Emergent leadership and female sex role identity.

The effects of female sex role identity on self- and rater evaluations of emergent leadership behavior were compared in two studies. We used the same consensus-seeking procedure in both studies to collect the data; only the biological sex composition of the groups in the second study was changed. Study 1 examined 15 mixed-sex groups of 39 female and 21 male students; Study 2 contained 96 female students in 22 same-sex groups. Sex role orientation was measured with the Bem Sex Role Inventory (BSRI: Bem, 1974). Androgynous and feminine-oriented self-ratings of leadership were significantly higher than peer ratings and were also significantly higher than the undifferentiated self-ratings. The self-ratings of masculine-oriented women agreed most closely with peer ratings. Contrary to research and theory, peer evaluation of leadership behavior by sex role orientation did not differ.     

Prime time: fatigue and set effects in the perception of reversible figures.

Subjects viewed unambiguous versions of both stationary and rotating Necker cube illusions for varying durations prior to the presentation of the standard ambiguous figure. In each case, the subjects were more likely to report the ambiguous figure to be (1) in the same configuration as that of the preceding prime following brief preexposure periods and (2) in the opposite configuration from that of the preceding prime following long preexposure periods. In addition, the number of reversals of the figure during the test period was also strongly related to the duration of the preexposure period, with progressively fewer reversals reported following longer preexposure periods. The results are interpreted as revealing the concurrent roles of "set" effects in the brief preexposure conditions and neural fatigue effects in the long preexposure conditions. Furthermore, the ability of the proposed two-process model to integrate the myriad of empirical effects in the reversible-figure literature is emphasized.     

Masculinity, femininity, and women scientists' self-esteem and self-acceptance

The literature suggests women scientists are a unique population. The present study investigated differences in self-esteem, self-acceptance, masculinity and femininity among several sample populations of women, including scientists (n = 62), professionals (other than scientists) (n = 89), college students (n = 83), clients (n = 52), and victims of domestic violence (n = 57). The Personal Orientation Inventory (Shostrom, 1974) and Bem Sex Role Inventory (Bem, 1974) were administered to subjects, together with a demographic data sheet. An ANOVA was used to investigate differences between women scientists and other groups of women, and correlations were used to examine the relationship of masculinity and femininity with self-esteem and self-acceptance. Masculinity was found to correlate with self-esteem for all but the student group and with self-acceptance for all but the student and scientist group. Self-acceptance scores were significantly lower for women scientists than for professional and student groups, and femininity scores were significantly lower for scientists than for all other groups of women.     

Observations on the initiation of eating of new food by weanling kittens

The reaction to a new food and the initiation of its consumption were studied in daily sessions in 19 weanling kittens from four litters at 30–39 days of age. The new food consisted of canned tuna for two litters and cereal (cooked cream of wheat with 3% addition of vegetable oil and broth flavor) for the other two litters. Each litter was divided into two groups. One group was offered the new food in the presence of the mother which had been consuming it (eating cereal had to be induced in the mothers by the hypothalamic stimulation reward method). Another group of kittens received the same food in the absence of the mother. It was found that the kittens which had been offered the new food in the presence of the mother showed only a short-lasting orienting reaction and started to eat the new food on the first or second day (with a mean delay of 0.2 days). On the other hand, the kittens which had been offered the new food in the absence of the mother showed a strong orienting reaction and started to eat the new food only after several daily sessions (with a mean delay of 4.8 days). No significant difference was found between the number of days of delay in eating by kittens offered tuna and by kittens offered cereal in the absence of the mother. The initiation of consumption of the new food by these kittens was preceded by a period of playing with the plate on which the food had been placed. Additional observations showed that the fourto five-month old kittens that had eaten cereal during early training preferred that food over meat pellets; the other kittens of the same age that had eaten tuna, but no cereal, during early training refused to eat cereal when it was offered to them when they were hungry.     

Relationships among spatial skills, communication skills, and field independence in deaf students

The hypotheses that deaf students would be more field-dependent than hearing students and that their competence in communication skills would be positively related to field-independence were supported for a group of 77 male and 67 female deaf students. Step-wise multiple regression analyses of the data showed that for females spatial skills followed by communication skills were significant predictors of field-independence; for males spatial skills followed by the extent of hearing loss were significant predictors of field-independence. Sex differences found on tests of field-independence and spatial relations were consistent with those obtained from the hearing population. It was suggested that socialization experiences and competence in communication skills may influence development of field-independence in deaf students.     

Masculinity,Femininity, and Hispanic Professional Women's Self-Esteem and Self-Acceptance

The literature suggests that whereas women experience unique challenges with self-esteem, Hispanic professional women experience an additional challenge of balancing majority culture values with a more family-oriented ethnic identity. This study investigated differences in self-esteem, self-acceptance, masculinity, femininity, and locus of control among Hispanic professional women, non-Hispanic professionals, scientists, college students, clients, and victims of domestic violence. Masculinity scores were significantly higher for Hispanic professional women, and self-acceptance scores were significantly lower than for other women professionals.
