Reproductive freedom, self-regulation, and the government of impairment in utero

This article critically examines the constitution of impairment in prenatal testing and screening practices and various discourses that surround these technologies. While technologies to test and screen (for impairment) prenatally are claimed to enhance women's capacity to be self-determining, make informed reproductive choices, and, in effect, wrest control of their bodies from a patriarchal medical establishment, I contend that this emerging relation between pregnant women and reproductive technologies is a new strategy of a form of power that began to emerge in the late eighteenth century. Indeed, my argument is that the constitution of prenatal impairment, by and through these practices and procedures, is a widening form of modern government that increasingly limits the field of possible conduct in response to pregnancy. Hence, the government of impairment in utero is inextricably intertwined with the government of the maternal body.     

Cross-sectional and longitudinal relations among peer-reported trustworthiness, social relationships, and psychological adjustment in children and early adolescents from the United Kingdom and Canada

Trustworthiness was examined in children and early adolescents from two countries. In Study 1,505 children in the fifth and sixth school years in the United Kingdom (mean age = 9 years 7 months) were tested across an 8-month period. In Study 2,350 sixth- through eighth-grade Canadian children and early adolescents (mean age = 12 years 11 months) were tested across a 1-year period. Participants completed measures assessing trustworthiness (ratings of promise and secret keeping by peer group and also by best friend in Study 1), assertiveness (Study 1), prosocial behavior (Study 2), social relationships (friendships and peer preference), and psychological adjustment (self-esteem, depressive symptoms, and loneliness). Peer-reported trustworthiness was positively associated with, and predicted changes across time in, the number of friendships. The observed relations were found to be statistically independent of peer preference and peer-reported assertiveness or prosocial behavior. Trustworthiness was found to be positively associated with peer preference (Study 1 and Study 2) and psychological adjustment (Study 1).     

A Review of Spiritual and Religious Measures in Nursing Research Journals: 1995--1999

Background: A series of systematic reviews has revealed relatively high levels of interest in religion and spirituality in different nursing specialties, but not in general nursing research journals. Purpose: To identify the extent to which spirituality and religiousness were measured in all quantitative and qualitative research articles published in Research in Nursing and Health, Nursing Research, Advances in Nursing Science (ANS), and Image: The Journal of Nursing Scholarship from 1995 to 1999. Methods: A full-text search was conducted of ANS and Image using the Ovid search system. Nursing Research and Research in Nursing and Health were hand searched for spiritual/religious measures. Characteristics of selected studies, the measures taken, and their uses were coded for data analysis. Results: A total of 564 research studies were identified, of which 67 (11.9%) included at least one measure of spirituality or religiousness. A significant difference was found between the percentage of qualitative and quantitative studies that contained measures of these concepts. Of the 119 qualitative studies, 23 (19.3%) contained a measure of religion or spirituality, compared to 44 of the 445 (9.9%) quantitative studies. Nominal indicators of religious affiliation were the most commonly used measures in the quantitative studies and measures of religion and spirituality were rarely used in the analyses. Although only a few quantitative or qualitative studies intended to focus on religion or spirituality, these themes often emerged spontaneously in the qualitative research. Conclusions: Research in Nursing and Health, Advances in Nursing Science, Nursing Research, and Image: The Journal of Nursing Scholarship all published research measuring spirituality and religiousness during the time-period studied. The rate at which spirituality and religion appeared in these nursing research articles is substantially higher than that found in most fields outside of nursing. Even more frequent inclusion of spiritual and religious variables and richer measures of spirituality and religiousness would help to increase the available scientific information on the role of spirituality and religion in nursing care.     

Publication rates of male and female academic clinical psychologists in California

Compared here was the publication rate of men and women surveyed by mail (480 academic clinical psychologists in California) regarding number of publications, self-perception of their role of researcher versus teacher, variables related to research opportunity (grants, time spent in research), and type of institution in which they are employed. The men had 1.6 as many publications per year as did the women, and the semipartial correlation was -.21 for sex in the last step of a multiple regression and accounted for an additional 4% of the variance. Thus, the men published more, even when ostensible opportunities were controlled. For this sample variables of sex and self-perception of role of researcher versus teacher were more highly correlated with number of publications than were the research opportunity variables of grants, time spent in research, and type of academic institution of employment.     

Stereoscopic surface interpolation supports lightness constancy

The human visual system has a remarkable ability to construct surface representations from sparse stereoscopic, as well as texture and motion, information. In impoverished displays where few points are used to define regions in depth, the brain often interpolates depth estimates across intervening blank regions to create a compelling sense of a solid surface. The set of experiments described here examined stereoscopic interpolation using a novel technique based on lightness constancy. The effectiveness of this method is notable because it stands as the only technique to date that unequivocally examines the perception of interpolated surfaces, and not surfaces inferred subjectively from depth information in the stimulus. Further, these data support the growing evidence that a primary function of the stereoscopic system is to define three-dimensional surface structure.     

Object individuation: infants' use of shape, size, pattern, and color.

