Cognitive and motor coordination skills of children with and without motor coordination impairments were examined with a one-year follow-up investigation. Initially, children were between 4 and 6 years old. Age-appropriate tests of executive functions (updating, switching, inhibition, interference control), motor coordination (the Movement Assessment Battery for Children-2) and fitness (the Körperkoordinations-Test für Kinder) were administered in two consecutive years. Several background variables (age, socioeconomic status, medical support, clinical interventions, leisure activities) and potential moderators (nonverbal intelligence, reaction time, visual perception) were controlled. The matched sample consisted of 48 control children and 48 children with motor coordination impairments. The children’s executive functions dramatically improved during the one-year period. With regard to motor coordination performance, half of the impaired children caught up to the control children’s level (“remission group”), while the remaining half showed no improvement (“persisting group”). Compared to the persisting group, the children in the remission group showed markedly better interference control at both measurement points. The correlation between executive functions and motor coordination is significant in the persisting group, but not in the remission group. The results of the study are discussed in the light of the role of executive functions, especially inhibition processes, for the automatization of motor coordination tasks.  相似文献

Interpersonal motor coordination is influenced not only by biomechanical factors such as coordination pattern, oscillating frequency, and individual differences, but also by psychosocial factor such as likability and social competences. Based on the social stereotype of “what is beautiful is good”, the present study aimed at investigating whether people coordinate differently with physically attractive people compared to less attractive people. 34 participants were engaged in an interpersonal coordination task with different looking (virtual) agents while performing at the same time a reaction time task. Results showed that participants had more stable motor coordination with the moving attractive than with the less attractive agent, and that the difference in motor coordination could not be interpreted by a specific attention allocation strategy. Our findings provide the evidence that physical attractiveness genuinely affects how people interact with another person, and that the temporal-spatial coordinated movement varies with the partner’s psychosocial characteristics. The study broadens the perspective of exploring the effect of additional psychosocial factors on social motor coordination.  相似文献

Building on previous work, I continue the arguments for scientific realism in the presence of a natural level structure of science. That structure results from a cognitive antireductionism that calls for the retention of mature theories even though they have been “superseded”. The level structure is based on “scientific truth” characterized by a theory's validity domain and the confirming empirical data. Reductionism (including fundamentalism) fails cognitively because of qualitative differences in the ontology and semantics of successive theories. This cognitive failure exists in spite of the mathematical success of theory reduction. The claim for scientific realism is strongly based on theory coherence between theories on adjacent levels. Level coherence consists of mathematical relations between levels, as well as of reductive explanations. The latter refers to questions that can be posed (but not answered) on a superseded level, but which can be answered (explained) on the superseding level. In view of the pluralism generated by cognitive antireductionism, theory coherence is claimed to be so compelling that it provides strong epistemic justification for a pluralistic scientific realism.  相似文献

Explanation of how goal-directed movements are made manifest is the ultimate aim of the field classically referred to as “motor control”. Essential to the sought-after explanation is comprehension of the supporting functional architecture. Seven decades ago, the Russian physiologist and movement scientist Nikolai A. Bernstein proposed a hierarchical model to explain the construction of movements. In his model, the levels of the hierarchy share a common language (i.e., they are commensurate) and perform complementing functions to bring about dexterous movements. The science of the control and coordination of movement in the phylum Craniata has made considerable progress in the intervening seven decades. The contemporary body of knowledge about each of Bernstein’s hypothesized functional levels is both more detailed and more sophisticated. A natural consequence of this progress, however, is the relatively independent theoretical development of a given level from the other levels. In this essay, we revisit each level of Bernstein’s hierarchy from the joint perspectives of (a) the ecological approach to perception-action and (b) dynamical systems theory. We review a substantial and relevant body of literature produced in different areas of study that are accommodated by this ecological-dynamical version of Bernstein’s levels. Implications for the control and coordination of movement and the challenges to producing a unified theory are discussed.  相似文献

