A Grey parrot (Psittacus erithacus), able to quantify 6 or fewer item sets (including heterogeneous subsets) by using English labels (I. M. Pepperberg, 1994), was tested on addition of quantities involving 0-6. He was, without explicit training, asked, "How many total X?" for 2 sequentially presented collections (e.g., of variously sized jelly beans or nuts) and required to answer with a vocal English number label. His accuracy suggested (a) that his addition abilities are comparable to those of nonhuman primates and young children, (b) some limits as to his correlation of "none" and the concept of zero, and (c) a possible counting-like strategy for the quantity 5. 相似文献

This study was aimed at investigating the face preference phenomenon and its underlying mechanisms at 3 months of age. Using an eye-tracker apparatus, Experiment 1 demonstrated that 3-month-olds prefer natural face images to unnatural ones, replicating and extending previous evidence obtained with schematic facelike stimuli. Experiments 2 and 3 showed that the general mechanisms that induce face preference in newborns could not explain the same phenomenon at 3 months of age, when infants are attracted by perceptual cues more specific to faces. This suggests that signs of a process of cognitive specialization are already present in 3-month-olds' visual behavior toward faces. 相似文献

To date, the literature on prayer and anxiety has yielded mixed results. Recent development of a new instrument has improved
our ability to measure individuals’ prayer activities, which may be a promising means of clarifying this literature. This
correlational study examined preferred prayer styles and associated scores on measures of anxiety control and trait anxiety
in a sample of 85 college students. Results suggested that individuals whose prayer styles were characterized by active rather
than avoidant coping were likely to evidence greater perceived control of anxiety and lower levels of trait anxiety.

This article examines how the human visual system represents the shapes of 3-dimensional (3D) objects. One long-standing hypothesis is that object shapes are represented in terms of volumetric component parts and their spatial configuration. This hypothesis is examined in 3 experiments using a whole-part matching paradigm in which participants match object parts to whole novel 3D object shapes. Experiments 1 and 2, consistent with volumetric image segmentation, show that whole-part matching is faster for volumetric component parts than for either open or closed nonvolumetric regions of edge contour. However, the results of Experiment 3 show that an equivalent advantage is found for bounded regions of edge contour that correspond to object surfaces. The results are interpreted in terms of a surface-based model of 3D shape representation, which proposes edge-bounded 2-dimensional polygons as basic primitives of surface shape. 相似文献

We investigated how both objective and subjective organizations affect perceptual organization and how this perceptual organization, in turn, influences observers’ performance in a localization search task. Two groups of observers viewing exactly the same stimuli (objective organization) performed in significantly different ways, depending on how they were induced to parse the display (subjective organization). In Experiments 1 and 2, the observers were asked to describe the location of a tilted target among a varying number of vertical or horizontal distractors. Subjective organization was induced by instructing observers to parse the display into either three horizontal regions (rows) or three vertical regions (columns). The position of the target was critical: location performance, as assessed by reaction time and errors, was consistently impaired at the locations adjacent to the boundaries defining the regions, producing what we refer to as thesubjective boundary effect. Furthermore, the extent of this effect depended on whether the stimulus-driven and conceptually driven information concurred or conflicted. This made location information more or less accessible. In Experiment 1, the strength of objective grouping was a function of the proximity of the items (near or far conditions) and their orientation in a 6×6 matrix. In Experiment 2, the strength of objective grouping was a function of similarity of color (items were color coded by rows or by columns) and the orientation of the items in a 9×9 matrix. The subjective boundary effect was more pronounced when the display promoted grouping in the direction orthogonal to that of the task (e.g., when observers parsed by rows but vertical distractors were closer together [Experiment 1] or color coded [Experiment 2] to induce global columns). In contrast, this effect decreased when the direction of both objective and subjective organizations was parallel (e.g., when observers parsed by rows and horizontal distractors were closer together [Experiment 1] or were color coded [Experiment 2] to induce global rows). A localization search task proved to be an ideal forum in which objective and subjective organizations interacted. We discuss how these results indicated that observers’ performance in a localization task was determined by the interaction of objective and subjective organizations, and that the resulting perceptual organization constrained coarse location information. 相似文献

Australian students' attitudes to nuclear weapons were considered in relation to sex-role identification and political orientations. By including a measure of sex-role orientation, we hoped to clarify earlier confusion surrounding gender as a predictor of nuclear views. Our hypothesis was that men and women with feminine sex-role orientations would display the strongest antinuclear feelings. Also, we predicted that an authoritarian political stance advocating strict law-and-order on the domestic front would predict support for nuclear weapons in international defense. The subjects were 46 male and 62 female first-year university students. The measure of nuclear attitudes was a 23-item inventory (NARQ) which had previously been extensively refined and validated for Australian populations (Jennings & Lawrence, 1986). The BSRI (Bem, 1974) measured sex-role orientation. An Australian law-and-order scale was also developed for this research. Latent trait models for rating data were applied to NARQ and law-and-order scales. The results revealed sex differences on approximately one-third of the nuclear opinion items, with men expressing stronger support for nuclear weapons in every case. Authoritarian law-and-order attitudes likewise predicted support for nuclear weapons in both men and women. A stepwise multiple regression analysis showed that BSRI masculinity and law-and order made separate, statistically significant, contributions to overall variation in nuclear views. These results were considered in relation both to previous research and to practical implications for political behavior. 相似文献

Positive effects for women and girls of all-female schools have been proposed, although there is relatively little clear empirical support for these beneficial results. Much of the cited research is based on elite all-female institutions or on parochial schools. This study takes advantage of the change of a private, nonparochial school from all girls to both sexes. Longitudinal data from grades 2 through 12 were collected over the course of the academic year to study the results of this transition. Stereotyping declined with age and over time in both types of class-rooms. Girls in single-sex classrooms showed some tendency to be more stereotyped in their perceptions of mixed-sex classrooms than did the girls who were actually in that setting. Thus, none of the measures showed any significant increase over time in stereotyping among girls in mixed-sex classes. Implications of these findings are discussed. 相似文献
