The integration of binocular stereopsis and kinetic depth was measured for two distinct aspects of 3-Dstructure: (1)shape index, which is a measure of scale-independent structure, and (2)curvedness, which is a measure of scale-dependent structure. We found that motion contributes significantly more to judged shape index than it does to judged curvedness, and stereo contributes significantly more to judged curvedness than it does to judged shape index. This suggests that the differences in the relative contribution of motion and stereo reported here occurred because these two sources do not equally specify the scale-dependent and scale-independent aspects of surface structure. Furthermore, these results seem to be inconsistent with integration models in which the different visual cues all initially contribute to the same single representation of 3-Dstructure. 相似文献

An advantage of first mention—that is, faster access to participants mentioned first in a sentence—has previously been demonstrated only in English. We report three experiments demonstrating that the advantage of first mention occurs also in Spanish sentences, regardless of whether the first-mentioned participants are syntactic subjects, and regardless, too, of whether they are proper names or inanimate objects. Because greater word-order flexibility is allowed in Spanish than in English (e.g., nonpassive object-verb-subject constructions exist in Spanish), these findings provide additional evidence that the advantage of first mention is a general cognitive phenomenon. 相似文献

Four experiments investigated observers’ judgments of rigidity for different types of optical motion. The depicted structural deformations were of two types: (1) those with nonparallel image trajectories that are detectable from the first-order spatiotemporal relations between pairs of views; and (2) those with parallel image trajectories that can only be detected from higher order relations among three or more views. Patterns were composed of smooth flow fields in Experiments 1 and 3, and of wire frame figures in Experiments 2 and 4. For both types of display, the nonrigidity detectable from the first-order spatiotemporal structure of the motion sequence was much more salient than the deformation detectable only from the higher order spatiotemporal structure. These results indicate that observers’ judgments of rigidity are based primarily on a two-view analysis, but that some useful information can be obtained under appropriate circumstances from higher order spatiotemporal relations among three or more views. 相似文献

There are several studies suggesting that the Social Performance Survey Schedule (SPSS) is a reliable and valid measure of social skill. However, the factorial structure of the SPSS has never been examined. In the present study, SPSSs taken by 652 college students were factor analyzed by the method of principal components and the resulting factors were rotated according to the varimax criterion. Separate factor analyses were conducted for men and women. Seven factors, which accounted for a little over a third of the total variance, were retained for each sex. A large general factor labeled Prosocial Competence emerged for both sexes. Beyond this, the factorial solutions for the two sexes tended to diverge, with males showing a large negative factor (Social Offensiveness) and three smaller negative factors and females showing five relatively small negative factors. Suggestions were made concerning additional factor analytic studies of the SPSS and the ways in which derived factors might be used in research and clinical work.This research was supported by funds from the Rutgers University Research Council.

A 32-year-old male volunteer with an eight year history of chronic unilateral tinnitus (ear-ringing) participated in a behavioral assessment strategy that included a series of measurement and modification procedures. A psychophysical matching technique was employed throughout a planned combination of procedures to assess and manipulate the intensity or loudness of tinnitus responses. Following baseline assessment, measurements were conducted at varying times of the day, concomitant with exposure to music, during progressive relaxation training, and under conditions of caffeine consumption. The value of careful assessment to describe cues and conditions associated with tinnitus and its reduction are discussed with implications for behavior treatment design and evaluation. 相似文献

Two experiments are reported in which observers had to utilize information from one of two structural levels of visual stimulus patterns (large letters composed of smaller ones). They could utilize information more rapidly form one level only at the cost of slower utilization from the other. This trade off defines an empirical attention operating characteristic (AOC) which is consistent with a simple mathematical model of the perceptual process: when viewing a stimulus, the observer selects one of two alternative “attentional” strategies, where each strategy is optimal for utilizing information from one structural level, but less than optimal for the other. 相似文献

The present study compares the effects of two different socialization environments—the Israeli kibbutz and the city—on the social values held by 16-17 year-olds. A total of 352 boys and girls, 195 porn the city and 157 porn the kibbutz, filled out a specially prepared thirteen-item questionnaire on social values. The results revealed the existence of four factors underlying these values: self-oriented concerns (factor 1), other-oriented concerns (factor 2), reliance on innate spiritual capacities (factor 3), reliance on physical and productive capacities (factor 4). Significant differences on factors 1 and 3 were uncovered for the kibbutz and the city subjects, while boys and girls differed significantly on factors 2 and 4. The findings were discussed in light of the differences in educational systems between the kibbutz and the city, and in light of sex-role differences characteristic of Western society in general. 相似文献

This research examined gender differences in orientations toward autonomous and social achievement. Three independent samples of subjects (total N= 359 males and 574 females) completed measures of achievement orientation (including Strumpfer's [1975] Autonomous Achievement Values and Social Achievement Values scales) and relevant cognitive, affective, and behavioral variables. Correlational and factor analyses clearly identified distinct autonomous and social achievement factors for both men and women in each of the samples. Examination of the correlates of achievement orientation indicated that whereas an autonomous achievement orientation is similarly expressed in males and females, there are considerable sex differences in the expression of an orientation toward social achievement. In particular, a social achievement orientation was associated with concerns over social approval and responsiveness to social influence among males, but was generally unrelated to these factors among females. Findings are discussed in terms of several recent hypotheses concerning the effects of sex role norms on the development and expression of achievement needs in men and women. 相似文献

The Children's Depression Index (CDI) was administered to a group of 304 regular school students in Grades 3–12. It was found that 21% of the students reported mild to moderate levels and 7% reported severe levels of depression. Females reported more overall depression than did males. Specific CDI items selected more frequently by females than by males supports previous work suggesting that females tend to internalize difficulties whereas males are more likely to externalize problems. There were no age differences associated with overall depression; however, there were some developmental differences in specific items cited. Finally, “red flags” were identified that may be helpful in spotting children suffering from severe levels of depression. 相似文献
