The role of diagnosticity in stereotype formation: Perceiving group means and variances.

Three experiments tested the hypotheses that while forming stereotypes of social groups, people abstract the central tendency and variability of different attribute dimensions to determine which ones best differentiate the groups and that more differentiating dimensions are more likely to become stereotypical in the sense of becoming strongly associated with the groups in memory. Supporting these hypotheses, Exp 1 found that, after viewing behaviors performed by members of 2 groups, Ss characterized the groups more in terms of attribute dimensions indicating larger differences between the central tendencies of the groups, and Exp 2 showed that this effect did not occur when Ss formed impressions of only 1 group. Exp 3 found that Ss also characterized groups more in terms of attribute dimensions indicating lower within-group variability. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Perceived entitativity, stereotype formation, and the interchangeability of group members.

The authors investigated the effects of perceived entitativity of a group on the processing of behavioral information about individual group members and the extent to which such information was transferred to other group members. The results of 3 experiments using a savings-in-relearning paradigm showed that trait inferences about a group member, based on that member's behavior, were stronger for low entitative groups and for collections of individuals. However, the transference of traits from 1 group member to other members of the group was stronger for high entitative groups. These results provide strong evidence that the perception of high entitativity involves the abstraction of a stereotype of the group and the transfer of that stereotype across all group members. Implications for group impression formation and stereotyping are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Perspective-taking: Decreasing stereotype expression, stereotype accessibility, and in-group favoritism.

Using 3 experiments, the authors explored the role of perspective-taking in debiasing social thought. In the 1st 2 experiments, perspective-taking was contrasted with stereotype suppression as a possible strategy for achieving stereotype control. In Experiment 1, perspective-taking decreased stereotypic biases on both a conscious and a nonconscious task. In Experiment 2, perspective-taking led to both decreased stereotyping and increased overlap between representations of the self and representations of the elderly, suggesting activation and application of the self-concept in judgments of the elderly. In Experiment 3, perspective-taking reduced evidence of in-group bias in the minimal group paradigm by increasing evaluations of the out-group. The role of self- other overlap in producing prosocial outcomes and the separation of the conscious, explicit effects from the nonconscious, implicit effects of perspective-taking are discussed.

Attentional processes in stereotype formation: A common model for category accentuation and illusory correlation.

Stereotype formation may be based on the exaggeration of real group differences (category accentuation) or the misperception of group differences that do not exist (illusory correlation). This research sought to account for both phenomena with J. K. Kruschke's (1996, 2001, 2003) attention theory of category learning. According to the model, the features of majority groups are learned earlier than the features of minority groups. In turn, the features that become associated with a minority are those that most distinguish it from the majority. This second process is driven by an attention-shifting mechanism that directs attention toward group-attribute pairings that facilitate differentiation of the two groups and may lead to the formation of stronger minority stereotypes. Five experiments supported this model as a common account for category accentuation and distinctiveness-based illusory correlation. Implications for the natures of stereotype formation, illusory correlation, and impression formation are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Group impressions as dynamic configurations: The tensor product model of group impression formation and change.

Group impressions are dynamic configurations. The tensor product model (TPM), a connectionist model of memory and learning, is used to describe the process of group impression formation and change, emphasizing the structured and contextualized nature of group impressions and the dynamic evolution of group impressions over time. TPM is first shown to be consistent with algebraic models of social judgment (the weighted averaging model; N. Anderson, 1981) and exemplar-based social category learning (the context model; E. R. Smith & M. A. Zárate, 1992), providing a theoretical reduction of the algebraic models to the present connectionist framework. TPM is then shown to describe a common process that underlies both formation and change of group impressions despite the often-made assumption that they constitute different psychological processes. In particular, various time-dependent properties of both group impression formation (e.g., time variability, response dependency, and order effects in impression judgments) and change (e.g., stereotype change and group accentuation) are explained, demonstrating a hidden unity beneath the diverse array of empirical findings. Implications of the model for conceptualizing stereotype formation and change are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Illusory correlation and social categorization: Toward an integration of motivational and cognitive factors in stereotype formation.

