The use of assisted reproductive technology is increasing rapidly. Research, although sparse, has resulted in inconsistent findings as to the developmental prognosis for infants conceived by assisted reproductive techniques such as in vitro fertilization and the use of fertility drugs. In the present study, the authors compared twins who were spontaneously conceived with those who were conceived through assisted reproductive technology. The authors found differences in birth weight and gestational age. Infants conceived by assisted reproductive technology fared worse than did those who were spontaneously conceived. The authors found no differences between the groups in mental development at 24 months of age, but they found evidence of differences in physical development. Implications of the findings are discussed.  相似文献

Assisted reproductive technologies (ART) lack biological filters that are part of the natural fertilization process and thus might enable the presence of abnormal genetic materials. Whereas the findings regarding neonatal and neurological risks among ART-conceived children are rather consistent, data regarding cognitive and social-emotional developmental outcomes are inconsistent. The aim of this study was to examine the association between ART and cognitive and social-communication outcomes among pre-school children. The results indicated that the cognitive and social-communicative abilities of the ART-conceived children were similar to those of the spontaneously conceived children; however, according to parental reports, children in the ART group had higher communicative skills and better motor abilities than spontaneously conceived children. These results should be interpreted with caution as we used measures that assess global cognitive abilities that may not be sensitive to more subtle differences of higher cognitive and social-communication abilities in infancy that may become more prominent later in life. Although infertile couples and professionals in the field of ART can be reassures by the current findings, further research is needed as well as follow-up evaluation of this population during school age.  相似文献

In this study we examined the congruence between partners’ perceptions of their marital relationship during the transition to parenthood and the effect of depression during pregnancy on couples’ congruence during the early postpartum period. Thirty-one couples who conceived spontaneously, along with thirty-five who conceived through assisted reproductive technologies (ART), provided data on their marital relationship and depression at their 24th pregnancy week and four months after the partum. All couples reported a decrease in marital congruence. Couples who conceived through ART reported lower marital congruence. For these subjects, women’s depression was associated with lower congruence. Interventions that focus on strengthening the marital relationship across the transition to parenthood should assess and promote couples’ congruence.  相似文献

This two-cohort longitudinal study on the development of the semantic grouping strategy had three goals. First, the authors examined if 6–7-year-olds are nonstrategic before becoming strategic after prompting at 8–9 years of age, and if 8–9-year-olds are prompted strategic before spontaneous strategy use at 10–11 years of age. Children 6–7 and 8–9 years old performed two sort-recall tasks (one without and one with a grouping prompt) at two time points separated 1.5 years from each other. Second, the authors investigated whether short-term or working memory capacity at time point 1 predicted recall in children who did or did not use the semantic grouping strategy 1.5 years later. Third, the authors investigated whether prompted strategic children and children who used the strategy spontaneously differed in strategy transfer to a new task. Developmental results confirmed previous cross-sectional results, but in a longitudinal two-cohort study 6–7-year-olds were nonstrategic, and became prompted strategic around 8–9 years of age, followed by spontaneous strategy use at age 10–11 years. The authors found that memory capacity was not predictive of later use of the strategy. New findings were that prompted strategic children were as equally able as spontaneously strategic children to transfer the strategy to a new task, albeit with smaller recall benefits.  相似文献

Conception after assisted reproductive methods is associated with considerable emotional as well as physical stress. Parents often have to wait ten years or more before conceiving. As part of an ongoing U.K. study, we assessed 140 intracytoplasmic sperm injection (ICSI) conceived children and 101 naturally conceived control children via parental completion of the Eyberg Child Behaviour Inventory when their children were two years old. Parents of children conceived after assisted reproductive methods reported fewer behavioral problems. Implications for long‐term development are discussed. ©2004 Michigan Association for Infant Mental Health.  相似文献

The purpose of this research was to explore when people recognize prejudice in those who make bigoted remarks, and whether such expressions of bigotry backfire to harm those who express them. The results of Study 1 suggest that people attribute prejudice to speakers who make stereotypical generalizations about either ascribed (e.g., race, age, sexual orientation) or assumed (e.g., occupational) groups, but have more difficulty recognizing prejudice in those who express positive stereotypes. Study 2 found that bigoted speakers were perceived as less likeable, even by in-group members who agreed with their remarks. Study 3 replicated these findings in a more realistic paradigm, and found that those who made prejudiced remarks were spontaneously described as bigoted. Such negative reactions were again obtained even from like-minded in-group members, with follow-up analyses suggesting that these reactions primarily characterized a subset who spontaneously noted the bigotry and that these reactions mediated negative impressions.  相似文献

The relationships between socioeconomic and biogenetic reproduction are always socially constructed but not always acknowledged. These relationships are examined as they apply to an instance of infertility and assisted reproduction presented in a seventeenth-century English play, Thomas Middleton's 1613 comedy, A Chaste Maid in Cheapside. Middleton's satirization of the effects of secrecy on the category of reproductive disability is analyzed and its applicability to our own time considered. The discussion is in four parts, focusing on: the attribution of disabled status to one member of the couple, the wife; the use of this attribution to protect the husband's reputation for sexual and reproductive health; the concealment of the nature of assisted reproduction; and the interests of the child conceived with such assistance.  相似文献

