This study examined the Chinese name-pronunciation effect. The easy-to-pronounce and difficult-to-pronounce Chinese names were created using the same characters in order to control for visual perceptual and conceptual fluency. In Experiment 1, participants rated each name in terms of liking, electability as a state leader, income level, and baby name preference. An additional rating of prevalence was used to estimate familiarity. In Experiment 2, participants did not read the name aloud before rating and performed intentional recall and recognition tests. In both experiments, the easy-to-pronounce names were rated higher than difficult-to-pronounce names on liking. This effect generalized to judgments of electability and baby name preference but not to prevalence and income level. There were no differences in memory performances between the two types of names. Results are discussed in terms of the boundary condition of the name-pronunciation effect and the advantage of using Chinese names to study this effect. 相似文献

In the present study, the authors examined differences in brain activity, as measured by amplitudes and latencies of event related potentials (ERP) components, in Hebrew-speaking adult dyslexic and normal readers when processing sentence components with different grammatical functions. Participants were 20 dyslexic and 20 normally reading male college students aged 18–27 years. The authors examined the processing of normal word strings in word–by-word reading of sentences having subject-verb-object (SVO) syntactic structure in self- and fast-paced conditions. Data revealed that in both reading conditions, the N100 and P300 ERP components were sensitive to internal processes such as recognition of words' grammatical functions. However, the results revealed that fast-paced reading rate might affect this process, as was reflected in the systematic changes of amplitudes and latencies of both ERP components. In accelerated reading, a significant decrease of latencies and increase of amplitudes in dyslexics were shown. It was also found that influence of fast-paced reading rate was realized in the full usage of the word-order strategy in sentence processing. In turn, this fact confirmed the hypothesis concerning a syntactic processing “weakness” in dyslexia. 相似文献

The authors investigated the use of visual feedback as a form of knowledge of results (KR) for the control of rapid (200-250 ms) reaching movements in 40 participants. They compared endpoint accuracy and intraindividual variability of a full-vision group (FV) with those of no-vision groups provided with KR regarding (a) the endpoint in numerical form, (b) the endpoint in visual form, or (c) the endpoint and the trajectory in visual form (DEL). The FV group was more accurate and less variable than were the no-vision groups, and the analysis of limb trajectory variability indicated that their superior performance resulted primarily from better movement planning rather than from online visual processes. The FV group outperformed the DEL group even though both groups were obtaining the same amount of spatial visual information from every movement. That finding suggests that the effectiveness with which visual feedback is processed offline is not a simple function of the amount of visual information available, but depends on how that information is presented. 相似文献

The gain of ocular smooth pursuit responses can be adaptively modified under certain circumstances. Evidence that these modifications are caused, at least partly, by changes at a sensory level comes from the fact that subsequent manual tracking movements generated during visual fixation are also modified in a similar manner. The question addressed in the present experiment was whether the modifications are constrained specifically to responses such as these, which are driven by retinal image motion, or whether they can also influence movements that make use of retinal image position. This was accomplished by comparing manual and oculomotor responses to step changes in target position before and after smooth pursuit adaptation. The results showed that, as with manual tracking movements, these responses were also modified by the adaptive procedure, although to a lesser extent. In particular, following a 20-min period in which subjects (N = 4) were submitted to a procedure designed to increase the gain of the smooth pursuit system, manual step tracking movements and ocular saccades displayed larger amplitudes than those shown prior to the adaptation. In addition, these gain changes were accompanied by appropriate alterations in response kinematics. Taken together, these results suggest that the mechanisms responsible for adaptive modifications in the smooth pursuit system are also able to more generally influence the processing of visuospatial information. The possible neurophysiological substrate underlying these mechanisms is discussed. 相似文献

The purpose of the authors in this study is to explore the possible relationships among sensory processing styles, possible sensory processing disorders, personality traits, and body mass index. There is research on the relationship between obesity as defined by body mass index and temperament, and sensory processing and temperament; however, no information could be found on the relationship between body mass index and sensory processing styles, or the role that temperament and personality styles may play in these relationships. The 50 female participants were recruited from the University of New England community. The sample included women between the ages of 19 and 59 years, and of various weights. None of the participants had a history of thyroid problems, diabetes, or any physical disabilities that would limit daily physical activity. None had been diagnosed with sensory processing disorder. All participants filled out two self-reports and a demographic questionnaire. The Adult/Adolescent Sensory Profile (Brown &; Dunn, 2002) determines a person's sensory processing style and possible sensory processing disorder, and the Basic Personality Inventory (Jackson, 1996) focuses on everyday behaviors to describe temperament and “adult behavioral syndromes” (p. 5). Through this study the authors show only tentative relationships between body mass index and sensory processing styles and personality traits. The data could be interpreted to support both discriminant and convergent validity between the Adult/Adolescent Sensory Profile and the Basic Personality Inventory. There were, however, significant correlations between aspects of sensory processing and aspects of personality that appeared to strengthen the idea that differences in sensory processing result in predictable types of behavior, indicating that sensory processing disorders are a separate diagnostic category. 相似文献