Investigated the effect of group membership on the processes underlying the formation of group stereotypes. In two studies, Ss were randomly assigned to a majority group, a minority group, or neither group (control). Ss were then presented with 48 short statements in which other in-group and out-group members displayed disirable and undesirable behaviors, with either desirable or undesirable behaviors occurring more frequently. Across these items there was no correlation between group membership and desirability of behavior. In Study 1, measures of covariation perception showed that control Ss formed biased impressions of the group, consistent with a memory-based process of stereotype formation. Group members' perceptions showed little evidence of this bias. In Study 2, group members showed evidence of an in-group bias, with further evidence suggesting that these biased judgments were not dependent upon memory processes. Discussion focuses on the complexity of stereotyping processes introduced by social categorization. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The stereotype of the computer scientist.

Explored the extent and nature of the characterizations applied uniquely to computer scientists by 436 undergraduate psychology students (aged 17–60 yrs) and 74 undergraduate computer science students (aged 20–24 yrs) within the stereotyped paradigm. The Adjective Checklist was used for assessing stereotypes. It was found that Ss tended to stereotype computer scientists along 2 dimensions: technological dedication and sociability. Characterizations by computer science students did not differ greatly from those of the general population; however, they did not typify themselves, as prospective computer scientists, as personally fulfilling an unsociability stereotype. Computer science respondents described themselves as more outgoing and interested in the people around them than they perceived most of the other computer scientists to be.

Individuality and group formation: The role of independence and differentiation.

This research examined the interplay of group formation and individualization processes with a particular emphasis on minority and majority groups. First, a 2-component theory of individuality that distinguishes between individuality as independence and as differentiation from other people was presented, tested, and cross-validated in 2 questionnaire studies. Next, a pilot experiment provided first support for the working assumption that the salience of the differentiation or independence components of individuality differentially affect minority and majority group formation. Finally, the main experiment demonstrated that these individuality effects on minority and majority group formation are due largely to a differential orientation toward either intergroup or intragroup comparisons. This experiment also uncovered a unique effect of relative in-group size, but this effect was limited to similarity-based group formation.

Battle of the sexes: Gender stereotype confirmation and reactance in negotiations.

The authors examined how gender stereotypes affect negotiation performance. Men outperformed women when the negotiation was perceived as diagnostic of ability (Experiment 1) or the negotiation was linked to gender-specific traits (Experiment 2), suggesting the threat of negative stereotype confirmation hurt women's performance relative to men. The authors hypothesized that men and women confirm gender stereotypes when they are activated implicitly, but when stereotypes are explicitly activated, people exhibit stereotype reactance, or the tendency to behave in a manner inconsistent with a stereotype. Experiment 3 confirmed this hypothesis. In Experiment 4, the authors examined the cognitive processes involved in stereotype reactance and the conditions under which cooperative behaviors between men and women can be promoted at the bargaining table (by activating a shared identity that transcends gender).

The Negro stereotype and perceptual accentuation.

3 hypotheses were tested: (1) There is no difference in the degree of personality stereotyping of Negro photographs varying widely in physiognomic Negroidness; (2) Anti-Negro judges exaggerate the personality stereotype of Negroes, whereas pro-Negro judges de-emphasize it; and (3) Both anti- and pro-Negro judges perceive the Negro as more Negroid in physiognomic traits than do neutral judges. The first 2 hypotheses were supported by the data. Although a comparison of the mean Negroidness scores for the 3 groups of judges supported the third hypothesis, the difference between the neutral group and the pro-Negro group was not statistically significant.

A note on the independence of stereotype and attitude.

