Nonverbal communication of affect in interracial dyads.

Two experiments investigated the relationship between nonverbal behavior and the racial composition of a teacher–student dyad. The Multifactor Racial Attitude Inventory was used to measure prejudice. In Exp I, 36 high- and low-prejudiced White female undergraduates, acting as teachers, were led to praise successful White and Black students (confederates). Analysis of samples of nonverbal behavior showed that high-prejudiced teachers nonverbally discriminated between White and Black students (favoring Whites) significantly more than low-prejudiced teachers. In Exp II, 40 White and Black teachers (female undergraduates) taught successful White and Black students (confederates). Results show that both Whites and Blacks behaved nonverbally more positively to a student of their own race than to a student of the other race, although only same-race judges (12 White female undergraduates) could distinguish the differences in affect displayed by the Ss.

Story recall in young Black and White children: Effects of racial group membership, race of experimenter, and dialect.

Tested the effects of racial group membership, race of E, and dialect on unstructured and probed recall. l6 Black and 16 White 4-6 mo old children were Ss. Subgroups of 4 Ss within each racial group were randomly assigned to the experimental conditions such that order of exposure to E (Black and White) and dialects Standard English vs Black English vernacular) were counterbalanced. Results show that Whites performed better than Blacks in Standard English, Blacks performed better than Whites in Black English vernacular, Blacks tested in Black English vernacular were equivalent to Whites tested in Standard English, and Whites performed better in Standard English than in Black English vernacular. When probed with questions, there was an overall increase in the proportion of correct information for both racial groups. (15 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of racial similarity and interviewer intimacy in a peer counseling analogue.

The effects of the intimacy of an interviewer's disclosure and the racial composition of a dyad on interviewees' liking for an interviewer, impressions of the interviewer, and subsequent self-disclosure were examined in a peer counseling analogue. We predicted and found that intimate disclosure by an interviewer is especially useful in eliciting self-disclosure from Black subjects. Furthermore, we predicted and found that differences in liking for and impressions of intimate and nonintimate interviewers would be particularly pronounced in those dyads in which the interviewer was White and the interviewee was Black with greater liking for and more positive impressions of the intimately disclosing interviewer. We discuss the implications of these results for the reported tendency for Blacks to terminate counseling prematurely and to disclose less than Whites in counseling.

WISC-R subscale patterns of abilities of Blacks and Whites matched on Full Scale IQ.

270 Black and 270 White children (ages 6–16.5 yrs) drawn from the national stratified random sample used in the standardization of the WISC-R were matched on age, sex, and WISC-R Full-Scale IQ to facilitate investigation of the patterns of specific cognitive abilities, as measured by the 12 subtests of the WISC-R, between the 2 racial groups. Multivariate analysis of the patterns of subtest differences between Whites and Blacks and group comparisons on 3 orthogonalized factor scores (Verbal, Performance, Memory) showed small but reliable average White–Black differences in patterns of ability. The IQ-matched racial groups showed no significant difference on the Verbal factor; Whites exceeded Blacks on the Performance (largely spatial visualization) factor; Blacks exceeded Whites on the Memory factor.

Metoprolol metabolism via cytochrome P4502D6 in ethnic populations

OBJECTIVE: The objective of this study was to determine whether metabolism via cytochrome P4502D6 (CYP2D6) was higher in Black subjects than White subjects. METHODS: Ten Black and 10 White healthy male volunteers who were phenotyped CYP2D6 extensive metabolizer phenotypes participated in this randomized, cross-over study in which metoprolol was used as a model CYP2D6 substrate. In both study phases, subjects received oral rac-metoprolol tartrate (200 mg); during one phase, subjects also took quinidine sulfate (100 mg) daily beginning 3 days before the dose of metoprolol. Plasma samples were collected for 12 and 24 hr after the dose in the metoprolol and metoprolol plus quinidine phases, respectively. Metoprolol enantiomer concentrations were determined by chiral HPLC with fluorescence detection. RESULTS: S-metoprolol areas under the concentration vs. time curves during the metoprolol phase were 879 +/- 600 ng/ml*hr in White subjects vs. 984 +/- 653 ng/ml*hr in Black subjects. During inhibition of CYP2D6-mediated metabolism with quinidine, S-metoprolol areas under the concentration vs. time curves were 2515 +/- 749 and 2719 +/- 742 in White and Black subjects, respectively. Metoprolol elimination half-lives in both groups were approximately doubled by quinidine. Mean S-metoprolol/R-metoprolol ratios were 1.39 in both racial groups during the metoprolol phase, and during the metoprolol plus quinidine phase were 0.89 and 1.03 in White subjects and Black subjects, respectively (p < 0.05, Blacks vs. Whites). The percentage of metoprolol metabolism inhibited by quinidine was similar between Blacks and Whites (e.g., 66 +/- 15% and 64 +/- 25% of S-metoprolol apparent oral clearance in Blacks and Whites, respectively). CONCLUSIONS: We conclude that there are no differences between Black subjects and White subjects in metabolism via CYP2D6. There were also no racial differences in the contribution of CYP2D6 to overall metoprolol metabolism. The results of this study suggest that drugs are primarily metabolized by CYP2D6 will not exhibit racial differences in their disposition.     

