Are sisters of twin brothers behaviorally or physiologically masculinized? Prenatal exposure to their brothers' androgens and postnatal socialization experiences unique to girls growing up with twin brothers might influence their attitudes, pubertal development, and reproductive histories. To investigate, we studied age- and cohort-matched samples of Finnish sisters from same-sex and opposite-sex twin pairs. Using data from two ongoing longitudinal studies of consecutive birth cohorts of Finnish twins, we assessed pubertal development at ages 11 and 14 and endorsement of attitudes associated with femininity at age 16. We also studied fertility in Finnish women from same- and opposite-sex twin pairs born from 1958 through 1971, obtaining information on their child-bearing histories when they were ages 15 to 28. Results of each comparison were unambiguously negative: There was no evidence of differences between sisters from same- and opposite-sex twin pairs, and thus, no evidence of either androgenization or cross-sex socialization.  相似文献

OBJECTIVE: This study is aimed at enhancing understanding prenatal screening decision making through testing a hypothesized decision model based on decision theory and health behavior theory. DESIGN: We obtained questionnaires from 1,666 pregnant women who were offered prenatal screening for Down's syndrome. Path analysis (using LISREL) resulted in a final model with reasonable model fit, which was verified by split-sample cross-validation. MAIN OUTCOME MEASURES: These included perceived probability, perceived severity, attitude toward termination, response efficacy, attitude toward prenatal screening, subjective norm, child-related anxiety, and intention to undergo prenatal screening. RESULTS: Attitude toward termination of pregnancy, perceived test efficacy, and subjective norm regarding the desirability of having prenatal screening determined a woman's attitude toward having a prenatal test. Anxiety was influenced by perceived risk and perceived severity of having a child with Down's syndrome, and by subjective norm, but this appeared to be a weak predictor of intention to test. Pregnant women with a positive attitude toward prenatal screening, and who perceived a subjective norm in favor of undergoing prenatal screening, showed a greater intention to have prenatal screening done. CONCLUSION: These findings suggest that more attention should be paid toward the values and social context of pregnant women during the counseling process.  相似文献

While several studies suggest that individuals with autism use prior knowledge appropriately, others have found that this may be a particular area of weakness. The aim of the current study was to investigate whether individuals with autism and Asperger’s syndrome utilize prior knowledge when pairing objects with colours. Participants were presented with cards illustrating common objects and asked to pair them with one of two colour patches. Some target objects were coloured inappropriately (e.g. blue banana), allowing a participant to pair it either with blue or yellow. Results indicated that a majority of participants chose the associated in preference to the surface colour. This suggests that prior knowledge governed pairing in many individuals with autism and Asperger’s syndrome as it did in comparison groups, except in typically developing children aged 5 years. However, those with autism and moderate learning difficulties were less affected by prior knowledge than some of the other groups.  相似文献

The relation between mood and executive functioning in children and adolescents has not been previously reported. This study examined the association between self-reported depressive symptoms in both clinical outpatient and psychiatric inpatient samples to the following measures of executive functioning: the Controlled Oral Word Association Test, Animal Naming, Trail Making Test, and Wisconsin Card Sorting Test. Records from children and adolescents aged 7–17 years old with an IQ > 70 were examined. Data were gathered at either an outpatient neuropsychology clinic (n = 89) or an inpatient psychiatric hospital setting (n = 81). Mood was measured with the Children’s Depression Inventory. Generally, statistical associations between self-reported depressive symptoms and executive functioning were small and non-significant. The variance predicted by mood on measures of executive functioning was minimal (generally less than 2 %) for the total sample, the outpatient group, inpatient group, and a subgroup who endorsed elevated mood symptoms. These results suggest that impaired performance on measures of executive functioning in children and adolescents is minimally related to self-reported depressive symptoms.  相似文献

Our purpose in this paper is to delineate an ontology for quantum mechanics that results adequate to the formalism of the theory. We will restrict our aim to the search of an ontology that expresses the conceptual content of the recently proposed modal-Hamiltonian interpretation, according to which the domain referred to by non-relativistic quantum mechanics is an ontology of properties. The usual strategy in the literature has been to focus on only one of the interpretive problems of the theory and to design an interpretation to solve it, leaving aside the remaining difficulties. On the contrary, our aim in the present work is to formulate a “global” solution, according to which different problems can be adequately tackled in terms of a single ontology populated of properties, in which systems are bundles of properties. In particular, we will conceive indistinguishability between bundles as a relation derived from indistinguishability between properties, and we will show that states, when operating on combinations of indistinguishable bundles, act as if they were symmetric with no need of a symmetrization postulate.  相似文献

Previous studies from our laboratory have documented that the medial hypothalamic defensive system is critically involved in processing actual and contextual predatory threats, and that the dorsal premammillary nucleus (PMd) represents the hypothalamic site most responsive to predatory threats. Anatomical findings suggest that the PMd is in a position to modulate memory processing through a projecting branch to specific thalamic nuclei, i.e., the nucleus reuniens (RE) and the ventral part of the anteromedial nucleus (AMv). In the present study, we investigated the role of these thalamic targets in both unconditioned (i.e., fear responses to predatory threat) and conditioned (i.e., contextual responses to predator-related cues) defensive behaviors. During cat exposure, all experimental groups exhibited intense defensive responses with the animals spending most of the time in the home cage displaying freezing behavior. However, during exposure to the environment previously associated with a cat, the animals with combined RE + AMv lesions, and to a lesser degree, animals with single AMv unilateral lesions, but not animals with single RE lesions, presented a reduction of contextual conditioned defensive responses. Overall, the present results provide clear evidence suggesting that the PMd’s main thalamic targets (i.e., the nucleus reuniens and the AMv) seem to be critically involved in the emotional memory processing related to predator cues.  相似文献
