This article examines two questions pertaining to the extension of infertility treatment to postmenopausal women. First, what concepts and principles of infertility practice apply to assisted reproduction for the postmenopausal patient? Second, what role should these concepts play in the development of an ethical justification for extending women's reproductive lives past the menopausal boundary? The argument offered here supports their claim to infertility services on the basis of the formal principle of justice, which requires that similar cases be treated similarly. The cases of many postmenopausal patients are argued to be relevantly similar to classes of patients who already receive assistance in reproduction.  相似文献

A mother's (prenatal) wish for a girl has, at times, been implicated as an etiological factor for boyhood femininity or its DSM-III-R diagnostic equivalent, the Gender Identity Disorder of Childhood. In one sample of 52 feminine and 52 nonclinical control boys from Los Angeles, the proportion of mothers who recalled a wish for a girl during the pregnancy did not differ significantly between groups (26.9% vs. 19.2%, respectively); however, in both groups, the maternal wish for a girl was significantly more common in sibships in which all of the proband's older siblings were male. In a second sample of 103 feminine boys from Toronto, the maternal wish for a girl was significantly higher than that found in the Los Angeles sample (43.7% vs. 26.9%), but a control group was not available; as in the Los Angeles sample, the maternal wish for a girl was significantly more common in sibships in which all of the proband's older siblings were male. Implications of these findings for further study of maternal influences on boyhood femininity are discussed.  相似文献

Fee as a variable that could have an impact on college students' perceptions of counseling was explored because of the authentic concerns about college counseling centers needing to charge direct fees for their services. Participants (N = 350) represented a cross-section of potential consumers of psychological services, not just individuals currently receiving services. On an overt level, fees seemed to be less influential in counseling considerations, but were taken into account on a more covert level. This study supports the psychological literature, which suggests that fee is not the most important factor in clients' decisions to seek counseling. Implications for counselors, administrators, researchers, and program planners are discussed.  相似文献

Two experiments addressed the influences of harmonic relations, melody location, and relative frequency height on the perceptual organization of multivoiced music. In Experiment 1, listeners detected pitch changes in multivoiced piano music. Harmonically related pitch changes and those in the middle-frequency range were least noticeable. All pitch changes were noticeable in the high-frequency voice containing the melody (the most important voice), suggesting that melody can dominate harmonic relations. However, the presence of upper partials in the piano timbre used may have accounted for the harmonic effects. Experiment 2 employed pure sine tones, and replicated the effects of Experiment 1. In addition, the influence of the high-frequency melody on the noticeability of harmonically related pitches was lessened by the presence of a second melody. These findings suggest that harmonic, melodic, and relative frequency height relationships among voices interact in the perceptual organization of multivoiced music.  相似文献

Although there are measurable differences in integrative complexity among solutions that individuals generate in dealing with problems, it is uncertain to what extent people comprehend, recognize, and have preferences among different levels of complexity. Integrative complexity is a function of differentiation (the perception of several attributes within, or perspectives about, a topic) and integration (combining the differentiated characteristics in an interactive or synthesizing solution). The current paper reports two experiments dealing with how university students perceive, interpret, and choose among solutions differing in complexity. Experiment 1 showed that subjects accurately rated the complexity of described solutions differing along the continuum, but that their assessment of their own responses differed from the results of expert scoring. Their self-estimated complexity was highly correlated with their preferences, and preferred complexity was reliably higher than either expert- or self-assessed complexity of subject-generated solutions. Subjects were able to hypothesize quite accurately about environmental and endogenous factors likely to affect complexity. Experiment 2 found that in response to problem scenarios, solutions selected as being potentially most effective were consistently more complex than solutions that participants considered themselves most likely to use. The idea of complexity seems to be intuitively recognizable and understandable by untrained subjects: They can and do distinguish among problem solutions (self-generated or presented) that vary on that dimension, and are able to assess accurately the effects of relevant variables. Such subjects also share the bias shown by experts in favour of the superiority of more complex approaches.  相似文献

Mothers of problem and nonproblem toddlers rated videotapes of their own and unfamiliar children's behavior. They classified the behaviors as positive, negative, or neutral, and evaluated the intensity of the positive or negative behaviors. Ratings did not differ by problem status; however, all mothers classified their own children's behavior as less negative than did an independent observer. Mothers also evaluated all children's negative behavior as less aversive than did the observer. Finally, mothers mistakenly classified less of their own children's behavior as negative and more as positive when compared to their biases in classifying unfamiliar children's behavior.  相似文献

Employees high in Trait Anxiety (TA) were found to exert greater work effort than those low in TA, which resulted in better sales performance. There was no relation between TA and work efficiency, measured by sales performance relative to work effort. Employees high in TA also reported greater levels of stress and more adverse effects of work on non-work relationships. Using multiple regression, both stress and interference with relationships were found to be better predicted by TA than work effort. The results are discussed in terms of laboratory-based theories about relations between TA and efficiency and intervention strategies for managing stress at work.  相似文献