Evaluative race–class stereotypes by race and perceived class of subjects.

80 Black and 74 White college students assigned traits, from a list of 80, to the Black lower class, Black middle class, White lower class, and White middle class. Each S rated the 5 or fewer traits that he or she had chosen as being most typical of the respective race–class groups from –5 (unfavorable) to +5 (favorable) for the given groups. Ss also assigned themselves to 1 of 4 classes: lower class, working class, middle class, or upper class. On the basis of these judgments, the Ss within each racial group were classified as perceiving themselves to be above or below the median of their own race's distribution. White Ss assigned more favorable characteristics to the middle than to the lower class and did not rate Blacks lower than Whites. Black Ss made a similar, but smaller, social class distinction and, in addition, generally perceived Blacks more favorably than Whites.

Polarized appraisals of out-group members.

Developed and tested a model that assumes that people have a more complex schema regarding in-groups than out-groups and consequently, that appraisals of out-group members will be more extreme or polarized than appraisals of in-group members. Four experiments with 415 White male and female undergraduates tested this model, as well as predictions derived from attribution principles. In Exp I, Ss read and evaluated a law school application containing incidental information about the applicant's race and gender. A Black applicant with strong credentials was judged more favorably than an identical White applicant, supporting a prediction derived from the augmentation principle. In Exp II, an applicant with weak credentials was included in the design. Results support the prediction that out-group members would be evaluated more extremely: When the application credentials were positive, the out-group member (a Black or opposite-sex applicant) was evaluated more favorably than the in-group member (a White or same-sex applicant). When the application credentials were weak, the out-group member was evaluated more negatively. Exp III and IV provided support for the 2 assumptions underlying the complexity–extremity hypothesis: First, White Ss demonstrated greater complexity regarding Whites than Blacks. Second, greater complexity resulted in evaluative moderation. (20 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The modern face of prejudice and structural features that moderate the effect of cooperation on affect

Facial muscle activity and self-reports were examined for racial bias in 3 studies. In the first 2 experiments, While participants imagined cooperating with a Black or White partner. Experiment 1 manipulated reward structure in the context of cooperating with a deficient partner. Experiment 2 manipulated partner deficiency and willingness to expend compensatory effort. On both facial EMG and self-report measures, joint rewards produced more negative affect than independent rewards. However, all partners were liked more when they were willing to try to compensate for their deficits. In addition, more liking was reported for Black partners, but EMG activity indicated bias against Blacks. Experiment 3 investigated individual differences in prejudice. Again, a greater preference for Blacks than Whites occurred on self-report measures, but in their facial muscle activity, high-prejudiced participants exhibited bias against Blacks.     

The prevalence and 3-year incidence of dementia in older Black and White community residents

OBJECTIVE: To determine the prevalence and 3-year incidence of dementia in Blacks and Whites age 65 and older in a five-county Piedmont area of North Carolina. DESIGN: Stratified random sample of members of the Duke Established Populations for Epidemiologic Studies of the Elderly (EPESE) (baseline n = 4,136; 55% Black; weighted n = 28,000). Prevalence study members were differentially selected on the basis of score on the Short Portable Mental Status Questionnaire at the second in-person Duke EPESE wave. Incidence study members included all persons with obvious cognitive decline over a 3-year period, and a 10% sample of the remainder. MEASUREMENTS: Self- and informant report on health history, functional status, and memory. Consortium to Establish a Registry for Alzheimer's Disease (CERAD) Neuropsychology Battery administered to all subjects, and CERAD Clinical Battery to those with impaired memory. Clinical consensus to determine presence and type of dementia. RESULTS: Prevalence of dementia for persons > or =68 years old was 0.070 (95% confidence interval = 0.021-0.119) for Blacks and 0.072 (0.022-0.122) for Whites. Rates for Black men (0.078, 0.001-0.155) exceeded those for Black women (0.066, 0.003-0.129), but gender rates for Whites were reversed (men: 0.044, 0.000-0.103), (women: 0.087, 0.015-0.160). Neither race nor gender differences were significant. Prevalence of dementia increased through age 84 and tapered off thereafter. Three-year incidence of dementia was 0.058 (0.026-0.090) for Blacks and 0.062 (0.027-0.097) for Whites. Neither race nor gender differences were significant. Incidence increased through age 84, but moderated thereafter for all but Black men. The proportional representation of different types of dementia varied little by race. CONCLUSION: Prevalence, 3-year incidence, and types of dementia are comparable in Black and White elderly in the Piedmont area of North Carolina.     

