To gain a better understanding of the functionality of representation and categorization in action and interaction, it is fundamental that researchers understand how movements are represented in long-term memory. It is our position that human motor control requires that our actions be planned and represented in terms of intended perceptual effects and future task demands, and that the individual has a well-structured mental representation of the task so that the movement can be carried out successfully. Basic Action Concepts (BACs) are identified as major building blocks of cognitive representation in long-term memory, which are cognitive tools used to master the functional demands of movement tasks. In this paper, we consider relevant issues in research methodology and present an experimental method that can be used to assess action-relevant representational structures. This method permits us to observe the strong relationship between cognitive representation and performance in manual action. For example, the specific differences in the mental representations of participants are strongly related to skill level, as well as biomechanical and task constraints. We then discuss results from our learning experiments, where we have examined the development and changes in cognitive representation over time. From these experiments we have found that cognitive reference structures include task-specific spatial information, which provides the basis for action control in skilled voluntary movement. We have implemented these results on various robotic platforms. We argue that the insights gained from various experimental approaches in the field of cognitive psychology and motor control enable researchers to explore the possibilities and limitations of artificial control architectures in robot systems. Finally, we argue that this is not a unidirectional process. Researchers from the field of cognitive psychology and motor control can profit from the advances in technological systems, which enhance the understanding of human motor control in skilled voluntary action.  相似文献

This study addresses the causes and potential mediators of social loafing on tasks which require active cognitive effort. Contrary to previous research, social loafing did occur despite the use of a task which was thought-provoking, personally involving, and provided the opportunity for unique contributions. The results suggest that equity theory, which has been supported as a reason for social loafing on physical tasks, may also be the basis for loafing on cognitive tasks. No significant loafing occurred when the subjects believed their partners would not loaf.  相似文献

ObjectiveThe aim of this study is to investigate the effects of family centered physiotherapy according to the neurodevelopmental treatment (NDT) principles on mental and motor performance in premature infants.MethodsA total of 156 infant, ≥24/36 week + 6 days gestational age included in the study. All the infants were diagnosed by a child neurologist and referred to psychology and physiotherapy department for their neurodevelopmental assessment and treatment. Bayley Scale of Infant II (BSI-II) was used for neurodevelopmental assessment and Alberta Infant Motor Scale (AIMS) was used for assessing their motor performance. Seventy-eight of the infants were in the study group and 76 were recruited as age matched controls according to the classification of their gestational age. Family centered physiotherapy according to the neurodevelopmental treatment principles was used as an intervention and all the mothers are trained accordingly.ResultsCognitive Development Scores and Motor Development Scores of Bayley II were recorded for the 3., 6., 9., and 12 months respectively. Between the 3. and 12. month of gestational age, within-groups measurements in both Cognitive Development Scores (p < 0.001) and Motor Development Scores (p<0.001) were significantly increased. However, the improvements in both Cognitive Development Scores (p = 0.059) and Motor Development Scores (p = 0.334) between the groups was not different.ConclusionFamily centered physiotherapy with NDT principles may not be enough to improve motor and cognitive performance in preterm infants at the first year of age. For supporting the motor and cognitive development of the preterm infants other intervention modalities also should be considered. Keywords: infants; premature; early intervention  相似文献

Throughout pregnancy and into the immediate postpartum period, women are generally perceived to be incompetent, stressed, and forgetful. However, the neuropsychological “baby brain” literature remains unclear and contradictory. Across two studies, we provide the first experimental tests of whether perceived cognitive impairment in pregnancy can be explained by stereotype threat theory, which proposes that awareness of negative stereotypes about one’s ingroup can harm performance. In Study 1 (N = 364), we tested stereotype threat effects in a 2 (stereotype threat versus no threat) × 3 (pregnant women versus new mothers versus never-pregnant female control) design. We observed a main effect of group on memory performance (pregnant women and new mothers performed worse than controls), but no other main or interactive effects. Study 2 (N = 409) aimed to extend these research questions with mathematics ability, memory, and attention as the dependent variables. Again, we found that a stereotype threat manipulation did not impair pregnant women and new mothers’ cognitive performance, nor was there any interactive effects. Groups also did not differ in their performance. We discuss these results in the context of stereotype threat mechanisms, calling into question whether a stereotype threat paradigm can be applied effectively to pregnancy-related stereotypes. This work has implications for the advancement of stereotype threat as a theory and contributes to the reappraisal of the utility of stereotype threat as a way of understanding how stereotypes affect performance.  相似文献

A persistent criticism of radical embodied cognitive science is that it will be impossible to explain “real cognition” without invoking mental representations. This paper provides an account of explicit, real-time thinking of the kind we engage in when we imagine counter-factual situations, remember the past, and plan for the future. We first present a very general non-representational account of explicit thinking, based on pragmatist philosophy of science. We then present a more detailed instantiation of this general account drawing on nonlinear dynamics and ecological psychology.
