Findings have been reported and replicated indicating group-induced caution at the racetrack and group-induced risk in blackjack gambling. The present research examined the effects of two consistent differences between the blackjack and racetrack situations: (a) the amount of money available to groups versus individuals; and (b) the number of bets made in the postbaseline session. It was found that group-induced caution can occur in the blackjack setting if groups have larger stakes than individuals, as was the case in the racetrack studies, and that this effect disappears over trials, due to group versus individual differences established in the previous blackjack studies. Since current explanations of choice shifts cannot account for the observed trial effects, it was suggested that traditional choice-dilemma material, on which these explanations are largely based, be examined for such effects. Implications of the possible outcomes of such an examination for current group polarization theory were discussed. 相似文献

It has been suggested that asymmetries in the morphological properties of the face contribute to or produce asymmetries in facial emotional expression. Over 50 years of research on hard tissue, soft tissue, and facial surface asymmetries is reviewed here. Generally, it appears that if consistent asymmetry characterizes facial morphology, it is extremely small in magnitude or characterizes regions yet to be examined. In contrast, marked homology and asymmetry in regional size and area has been noted often. At present, it does not appear that asymmetry in facial morphology is associated with facial expressive asymmetry, with the latter more likely to be an outcome of functional brain asymmetry. 相似文献

Female right-handed subjects were presented with a memory set consisting of five unfamiliar female voices. They were then tested with a recognition procedure in which samples of voice, memory set or novel, 2 or 4 sec in duration, were heard in one ear and a competing noise stimulus was heard in the other ear. There was an overall left-ear advantage in accuracy of recognition. This advantage held particularly for identifications of memory-set voices in the second half of trials. Internal analyses indicated that the left-ear advantage could not be attributed to greater retroactive interference during right-ear presentation. Congruent with studies of recognition of unfamiliar faces, the findings suggested right-hemisphere superiority in the recognition of unfamiliar voices. 相似文献

In order to address the issue of whether abstract and concrete objects are categorized similarly, this paper looks at how computer scientists categorize the common concepts of their field. Using the methodology of Rosch, Mervis, Gray, Johnson, and Boyes-Braem (1976) and of Rosch and Mervis (1975) to identify the categorizations used by computer scientists, this study found that the categorization phenomena reported for concrete objects are quite general, operating over a wider range than was previously thought. 相似文献