人格智力(PI)是指个体在对人格及其相关信息推理的基础上,利用这些信息提高一个人的思想、计划和生活经验的能力,包括识别人格信息、形成人格模型、引导个人选择以及系统化计划和目标等相关领域。作为一种新兴的“热智力”,PI并没有像当年情绪智力(EI)那样受人关注。文章从PI的范畴、领域及其局限性等角度分析了这一新能力遭遇“冷落”的原因,指出了PI在整合以人为中心的智力过程中存在概念宽泛、界限模糊、测量的科学性及其形成与发展等诸多值得反思的问题。  相似文献

The paper notes (1) that “thinking Gibsonian” is to be torn between two loves: cognition and reality, (2) that just because of this the cognitive scientist may beneficiently and more thoroughly rediscover that they are only two faces of his one true love: Meaning. This issue is elaborated as “the problem of intentionality” and culminates in the conclusion that Gibson's direct ecological approach to visual perception is not a theory about the constitution of perceptual meaning, which is the domain of the indirect cognitive approach. Therefore the constant Gibsonian attacks on indirect theories might be both misled and misleading. The second half of the paper begins with noting that this may be due to a confounding of the “direct” level of explanation of the perceiver with the “indirect” levels of phenomenologist and visual scientist. Next the scientist's process notions of direct and indirect theories are discussed with respect to single-glance face recognition. Within this second half of the paper about 20 different meanings of “direct” or “immediate” are presented (printed in italics). Most of these are generally acceptable and should, thus, not be invoked in support of entirely different notions, which are very problematic because these seem to eliminate the concept of mind-as-cognitive-process.  相似文献

Appropriate play with toys was studied in two autistic children with high occurrences of self-stimulatory behavior. Each child participated in the experimental sessions in an A-B-A design, where “A” refers to baseline sessions and “B” refers to self-stimulation suppression sessions. It was found that: (a) during the baseline sessions, the children exhibited low levels of play and high levels of self-stimulatory behavior; (b) the per cent of unreinforced, spontaneous, appropriate play increased when self-stimulatory behavior was suppressed; and (c) when the suppression of self-stimulation was discontinued, the per cent of self-stimulation and that of appropriate play approached their presuppression levels. These results seem particularly significant because they identify a set of conditions under which spontaneous appropriate behavior, uncommon in autistic children, occurs at an increased level.  相似文献

In everyday life, situations in which we act adequately yet entirely without deliberation are ubiquitous. We use the term “situated normativity” for the normative aspect of embodied cognition in skillful action. Wittgenstein’s notion of “directed discontent” refers to a context-sensitive reaction of appreciation in skillful action. Extending this notion from the domain of expertise to that of adequate everyday action, we examine phenomenologically the question of what happens when skilled individuals act correctly with instinctive ease. This question invites exploratory contributions from a variety of perspectives complementary to the philosophical/ phenomenological one, including cognitive neuroscience, neurodynamics and psychology. Along such lines we try to make the normative aspect of adequate immediate action better accessible to empirical research. After introducing the idea that “valence” is a forerunner of directed discontent, we propose to make progress on this by first pursuing a more restricted exploratory question, namely, ‘what happens in the first few hundred milliseconds of the development of directed discontent?’  相似文献

Perversion has been traditionally the “domain of men”. The necessity and ability inherent in perversion of sexualizing aggression, of externalization and fetish formation were regarded as specific characteristics of male development. Perversions of women were not recognized, because they were looked for in the wrong place, without taking into account the significance of the particular female body experience for the psychosexual development of the woman. In the perversion of the woman the externalization and fetish formation refers to the whole of the own body and especially to the uterus and the child (as an own “product” or as a part of the own body). The female perversions are presented and interpreted here on the basis of case studies.  相似文献

