When thinking under uncertainty, people often do not consider appropriately each of the relevant branches of a decision tree, as required by consequentialism. As a result they sometimes violate Savage's sure-thing principle. In the Prisoner's Dilemma game, for example, many subjects compete when they know that the opponent has competed and when they know that the opponent has cooperated, but cooperate when they do not know the opponent's response. Newcomb's Problem and Wason's selection task are also interpreted as manifestations of nonconsequential decision making and reasoning. The causes and implications of such behavior, and the notion of quasi-magical thinking, are discussed. 相似文献

Associations of two different response sets on the Infrequent Response Index of the Strong Interest Inventory (SII) were examined. In one, participants responded to each item randomly; in the other, participants deliberately misrepresented their responses. The finding of scores higher than those proposed in the SII manual for the Infrequent Response Index suggests an alternative interpretation of this critical index. 相似文献

This study examined the career aspirations of pregnant teens enrolled in a program designed to minimize their chances of dropping out of high school. The teens completed a demographic data form that included questions on their career aspirations. The data were coded by Holland type using the Dictionary of Holland Occupational Codes. Trends were discussed in light of the future labor market and critical need for career counseling for this at-risk population. 相似文献
