The Formation of Attitudes Toward New Immigrant Groups1

People often receive information about new immigrant groups prior to any direct contact with group members. However, it is not clear how this information shapes attitudes toward the groups. To explore this issue, 204 subjects were told about an unknown immigrant group that was presented as high or low in personal relevance. Subjects were then given positive or negative consensus information about the emotions that group members elicit from others, group members' personality traits, and group members' values. As expected, results indicated that the presentation of positive information about emotional reactions, personality traits, and values caused attitudes to be more favorable than did the presentation of negative information. Importantly, however, the combined impact of the emotion and personality trait information depended on whether the group was perceived to be of high or low personal relevance. Specifically, when the information about emotions and personality traits was similarly valanced (i.e., both were positive or both were negative), attitudes toward the group tended to be less favorable in the high personal relevance condition than in the low personal relevance condition. In contrast, when mixed information was presented (i.e., positive emotions and negative personality traits or negative emotions and positive personality traits), attitudes tended to be more favorable in the high personal relevance condition. In addition, attitudes, once formed, predicted further perceptions of the group and behavioral intentions toward group members. The implications of the findings for the reduction of prejudice toward new immigrant groups are discussed.     

Adolescent Males' Knowledge and Attitudes About AIDS in The Context of Their Social World1

This study sought to find out how much total knowledge adolescents had concerning AIDS, what particular areas of knowledge were deficient, and how those areas might be related to attitudes and experiences in their social world. Seventy-eight adolescent males from one suburban and three urban high schools were interviewed. A 101-item questionnaire was used to assess: a) overall knowledge about AIDS; b) attitudes about sexuality, drugs, death, and AIDS and; c) related aspects of their social world, i.e., number of IV drug users known, and sources of information about AIDS. Analyses of variance were performed on overall knowledge of AIDS and on five content areas of knowledge. Race was shown to relate to significant differences in the knowledge scores. The social world associated with the urban samples were discussed as risk factors for minority youth. Different attitudes related to strengths and weaknesses in different areas of knowledge. Attitudes associated with deficiencies in different subareas of knowledge were discussed as additional risk factors and as presenting target areas for AIDS education efforts.     

HIGH SCHOOL DRIVER EDUCATION USING PEER TUTORS,DIRECT INSTRUCTION,AND PRECISION TEACHING

The authors investigated the combined effects of direct instruction and precision teaching by peer tutors in a high school driver education curriculum. Learners (N = 4) included students with intellectual and learning disabilities and students without disabilities. Peer tutoring was associated with immediate increases in correct responding and a simultaneous and rapid deceleration of errors. Three learners passed the written tests in the driver education classroom, obtained driver's licenses, and produced similar or better driving records than students who did not require assistance. This program is being continued and expanded by school personnel without assistance from the authors.

Breast Cancer Risk Assessment at the Time of Screening Mammography: Perceptions and Clinical Management Outcomes for Women at High Risk

The purpose of this study was to evaluate the utility of a breast cancer risk assessment (BCRA) at the time of screening mammogram. Women whose BCRA indicated a high risk for cancer received a letter with instructions for breast health care and genetic counseling if appropriate. After 6 months this group received surveys to evaluate their risk perception and their recall of, and compliance with, recommendations. We also explored the impact of other variables such as a recommendation for genetic counseling and physician communication with the women. After the BCRA, the majority of high risk women reported no change in their perceived risk of cancer. A woman’s perceived risk of cancer after a BCRA was significantly associated with her recall of recommendations for breast health care, but not with compliance. A recommendation for genetic counseling was not significantly related to women’s perceived risk of cancer after the BCRA. Ten percent of women who should have obtained genetic counseling actually completed an appointment. Women who discussed their BCRA results with their physicians were more compliant with a six month breast exam with a doctor (53% vs 17%, p = 0.018). Overall, women felt that the BCRA was helpful and did not cause undue stress or anxiety. Although the cohort’s compliance with recommendations was suboptimal, physicians’ interactions with their patients may have a positive influence on their compliance.     

Semantic priming by irrelevant speech

To-be-ignored, task-irrelevant speech disrupts serial recall performance relative to a quiet control condition. In most studies, the content of the auditory distractors had no effect on their disruptive potential, one’s own name being one of the few exceptions. There are two possible explanations of this pattern: (1) Semantic features of the irrelevant speech are usually not processed, except for highly relevant auditory distractors, or (2) semantic processing of the irrelevant speech always occurs, but usually does not affect serial recall performance. To test these explanations, we presented to-be-ignored auditory distractor words drawn from different categories while participants memorized visual targets for serial recall. Afterwards, participants were invited to what they believed to be an unrelated norming study, in which they were required to spontaneously produce words from the categories from which the auditory distractor words were drawn. Previously ignored words were produced with a higher probability than words from a parallel, nonpresented set, demonstrating that features of to-be-ignored, task-irrelevant speech that do not interfere with immediate serial recall performance are nevertheless processed semantically and may have substantial effects on subsequent behavior.     

Asymmetrical cortical processing of radial expansion / contraction in infants and adults

We report asymmetrical cortical responses (steady‐state visual evoked potentials) to radial expansion and contraction in human infants and adults. Forty‐four infants (22 3‐month‐olds and 22 4‐month‐olds) and nine adults viewed dynamic dot patterns which cyclically (2.1 Hz) alternate between radial expansion (or contraction) and random directional motion. The first harmonic (F1) response in the steady‐state VEP response must arise from mechanisms sensitive to the global radial motion structure. We compared F1 amplitudes between expansion‐random and contraction‐random motion alternations. F1 amplitudes for contraction were significantly larger than those for expansion for the older infants and adults but not for the younger infants. These results suggest that the human cortical motion mechanisms have asymmetrical sensitivity for radial expansion vs. contraction, which develops at around 4 months of age. The relation between development of sensitivity to radial motion and cortical motion mechanisms is discussed.     

The Protective Role of the Family and Social Support Network in a Sample of HIV-Positive African American Women: Results of a Pilot Study

This study examined the role of family functioning and social support in protecting HIV-positive African American women from the adverse psychological consequences associated with deterioration in their CD4 cell count. Participants were 38 African American HIV-positive women who had recently given birth. Results demonstrated that changes in CD4 cell counts were inversely predictive of psychological distress and were moderated by family functioning and social support satisfaction. Women with good family functioning were less affected by changes in their CD4 cell counts, and women with poor family functioning were more emotionally responsive to changes in CD4 cell count. Unexpectedly, women from families where conflicts tended to be clearly laid out and discussed were also more responsive to both changes in CD4 cell counts. Interventions are recommended that increase a client's social support satisfaction, foster an adaptive level of connectedness to family, and enhance the family's range of conflict resolution styles.