维度比较是指个体将自身某一目标领域的能力与自身标准领域的能力相比较的过程,它是继社会比较和时间比较之后又一重要比较方式。当比较领域性质差异较大,即当比较领域之间进行"远比较"时,会发生强烈的对比效应。随着比较领域性质差异逐渐缩小,即当比较领域之间进行"近比较"时,对比效应会逐步减小,甚至会发生同化效应。维度比较和社会比较都对自我概念具有显著影响,但社会比较的作用明显大于维度比较。未来研究应考虑进一步扩展维度比较的应用范围、加强和其它比较方式的整合、改善其研究方法。  相似文献

Need and meaning of comparative studies in genetic psychology. — The comparative studies in the field of genetic psychology are indispensable for Psychology in general and also for Sociology, because only such studies allow us to separate the effects of biological or mental factors from those of social and cultural influences on the formation and the socialization of individuals. Relevant to this discussion is the well-known issue between culturalistic psychoanalysts like Fromm, Horney, etc., and classical freudian psychoanalysts who reduce the whole individual development to an endogenous evolution of « instinct ». In the field of cognitive functions to which this paper is devoted, at least four kinds of various factors must be distinguished, the respective influences of which can be separated through comparative studies : I. Biological factors depending on the “epigenetic” system (maturation of nervous system, etc.). These factors probably explain the sequential aspects (constant and necessary order) of the stages in the development of operative intelligence. However, if only these factors were acting, the stages would not only appear in a sequence, but at the same ages, whereas in fact, the ages where a stage appears differ from one environment to another. 2. Equilibration or autoregulation factors, determining behavior and thought in their various specific activities. They correspond to the sequential forms in general coordination of the actions of individuals as interacting with their physical environment; such intervening regulations are probably at the origin of the mental operations themselves, especially logical - mathematical operations. 3. General socialization factors, which are identical for all societies : cooperations - discussions - oppositions - exchanges, etc., between children or between adults or between adults and children. These factors 3 are closely related with the factors 2, because the general coordination of actions concerns inter-individual as so as intra-individual actions. 4. Factors related to educational and cultural transmission, which differ from one society to another; they are those we usually have in mind when we say briefly “social factors”. To discuss the influence of these four factors, Mohseni's study on Teheran school children and illiterate rural children is given as an example. Three results were obtained : (1) For “conservation” tasks, the same stages of intellectual development are observed for urban and rural children, in Iran as well as in Europe. (2) For these same tasks, a systematic delay of two to three years is observed among rural children with respect to Teheran children. (3) For performance tests (i.e. Porteus, Goodenough, etc.) there is a delay of four and primarily five years. These data seem to show that there is some sequential order of the stages which depends partially on the factors I. But, the ages for each stage are not constant, showing the factors 2 and 3 are intervening in a probably inseparable way. On the other hand, the difference between the actual operative results and the performance tests seems to indicate that a distinction might be made between the factors of general coordination (factors 2 and 3) and the educational transmissions (factors 4). About these last factors, the three and four year delays observed by Canadian psychologists working in Martinique with school children (French curriculum) in operative tasks (like conservations) seem to indicate that the general operations depend less on school than on the activities themselves of children or in general on the adult stimulations in the environment. We must pay special attention to the problems raised by language. In some precise and systematic experiments in Geneva, Sinclair shows children on the “preoperative” level (i.e. with no conservation…) do not spontaneously use the same language as operative children : the former use chiefly “scale” words (“much” or “many”, “little” or “few”, “large”, “small”) and the latter use chiefly “vector” words (“more”, “less”). If the younger subjects are submitted to a verbal training, they do learn to use the older children's language, but it only results in very little operative improvement (about one case out of 10 subjects on the average). Therefore, replicating the same experiments in countries speaking different languages would be very interesting. For instance, in the Turkish language, there is only one “vector” word, i.e. “again”; so that the Turk says “again much, again many” to say “more”. Then, the question is to know whether a change will be observed for the stages of logical-mathematical operations or whether these operations will be found everywhere with their identical common background; it seems that this last conclusion has already been observed in Aden (Hyde), Hong Kong (Goodnow), South Africa (Price-Williams). In conclusion, the kind of psychology we develop in our social environments, remains conjectural as long as comparative extensive and systematical research is not available; a great effort is still to be made in this direction.  相似文献

