This article addresses the issue of animation as an aid for temporal processing difficulties in deaf people learning the Highway Code. A decision-making task involving static or animated road situations was performed by 21 deaf and 24 hearing participants. They were confronted with four types of driving situations (overtaking, negotiating roundabouts, highways, and intersections) and had to decide whether or not to proceed. Participants were presented with two different formats (static vs. animated) and two levels of difficulty (simple vs. complex). Results showed that deaf participants had poorer performances in the static condition than hearing participants. Performance was better in the animated condition than in the static condition, especially in deaf participants. The benefits of animation were greater in complex situations for all participants. Decisions made on dynamic road situations were facilitated by the presence of spatiotemporal dimensions. These proved helpful to deaf candidates who have difficulties in this particular area. 相似文献

Contextual guidance of eye movements and attention in real-world scenes: the role of global features in object search 总被引:2,自引:0,他引:2
Many experiments have shown that the human visual system makes extensive use of contextual information for facilitating object search in natural scenes. However, the question of how to formally model contextual influences is still open. On the basis of a Bayesian framework, the authors present an original approach of attentional guidance by global scene context. The model comprises 2 parallel pathways; one pathway computes local features (saliency) and the other computes global (scene-centered) features. The contextual guidance model of attention combines bottom-up saliency, scene context, and top-down mechanisms at an early stage of visual processing and predicts the image regions likely to be fixated by human observers performing natural search tasks in real-world scenes. 相似文献

The statistical analysis of data from small groups 总被引:1,自引:0,他引:1
Kenny DA Mannetti L Pierro A Livi S Kashy DA 《Journal of personality and social psychology》2002,83(1):126-137
The authors elaborate the complications and the opportunities inherent in the statistical analysis of small-group data. They begin by discussing nonindependence of group members' scores and then consider standard methods for the analysis of small-group data and determine that these methods do not take into account this nonindependence. A new method is proposed that uses multilevel modeling and allows for negative nonindependence and mutual influence. Finally, the complications of interactions, different group sizes, and differential effects are considered. The authors strongly urge that the analysis model of data from small-group studies should mirror the psychological processes that generate those data. 相似文献

In predictive causal inference, people reason from causes to effects, whereas in diagnostic inference, they reason from effects to causes. Independently of the causal structure of the events, the temporal structure of the information provided to a reasoner may vary (e.g., multiple events followed by a single event vs. a single event followed by multiple events). The authors report 5 experiments in which causal structure and temporal information were varied independently. Inferences were influenced by temporal structure but not by causal structure. The results are relevant to the evaluation of 2 current accounts of causal induction, the Rescorla-Wagner (R. A. Rescorla & A. R. Wagner, 1972) and causal model theories (M. R. Waldmann & K. J. Holyoak, 1992). 相似文献

We discuss Kunen’s algorithmic implementation of a proof for the Paris–Harrington theorem, and the author’s and da Costa’s
proposed “exotic” formulation for the P = NP hypothesis. Out of those two examples we ponder the relation between mathematics within an axiomatic framework, and intuitive
or informal mathematics.

This study examines perceptions of the "typical American" from 49 cultures around the world. Contrary to the ethnocentric bias hypothesis, we found strong agreement between in-group and out-group ratings on the American profile (assertive, open-minded, but antagonistic); Americans in fact had a somewhat less desirable view of Americans than did others. Within cultures, in-group ratings were not systematically more favorable than out-group ratings. The Iraq invasion had a slight negative effect on perceptions of the typical American, but people around the world seem to draw a clear distinction between U.S. foreign policy and the character of the American people. National character stereotypes appear to have a variety of sources and to be perpetuated by both cognitive mechanisms and socio-cultural forces. 相似文献

Using the paradigm, participants were engaged in a fictitious face recognition experiment in which three between-subject conditions were manipulated by either adding or not adding wrinkles on the faces between the study and the recognition tasks (no change, single change, double change). Our hypothesis was that this procedure would maximize judgments based on familiarity, thus determining whether data provided better fit to the models based on the signal detection theory or to predictions of dual models. In global terms, our results support the signal detection model predictions, although we discuss whether these models better fit tasks based on familiarity or tasks based on recollection. 相似文献

Is it possible to learn to attend? The purpose of this article is to provide information about the development, administration, and contrast of an intervention program to improve selective and sustained attention in students from 5 to 19 years of age, all attending school, and with difficulties to learn the academic materials corresponding to their age. Two groups participated in the study: one with difficulties in selective attention and the other with difficulties in sustained attention. The group with selective attention difficulties was made up of 102 students, of whom 59 made up the experimental group and 43 the control group. The group of students with difficulties in sustained attention was made up of 106 students, of whom 58 participated as the experimental group and 48 as the control group. The results indicate that this kind of intervention (which combines visual therapy, cortical activation, and training with activity banks) is effective to improve attentional deficits, both at the level of selective attention and of sustained attention. 相似文献

When analyzing genetic data, Structural Equations Modeling (SEM) provides a straightforward methodology to decompose phenotypic variance using a model-based approach. Furthermore, several models can be easily implemented, tested, and compared using SEM, allowing the researcher to obtain valuable information about the sources of variability. This methodology is briefly described and applied to re-analyze a Spanish set of IQ data using the biometric ACE model. In summary, we report heritability estimates that are consistent with those of previous studies and support substantial genetic contribution to phenotypic IQ; around 40% of the variance can be attributable to it. With regard to the environmental contribution, shared environment accounts for 50% of the variance, and non-shared environment accounts for the remaining 10%. These results are discussed in the text. 相似文献

The present study aimed to explore sexist attitudes in young people and to investigate the role of these ideologies in the
contribution of boys and girls to housework. For this purpose, 139 Spanish high school students (67 females and 72 males)
responded to the ASI and AMI scales (Glick and Fiske in Journal of Personality and Social Psychology 70:491–512, 1996, Psychology
of Women Quarterly 23:519–536, 1999) and assessed their contribution to housework in tasks considered traditionally done by
women (highly gender-typed) or more neutral tasks (sex-neutral). Results showed that girls contributed significantly more
to housework than boys. In addition, correlation analyses showed that benevolent sexism toward women, men and hostility toward
men were significant related to highly gender typed tasks only in the female sample. This result shows the relevance of sexist
ideologies in maintaining established differences between genders. 相似文献
