<p>Professor George has ventured into a comparatively unchartered area seeking, as he does, to explore the art and concept of performance in Buddhism -- more specially in the context of Buddhist meditation and theatre. Spelling out the epistemology of performance in all its different connotations and definitional nuances, his study opens out an astonishingly vast panorama of the Buddhist theatrical practices in Sri Lanka, China, Japan, Nepal, Tibet . . . and goes on to demonstrate how, within this panorama, three kinds of theatrical practice can be identified, each corresponding to one of the three paths open to a Buddhist: the karma path, the Bodhisattva option, and enlightenment, and each representative of one of the three main cultures of Buddhism -- the Hinayana, Mahayana, Vajrayana. Supported by extensive endnotes and bibliographic references, Dr. George's book also carries a range of case studies of the art of performance in Buddhism, with definitive examples, among others, of the Sri Lankan Kandy dance and Karma drama, Tibetan Chams and Chod, and Japanese Noh.</p>
The conceptual system contains categorical knowledge about experience that supports the spectrum of cognitive processes. Cognitive science theories assume that categorical knowledge resides in a modular and amodal semantic memory, whereas neuroscience theories assume that categorical knowledge is grounded in the brain's modal systems for perception, action, and affect. Neuroscience has influenced theories of the conceptual system by stressing principles of neural processing in neural networks and by motivating grounded theories of cognition, which propose that simulations of experience represent knowledge. Cognitive science has influenced theories of the conceptual system by documenting conceptual phenomena and symbolic operations that must be grounded in the brain. Significant progress in understanding the conceptual system is most likely to occur if cognitive and neural approaches achieve successful integration.
Functional neuroimaging research has demonstrated that retrieving information about object-associated colors activates the left fusiform gyrus in posterior temporal cortex. Although regions near the fusiform have previously been implicated in color perception, it remains unclear whether color knowledge retrieval actually activates the color perception system. Evidence to this effect would be particularly strong if color perception cortex was activated by color knowledge retrieval triggered strictly with linguistic stimuli. To address this question, subjects performed two tasks while undergoing fMRI. First, subjects performed a property verification task using only words to assess conceptual knowledge. On each trial, subjects verified whether a named color or motor property was true of a named object (e.g., TAXI-yellow, HAIR-combed). Next, subjects performed a color perception task. A region of the left fusiform gyrus that was highly responsive during color perception also showed greater activity for retrieving color than motor property knowledge. These data provide the first evidence for a direct overlap in the neural bases of color perception and stored information about object-associated color, and they significantly add to accumulating evidence that conceptual knowledge is grounded in the brain's modality-specific systems.
How do abstract philosophies turn into lived reality? Based on 2 years of ethnographic observations and in-depth interviews of vipassana meditation practitioners in Israel and the United States, the paper follows the process through which meditators embody the three main Buddhist tenets: dissatisfaction, impermanence and not-self. While meditators consider these tenets central to Buddhist philosophy, it is only through the practice of meditation that the tenets are experienced on the bodily level and thereby are “realized” as truth. This realization takes place in the situated environment of the meditation center, where participation in long meditation retreats facilitates the production of specific subjective experiences that infuse the knowledge of Buddhist tenets with embodied meaning. The paper illustrates how abstract concepts and embodied experience support one another in the construction of meditators’ phenomenological reality and suggests a general framework for studying the variety of relations that exist between the conceptual and embodied dimensions of different types of knowledge.
Thirty years ago, grounded cognition had roots in philosophy, perception, cognitive linguistics, psycholinguistics, cognitive psychology, and cognitive neuropsychology. During the next 20 years, grounded cognition continued developing in these areas, and it also took new forms in robotics, cognitive ecology, cognitive neuroscience, and developmental psychology. In the past 10 years, research on grounded cognition has grown rapidly, especially in cognitive neuroscience, social neuroscience, cognitive psychology, social psychology, and developmental psychology. Currently, grounded cognition appears to be achieving increased acceptance throughout cognitive science, shifting from relatively minor status to increasing importance. Nevertheless, researchers wonder whether grounded mechanisms lie at the heart of the cognitive system or are peripheral to classic symbolic mechanisms. Although grounded cognition is currently dominated by demonstration experiments in the absence of well-developed theories, the area is likely to become increasingly theory driven over the next 30 years. Another likely development is the increased incorporation of grounding mechanisms into cognitive architectures and into accounts of classic cognitive phenomena. As this incorporation occurs, much functionality of these architectures and phenomena is likely to remain, along with many original mechanisms. Future theories of grounded cognition are likely to be heavily influenced by both cognitive neuroscience and social neuroscience, and also by developmental science and robotics. Aspects from the three major perspectives in cognitive science—classic symbolic architectures, statistical/dynamical systems, and grounded cognition—will probably be integrated increasingly in future theories, each capturing indispensable aspects of intelligence.
In three experiments, participants received nouns or noun phrases for objects and verbally generated their properties ("feature listing"). Several sources of evidence indicated that participants constructed perceptual simulations to generate properties for the noun phrases during conceptual combination. First, the production of object properties for noun phrases depended on occlusion, with unoccluded properties being generated more often than occluded properties. Because a perceptual variable affected conceptual combination, perceptual simulations appeared central to combining the concepts for modifiers and head nouns. Second, neutral participants produced the same distributions of properties as participants instructed to describe images, suggesting that the conceptual representations used by neutral participants were similar to the mental images used by imagery participants. Furthermore, the property distributions for neutral and imagery participants differed from those for participants instructed to produce word associations. Third, participants produced large amounts of information about background situations associated with the object cues, suggesting that the simulations used to generate properties were situated. The experiments ruled out alternative explanations that simulation effects occur only for familiar noun phrases associated with perceptual memories and that rules associated with modifiers produce occlusion effects. A process model of the property generation task grounded in simulation mechanisms is presented. The possibility of integrating the simulation account of conceptual combination with traditional accounts and well-established findings is explored.