For nearly four decades bimanual coordination, “a prototype of complex motor skills” and apparent “window into the design of the brain,” has been intensively studied. Past research has focused on describing and modeling the constraints that allow the production of some coordination patterns while limiting effective performance of other bimanual coordination patterns. More recently researchers have identified a coalition of perception-action constraints that hinder the effective production of bimanual skills. The result has been that given specially designed contexts where one or more of these constraints are minimized, bimanual skills once thought difficult, if not impossible, to effectively produce without very extensive practice can be executed effectively with little or no practice. The challenge is to understand how these contextual constraints interact to allow or inhibit the production of complex bimanual coordination skills. In addition, the factors affecting the stability of bimanual coordination tasks needs to be re-conceptualized in terms of perception-related constraints arising from the environmental context in which performance is conducted and action constraints resident in the neuromotor system.  相似文献

The early organizing process of the American railroads could be periodized as follows: Railroad technology become perfected by the 1860s, the national network become perfected by the 1880s, and self‐sustaining railroad systems by the 1900s. The evolutionary path seems to be largely dictated by the “perfection” of stable configurations of “lower levels,” such as technological standards (e.g., uniform standard time). In the American railroads, on each level of activity there was a process of convergence, learning and coordination of pre‐existing components toward “equilibrium,” that allowed the emergence of new combinations, i.e. new levels of integration. Thus, convergent level‐specific process, i.e. the standardization and formalization of existing activities, was an essential step for radical process of divergence in the American railroads.  相似文献

How do memory retrieval processes lead to overt responses in strategic recognition tasks (responding “old” to one class of familiar stimulus and “new” to another)? Many current theories of memory retrieval ignore the response requirements in such memory tasks, instead modeling them using memory processes (e.g., familiarity and recollection) alone (see Yonelinas, 2002). We argue that strategic recognition involves conflict in response processing similar to canonical conflict tasks (e.g., the Stroop task). The parallel task set (PTS) model (Seymour, 2001) accounts for performance in strategic recognition tasks (e.g., the exclude recognition task) by suggesting that motor response conflict occurs when one responds “new” to familiar stimuli. We tested this prediction using surface electromyography, a measure incontrovertibly related to motor execution. Overall, results are consistent with the PTS model’s assumption that recognition, motor, and control processes interact in strategic retrieval tasks. The implications of these data for models of memory retrieval and response conflict are discussed.  相似文献

Pioneer experiments on saccadic suppression have shown that this effect is not followed by motor disorientation: Conscious perception of a target displacement can be dissociated from correct manual target reaching. It has subsequently been demonstrated that movement corrections with the same latency and spatial characteristics can be produced in conditions allowing perceptual awareness of perturbation of a target as in condition inducing saccadic suppression. In addition to the qualitative dissociation between motor performance and conscious awareness, quantitative temporal dissociations in action can be observed by manipulating different features of the visual target. When the target of an ongoing simple action is perturbed, a temporal advantage is found for responses to perturbations of location relative to colour and shape. Furthermore, there seems to be a temporal advantage for automatic motor corrections made in response to a target displacement as compared to other responses (other ongoing movement adjustments, movement interruption, conditional motor response such as pressing a key, verbal response, delayed matching-to-sample tasks). Thus, this paper reviews evidence for the fact that the temporal characteristics of any given response to a stimulus are dependent both on the sensory processes and on the type of response generated. Accordingly, identification responses (such as verbal report) to a visual stimulus are much slower than motor corrections of an ongoing movement in response to a target location change because of different processing times of the stimulus features (“What” compared to “Where”) and of the response itself (“What” compared to “How”). The existence of two continua (What/Where and What/How) is proposed between these two extreme stimulus- response combinations. This model may be a useful framework to better understand visuo-motor transformations and the network of connections between visual and motor areas.  相似文献

