Individual differences in race schematicity as predictors of African American and white children's race-relevant memories and peer preferences.

Race schematicity, memories for racially stereotyped portrayals, and race-based peer preferences of 70 young children (32 African American, 38 White) were assessed. Consistent with schema-based models of stereotyping, race schematicity was positively and significantly associated with memory distortions of racial stereotype-inconsistent drawings into stereotype-consistent ones. Conversely, race schematicity was negatively and significantly associated with accurate memories for racial stereotype-inconsistent content, and with memory distortions of racial stereotype-consistent portrayals into stereotype-inconsistent ones. As predicted, race schematicity was positively and significantly associated with same-race peer preference bias, as was children's age in months. Results support application of the schematicity construct and relevant social psychological research with adults to the study of young African American and White children's racial stereotyping and processing of race-relevant information.

Effects of gender constancy and figure's height and sex on young children's gender-typed attributions.

Young children's attributions of gender-typed activities to figures/models differing in height and/or sex were examined over three experiments. The influence of gender constancy understanding on children's gender-typed attributions was also examined. In Experiment 1, young children attributed significantly more masculine activities to male than female figures and significantly more feminine activities to female than male figures. Experiment 2 confirmed the results demonstrated in Experiment 1. In Experiment 2, additional line-drawn stimuli and figure comparisons were incorporated; participants attributed significantly more masculine activities to taller than shorter male figures and taller than shorter female figures. In addition, children attributed significantly more feminine activities to taller than shorter female figures. In Experiment 3, participants viewed pictures of taller and shorter male and female models. Results confirmed those of Experiment 1, as well as most of those of Experiment 2. No consistent patterns of children's gender-typed attributions as a function of gender constancy understanding emerged in the three experiments. Results are discussed as they apply to unexplored tenets from Kohlberg's cognitive-developmental model, as well as those of gender schema models, of early gender role development.

Incidence of hydroxychloroquine retinopathy in 1,207 patients in a large multicenter outpatient practice.

OBJECTIVE: To define the true risk of hydroxychloroquine (HCQ) retinal toxicity by studying the largest single group yet evaluated. METHODS: Retrospective chart review of all patients in the Kaiser Permanente Medical Care Program, Southern California Region, who had HCQ prescriptions filled from 1991 through 1993 (1,556 patients in 11 medical centers). Of 1,207 charts of patients who took HCQ and had documented ophthalmologic examinations, initial screening identified 21 charts (1.7%) that indicated possible HCQ toxicity. RESULTS: We identified 1 patient with definite toxicity (1 of 1,207; 0.08%) and 5 other patients with indeterminate but probable toxicity (5 of 1,207; 0.4%). The incidence of definite HCQ retinal toxicity in patients treated with HCQ at <6.5 mg/kg/day was 0. CONCLUSION: In HCQ-treated patients whose renal function is normal, routine ophthalmic screening is not indicated if the daily dosage is <6.5 mg/kg. In patients whose daily dosage is >6.5 mg/kg or who have taken HCQ continuously for > 10 years, annual screening may be appropriate.

Traditional and evaluative aspects of flexibility in gender roles, social conventions, moral rules, and physical laws.

Traditional and evaluative aspects of flexibility regarding transgressions across several domains (masculine and feminine gender roles, moral rules, social etiquette, and physical law) were assessed in 24 4-year-olds, 40 8-year-olds, and 46 college undergraduates. Traditional and evaluative aspects of flexibility yielded distinctly different patterns of response. Data indicated an age-related increase in flexibility on traditional measures (i.e., traditional rule flexibility, cultural relativity) for transgressions in all domains, except physical laws. In contrast, subjects in all age groups were consistently negative in their evaluations of transgressions in moral rules, etiquette, and masculine gender roles. Female subjects viewed masculine gender role transgressions with greater flexibility and less negativity than did male subjects. Results demonstrate the multidimensional character of flexibility development in different social and physical domains. Results suggest that masculine and feminine gender roles and social etiquette may not fall within a common domain of social convention.

Effects of potential partners' physical attractiveness and socioeconomic status on sexuality and partner selection.

Male (n = 170) and female (n = 212) college students viewed photographs, which had been prerated for physical attractiveness, of three opposite-sex individuals. These photographs were paired with three levels of occupational status and income. Subjects indicated their willingness to engage in relationships of varying levels of sexual intimacy and marital potential with the portrayed individuals. Analyses of variance, correlations, and trend analyses supported the hypotheses. Compared to men, women are more likely to prefer or insist that sexual intercourse occur in relationships that involve affection and marital potential, and women place more emphasis than men do on partners' SES in such relationships. Consequently, men's SES and their willingness and ability to invest affection and resources in relationships may often outweigh the effects of their physical attractiveness in women's actual selection of partners. These results and the literature reviewed are more consistent with parental investment theory than with the view that these sex differences are solely the result of differential access to resources and differential socialization.

Transderm scopolamine efficacy related to time of application prior to the onset of motion.

We evaluated Transdermal Scopolamine related to the time of application prior to the onset of motion. In this study 44 subjects participated. The first group applied the transdermal disc within 4 h and the second group 8 h or more prior to the onset of motion. We observed a significant decrease in the incidence and the degree of motion sickness for the group with at least 8 h of scopolamine application prior to sea travel. Therefore, the transdermal scopolamine system should be applied at least 8 h before potentially disturbing motion to provide adequate prophylaxis against motion sickness. We found no significant difference in motion sickness susceptibility between men and women, in contrast to earlier reports.