Presented 43 attitude statements and 14 evaluative and 10 stereotypic bipolar trait-adjectives concerning French-Canadians to 67 male and 94 female Manitoba undergraduates. The 1st-order factor analysis produced a separation of the 3 measures, resulting in 3 attitude factors, an evaluative trait-adjective factor, and a stereotype factor. A 2nd-order factor analysis of the relations among primary factors resulted in 2 factors: (a) a general evaluative factor comprising the evaluative trait-adjective dimension and the 3 attitude dimensions from the 1st-order analysis, and (b) a factor clearly defined by the stereotype dimension. Implications of the present findings of relative independence of stereotype and attitude are discussed in relation to traditional methods of defining and assessing stereotypes.

Attribution, the attractiveness stereotype, and the elderly.

The applicability of the physical attractiveness stereotype to perceptions of the elderly was tested in two studies. In the first study, college age and old observers rated the physical attractiveness of faces of elderly people (age 60–93). On the basis of these ratings, faces at three distinct levels of attractiveness were selected for use in the second study. In the second study, 72 young adult and 72 old volunteers viewed the selected faces and rated them in three areas of perceived social characteristics: personality factors, success in life experiences, and occupational achievements. The typical physical attractiveness stereotype was found for both groups of observers and in each of three areas of judgment. Multivariate analyses of variance for linear trends showed higher favorability of perceived social characteristics for faces with high perceived physical attractiveness.

Development and differentiation of glial precursor cells in the rat cerebellum

The development and differentiation of bipotential glial precursor cells has been studied extensively in tissue culture, but little is known about the distribution and fate of these cells within intact animals. To analyze the development of glial progenitor cells in the developing rat cerebellum, we utilized immunofluorescent, immunocytochemical, and autoradiographic techniques. Glial progenitor cells were identified with antibodies against the NG2 chondroitin-sulfate proteoglycan, a cell-surface antigen of 02A progenitor cells in vitro, and the distribution of this marker antigen was compared to that of marker antigens that identify immature astrocytes, mature astrocytes, oligodendrocyte precursors, and mature oligodendrocytes. Cells expressing the NG2 antigen appeared in the cerebellum during the last 3-4 days of embryonic life. Over the first 10 days of postnatal life, the NG2-labeled cells incorporated 3H-thymidine into their nuclei and their total number increased. At all ages examined, the NG2-labeled cells did not contain either vimentin-like or glial fibrillary acidic protein (GFAP)-like immunoreactivity, suggesting that they do not develop along an astrocytic pathway. NG2-labeled cells of embryonic animals expressed GD3 ganglioside antigens, a property of oligodendrocyte precursors, whereas NG2-positive cells of postnatal animals did not express GD3 immunoreactivity. Nevertheless, the NG2-labeled cells of the nascent white matter expressed oligodendrocyte-specific marker antigens. Cells lying outside of the white matter continued to express the NG2 antigen. In adult animals, the NG2-labeled cells incorporated 3H-thymidine. Glial cells isolated from adult animals and grown in tissue culture express the NG2 antigen and display the phenotypic plasticity characteristic of 02A progenitor cells. These findings demonstrate that a population of glial progenitor cells is extensive within both young and adult animals.     

Marketing your product: The psychologist as communicator.

A questionnaire on the importance of different types of communication materials was sent to 60 persons who had requested from Boys Town material concerning the psychologically oriented teaching-family model of residential treatment. Ss, divided into 4 groups on the basis of their familiarity with the program, generally ranked how-to books and videotapes as more important than more traditional means of communication such as journal articles and textbook chapters. Results are discussed in terms of the need for nonacademic psychologists to learn new communication approaches. (6 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Automatic and controlled processes in stereotype priming.

The experiments in this article were conducted to observe the automatic activation of gender stereotypes and to assess theoretically specified conditions under which such stereotype priming may be moderated. Across 4 experiments, 3 patterns of data were observed: (1) evidence of stereotype priming under baseline conditions of intention and high cognitive constraints; (2) significant reduction of stereotype priming when a counterstereotype intention was formed even though cognitive constraints were high; and (3) complete reversal of stereotype priming when a counterstereotype intention was formed and cognitive constraints were low. These data support proposals that stereotypes may be automatically activated, as well as proposals that perceivers can control and even eliminate such effects.

