Although little is known about how preferences develop in childhood, work in adults suggests that evaluative responses to stimuli can be acquired through classical conditioning. In two experiments children were exposed to novel cartoon characters, that were either consistently paired with a picture of a disliked food (Brussels sprouts) or a liked food (ice cream). Relative preferences for these stimuli (and others) were measured before and after these paired presentations (Experiment 1): preferences for the cartoon character paired with Brussels sprouts decreased, whereas preferences for the character paired with ice cream increased. These preferences persisted after 10 un-reinforced trials. Experiment 2 replicated this finding using affective priming as an index of preference for the cartoon characters. These findings demonstrate that preferences to novel stimuli can be conditioned in children and result from associations formed between the stimulus and a stimulus possessing positive or negative valence. 相似文献

Why do sexually appealing women often attract derogation and aggression? According to terror management theory, women's sexual allure threatens to increase men's awareness of their corporeality and thus mortality. Accordingly, in Study 1 a subliminal mortality prime decreased men's but not women's attractiveness ratings of alluring women. In Study 2, mortality salience (MS) led men to downplay their sexual intent toward a sexy woman. In Study 3, MS decreased men's interest in a seductive but not a wholesome woman. In Study 4, MS decreased men's but not women's attraction to a sexy opposite-sex target. In Study 5, MS and a corporeal lust prime increased men's tolerance of aggression toward women. Discussion focuses on mortality concerns and male sexual ambivalence. 相似文献

Autism is the most commonly studied of a spectrum of developmental disorders that are believed to be neurobiologically based but which, at this point, for lack of good biomarkers, are defined purely by behavior. In the last 20 years, the definition of autism has shifted in emphasis from extreme aloofness and positive signs of abnormality in repetitive and sensorimotor behaviors to a greater awareness of the importance of more subtle reciprocal social communication deficits as core features. Standard diagnostic instruments were developed for research purposes to acquire information both through caregiver interviews and direct clinical observation. Use of these instruments in clinical practice resulted in major improvements, which in turn affected research results. These results yielded further improvements that led to changes in clinical practice over time. The synergism between research and clinical practice in the understanding of autism is discussed. 相似文献

This study investigated whether children's fears could be un-learned using Rachman's indirect pathways for learning fear. We hypothesised that positive information and modelling a non-anxious response are effective methods of un-learning fears acquired through verbal information. One hundred and seven children aged 6-8 years received negative information about one animal and no information about another. Fear beliefs and behavioural avoidance were measured. Children were randomised to receive positive verbal information, modelling, or a control task. Fear beliefs and behavioural avoidance were measured again. Positive information and modelling led to lower fear beliefs and behavioural avoidance than the control condition. Positive information was more effective than modelling in reducing fear beliefs and both methods significantly reduced behavioural avoidance. The results support Rachman's indirect pathways as viable fear un-learning pathways and supports associative learning theories. 相似文献

This paper examines Spinoza's remarks on women in the Political Treatise in the context of his views in the Ethics about human community and similitude. Although these remarks appear to exclude women from democratic participation on the basis of essential incapacities, I aim to show that Spinoza intended these remarks not as true statements, but as prompts for critical consideration of the place of women in the progressive democratic polity. In common with other scholars, I argue that women, in Spinoza's system, are deprived of freedom and political participation not by their essential natures, but by their social and historical circumstances. I differ from other scholars, however, in basing this conclusion on the different critical functions of the Political Treatise and the Ethics. Following that critical comparison, I consider Spinoza's views on the `natural right' of women and their equal capacity for political participation in terms of his arguments for the compositional similarity of men and women. Finally, I argue that Spinoza offers an explanation for women's actual disempowerment through his account of economic dependence within marriage. 相似文献

Cellular precipitation (also known as discontinuous precipitation) has been observed at the grain boundaries of a newly developed nickel-based Inconel740H alloy designed for use at 700?°C in advanced ultrasupercritical coal-fired power plants. By means of element mapping and selected area diffraction, the cellular precipitates were identified as Cr-rich M23C6 carbides. The onset of cellular precipitation was found to follow a pucker mechanism in Inconel740H. The cellular precipitates at the grain boundaries, even at low volume fractions, were severely detrimental to the creep strength at 750?°C. The creep rupture life of Inconel740H containing cellular precipitates at grain boundaries was only one-tenth of that for the alloy without cellular precipitates. The reason for the drastically decreased creep rupture life is attributed to the poor resistance of cellular precipitates to crack propagation during creep. 相似文献

This study provided a systematic qualitative examination of robust sport-confidence. A focus group (2 male and 2 female participants), and follow-up interviews, with 16 (8 male and 8 female participants) elite individual sport performers, were conducted to define and contextualize the characteristics of robust sport-confidence. Data analysis procedures resulted in a definition of robust sport-confidence and the identification of 6 characteristics of robust sport-confidence. The characteristics abstracted were: multidimensional, malleable, durable, strength of belief, developed, and protective. Overall, robust sport-confidence was conceptualized as a multidimensional set of enduring positive beliefs. Future research and practical implications are discussed. 相似文献

ObjectivesThere is growing evidence that mindfulness has positive consequences for both psychological and physical health in both clinical and non-clinical populations. The potential benefits of mindfulness underpin a range of therapeutic intervention approaches designed to increase mindfulness in both clinical and community contexts. Self-guided mindfulness-based interventions may be a way to increase access to the benefits of mindfulness. This study explored whether a brief, online, mindfulness-based intervention can increase mindfulness and reduce perceived stress and anxiety/depression symptoms within a student population.MethodOne hundred and four students were randomly allocated to either immediately start a two-week, self-guided, online, mindfulness-based intervention or a wait-list control. Measures of mindfulness, perceived stress and anxiety/depression were administered before and after the intervention period.ResultsIntention to treat analysis identified significant group by time interactions for mindfulness skills, perceived stress and anxiety/depression symptoms. Participation in the intervention was associated with significant improvements in all measured domains, where no significant changes on these measures were found for the control group.ConclusionsThis provides evidence in support of the feasibility and effectiveness of shorter self-guided mindfulness-based interventions. The limitations and implications of this study for clinical practice are discussed. 相似文献
