Interactions between area and numerosity

Summary The concept of filled area, i.e. the impressionistic ensemble of parts of a stimulus field occupied by dots, is used to account for various kinds of numerosity illusions due to perceptual interaction between a number of dots and their spatial arrangement. A measure of filled area is derived from a model for the perceptual clustering of dots on the basis of relative proximity. It is shown that the quantified concept of filled area successfully predicts illusion data from earlier studies. Subsequently, a two-alternatives forced-choice numerosity experiment is reported, the data of which gave further evidence of the predictive power of the filled-area hypothesis. Our approach is discussed with respect to spatial features of dot stimuli that might be in rivalry with the filled-area factor in numerosity-estimation tasks.     

Home,school, and playroom: Training grounds for adult gender roles

Gender differences in children's play activities, preferred school subjects, and occupational goals were examined in relation to such parental variables as toy-giving and chore assignment. Subjects were 245 children in grades K, 3, 6, and 8. Subjects completed questionnaires before and after Christmas asking what gifts they wanted, asked for, received, and liked best. They also were asked to name their friends and play activities, favorite and least-liked school subjects, occupational aspirations, and chores at home. Children generally wanted, asked for, received, and most-liked gender-typical toys. They were less likely to receive requested gender-atypical toys. Children's preferred activities, job aspirations and assigned chores were along gender-typical lines. Girls preferred masculine toys and jobs more than boys preferred feminine ones. With increasing age, both girls and boys increasingly preferred masculine toys and male friends. No gender differences in favorite or least-liked school subjects were found. School subject preference was related to gender-typing of occupational choice for girls but not boys.An earlier version of this paper was presented at the annual meeting of the American Psychological Association, Anaheim, California, 1983.     

Perceptions of women: Effects of employment status and marital status

Eighty-four female and 84 male college students evaluated a briefly described female stimulus person on 20 seven-point bipolar scales which described personality traits and professional competencies. Each subject rated 1 of 12 women who were described as either never married, divorced, widowed, or married and as either employed full-time, employed part-time, or unemployed. As hypothesized, the personal traits and professional competencies of employed women were evaluated more favorably than those of unemployed women, and the personality traits of married women were perceived more positively than those of unmarried women. Contrary to predictions, unmarried and married women were perceived as equally competent.Portions of this paper were presented at the meeting of the American Psychological Association, Washington, D.C., August 1982.     

Multifactor measurement of bodily feelings: Conceptual development,scale construction,and empirical validation

A series of studies is described demonstrating a coherent exploratory and confirmatory factor-analytic approach to the scaling of self-reported bodily feelings. This approach attempts to optimize the orthogonality, parsimony, and meaningfulness of a multifactor inventory. Psychometric properties of the resulting 35-item Bodily Feeling Scale (BFS) are presented and its comparability with other inventories is discussed. A validity study using item-content-based scales of the Minnesota Multiphasic Personality Inventory showed both concurrent and discriminative validity of the BFS. Implications for clinical and research utility are discussed.Portions of this research were conducted while the first author was supported by a University Graduate Fellowship awarded by the Graduate School of Arts and Sciences at Vanderbilt University.Professor Nunnally passed away in August 1982. His major contributions to the several stages of this research program are recognized through coauthorship.     

New wave or second stage? Attitudes of college women toward feminism

The attitudes of female subjects toward gender roles, gender inequality, and the women's movement were measured using a 24-item attitudinal inventory. Subjects tended to hold nontraditional but only moderately feminist attitudes toward gender roles. They were, however, highly aware of gender inequality and supportive of the women's movement, although they were also reluctant to identify themselves as feminists. T tests revealed that subjects most supportive of feminism were advanced students (juniors and seniors) and students who had personally experienced discrimination. But when personal experience of sex discrimination was controlled for, the strength of the relationships between class level and gender role attitudes, and between class level and support for the women's movement, diminished. Students who had personally experienced sex discrimination are less traditional and more feminist in their gender role attitudes, and show stronger support for the women's movement, regardless of their class level, than students who have not had such experiences. These findings are interpreted and their implications for the future of the women's movement are discussed.     

TRAINING AND GENERALIZATION OF REACH-GRASP BEHAVIOR IN BLIND,RETARDED YOUNG CHILDREN

The effects of a graduated prompting treatment procedure were analyzed in three phases of an experiment on the training and generalization of reaching-grasp responding in 2- to 4-year-old blind, severely or profoundly retarded children. In Phase 1, we used a multiple-baseline across-subjects design to investigate the effectiveness of the treatment on midline reach-grasp responding. In Phase 2, we used a reversal design to investigate the effects of repeated implementations and withdrawals of the treatment. In both phases, generalization to right and left positions was measured. In Phase 3, in a multiple-baseline across-responses design, the treatment was implemented in right and left positions. Also in Phase 3, shift of stimulus control from toy-sound to verbal instructions was measured. The results showed that (a) the graduated prompting procedure was effective in training reach-grasp responding in all three children; (b) for one child, the effects were durable over repeated applications of the treatment procedure, but were not maintained during withdrawals; (c) for another child, the treatment procedure was effective in teaching reach-grasp responding in all three positions; and (d) for the same child, training of reach-grasp responding generalized to toys presented without sound, given only the verbal instruction.     

Development of sex biases in children: 40 years later

Children in grades 2–10 (200 of each sex) assigned desirable and undesirable traits to girls or boys. Half the subjects had an additional option of both sexes. Children in all grades assigned more desirable traits to their own sex and more undesirable traits to the opposite sex, in line with Smith (1939). Both sexes became less positive toward their own sex and more positive toward the opposite sex with increasing age. This pattern also had characterized girls in Smith's study, whereas, boys had shown the opposite pattern. Beginning in the sixth grade, girls were more apt than boys to assign desirable traits to their own sex. Availability of the “both sexes” option decreased stereotyping, especially in girls.     

Sexism and beautyism in women's evaluations of peer performance

The purpose of this study was to investigate independent and interactive effects of physical attractiveness (PA), sex, and task sex-typing on performance evaluations. Subjects were 216 college women who read poorquality essays written on masculine, feminine, or neutral topics. Essays supposedly were written by a male or a female student who was either attractive, unattractive, or physically unidentified. Results indicated that PA enhanced evaluations of both male and female essayists, except for the predicted effect that female attractiveness is less beneficial for masculine than feminine task performances. Women did not evaluate the sexes differently, and sexism was largely restricted to the interactive effects of PA. PA stereotypes also affected causal attributions of performers' outcomes in a manner consistent with attribution theory. These data are considered in the context of the existing literature and the directions for further research on sexism and beautyism.
