Generalizing everyday memory: Signs and handedness

Memory for frequently encountered road signs was investigated. In Experiment 1, the average level of recall of road sign features was found to be only 47%. In Experiment 2, more left-handed than righthanded people recalled that a walking figure faces right on one sign, whereas more right-handed than left-handed people recalled that a digging figure faces left on another sign. Performance thus reflected not a difference in level of mnemonic ability between left-handed and right-handed groups but instead the compatibility between group and task. In Experiment 3, participants were asked to draw any figure walking and any figure digging, with a pattern of results similar to that of Experiment 2. It is suggested that handedness effects in recall are mediated by motor imagery.     

Confucian Order at the Edge of Chaos: The Science of Complexity and Ancient Wisdom

Many academics extol chaos theory and the science of complexity as significant scientific advances with application in such diverse fields as biology, anthropology, economics, and history. In this paper we focus our attention on structure-within-chaos and the dynamic self-organization of complex systems in the context of social philosophy. Although the modern formulation of the science of complexity has developed out of late-twentieth-century physics and computational mathematics, its roots may extend much deeper into classical thinking. We argue here that the essential ideas and predictions of the science of complexity are found within the social ordering principle of li (the rites) in Confucius's Analects .     

Object perception and object naming in early development

Among our most fundamental capacities are those that allow us to perceive, categorize and name objects. Recently, controversy has surrounded the question of how young children learn names for objects, in particular, the relative roles of perception and higher-level world knowledge. It is well known that adults depend strongly on conceptual knowledge in a variety of categorization tasks, including object naming. We argue, however, that perception may play a special role in early object naming and, in particular, that certain kinds of world knowledge known to guide adult naming may come to guide naming only rather late in development. Building early mechanisms of naming on a perceptual foundation that may be encapsulated, and thus shut off from more reflective processes, may explain in part why young children can easily and rapidly learn names for things from the adults around them, despite the fact that adults and children may possess very different conceptual organizations.     

Latency differences to monochromatic stimuli measured by disjunctive reaction time.

Two studies were done in order to assess the effects of wavelength on visual perceptual latency as measured in a disjunctive RT paradigm. The results of the first study, though not statistically significant, suggested a trend toward shorter RT to longer wavelength stimuli. In the second study, using well-practiced subjects, significant differences were found between disjunctive RT to red and green stimuli. The results suggest that latency differences as a function of wavelength are demonstrable in an experimental situation in which the subject must react to chromatic information, as differentiated from brightness information.