概念如何被表征是认知科学的热点问题,其中抽象概念如何表征是当前具身认知最具争议性的话题之一。与前期概念隐喻理论(强调意象图式)和知觉符号理论(强调情境内省信息)的观点不同,语义表征具身理论强调情绪经验信息在抽象概念表征和加工中的作用。具体而言,具体概念的表征主要来自感觉运动信息,而抽象概念的表征主要来自情绪经验信息和语言信息。研究证明,抽象概念的高情绪经验信息能够促进词汇的加工,且这一促进作用受词汇情绪效价的调节。未来研究应进一步考虑影响情绪经验信息发挥作用的因素,比如语言信息的丰富性、情绪唤醒或个体的情绪状态等。  相似文献

已有研究显示物体的成因等变量会影响人造物概念的分类;但这种影响的中介变量为何,基于设计和基于用途的理论有不同的假设。实验采用物体自由命名任务,在陈述物体的功能时,操纵角色词的类型(旁观者“有人”和使用者“你”),比较被试对物体的命名在领域水平的分类倾向。结果发现,呈现“旁观者”角色词时,呈现或不呈现物体自然形成的成因故事会造成不同的分类倾向;但是在呈现“使用者”角色词时,成因故事对分类倾向的影响消失了。提示物体的功能是成因和分类的中介变量,支持基于用途的人造物分类模型  相似文献

Two cases are presented to illustrate how psychological knowledge and technology have been used in Venezuela. The first case relates to the use of psychological technology in Venezuelan politics where it is possible to identify a change from “caudillismo” to a more democratic “voting against” political culture. There is evidence that imported political compaigning techniques and extensive use of polling have been a factor of some importance in such change. The second case refers to the activities of the Minister for the Development of Intelligence, who has started a group of projects to improve cognitive functioning in different age groups. These programs are too recent to ascertain their effectiveness; so data is reported on an opinionative evaluation of one of the projects, carried out among Venezuelan psychologists and pediatricians.  相似文献

Contemporary Chinese ethics faces two theoretical tasks: expansion in breadth and exploration in depth. The former refers to the opening of the problem area, and the latter refers to the deepening of ethics itself. To get out of the dilemma that academic results in the area are abundant in quantity but low in quality, contemporary Chinese ethics should expand and deepen in the three dimensions, namely, “no longer,” “being” and “not yet.” Within the framework of “no longer,” efforts should be made to deepen the studies of the history of moral concept and practice, and the ethics of culture from the perspective of genetics; with regard to the perspective of “being,” the ethical reflection on public crisis, system and Lnstitutional ethics, the dilemma of virtue theory and normative theory, and the conflicts and generalization between different moral paradigms will become the difficulties that require in-depth analysis and demonstration. As for the contemporary Chinese ethics towards “not yet,” attention must be paid to the duality of modern technology, the origin of human ethics based on building a community with a shared future for mankind and the moral philosophy that goes deep into people’s minds. To complete the above theoretical tasks, one must have judgment, thinking, and willingness, which can only be cultivated in the experience and thinking of “practical” life.  相似文献

Abstract: This article addresses recent claims made by Richard Rorty about antirepresentationalist theories of meaning. Rorty asserts that a faithful rendering of the core antirepresentationalist assumptions precludes even revised pieces of representationalist semantics like “refers” or “true” and epistemological correlates like “answering to the facts.” Rorty even asserts that such notions invite reactionary authoritarian elements that would impede the development of a democratic humanism. I reject this claim and assert that such notions (suitably constructed) pose no greater threat to democratic humanism than the alternatives and in fact are crucial to its maintenance and continuing success. These notions (suitably constructed) reflect a metatheoretical stance that I call “openness,” which I believe lies at the heart of both democratic humanism and the pragmatism from which Rorty claims to take his inspiration.  相似文献