By spanning the traditional scientific theories in the search for an epistemological home for information it is found that Physics (together with some inputs from Automata Theory) provides the criteria to identify the universals that characterize information processors. It is well known, however, that Physics and Mathematics alone are insufficient to answer some fundamental questions that arise in further speculations on the subject of information. It seems that Biology, in the realm of Evolution Theory and in terms of Natural Selection, is at present the only place able to offer the objective context required to properly characterize information as an object of scientific inquiry. In this communication we intend to show, by establishing a working equivalence between the epistemological questions that should characterize a theory of information and those questions that characterize the science of Biology, how a science of information can be more objectively characterized. It is only by referring to selective pressures that we can solve the otherwise unanswerable philosophical question of whether it is possible to know if two players of a game are, in fact, playing the same game (the semantic question). It is also shown that it is possible, by using conventional criteria, to establish a phylogenesis of information processors from where we conclude that every information processor now existing in the universe (even computers and robots) has an ancestor that has once been a living being. It is here suggested, however, that Biology is only a provisory epistemological ground for laying the foundations of an information science. A more inclusive theory should be founded on a generalization of the Theory of Evolution where mutation and natural selection should be described, not in terms of the characteristic media and mechanisms of biological systems, but of the identified universals of information processors. 相似文献

Many indicators suggest that modern society is presently in a period of transition. The older order is showing obvious signs of decline, and elements of a new order appear to be forming. Growing numbers of people are coming to recognize that the worsening global dilemmas are best viewed as symptoms of an underlying disorder involving some of the most deeply underlying assumptions of modern society. The ultimate resolution of these dilemmas will come about, not through politically implemented “solutions,” but through our further evolution to a fundamentally different, “trans‐modern” society. The key challenge to individuals and organizations is to understand the necessary evolutionary change well enough to contribute toward its taking place with a minimum of attendant social disruption and human misery. 相似文献

This article pulls together the disjointed complexification of security studies. Such analytical overview suggests that the perspective of “timescapes” allows for exploring the complexity that shapes meanings and practices of security and its governance. In this respect, it is the imperative to change that suggests the significance of complexity thinking to security studies—that is, it is alone in taking the discontinuities of global life seriously. Security, in this regard, is not merely about the clockwork of survival, but is redefined through the cloudlike adaptive contingency of “security as resilience.” In this setting, the security governance of complexity is identified through its dancing to the timescaped rhythms of uncertainty, cognitive challenges, complex risks, and exaptation prompted by the heterogeneity of global life. 相似文献

Little research has investigated functional relations among attention, interpretation, and memory biases in depressed samples. The present study tested the indirect effect of attention bias on memory through interpretation bias as an intervening variable in a mixed sample of non-depressed and subclinically depressed individuals. Subclinically depressed and non-depressed individuals completed a spatial cueing task (to measure attention bias), followed by a scrambled sentences test (to measure interpretation bias), and an incidental free recall task (to measure memory bias). Bias-corrected bootstrapping yielded evidence for the hypothesised indirect effect model, in that an emotional bias in attention is related to a congruent bias in interpretative choices which are in turn reflected in memory. These findings extend previous research and provide further support for the combined cognitive bias hypothesis in depression. Theoretical and clinical implications of our findings are discussed. 相似文献

Attentional interference by threat is associated with PTSD, but the mechanisms of this relationship remain unclear. Attentional interference might be related to increased use of maladaptive thought control strategies, such as suppressing unwanted thoughts (thought suppression) or replacing threatening thoughts with everyday concerns (worry), which increase PTSD risk. Conversely, attentional interference might be associated with reduced use of adaptive strategies, such as talking about threatening thoughts (social control), which decrease PTSD risk. This study tested if thought control strategies mediate the relationship between attentional interference and PTSD. Sixty-one male Vietnam-era veterans completed measures of PTSD symptoms and thought control strategies. Participants also completed a Visual Search Task measuring attentional interference, which required participants to identify a target letter string among a group of threat or neutral words. Attentional interference by threat was related to PTSD symptoms, and mediation analyses revealed significant indirect effects of attentional interference through thought suppression and worry. Attentional interference was related to re-experiencing and avoidance, but not hyperarousal, symptom clusters. Thought suppression was a unique mediator for re-experiencing, whereas thought suppression and worry both mediated the relationship with avoidance. These results offer evidence for maladaptive thought control strategies as a mechanism linking attentional biases for threat to PTSD. 相似文献
