Klaas J. Kraay argues that the rational choice model for divine creation—according to which God chooses to actualize one world among possible alternatives based on its axiological properties—cannot succeed given failures of comparability across possible worlds. I argue that failure of comparability across worlds would not undermine the rationality of choosing one world to create among possible alternatives. 相似文献

The effects of a background scene on the perception of the trajectory of an approaching object and its relation to changes in angular speed and angular size were examined in five experiments. Observers judged the direction (upward or downward) of two sequentially presented motion trajectories simulating a sphere traveling toward the observer at a constant 3-D speed from a fixed distance. In Experiments 1–4, we examined the effects of changes in angular speed and the presence of a scene background, with changes in angular size based either on the trajectories being discriminated or on an intermediate trajectory. In Experiment 5, we examined the effects of changes in angular speed and scene background, with angular size either constant or consistent with an intermediate 3-D trajectory. Overall, we found that (1) observers were able to judge the direction of object motion trajectories from angular speed changes; (2) observers were more accurate with a 3-D scene background, as compared with a uniform background, suggesting that scene information is important for recovering object motion trajectories; and (3) observers were more accurate in judging motion trajectories based on angular speed when the angular size function was consistent with motion in depth than when the angular size was constant. 相似文献

Interpolation across orientation discontinuities in simulated three-dimensional (3-D). surfaces was studied in three experiments with the use of structure-from-motion (SFM). displays. The displays depicted dots on two slanted planes with a region devoid of dots (a gap). between them. If extended through the gap at constant slope, the planes would meet at a dihedral edge. Subjects were required to place an SFM probe dot, located within the gap, on the perceived surface. Probe dot placements indicated that subjects perceived a smooth surface connecting the planes rather than a surface with a discontinuity. Probe dot placements varied with slope of the planes, density of the dots, and gap size, but not with orientation (horizontal or vertical). of the dihedral edge or of the axis of rotation. Smoothing was consistent with models of 2-D interpolation proposed by Ullman (1976). and Kellman and Shipley (1991). and with a model of 3-D interpolation proposed by Grimson (1981). 相似文献

As part of a larger study of birth order, sex of child, and mother—child interaction, mothers were asked to supervise their child's performance on memory and puzzle tasks. Subjects were 56 5-year-old boys and girls and their mothers, half with a same-sex older sibling, half with a same-sex younger sibling. Mothers showed no differences in spontaneous help-giving as a function of sex or birth order of child, but were more likely to give requested help and support to daughters than sons, and to respond contingently to daughters' mistakes. Implications of greater reinforced help-seeking for girls' orientations to achievement and problem-solving are considered.The work for this study was financed in part by Public Health Service Predoctoral Fellowship 5F1MH20, 971-02 and Special Fellowship 1-F03-HD-49722-01 from the National Institutes of Health. The authors wish to express gratitude for the assistance of Dan Eisenberg in performing data analysis.Portions of this paper were presented at meetings of the Western Psychological Association, San Francisco. 1974. 相似文献

Two studies are reported which examined physiological responsiveness to changes in level of nonverbal intimacy cues expressed by a partner during an interview conducted across interactive television. Experiment 1 and Experiment 2 separately examined the effects of decreasing apparent interactive distance (produced by alteration of image size) and increasing eye-contact on subjects' heart rate and pulse amplitude. The findings suggest that shifts in these nonverbal approach cues are related to cardiovascular changes including bradycardia and a modest compensatory increase in pulse amplitude. The implications of these results are discussed in terms of the hypothesized relationship between cardiovascular functioning and information processing and practical considerations for the use of interactive television. 相似文献

To assess the effects of affective orientation on the judgment of facial attriutes, 165 subjects were asked to make judgments of the attributes of each of two faces. For each face, subjects were either given no information about the person in the photo, or were given biographical information connoting either a favorable or unfavorable personality. It was predicted that when subjects make judgments along dimensions that were evaluatively loaded (e.g., smilling vs frowning mouth), manipulated attitude would influence these judgments. For the seven dimensions rated by the subjects, four dimensions showed the predicted effect. The other three dimensions, which did not show the effect, were the only ones that showed a significant effect due to the face itself. It was concluded that for dimensions that are not highly structured by the characteristics of the face, attitude can significantly influence judgments of facial attributes. 相似文献

We investigated the influence of social-cognitive factors on students' success on college entrance exams in South Korea. Subjects were 291 college freshmen attending either a prestigious or a less prestigious college. They completed a self-report questionnaire assessing perceived parental control, fear of failure, anxiety, self-efficacy, and time management skills. The results showed that parental psychological control had debilitating effects and self-efficacy had facilitating effects on the performance on the college entrance exam for all students. Fear of failure positively influenced the performance of the students in the less prestigious college but not in the more prestigious college. In addition, comparison of the two colleges revealed that students attending the prestigious college used better time management skills than students attending the less prestigious college. Further, students in the prestigious college tended to be from families with a higher SES level than students attending the less prestigious college. Information is provided to students, parents, and teachers regarding alternative methods for preparing for college entrance exams. 相似文献
