Studies of amniotic testosterone in humans suggest that fetal testosterone (fT) is related to specific (but not all) sexually dimorphic aspects of cognition and behaviour. It has also been suggested that autism may be an extreme manifestation of some male‐typical traits, both in terms of cognition and neuroanatomy. In this paper, we examine the possibility of a link between autistic traits and fT levels measured in amniotic fluid during routine amniocentesis. Two instruments measuring number of autistic traits (the Childhood Autism Spectrum Test (CAST) and the Child Autism Spectrum Quotient (AQ‐Child)) were completed by these women about their children (N=235), ages 6–10 years. Intelligence Quotient (IQ) was measured in a subset of these children (N=74). fT levels were positively associated with higher scores on the CAST and AQ‐Child. This relationship was seen within sex as well as when the sexes were combined, suggesting this is an effect of fT rather than of sex per se. No relationships were found between overall IQ and the predictor variables, or between IQ and CAST or AQ‐Child. These findings are consistent with the hypothesis that prenatal androgen exposure is related to children exhibiting more autistic traits. These results need to be followed up in a much larger sample to test if clinical cases of ASC have elevated fT. 相似文献

The current study examined the accuracy of the multiple-stimulus without replacement (MSWO) preference assessment for identifying preferred common classroom activities as reinforcers with children with behavioral disorders. The accuracy of predictions from the MSWO regarding high, medium, and low stimulus preference was tested by providing contingent access to activities for completing math problems within an independent seatwork format. Overall, there was an interaction effect between preference ranking (high, medium, or low) and number of problems completed. The results confirm and extend previous findings regarding the accuracy of predictions with the MSWO. The findings also reveal, however, some individual differences that may account for instances in which student behavior did not conform to predictions of stimulus preference assessments. 相似文献

Stress in close relationships can have significant negative consequences for mental health, physical health, and long-term relationship functioning. Dysregulated physiological responses to stress are potential pathways through which relationship stress may lead to these kinds of outcomes, and the ways in which individuals attempt to cope with relationship stress are likely to impact their physiological responses. However, our understanding of the specific coping strategies that predict physiological reactivity and recovery in these contexts is rather limited. This study explored relations between young adult college students' self-reported methods of coping with stress in their romantic relationships and their physiological reactivity to and recovery from negotiating conflict with their romantic partners. Partners' coping styles were also examined as predictors of physiological stress responses. One hundred and ninety opposite-sex couples (N = 380; modal length of relationship = 1-2 years) participated in an experimental conflict discussion task. Physiological stress reactivity to the task was assessed using salivary cortisol, a primary hormonal product of the hypothalamic-pituitary-adrenocortical (HPA) axis. Growth modeling of the cortisol levels before, during, and after the conflict task indicated that men who typically coped with relationship stress by seeking social support showed greater physiological reactivity to the conflict task. Partners' need for social support predicted stronger stress responses for both men and women, as well. While seeking social support is generally thought to be an adaptive coping strategy for couples, the results suggest that within the context of conflict negotiation in which receiving and providing support may be more difficult, seeking support from a partner is associated with greater phyisological stress. 相似文献

Perspective goals, such as studying a map to learn a route through an environment or the overall layout of an environment, produce memory congruent with the goal‐directed rather than the studied perspective. One explanation for this finding is that perspective goals guide attention towards actively gathering relevant information during learning. A second explanation is that information is automatically organized into a goal‐congruent spatial model that guides retrieval. Both explanations predict goal‐congruent memory, but only the former one predicts eye movement differences during study. The present experiment investigated the effect of perspective goals on eye movement during map study and the flexibility of resulting spatial memories. Results demonstrate eye movements towards goal‐congruent map elements during learning, and lasting memory effects at test. These findings carry implications for the design of adaptive hand‐held and in‐vehicle navigation interfaces that accommodate for varied user goals. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

Purpose Past research has shown little support for direct relationships between equity sensitivity and various equity-relevant criteria.
Recent work by Davison and Bing (J Manag Issues 20: 131–150, 2008) suggests that equity sensitivity consists of separate input-
and outcome-focus dimensions and that these dimensions are associated with such criteria in an interactive fashion. The current
study extends this research by theoretically strengthening and empirically testing their two-dimensional model.
Design/methodology/approach We surveyed adults who were working at least 30 h a week at three time periods to temporally separate measurement of predictors
and criteria (n = 172).
Findings Results provide support for the two-dimensional model. Input and outcome focus interacted to explain variance in individuals’
satisfaction and self-reported job performance even after controlling for demographic characteristics, personality, and social
desirability. By contrast, the original ESI only significantly predicted one of 10 dependent variables.
Implications Whereas a ratio has been historically used as the basis for evaluating equity, employing independent dimensions and investigating
their interaction seems more appropriate to assess individuals’ equity sensitivity. The current study suggests a multidimensional
measure of equity sensitivity may better reflect the original theoretical underpinnings of the construct.
Originality/value The current study enhances our understanding of equity theory in general, and equity sensitivity in particular, by drawing
attention to the multidimensional nature of the equity sensitivity construct. In particular, it extends the work of Davison
and Bing (J Manag Issues 20: 131–150, 2008) by revisiting Huseman et al.’s (Acad Manag Rev 12: 222–234, 1987) original conceptualization
of equity sensitivity. In doing so, we broaden its utility as a potential unique predictor of organizationally relevant criteria. 相似文献

Implications of both computer science and the computer are critical for a deeper penetration into the history of science. Building directly on “Formalized Historiography,” which appeared in this Journal last year [14 (1978): 247–263], the present essay contrasts the analysis of history of science discourse by a human reader with that at present or in prospect possible with computer-based ‘intelligent systems.’ Further, related issues are posed as to how scientific the history of science may itself become, and as to the types of transformed understanding that may emerge both of the processes of science and of the history of science. For example, would a connotation-free understanding of the structure of scientific discourse through successive state transitions (paradigm shifts) disclose science itself to be an abstract machine? 相似文献