Relationship between scholastic aptitude, perception of university climate, and college success for Black and White students.

Computed, in racial subgroups, the correlations of university climate and Scholastic Aptitude Test (SAT) scores with 2 criteria of academic success--GPA and students' estimated probability of receiving a degree. Factor analyses of a 115-item university climate questionnaire were performed separately for samples of 138 Black and 550 White college students. SAT scores were significantly related to GPA for both Blacks and Whites, although they were not related to Ss' estimated probability of recieving a degree in either racial group. Some university climate scales were significantly related to the 2 criteria. Viewing the university in a positive way was associated (a) with high criterion scores for Whites and with low criterion scores for Blacks, and (b) with high SAT scores for Whites and low SAT scores for Blacks. Although GPA was significantly correlated with estimated probability of degree in both Black and White samples, the correlation was significantly higher in the Black sample.

Expectations and preferences for counselor race and their relation to intermediate treatment outcomes.

The expectations and preferences of 26 White and 8 Black male veterans for the race of their counselor were investigated at the time the clients entered treatment in a midwestern outpatient mental health clinic. In addition, Ss' satisfaction with treatment, measured by a 3-factor self-rating scale and dropout status, were analyzed in relation to Ss' expectations and preferences for counselor race and the racial makeup of the treatment dyad. Results indicate that White and Black clients alike expected their counselor to be White. About half of the White Ss and half of the Blacks indicated that they had no preferences. However, the significant association between race and S preference for counselor race suggests that Ss expressing preferences preferred counselors of their own race. Dropout and satisfaction with treatment were not related to the nature of Ss' racial expectations and preferences or to the racial makeup of the treatment dyads.

Feedback to minorities: evidence of a positive bias

This research tested the prediction that Whites supply more lenient feedback to Blacks than to fellow Whites. In Study 1, White undergraduates were led to believe that they were giving feedback on essays written by either a Black or a White fellow student. As predicted, feedback was less critical when the supposed feedback recipient was Black rather than White. It was also predicted that the feedback bias would be selective for subjective evaluative domains (i.e., essay content) in contrast to objective evaluative domains (i.e., essay mechanics). An interaction between recipient race and evaluative domain confirmed this prediction. The domain-specific quality of the feedback bias suggests that the bias may arise from social motives rather than from more automatic processes. Study 2 replicated these results.     

Effects of social behavior on interracial acceptance.

To test children's use of race and social behavior as cues in social acceptance, 128 Black and White male kindergartners and 1st graders rated 6 unknown videotaped target children for likability. Targets varied factorially on race (Black or White) and exhibited either positive, negative, or neutral classroom social behavior. Across age, socioeconomic status, and race, Ss used behavior as a cue, accounting for 50% of likability variance. Positive targets were liked equivalently, but Black neutral and negative targets were liked less than White counterparts. Racial but not socioeconomic status differences in the use of behaviors as social cues were found. Negative targets were liked more by Blacks than Whites and neutral targets were liked more by Whites than Blacks. (9 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Implicit and explicit prejudice and interracial interaction.

The present research examined how implicit racial associations and explicit racial attitudes of Whites relate to behaviors and impressions in interracial interactions. Specifically, the authors examined how response latency and self-report measures predicted bias and perceptions of bias in verbal and nonverbal behavior exhibited by Whites while they interacted with a Black partner. As predicted, Whites' self-reported racial attitudes significantly predicted bias in their verbal behavior to Black relative to White confederates. Furthermore, these explicit attitudes predicted how much friendlier Whites felt that they behaved toward White than Black partners. In contrast, the response latency measure significantly predicted Whites' nonverbal friendliness and the extent to which the confederates and observers perceived bias in the participants' friendliness.

