Central to Augustine's understanding of rightly ordered sexuality is his belief that the pleasure of the act should not be separated from its good (procreation). It is useful to observe that he reasons in a similar way about eating: that the pleasure of eating should not be separated from its good (nourishment). Inadequacies in his understanding of the purpose of food and eating may be instructive when we think about inadequacies in his understanding of sex. If there is more to food than he imagines, the same may be true of sex. Correcting for such inadequacies may also help correct for the (inadvertent) way in which his understanding of the purpose of sex may seem to legitimize technologies of assisted reproduction. 相似文献

Reproductive activity has been the behavior of choice for research in behavioral endocrinology. Why this is so and the consequences to the study of aggression and to behavioral endocrinology in general are explored. 相似文献

The social relations of three adult males in a captive chimpanzee group were evaluated for 12 months. The observations encompassed a period of transition in the dominance hierarchy providing an opportunity to assess behavioral patterns involved in the initiation of status changes. This study shows that dominance in the chimpanzee is expressed primarily through ritualized and non-contact behavior rather than by overt aggression. In particular, display behavior is important for indicating dominance rank, in communicating aggressive intent, and as a prelude to status struggles. The functional relationships between status, displays and other socio-sexual behavior patterns are presented. 相似文献

In this article, I urge that mainstream discussions of abortion are dissatisfying in large part because they proceed in polite abstraction from the distinctive circumstances and meanings of gestation. Such discussions, in fact, apply to abortion conceptual tools that were designed on the premiss that people are physically demarcated, even as gestation is marked by a thorough-going intertwinement. We cannot fully appreciate what is normatively at stake with legally forcing continued gestation, or again how to discuss moral responsibilities to continue gestating, until we appreciate in their own terms the goods and evils distinctive of gestational connection. To underscore the need to explore further the meanings of gestation, I provide two examples of the difference it might make to legal and moral discussions of abortion if we appreciate more fully that gestation is an intimacy. 相似文献

The spatial‐temporal association indicates that time is represented spatially along a left‐to‐right line. It is unclear whether the spatial‐temporal association is mainly related to a perceptual or a motor component. In addition, the spatial‐temporal association is not consistently found using a time reproduction task. Our rationale for this finding is that, classically, a non‐lateralized button for performing the task has been used. Using two lateralized response buttons, the aim of the study was to find a spatial‐temporal association in a time reproduction task. To account for the perceptual component, reference and target stimuli were presented in different spaces through four experiments. In all experiments, a Spatial‐Temporal Association of Response Codes (STEARC) effect was found and this effect was not modulated by the spatial position of both reference and target stimuli. The results suggested that the spatial‐temporal association was mainly derived from the spatial information provided by response buttons, reflecting a motor but not visuospatial influence. 相似文献

People have a tendency to organize space by extracting meaningful shapes from the configuration of elements. However, research on spatial correspondence in children suggests that when configural processing is difficult, individuation of elements may be critical. To begin to address the distinction between the use of configurations and individuation, and changes associated with age, we relied upon perceptual grouping and manipulated the colour of the displays—promoting either extraction of configural information (monochromatic) or individuation of elements (multicoloured). In a layout reproduction task (Experiments 1 and 2), children showed a robust advantage for multicoloured arrays, whereas adults showed an attenuated advantage for monochromatic displays. Visual discrimination in adults (Experiment 3) revealed that the influence of the display type occurs at the level of perception. Taken together, these results suggest that there are (at least) two routes to establishing spatial correspondence in arrays of elements, with differential dependence over development. 相似文献

This study aimed to investigate what conditions can lead to a bias for communicating stereotype inconsistent (SI) information, relative to stereotype consistent (SC) information. Sixty‐three undergraduate university students (22 males, 41 females; Mage = 21.25) read a story about an Arab man who exhibited characteristics consistent and inconsistent with the stereotype of Arab men. The story was transmitted through 21 three‐person communication chains; each participant rewrote the story from memory for the next person in the chain to read, with only the first participant in each chain reading the original story. As hypothesized, when a surprising category conjunction was formed by pairing the primary stereotype (Arab men) with a secondary stereotype of a contradictory nature (kindergarten teachers), SC information was circulated less than SI information. This was also the case when a causal explanation was provided that accounted for the unexpected SI information. Findings indicate the potential of techniques that elicit cognitive elaboration of SI information to encourage an SI bias in communication, and show promise for exploring ways to reduce the impact of negative stereotypical information in the long term. 相似文献

Research on the mental representation of time (‘subjective time’) has provided broad insights into the nature of time perception and temporal processing. As the field comprises different scientific disciplines, such as psychology, philosophy, and neuroscience, studies differ with regard to the basic terms and concepts used. For this reason, research on subjective time lacks a coherent conceptual system. We argue that research in the field of subjective time should aim at establishing such a system, i.e., a more standardized terminology, in order to strengthen its theoretical basis and to support an efficient communication of results. Based on key empirical findings and concepts that are commonly (but inconsistently) used in the literature, we argue for a conceptual framework for the study of subjective time that differentiates between three types of mental representations of time: basic temporal processing, time perception in terms of passage, and time perception in terms of duration. 相似文献
