Mental rotation, as a covert simulation of motor rotation, could benefit from spatial updating of object representations. We are interested in what kind of visual cue could trigger spatial updating. Three experiments were conducted to examine the effect of dynamic and static orientation cues on mental rotation, using a sequential matching task with three-dimensional novel objects presented in different views. Experiment 1 showed that a rotating orientation cue with constant speed reduced viewpoint costs in mental rotation. Experiment 2 extended this effect with a varied-speed rotating orientation cue. However, no such benefit was observed with a static orientation cue in Experiment 3. These findings indicated that a visually continuous orientation cue is sufficient to elicit spatial updating in mental rotation. Furthermore, there may be differences in the underlying mechanisms of spatial updating on the basis of constant-speed rotating cues and varied-speed rotating cues. 相似文献

Researchers propose social support as one of the factors that may explain the positive relationship often observed between religious involvement and health outcomes. African-Americans are a population that tends to have higher than average levels of religious involvement and are also disproportionately impacted by most health conditions. The present study sought to determine whether social support mediates the role of religious involvement in physical and emotional functioning and depressive symptoms, among a national probability sample of African-Americans (N = 803). Study participants completed telephone interviews. We used structural equation modelling to test hypotheses based on the theoretical model. Findings suggest evidence for a mediating role of belonging and tangible support in the association between religious behaviours and physical functioning as well as depression. There was no mediational role played by appraisal support, or for emotional functioning. Implications for faith-based health promotion interventions are discussed. 相似文献

This article introduces a new affordance framework for humans and human design. Based on previous important concepts in product design–affordance, signifier, and product semantics, the authors propose three new concepts to illustrate how people perceive affordance. According to the model, perceptual probability of affordance is the probability that the public can perceive a certain affordance; perceptual threshold of affordance is the threshold at which affordance can be perceived by a person and changed by perceptual information; and situations, in which interactions between affordances and people exist, are crucial influences on human–affordance interactions. An illustration of the model and suggestions for further research are provided. 相似文献

汉语语句重音的分类和分布 总被引:9,自引:0,他引:9
通过两个独立进行的重音标注实验对汉语语句重音的分类和分布进行了初步探讨。实验l是由60位普通被试参加的音节重音突显度的知觉实验。实验2是由本文三位作者参加的重音类别标注实验,在此实验中语句重音被划分为节奏重音和语义重音。实验2中对于语句重音的分类性标注结果得到了实验l中普通被试对音节重音突显度知觉结果的支持,这说明人们确实能够感知到两种不同类型的重音。实验结果还表明,节奏重音倾向于出现在较大韵律单元内的最末韵律词的末音节上,并且与适当的停延相伴生,语义重音的分布则与语句的韵律结构的关系不大。 相似文献

被遮蔽的"流动"之魂——辩证发展模式自身的辩证法透视 总被引:1,自引:0,他引:1
对辩证发展过程的理解总是与"三段式"联系在一起.然而"三段式"作为黑格尔对古希腊辩证法的发掘和改造,并没有达到表现论的成熟境界,其本身还需要进一步发掘.如果剥去"三段式"的日常语言外衣使其形式化,那么,"正反合"的过程就表现为一个以环节为其结构成分的周期链.以辩证否定的眼光来解读这个周期链,可以发现其中蕴涵了无数种变易的可能性,"三段式"只是其中的典型表达式而不是唯一的表达式.于是,辩证发展的模式就由"一个关系式"的阶段进入到"关系式的变易体系"阶段,从而具有了强大的解释功能. 相似文献

Emotional inferences from speech require the integration of verbal and vocal emotional expressions. We asked whether this integration is comparable when listeners are exposed to their native language and when they listen to a language learned later in life. To this end, we presented native and non-native listeners with positive, neutral and negative words that were spoken with a happy, neutral or sad tone of voice. In two separate tasks, participants judged word valence and ignored tone of voice or judged emotional tone of voice and ignored word valence. While native listeners outperformed non-native listeners in the word valence task, performance was comparable in the voice task. More importantly, both native and non-native listeners responded faster and more accurately when verbal and vocal emotional expressions were congruent as compared to when they were incongruent. Given that the size of the latter effect did not differ as a function of language proficiency, one can conclude that the integration of verbal and vocal emotional expressions occurs as readily in one's second language as it does in one's native language. 相似文献
