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. 相似文献

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. 相似文献

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. 相似文献

Experimental evidence is presented which explores the social stimulus value of pregnancy. It was found that, for men especially, the pregnant woman elicits avoidance and staring and that these responses occur primarily because pregnancy is a novel visual stimulus. For women, avoidance seems to be tied less to the stimulus aspects of the pregnant woman than to role expectations about her behavior. The pregnant woman is expected to be passive, but is simultaneously rejected for being so. It is argued that this constellation of responses may produce discomfort and withdrawal in the pregnant woman herself, since avoidance and staring are easily interpreted as negative reactions. How these reactions fit into the cultural response to pregnancy is discussed. 相似文献

In the present study, the effect of food-related cues on the desire to eat chocolate in hungry and satiated subjects was investigated.
Subjects (n=46) were randomly assigned to either a hungry or satiated group and then assigned to a group receiving one of the following
stimuli: taste (2 M&Ms), sight (a photograph of M&Ms), cognition (a passage describin M&Ms), or control (no stimulus). In
each testing session, subjects rated their desire to eat chocolate before and after the 90-s presentation of the particular
stimulus. Each subject was then given a half pound of M&Ms so that actual consumption could also be measured. Results indicated
that, following the presentation of the sight and taste stimuli, the subjects’ desire to eat chocolate was significantly increased.
Furthermore, no differences in chocolate consumption due to state of hunger or type of food-related stimulus presented were
found. 相似文献

Research indicates that in general, curiosity leads to more intense processing of an advertisement, which might result in a more skeptical response toward a persuasive message. However, we propose the opposite and argue that a process of evoking curiosity toward a stimulus in the first step (with the creation of an information gap) and resolving it in the second step creates a positive affective experience. Upon receiving curiosity-resolving information after becoming curious, consumers are less skeptical toward the advertised product, which leads to a more favorable attitude and a higher purchase intention. Based on four studies, we demonstrate curiosity's skepticism-reducing effect, its downstream consequences, and the underlying mechanism of positive affect. We show that this curiosity-stimulating way of information disclosure caused the effect instead of the information itself, which remained constant. The effects occur for integral curiosity, directed at the focal product, and for incidental curiosity, elicited by an unrelated stimulus. These results contribute to understanding consumer responses to curiosity-evoking advertisements, which are widespread, and provide implications for consumer psychologists, practitioners, and policy makers. 相似文献

This study examined the influence of gender and various background factors on science anxiety. Students (50 women, 37 men) took the Science Anxiety Scale (Mallow, 1994), provided information about high school and college academic accomplishments, described gender-role stereotyping in the home, and evaluated their science teachers and science experiences. Most participants were Caucasian and from an upper-middle class background. Women were not uniformly more science anxious and had a relatively similar science background to men, although they had higher science grades in high school and did report less stringent sex-role socialization in the home. However, students with high science anxiety took fewer science courses in college, had lower SAT-Q scores, and reported that their high school science teachers were not helpful. The findings regarding gender- and anxiety-linked differences are discussed in terms of women's and men's differential interpretations of their abilities, the influence of parental gender typing on pursuit of science, and the gender-appropriateness of studying science. 相似文献
