We prospectively examined the relationship between individuals' belief in a just world and their desire for revenge against the perpetrators of the September 11 terrorist attacks against the United States. Eighty-three undergraduate students who had completed a measure of just-world beliefs prior to the terrorist attacks were assessed approximately 2 months following the attacks. The more strongly they had endorsed just-world beliefs prior to the attacks, the more distressed they felt about the attacks and the more they desired revenge. Furthermore, the relationship between belief in a just world and the desire for revenge was mediated by feelings of distress in response to the terrorist attacks. The results point to the importance of justice beliefs in understanding responses to the terrorist attacks. 相似文献

The World-Wide Web offers a potentially interesting tool to collect data from a large and heterogeneous audience. While questionnaires have become rather common on the Internet, its potential reaches far beyond text processing. In principle, it is possible not only to perform interactive, dynamic experiments on the Web, but also to include graphical animation and time-critical responses, such as reaction times. We implemented a visual motion extrapolation task on the Web using the programming language Java, which can be interpreted by standard Web browsers such as Netscape or Internet Explorer. The data collected with this method turned out to be reliable and differed little from data obtained in a controlled laboratory setting, with the exception of conditions with fixation instruction. Thus, the Web can, generally speaking, be used for data collection of large sample sizes. The strengths and weaknesses of dynamic visual simulation experiments on the Internet are discussed. 相似文献

Summary A rewrite-rule text grammar was used to predict question asking. Subjects were instructed to write a text according to a known format, i.e., a police report calling for witnesses to an accident, but first they had to find out what had occurred by asking questions. Each question was answered immediately. The results indicate that the established text grammar predicted the content of the questions well, but did not predict their sequence. Deviations from the predictions are discussed in terms of question-asking strategies as evolved from a text grammar. 相似文献

Kaiser's measure of sampling adequacy is applied to a special Spearman matrix and a specialq-cluster generalization. The result supports the contention that the measure should be no less than .5 for data to be appropriate for factor analysis.The research reported in this note was supported in part by the Program in Applied Mathematics and Statistics, National Science Foundation, and by the National Institute of Education, Department of Health, Education, and Welfare. 相似文献

The assumption that humans are able to perceive and process angular kinematics is critical to many structure-from-motion and optical flow models. The current studies investigate this sensitivity, and examine several factors likely to influence angular velocity perception. In particular, three factors are considered: (1) the extent to which perceived angular velocity is determined by edge transitions of surface elements, (2) the extent to which angular velocity estimates are influenced by instantaneous linear velocities of surface elements, and (3) whether element-velocity effects are related to three-dimensional (3-D) tangential velocities or to two-dimensional (2-D) image velocities. Edge-transition rate biased angular velocity estimates only when edges were highly salient. Element velocities influenced perceived angular velocity; this bias was related to 2-D image velocity rather than 3-D tangential velocity. Despite these biases, however, judgments were most strongly determined by the true angular velocity. Sensitivity to this higher order motion parameter was surprisingly good, for rotations both in depth (y-axis) and parallel to the line of sight (z-axis). 相似文献

Brain-computer communication: unlocking the locked in 总被引:7,自引:0,他引:7
With the increasing efficiency of life-support systems and better intensive care, more patients survive severe injuries of the brain and spinal cord. Many of these patients experience locked-in syndrome: The active mind is locked in a paralyzed body. Consequently, communication is extremely restricted or impossible. A muscle-independent communication channel overcomes this problem and is realized through a brain-computer interface, a direct connection between brain and computer. The number of technically elaborated brain-computer interfaces is in contrast with the number of systems used in the daily life of locked-in patients. It is hypothesized that a profound knowledge and consideration of psychological principles are necessary to make brain-computer interfaces feasible for locked-in patients. 相似文献

Overreliance on one measurement approach can challenge accurate statements about reality, as findings can represent by‐products of the compulsory measurement paradigm. Within the theory of planned behavior (TPB), the compatibility principle represents one such strictly imposed paradigm. Using 2 cross‐sectional surveys of 1,394 volunteers and involving structural equation models, we demonstrate that the widely employed practice of measuring TPB constructs is confounded with method‐implied bias. This means the theory cannot conclusively reveal origins of a behavior. Our results also suggest that on an aggregated level, when method bias is eliminated, its constructs are linked in hypothesized ways. Adopting a more general model—thus, adopting a more traitlike conceptualization of attitudes—has interesting implications for social psychology and its current trends. 相似文献

Analogue Mental Transformations in 3‐Year‐Olds: Introducing a New Mental Rotation Paradigm Suitable for Young Children 下载免费PDF全文
Markus Krüger Marlen Kaiser Kristin Mahler Wolfgang Bartels Horst Krist 《Infant and child development》2014,23(2):123-138
Until now, a successful application of the mental rotation paradigm was restricted to children 5 years or older. By contrast, recent findings suggest that even infants can perform mental rotation. Unlike the methods used in infant studies (looking time), our new research paradigm allows for the measurement and interpretation of reaction times. Kindergartners (aged 3–6 years) were presented with a stimulus configuration on a touchscreen and asked to bring a rotated stimulus into an upright position using the shortest path. Mean reaction time (RT) increased linearly with angular disparity. The ensuing linear trend was significant not only for the entire sample but also for the youngest age group analysed separately. To exclude the possibility that linearity was due to movement planning, 3‐year‐olds had to manually rotate a stimulus about the same trajectory without the need for a corresponding mental transformation in a second experiment. Here, no linear trend was observed. These results are interpreted as evidence for an analogue mental transformation in 3‐year‐olds, equal to the transformation processes in older children's and adults' mental rotation.

Do women who succeed in male‐dominated domains help other women? The moderating role of gender identification 下载免费PDF全文
It is often expected that the first women to advance in male‐dominated fields will promote other women who follow them. Two studies test the hypothesis that some women show this expected pattern of promoting women but that others show the opposite pattern, favoring men over women. In two studies, women's gender identification moderated the extent to which they favored men over women when they advanced in a male‐dominated field. Specifically, the weaker women's gender identification, the more favoritism they showed for a male relative to a female subordinate. Gender identification did not moderate women's behavior in a context in which women were not underrepresented, pointing to the power of the situation in eliciting this relationship. Implications for the advancement of women in male‐dominated fields are discussed. 相似文献