Recent research indicates that when an event-monitoring paradigm is used, infants as young as 4.5 months of age demonstrate the ability to use featural information to individuate objects involved in occlusion events (Wilcox & Baillargeon, 1998a, Object individuation in infancy: The use of featural information in reasoning about occlusion events. Cognitive Psychology 37, 97-155; Wilcox & Baillargeon, 1998b, Object individuation in young infants: Further evidence with an event monitoring task. Developmental Science 1, 127-142). For example, in one experiment (Wilcox & Baillargeon, 1998b, Object individuation in young infants: Further evidence with an event monitoring task. Developmental Science 1, 127-142) 4.5-month-old infants saw a test event in which a green ball with colored dots disappeared behind one edge of a narrow or wide screen, and a red box with silver thumbtacks appeared at the other edge; the narrow screen was too narrow to hide both objects simultaneously, whereas the wide screen was sufficiently wide to hide both objects at the same time. The infants looked reliably longer at the narrow- than at the wide-screen test event. These and control results suggested that the infants had: (a) used the featural differences between the ball and box to conclude that two objects were involved in the event; (b) judged that both objects could fit simultaneously behind the wide but not the narrow screen; and hence (c) were surprised by the narrow-screen event. The present experiments build on these initial findings by investigating the features to which infants are most sensitive. Four experiments were conducted with infants 4.5-11.5 months of age using the same procedure, except that only one feature was manipulated at a time: shape, size, pattern, or color. The results indicated that 4.5-month-olds use both shape and size features to individuate objects involved in occlusion events. However, it is not until 7.5 months that infants use pattern, and 11.5 months that infants use color, to reason about object identity. It is suggested that these results reflect biases in the kind of information that infants attend to when reasoning about occlusion events. Possible sources of bias are discussed.     

A Twin and Family Study of the Association Between Immune System Dysfunction and Dyslexia Using Blood Serum Immunoassay and Survey Data

We conducted a study of the association between developmental reading disability (DRD) and immune disorders (ID) using both survey and immunoassay data in two separate samples of families. One sample was made up of twins and their parents and was ascertained through a population-based sampling scheme. The other sample was a set of extended pedigrees selected for apparent autosomal dominant transmission of DRD. We failed to find an association between DRD and ID in either sample, regardless of the method used to assess immune system function. Even though our twin sample provided evidence that both DRD and immune conditions were significantly heritable, there was no evidence for a genetic correlation between ID and DRD nor was there any clear indication that a special subgroup of individuals may be comorbid for these conditions because of genetic reasons. How these negative findings can be reconciled with the developmental hypothesis of Geschwind, Behan, Galaburda, and colleagues, and how they may relate to the gene locus influencing DRD that has been recently located in the HLA region of the short arm of chromosome 6 is discussed.     

Object individuation in young infants: Further evidence with an event-monitoring paradigm

Recent results indicate that, when tested with an event-monitoring task, 7.5- and 9.5-month-olds give evidence that they can individuate objects in different-objects occlusion events – events in which two distinct objects appear successively on either side of an occluder (Wilcox and Baillargeon, in press). The present research sought to confirm and extend these findings. The experiments examined 7.5- and 4.5-month-olds’ ability to correctly interpret a different-objects (ball-box condition) and a same-object (ball-ball condition) occlusion event. The infants in the ball-box condition saw a test event in which a ball disappeared behind the left edge of a screen; after a pause, a box emerged from behind the screen's right edge. For half of the infants (wide-screen event), the screen was wide and could occlude the ball and box simultaneously; for the other infants (narrow-screen event), the screen was narrow and should not have been able to occlude the ball and box at the same time. The infants in the ball-ball condition saw identical wide- and narrow-screen events except that the ball appeared on both sides of the screen. The infants in the ball-box condition looked reliably longer at the narrow- than at the wide-screen event, whereas those in the ball-ball condition tended to look equally at the events. These results suggest that the ball-box infants (a) were led by the featural differences between the ball and box to view them as distinct objects; (b) judged that the ball and box could both be occluded by the wide but not the narrow screen; and (c) were surprised in the narrow-screen event when this judgment was violated. In contrast, the ball-ball infants (a) assumed, based on the featural similarities of the balls that appeared on either side of the screen, that they were one and the same ball, and (b) realized that the ball could be occluded by either the wide or the narrow screen. These results indicate that, by 4.5 months of age, infants are able to use featural information to correctly interpret different-objects and same-object occlusion events. These findings are discussed in the context of the newly-drawn distinction between event-monitoring and event-mapping paradigms (Wilcox and Baillargeon, in press).     

Sex, sex-role identification, and awareness of sex-role stereotypes

An experiment was run to determine if androgynous people have transcended traditional sex roles or merely incorporated both sex roles into their repertoire. Masculine sex-typed, feminine sex-typed, and androgynous people listed as many masculine and feminine stereotypes as they could think of in a time-limited task. Highly sex-typed individuals showed more awareness of their own sex's attributes than the other sex's stereotypes. Androgynous people showed greater awareness of both sexes' attributes as compared with sex-typed people, indicating support for the incorporation hypothesis rather than the transcendance hypothesis. However, the stereotypes androgynous people listed were somewhat less evaluative in tone compared with those of sex-typed people, Overall, subjects listed more stereotypes of females than males, and female stereotypes were more negative than male stereotypes.     

Perceptions of the magnitude and diversity of social support

Three studies were conducted to test the hypotheses that subjects would overestimate the proportion of their peers who shared their opinion on an issue and that they would perceive their own opinion group as consisting of people with a wider and more diverse range of values and outlooks than those holding different opinions. The first study was conducted following a period of intense debate about sixism on a college campus. Subjects estimated student opinion on issues related to sexism and indicated how diverse or similar they perceived supporters and nonsupporters of the women's movement to be. In a second study subjects estimated the proportion of students who evaluated President Carter's performance as good, fair, or poor and then indicated how diverse or similar the three groups of students were who held these various opinions. A third study closely replicated the second, using the issue of divestiture of college-owned stock in South Africa. In all three studies, subjects were divided into groups on the basis of their own attitudes. Results consistently supported the hypotheses.