Stereotype performance boosts: The impact of self-relevance and the manner of stereotype activation.

The activation of positive stereotypes has been shown to produce academic performance boosts. Evidence regarding the role of self-relevance in producing such effects has been mixed. The authors propose that the subtlety of stereotype activation plays a key role in creating performance boosts among targets and nontargets of stereotypes. Study 1 found that subtle stereotype activation boosted performance in targets, but blatant activation did not. Study 2 was conducted on both targets and nontargets using different methods of stereotype activation. Again, targets showed performance boosts when stereotypes were subtly activated but not when they were blatantly activated. Nontargets, however, showed boosts in performance only when stereotypes were blatantly activated. The role of self-relevance in mediating sensitivity to stimuli is discussed.

Limitations in generalizability of the physical attractiveness stereotype: The self-esteem exception.

Previous research has reported the existence of a physical attractiveness stereotype which results in several generalized assumptions about physically attractive individuals. Included in these assumptions is that physically attractive individuals are more capable on a number of dimensions and possess more socially desirable personality traits than less attractive individuals. It was predicted that self-esteem would interfere with the attractiveness stereotype in that low self-esteem (LSE) Ss would (a) denigrate an attractive other more than high self-esteem (HSE) Ss, (b) denigrate an attractive person more than an unattractive person, and (c) perceive greater situational similarity with an unattractive than attractive other, with HSE Ss perceiving the reverse. 80 female Ss designated either high or low in self-esteem, based on their scores on the Rosenberg Self-Esteem Scale, evaluated either an attractive or unattractive stimulus person who had socially transgressed. Results indicate that, as predicted, LSE Ss tended to denigrate a transgressing attractive other more than HSE Ss. Although insignificant, the 2nd hypothesis was in the predicted direction in that LSE Ss judged a social transgression to be reflective of personality deficits more for the attractive than unattractive stimulus person. Situational similarity results were in accordance with predictions. (French summary) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Intimations of mortality: Integrative simplification as a precursor of death.

Tested the hypothesis that a "terminal drop" in cognitive functioning occurs a few years prior to death. Letters written during the last 10 yrs of life were selected from the published correspondence of 18 eminent individuals (such as Freud and Napoleon) and scored for integrative complexity—a variable related to the degree of integration and differentiation in information processing. The overall analysis supported the terminal drop hypothesis. The predicted decline in complexity was found during the 5 yrs prior to death among Ss who died of protracted illness or old age but only in the year immediately prior to death among Ss who died suddenly. There was no relation between complexity and age, and the mean complexity scores of men were higher than those of women. (13 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Mere effort and stereotype threat performance effects.

Although the fact that stereotype threat impacts performance is well established, the underlying process(es) is(are) not clear. Recently, T. Schmader and M. Johns (2003) argued for a working memory interference account, which proposes that performance suffers because cognitive resources are expended on processing information associated with negative stereotypes. The antisaccade task provides a vehicle to test this account because optimal performance requires working memory resources to inhibit the tendency to look at an irrelevant, peripheral cue (the prepotent response) and to generate volitional saccades to the target. If stereotype threat occupies working memory resources, then the ability to inhibit the prepotent response and to launch volitional saccades will be impaired, and performance will suffer. In contrast, S. Harkins's (2006) mere effort account argues that stereotype threat participants are motivated to perform well, which potentiates the prepotent response, but also leads to efforts to counter this tendency if participants recognize that the response is incorrect, know the correct response, and have the opportunity to make it. Results from 4 experiments support the mere effort but not the working memory interference account. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The traditional–liberated woman dimension: Social stereotype and self-concept.

Two scales were derived from the Adjective Check List to measure traits associated with traditional–liberated dimension for women: The Traditional–Liberated Social Stereotype Scale and the Traditional–Liberated Self-Concept Scale. Two samples of women (N?=?373 17–67 yr olds) were used to develop the scales. Results show that both scales have acceptable reliability and validity but are only modestly related to one another.
