O’Brien maintains that the behavior of football fans should be analyzed not merely in terms of individual behavior but also in terms of group dynamics. He found in the Milltown Supporters Club several such groups. 相似文献

The effects of the frequency of a surname in the population and of the distinctiveness of a face on the latency to name famous faces were explored. Distinctive faces were named more quickly than were typical faces. Celebrities with low-frequency surnames were named faster than celebrities with high-frequency surnames, but only if their faces were distinctive. Subsequent experiments showed that the effect of surname frequency could not be attributed to differences in the articulatory onsets of the surnames and was not present in a task that did not require a naming response. Experiments in which surnames were taught to previously unfamiliar faces showed that familiar surnames (e.g. the surnames of celebrities) were produced more rapidly than were unfamiliar surnames. If familiar surnames were taught, no effect of surname frequency was observed. It is concluded that lexical access to peoples' names is frequency sensitive—surnames shared by few individuals are accessed faster than are high-frequency surnames. However, when learning names to unfamiliar faces, familiar surnames (i.e. the surnames of people already known to the subject) are learned and accessed more quickly than unfamiliar surnames. 相似文献

Multisensory reweighting (MSR) is an adaptive process that prioritizes the visual, vestibular, and somatosensory inputs to provide the most reliable information for postural stability when environmental conditions change. This process is thought to degrade with increasing age and to be particularly deficient in fall-prone versus healthy older adults. In the present study, the authors investigate the dynamics of sensory reweighting, which is not well-understood at any age. Postural sway of young, healthy, and fall-prone older adults was measured in response to large changes in the visual motion stimulus amplitude within a trial. Absolute levels of gain, and the rate of adaptive gain change were examined when visual stimulus amplitude changed from high to low and from low to high. Compared with young adults, gains in both older adult groups were higher when the stimulus amplitude was high. Gains in the fall-prone elderly were higher than both other groups when the stimulus amplitude was low. Both older groups demonstrated slowed sensory reweighting over prolonged time periods when the stimulus amplitude was high. The combination of higher vision gains and slower down weighting in older adults suggest deficits that may contribute to postural instability. 相似文献
