to overlap in the perceptual features that support multiple categorical construals. The authors consider the implications of these findings for models of social-cognitive functioning and the component processes that support person perception.     

Visual laterality in the domestic horse (Equus caballus) interacting with humans

Most horses have a side on which they are easier to handle and a direction they favour when working on a circle, and recent studies have suggested a correlation between emotion and visual laterality when horses observe inanimate objects. As such lateralisation could provide important clues regarding the horse’s cognitive processes, we investigated whether horses also show laterality in association with people. We gave horses the choice of entering a chute to left or right, with and without the passive, non-interactive presence of a person unknown to them. The left eye was preferred for scanning under both conditions, but significantly more so when a person was present. Traditionally, riders handle horses only from the left, so we repeated the experiment with horses specifically trained on both sides. Again, there was a consistent preference for left eye scanning in the presence of a person, whether known to the horses or not. We also examined horses interacting with a person, using both traditionally and bilaterally trained horses. Both groups showed left eye preference for viewing the person, regardless of training and test procedure. For those horses tested under both passive and interactive conditions, the left eye was preferred significantly more during interaction. We suggest that most horses prefer to use their left eye for assessment and evaluation, and that there is an emotional aspect to the choice which may be positive or negative, depending on the circumstances. We believe these results have important practical implications and that emotional laterality should be taken into account in training methods.     

The effects of service dogs on social acknowledgments of people in wheelchairs

Able-bodied people often exhibit behaviors that show them to be socially uncomfortable upon encountering a physically disabled stranger. These behaviors include less eye contact, gaze avoidance, greater personal distance, and briefer social interactions. This study examined whether persons in wheelchairs with service dogs receive more frequent social acknowledgement from able-bodied strangers than people in wheelchairs without dogs receive. Behaviors of passersby were recorded by an observer who followed a person in a wheelchair at a distance of 15 to 30 feet. Observations were made in public areas amid pedestrian traffic, areas such as shopping malls and a college campus. The behaviors of passersby to the person in a wheelchair, with or without a service dog, were recorded, including smiles, conversation, touch, gaze aversion, path avoidance, or no response. Results indicated that both smiles and conversations from passersby increased significantly when the dogs were present. These findings suggest that the benefits of service dogs for their owners extend beyond working tasks to include enhanced opportunities for social exchange. The service dogs substantially reduced the tendency of able-bodied people to ignore or avoid the disabled person.     

Learning about what others were doing: verb aspect and attributions of mundane and criminal intent for past actions

Scientists have long been interested in understanding how language shapes the way people relate to others, yet it remains unclear how formal aspects of language influence person perception. We tested whether the attribution of intentionality to a person is influenced by whether the person's behaviors are described as what the person was doing or as what the person did (imperfective vs. perfective aspect). In three experiments, participants who read what a person was doing showed enhanced accessibility of intention-related concepts and attributed more intentionality to the person, compared with participants who read what the person did. This effect of the imperfective aspect was mediated by a more detailed set of imagined actions from which to infer the person's intentions and was found for both mundane and criminal behaviors. Understanding the possible intentions of others is fundamental to social interaction, and our findings show that verb aspect can profoundly influence this process.     

Eye movements do not reflect retrieval processes: limits of the eye-mind hypothesis

Abstract— This research investigated whether eye movements are informative about retrieval processes. Participants learned facts about persons and locations, and the number of facts (fan) learned about each person and location was manipulated. During a subsequent recognition test, participants made more gazes to high-fan facts than to low-fan facts, and gazes to high-fan facts had a longer duration than gazes to low-fan facts. However, there was no relation between the order in which items were fixated and the relative effect of person or location fan. The effect of person and location fan on gaze duration also did not differ with whether it was the person or location being fixated. A model assuming that the process of retrieval is independent of eye movements was successfully fit to the data on the distribution of gaze durations. According to this model, the effect of fan on number of gazes and gaze duration is an artifact of the longer retrieval times for high-fan facts.     

Memory Errors From A Change of Standard: A Lack of Awareness or of Understanding?

Memory errors occur when the context standard that is used when judging target behaviors is different from the category norm standard that is available later when the behaviors are recalled. Is insufficient awareness the reason for this change-of-standard effect? Two kinds of awareness were maximized in each of two studies: (a) awareness of the relation between the judgment and the context - telling subjects to be sure to use the non-target persons for comparison when judging the target person (salience); and (b) awareness at recall of the earlier judgmental context - asking subjects to recall the non-target persons before recalling the target person (reinstatement). Context reinstatement reduced memory errors. But when context reinstatement and salience were combined, the memory errors reappeared. In Study 2, an attempt at debiasing failed. The change-of-standard effect is explained in terms of a "natural" tendency to use the current categorical meaning of a judgment to reconstruct the referent of its past contextualized meaning.     