"Their ideas of beauty are, on the whole, the same as ours": Consistency and variability in the cross-cultural perception of female physical attractiveness.

The consistency of physical attractiveness ratings across cultural groups was examined. In Study 1, recently arrived native Asian and Hispanic students and White Americans rated the attractiveness of Asian, Hispanic, Black, and White photographed women. The mean correlation between groups in attractiveness ratings was r?=?.93. Asians, Hispanics, and Whites were equally influenced by many facial features, but Asians were less influenced by some sexual maturity and expressive features. In Study 2, Taiwanese attractiveness ratings correlated with prior Asian, Hispanic, and American ratings, mean r?=?.91. Supporting Study 1, the Taiwanese also were less positively influenced by certain sexual maturity and expressive features. Exposure to Western media did not influence attractiveness ratings in either study. In Study 3, Black and White American men rated the attractiveness of Black female facial photos and body types. Mean facial attractiveness ratings were highly correlated (r?=?.94), but as predicted Blacks and Whites varied in judging bodies. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

White–Black achievement differences: The narrowing gap.

Discusses findings from the National Assessment of Educational Progress and the College Entrance Examination Board that demonstrate consistent reductions during recent years in the size of average achievement differences between White and Black elementary and secondary school students. Societal changes that may have contributed to increasing the average achievement levels for Black students (e.g., desegregation) are examined, and it is noted that these trends are not necessarily due to the effects of educational and social programs designed toward this end. It is argued that the difference in enrollment levels for high school algebra and geometry courses between predominantly White schools and predominantly Black schools accounts for part of the average White–Black difference in 17-yr-olds' mathematics achievement scores. Further, if average enrollments in mathematics courses for Blacks became more similar to average enrollments for Whites, White–Black average mathematics achievement differences might be reduced further.

Stereotype threat in criminal interrogations: Why innocent Black suspects are at risk for confessing falsely.

Little theoretical attention has been paid to evidence that Blacks are overrepresented in samples of false confessors compared to Whites. One possible explanation is that innocent Black suspects experience stereotype threat in interrogations and that this threat causes Black suspects to experience more arousal, self-regulatory efforts, and cognitive load compared to White suspects. These psychological mechanisms could lead innocent Black suspects to display more nonverbal behaviors associated with deception and, ironically, increase the likelihood that police investigators perceive them as guilty. In response, investigators might engage in more coercive tactics and exert more pressure to confess on Black suspects than White suspects. This could increase the need to escape interrogation and the likelihood of doing so by confessing falsely more for Blacks than for Whites. I present these hypotheses within a social psychological framework, and discuss future directions for testing the model and theoretical and practical implications of such work.

Multiple myeloma among Blacks and Whites in the United States: role of cigarettes and alcoholic beverages

In the United States, the incidence rates of multiple myeloma in Blacks are more than twice those in Whites, but the etiology of this cancer is poorly understood. A population-based case-control interview study of 571 subjects (365 White, 206 Black) with multiple myeloma and 2,122 controls (1,155 White, 967 Black) living in three areas of the United States (Georgia, Michigan, New Jersey) offered the opportunity to investigate the relationship with smoking and alcohol drinking and to evaluate whether these factors might contribute to the excess risk of multiple myeloma in Blacks. For Blacks and Whites of either gender, there were no significantly elevated risks associated with ever use of cigarettes or alcoholic beverages and no consistent patterns with either intensity or duration of use. These data support previous studies indicating that smoking and drinking are not related causally to the risk of multiple myeloma, and thus cannot account for the racial disparity in incidence rates.     

Clinical comparison of Black and White suicide attempters.

Compared clinical characteristics of Black and White suicide attempters. The sample consisted of virtually all (N?=?275) attempters aged 16 yrs and older brought to the Emergency Unit of the Yale-New Haven Hospital over a 1-yr period (1971–1972). Clinical ratings were made by on-duty resident psychiatrists using 42 variables dealing with mood, motivation, etc. Statistical analysis revealed few differences in Black and White profiles, a result contrary to theories asserting that Black psychology requires different principles from that of White psychology. A related incidental finding was that the frequency of suicide attempts appeared to be about the same among Blacks and Whites, which discredits the widely held belief that suicide is not an important psychiatric problem among Blacks. Rating areas in which the 2 groups did differ somewhat included extent of motivation to influence others, feelings of depression (hopelessness), and deliberateness of planning the attempt. In each of these areas, White attempters had higher scores. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
