Many studies have documented systematic shifts in women’s mate preferences and sexual motivations across the ovulatory cycle. Harris (2012) presents a nonreplication of one particular finding in this literature—namely, that women’s preference for masculinity in men’s faces shifts across the cycle. Harris critiques the empirical and theoretical literature on cycle shifts and concludes that the cycle shift hypothesis should be abandoned. Here, we situate Harris’s findings within the broader empirical literature and respond to several of the points in her critique. We conclude that the evidence for cycle shifts in women‘s mate preferences and sexual motivations is much stronger than Harris portrays and that she mischaracterizes the theoretical basis of this work.  相似文献

True independence is difficult for young adults to achieve by leaving home due to economic austerity and contemporary expectation. Such extended dependence has, however, been little studied. Midlife mothers were interviewed to explore their experience of having their adult sons live at home. The interviews were analysed using Grounded Theory (Strauss and Corbin in Basics of qualitative research: grounded theory procedures and techniques. Sage, Newbury Park, CA, 1990). The essence of the mothers’ (n = 5) experience was captured in the core category, Coming to Terms and Entering a New Phase. This category integrates the three-stage model of process that occurred as mothers accepted that their maternal role was changing and they needed to prepare for the next stage of their lives. The three stages were represented by the subcategories, Shifting Role, Anticipating Loss and Letting Go. The women believed that their sons would not be able to leave home until they could purchase a property, a distant prospect for many. The findings extend the work of previous lifespan models, including that of Apter (Secret paths: women in the new midlife. W. W. Norton, New York, 1995) but with greater depth and clarity, in a vital and changed contemporary context that is likely to be relevant for a large population of women.  相似文献

Behaviors characteristic of autism and ADHD emerge in early childhood, yet research investigating their comorbidity has focused on older children. This study aimed to explore the nature of the relationship between autistic-like traits and ADHD behaviors in a community sample of 2-year-olds. Twins from the Boston University Twin Project (N = 312 pairs) were assessed by their parents on autistic-like traits and ADHD behaviors using the Childhood Behavior Checklist. Phenotypic analyses showed that after controlling for general cognitive ability and socioeconomic status, autistic-like traits (total scale as well as social and nonsocial subscales) correlated positively with ADHD behaviors (r = 0.23–0.26). Structural equation model-fitting analyses revealed that there were modest shared genetic influences between ADHD- and autistic traits (genetic correlation = 0.27) as well as some common environmental influences explaining their covariation. Implications for identifying shared biological pathways underlying autistic-like traits and ADHD behaviors are discussed.  相似文献

A multimodal person representation contains information about what a person looks like and what a person sounds like. However, little is known about how children form these face-voice mappings. Here, we explored the possibility that two cognitive tools that guide word learning, a one-to-one mapping bias and fast mapping, also guide children's learning about faces and voices. We taught 4- and 5-year-olds mappings between three individual faces and voices, then presented them with new faces and voices. In Experiment 1, we found that children rapidly learned face-voice mappings from just a few exposures, and furthermore spontaneously mapped novel faces to novel voices using a one-to-one mapping bias (that each face can produce only one voice). In Experiment 2, we found that children's face-voice representations are abstract, generalizing to novel tokens of a person. In Experiment 3, we found that children retained in memory the face-voice mappings that they had generated via inference (i.e., they showed evidence of fast mapping), and used these newly formed representations to generate further mappings between new faces and voices. These findings suggest that preschoolers' rapid learning about faces and voices may be aided by biases that are similar to those that support word learning.  相似文献

We investigated potential gender differences in video game (pong) performance in university students. In Experiment 1 men (N = 16) performed significantly better than women (N = 16). Experiment 2 was similar to the first, but used 14 men and 14 women who were matched carefully on previous video game experience. In spite of the matching, results replicated those of the first experiment. In Experiment 3 we evaluated the effect of an audience (male, female, none) on pong performance in 42 men and 42 women. We also assessed trait competition anxiety (Sport Competition Anxiety Test scores), sex role identification (Bem Sex Role Inventory scores), and video game experience. Both genders showed significantly poorer performance when they played pong in the presence of a female audience. Overall, males outperformed females as in the first two experiments. Examination of individuals with low, medium, and high levels of sport competition anxiety and videogame experience reveals persistent gender differences in performance, seemingly independent of levels of anxiety and experience. In all three experiments, both men and women showed significant improvement in performance over trials.  相似文献

Extinction and reinforcement contingencies were used to treat 2 children with feeding disorders. Positive reinforcement and avoidance extinction effectively increased food acceptance but also increased food expulsion. Reduced expulsion and increased swallowing were achieved by repeated presentation of expelled food, a second extinction component.  相似文献

In this paper, I offer a treatment of “the clinic” in which the clinic—as concept and space—is que(e)ried, that is, both questioned and made queer. I present two historical case studies that queer clinical thought and practices in the period before AIDS and before the full-blown arrival of queer theory on the western theoretical landscape. These two cases—the practice of self-help developed in the women’s health movement in the United States and the practice of tranversality developed out of and beyond the Institutional Psychiatry movement in France—challenge the practice of medicine in the prehistory of both AIDS and queer theory, yet, they are not generally seen as precursors, or related in any way, to AIDS activism. In a sense, then, I also want to question and make queer the history of AIDS as we conventionally know it today by extending that history backwards and outwards to earlier queer critical and clinical practices like self-help and transversality.  相似文献

One desired outcome of inclusive education is the enhanced social development of students with disabilities. Some have suggested that planned and systematic support of students with severe disabilities in general education environments may lead to greater social interaction between these students and their peers without disabilities. In an effort to analyze this proposition, we studied two students with severe disabilities as they began participating in general education classrooms. Using within-student multiple baseline designs across class periods, the effects of participating in general education were studied across a range of social participation indicator variables. Our results suggest that planned and systematic efforts to include students with severe disabilities into general education courses can have positive effects on their social contacts and friendship networks. Our findings are discussed in relation to policy efforts to establish inclusive education in public schools, strategies for structuring general education participation, and the potential effects such efforts can have on the social inclusion of students with disabilities.  相似文献

In light of the nine open peer commentaries, we further explicate the social projection model and highlight its boundaries. We acknowledge that our model—like any extant model—cannot account for all the available empirical data. Yet the model is strong because it explains cooperation in a variety of social dilemmas and experimental games while deploying only one psychological construct as a parameter. Compared with its competitors, the social projection model more openly recognizes the struggle with uncertainty a person caught in a social dilemma must confront. In a series of simulations (and brute math), we show that cooperation can survive when players (humans) stay the Bayesian course.  相似文献