A conditional approach to dispositional constructs: the local predictability of social behavior

A conditional approach to dispositions is developed in which dispositional constructs are viewed as clusters of if-then propositions. These propositions summarize contingencies between categories of conditions and categories of behavior rather than generalized response tendencies. A fundamental unit for investigating dispositions is therefore the conditional frequency of acts that are central to a given behavior category in circumscribed situations, not the overall frequency of behaviors. In an empirical application of the model, we examine how people's dispositional judgments are linked to extensive observations of targets' behavior in a range of natural social situations. We identify categories of these social situations in which targets' behavior may be best predicted from observers' dispositional judgements, focusing on the domains of aggression and withdrawal. One such category consists of subjectively demanding or stressful situations that tax people's performance competencies. As expected, children judged to be aggressive or withdrawn were variable across situations in dispositionally relevant behaviors, but they diverged into relatively predictable aggressive and withdrawn actions in situations that required the social, self-regulatory, and cognitive competencies they lacked. Implications of the conditional approach for personality assessment and person perception research are considered.     

参照性交流对关系类别间接性学习的促进作用

以大学生为被试,以4特征虚拟外星生物为实验材料,采用类别的间接性学习范式——个人条件和参照条件,及一个无功能条件,通过三个实验任务（功能预测、自由分类和维度选择）,探讨参照性交流范式下关系类别的间接性学习特点。结果发现：类别的间接性学习条件下,自由分类任务中,被试更倾向于选择关系作为类标准;功能预测的关系类别的间接性学习过程中,参照条件下的功能预测成绩显著高于个人条件,这种差异体现在参照惯例形成的学习过程的中后期;关系类别的间接性学习条件下,参照条件下被试的选择性注意水平显著高于个人条件,这种差异主要表现于选择性注意的指向性方面,而不体现于选择性注意的集中性（对无关维度的抑制）方面。     

A boy primed Sue: feature‐based processing and person construal

Everyday social interaction is often dominated by categorical thinking, with generic group‐based knowledge structures guiding people's dealings with others. Noting the important influence that category‐cueing facial features exert during the initial stages of person construal, the current work explored the effects of hair cues on the process and temporal dynamics of sex categorization. Using a standard priming paradigm to index the products of person construal (i.e., categorical and stereotype‐ based knowledge), the results of three experiments revealed that: (i) hair cues alone are sufficient to trigger category and stereotype activation; and (ii) during the early stages of person perception, these cues have the capacity to reverse conventional priming effects and generate errors of categorical assignment (e.g., female faces prime male knowledge). These findings are considered in the context of contemporary accounts of person construal. Copyright © 2006 John Wiley & Sons, Ltd.     

Can harmful intergroup behaviors truly represent the self?: The impact of harmful and prosocial normative behaviors on intra-individual conflict and compartmentalization

This research investigates how group members subjectively feel about their prosocial vs. harmful intergroup behaviors, and whether these behaviors can represent who they are more globally as a person. Three experiments tested how group norms (pro-merit/parity vs. pro-discrimination) and congruence with these norms predicted compartmentalization of these intergroup behaviors in the self and intra-individual conflict. Experiment 1 (N = 122) revealed that participants who conformed to a pro-discrimination norm reported compartmentalizing this behavior to a greater extent than participants who conformed to a pro-merit norm. Experiments 2 (N = 149) and 3 (N = 222) replicated and extended these findings in real and conflictual intergroup settings, also over and above the effect of relevant superordinate norms. Mediated moderation analyses also revealed that following discriminatory norms was associated with more intra-individual conflict, and that this conflict in turn predicted higher compartmentalization.     

Twelve-Month-Old Infants Generalize Novel Signed Labels,but Not Preferences Across Individuals

By the end of the 1st year, infants expect spoken labels to be extended across individuals and thus seem to understand words as shared conventional forms. However, it is unknown whether infants' willingness to extend labels across individuals is constrained to familiar forms, such as spoken words, or whether infants can identify a broader range of symbols as potential conventions. The present study tested whether 12-month-old infants will extend a novel sign label to a new person. Results indicate that 12-month-olds expect signed object–label relations to extend across agents but restrict object preferences to individuals. The results suggest that infants' expectations about conventional behaviors and linguistic forms are likely broad at 12 months. The implications of these findings for infants' early conceptions of conventional behaviors as well as our understanding of the initial state of the learner are considered.     

The Liking-Similarity Effect: Perceptions of Similarity as a Function of Liking

In these two studies, we examined whether the inferences people make about likable and dislikable targets align with the predictions of balance theory. We hypothesized that people exhibit a liking-similarity effect by perceiving greater similarity with a likable person than a dislikable person. To test this hypothesis, we manipulated the likability of a target person and then assessed participants’ perceptions of similarity to that target person. In both studies, people rated likable others as more similar to themselves than dislikable others across a variety of domains (e.g., attitudes, personality characteristics, behaviors). In Study 2, individual differences in self-concept clarity, self-esteem, and preference for consistency moderated the liking-similarity effect.