Abstract

Chronic pelvic pain (CPP) in women of reproductive age is a common complaint; for many women no identifiable pathology can be found. Research has suggested that women who have chronic pelvic pain without obvious pathology differ on a range of psychological characteristics, such as anxiety and depression, compared with those with identified pathology. A meta-analysis of 22 studies was undertaken to clarify these issues. Results showed that there were no significant differences on a range of psychological variables between women who were identified, via laparoscopy and clinical judgement, as having organic disorders and those who were not so identified. When women with chronic pelvic pain were compared with pain-free groups a profile of elevated depression, anxiety, neuroticism and psychopathology was found which is consistent with findings from studies of other painful conditions.  相似文献

The authors investigated the link between children's temperament and the development of asthma and allergies. Prospective longitudinal data on children at the ages of 3-5 months, 3-5 years, and 7-9 years were collected. At age 7-9 years, analyses were performed on data for 3 groups of children (n = 42): those with asthma (no allergies), those with allergies (no asthma), and those with neither asthma nor allergies (the control group). Data for children who developed asthma or allergies prior to age 7-9 years were not analyzed. Differences were found in the premorbid period between the control group and the children who later developed asthma or allergies as well as between the asthma and allergy groups. After onset of illness, no temperamental differences were observed between the 3 groups. The study shows the importance of longitudinal design for asthma research.  相似文献

A sample of nearly 500 urban married women with children was used to evaluate the possible effect of outside-the-home employment on the mental and physical health of married mothers. Six measures of health were used, some drawn from interviews with the women, others from a medical examination. After controlling for ethnicity, education, and age of the women, the husband's occupation, number of children in the family, and length of time the woman has been married, it was found that wives who had been employed for more than a year were healthier than wives not employed outside the home and wives who had worked less than one year. Housewives who had never worked outside the home were healthier, on the whole, than wives who had been employed at some time in the past. Poor marital relationships and having no preschool age children seemed to increase the health advantage of long-term employed wives over those in the housewife categories. The occupational status of wife and husband did not seem to change these health differences very much.An earlier version of this paper was presented at the annual meeting of the Southwest Social Science Association, San Antonio, March 1975. The authors would like to thank Donna Duvall, Ministry of State for Urban Affairs, Ottawa; Elaine Hess, University of Nebraska at Omaha; and David R. Johnson, University of Nebraska — Lincoln for their comments. Gilles Robert and Marie Josepha Hebert ably assisted with various aspects of this project. Support for the project was provided by the Ministry of State for Urban Affairs, but the views expressed here are those of the authors and not necessarily those of the Ministry.  相似文献

In this study, the authors examined age differences in social network characteristics (SNC) among Hong Kong Chinese. The sample consisted of 596 Chinese adults, ranging from 18 to 91 years old. Age was positively associated with close social partners and negatively associated with peripheral social partners. For individuals who were more likely to define the self as interconnected with others (i.e., interdependent self-construal), increasing age was associated with a greater number of close social partners. The negative association between age and the number of peripheral social partners, well-documented in the Western literature, was found only among Chinese adults with lower interdependence but not among those with higher interdependence. These findings highlight the importance of examining the underlying mechanism rather than a particular pattern of SNC across cultures.  相似文献

After reviewing some of the relevant literature, the writers proceed to describe a new development in psychotherapy for couples presenting with relatively unexplained infertility. Several couples who had failed to achieve conception (despite the use of assisted reproductive techniques and personal psychotherapy) were brought together into a supportive-expressive group led by the writers, an experienced analytic cotherapy couple. An interesting outcome is described, and mention made of current plans for a future research project.  相似文献

ABSTRACT

This article focuses on the field of assisted reproductive technology (ART) and psychoanalysis as it relates to people who’ve struggled emotionally in pursuit of their wish to create a family. Recent medical advances have changed baby-making to the extent that infertility is no longer a terminal diagnosis (Ehrensaft, 2012). New opportunities exist to create a family through introduction of a third party in the process of conception via in vitro fertilization, the use of donor egg and/or sperm, intracytoplasmic sperm injection, and surrogacy. The realities raised by these new methods have challenged usual cultural ideas of what constitutes a family, as well as what it means to become a parent or give birth to a child (Ehrensaft, 2000; Notman, 2011; Samish, 2006). The subject of reproductive medicine has stimulated a wide range of emotions within the community of people who suffer infertility and among psychotherapists who become involved with them in analytic and psychotherapeutic relationships.  相似文献

The purpose of the present investigation was to examine the immediate and sustaining effects of monetary and social rewards on specific exploratory behavior. Specific exploratory behavior was conceived as a behavioral expression of intrinsic motivation and was measured by the number of additional requests for viewing blurred tachistoscopically presented slides of varying degrees of uncertainty. The results of the study showed that when monetary and social rewards were presented contingent on performance, exploration increased at the upper levels of uncertainty above a control group. It was also found that after removal, females who had previously received social rewards sustained a significantly higher level of exploration above the control group, while males who had previously received social rewards, as well as both males and females who had previously received monetary rewards, did not differ significantly from the control. The discrepany between these findings and previous findings is explained in terms of theoretical differences in defining and measuring intrinsic motivation.  相似文献

Sex differences in attribution of causality are investigated in three types of television programs: prime-time family, violent, and daytime serial shows. Both frequency and type of causal statements were studied, using DeCharm's conceptualization of personal causation as origin-like (internal to the self) or pawn-like (external to the self). There were striking sex differences in violent programs, with males modeling more origin behavior and females modeling more pawn behavior. In soap operas there were no sex differences, but both origin and pawn ideas were expressed in terms of personal responsibility, with fewer references to more competent origin behaviors such as goal setting, planned decision making, or self-confidence. These findings have implications for differential socialization of competent coping skills for males and females.The authors would like to express appreciation to Katie Henry and Jennifer Mardoyan, who assisted with this research.  相似文献
