Theological thinking is influenced by perspectives on the relation of scientific knowledge to reality. Two paradigms for understanding the nature of human knowledge are considered in relation to quantum mechanics: the subjective-observing perspective of Kant, and the objective-participant perspective of Thomas Aquinas. I discuss whether quantum mechanics necessarily implies a subject centered perspective on reality, and argue, with reference to d'Espagnat's notion of veiled reality, that quantum non-separability challenges this view. I then explore whether the objective-participant perspective of Thomas Aquinas provides a more fruitful context for understanding quantum mechanics. I discuss quantum measurement in terms of the transition from potentiality to actuality, and knowledge as the latent intelligibility of the world realized. However, the negative nature of our knowledge of quantum non-separability also challenges this perspective. Our theological thinking in response to quantum knowledge must therefore proceed tentatively, balancing a via positiva, with a via negativa. 相似文献

The effects of aging on performance were examined in signal detection, letter discrimination, brightness discrimination, and
recognition memory, with each subject tested on all four tasks. Ratcliff’s (1978) diffusion model was fit to the data for
each subject for each task, and it provided a good account of accuracy and the distributions of correct and error response
times. The model’s analysis of the components of processing showed that aging had three main effects: The nondecision components
of processing were slower and the decision criteria were more conservative for 60- to 74-year-old and 75- to 85-year-old subjects
than for college students, but the quality of the evidence on which decisions were based was as good for the older subjects
as for college students on some of the tasks. Individual differences among subjects in components of processing tended to
be preserved across the tasks, as was shown by strong correlations across the tasks in the parameters of the model that represent
the components of processing. For example, if the evidence on which a subject’s decisions were based was good in one task,
it tended to be good in all four tasks. 相似文献

This investigation extends previous research documenting differences in Chinese and European American infants' facial expressivity. Chinese girls adopted by European American families, nonadopted Mainland Chinese girls, nonadopted Chinese American girls, and nonadopted European American girls responded to emotionally evocative slides and an odor stimulus. European American girls smiled more than Mainland Chinese and Chinese American girls and scored higher than Mainland Chinese girls for disgust-related expressions and overall expressivity. Adopted Chinese girls produced more disgust-related expressions than Mainland Chinese girls. Self-reported maternal strictness, aggravation, positive expressiveness, and cultural identification correlated with children's facial responses, as did number of siblings and adults in the home. Results suggest that culture and family environment influences facial expressivity, creating differences among children of the same ethnicity. 相似文献

Observers made speeded old-new recognition judgments of color stimuli embedded in a multidimensional similarity space. The paradigm used multiple lists but with the underlying similarity structures repeated across lists, to allow for quantitative modeling of the data at the individual-participant and individual-item levels. Correct-rejection response times (RTs) got systematically faster as the similarity of foils to the old study items decreased. There were also intricate patterns of speed-accuracy trade-offs that varied across individual items and participants. An exemplar-based random-walk model provided a good overall quantitative account of the recognition choice probabilities, mean correct RTs, and mean error RTs associated with the individual items on the basis of their positions in multidimensional similarity space. However, the model failed to predict the very long RTs associated with correct rejections of a prototype foil. 相似文献

Ankle inversion injuries are common, yet little is known about the error associated with different positions as inversion depth increases. In this study, absolute judgments made without feedback were used to measure discrimination of different extents of ankle inversion which arose from active movements made to physical stops by 20 self-reported right side-dominant participants. Testing was conducted over three sets of five inversion depths that were within a range of 1.4 degrees and centered around mean depths of 8,11, and 14 degrees. Discrimination of ankle inversion movements decreased linearly with depths of movement further into inversion, both within and across the sets of inversion depths. Thus, error in assessing movement position increased with inversion depth. Inversion movements that were made with the left foot were significantly better discriminated at all depths than those made with the right foot. 相似文献

In many non‐human primate species, a display of red by a female increases attraction behavior in male conspecifics. In two experiments, we investigate an analogous effect in humans, specifically, whether red on a woman's shirt increases attraction behavior in men. In Experiment 1, men who viewed an ostensible conversation partner in a red versus a green shirt chose to ask her more intimate questions. In Experiment 2, men who viewed an ostensible interaction partner in a red versus a blue shirt chose to sit closer to her. These effects were observed across participants' perceptions of their own attractiveness (Experiment 1) and general activation and mood (Experiment 2). Our findings suggest that red acts as a basic, non‐lexical prime, influencing reproduction‐relevant behavior in like manner across species. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

Personal spending predictions are sometimes optimistically biased because predictors focus on their current savings goals. The present studies explored the role of savings goals in prediction by comparing spending predictions for time periods and discrete events. Contemplating a concrete event may elicit specific goals that compete with a focus on savings goals. Consistent with this hypothesis, Studies 1 and 2 revealed that participants relied less on savings goals, and were less biased, when predicting event spending rather than weekly spending. Study 3 demonstrated the causal impact of focusing on goals that compete with savings goals: Participants induced to focus on competing goals predicted to spend more money next week, and relied less on savings goals to generate their predictions. 相似文献
