Abstract An analogue study investigated the impact of genetic testing on perceptions of disease. Using a 2 × 2 design, participants (n = 212) imagined receiving the information that they were at increased risk for either heart disease or arthritis. The type of risk information was either genetic or unspecified. Presentation of genetic risk information resulted in the condition being perceived as less preventable. Causal models of disease where investigated using principal components analysis. When hem disease was the stimulus condition, attributions to genes and chance were positively associated following unspecified risk information, and negatively associated following genetic risk information. When arthritis was the stimulus condition, presentation of genetic risk information was associated with attributions to genes becoming separated from the other attributions. One explanation for this is that providing genetic risk information may decrease perceptions of a sense of randomness or uncertainty in disease causation. The extent to which these effects occur in clinical populations. and their behavioural consequences. needs to be established. 相似文献

Two studies compared choice and underlying cognitive processes in equivalent decision tasks involving risk and uncertainty (lotteries versus sports gambles including displayed expert probability judgements). In sports gambles, background knowledge was triggered via information on team location, home or away. Otherwise, displayed risk information (stake, winnings, odds, and outcome probabilities) was controlled across gamble type. In a choice study, home win bets were chosen significantly more frequently than draws or away wins, compared to lottery equivalents. In a parallel study eliciting concurrent verbal protocols, participants made fewer evaluations of odds and probabilities, and more statements involving background knowledge in sports gambles. Furthermore, some sports gamble protocols indicated modifications of stated probabilities and decision strategies contingent on domain knowledge. It was concluded that stated probability revision and knowledge-based reasoning are key cognitive processes in sports gambling not normally applied in the lottery paradigms often employed in decision research. 相似文献

ABSTRACT This brief synthesis presents the main points of agreement between Dawson and Jensen's article, “‘Towards a ‘Contextual Turn’ in Visitor Studies: Evaluating Visitor Segmentation and Identity-Related Motivations” (this issue) and Falk's reply, “Contextualizing Falk's Identity-Related Visitor Motivation Model” (this issue), and it highlights important considerations for future research. 相似文献

Symbols are a vital part of our everyday lives. We see them in our homes, in our workplaces, and in our communities. Symbols offer certain measures of beauty and comfort, predictability and reassurance. In times and settings of conflict, however, symbols do much more than that. Symbols can provide meaning for heartfelt convictions and direction for future actions. This article examines symbols used in a time and setting of very real conflict between church and state, particularly as such a conflict centered upon parochial education. The time is immediately before, during, and immediately after World War I. The state under study is Nebraska, as its citizens and officials competed with Lutheran denominations for the loyalty of resident parents and children. 相似文献

Abstract Nigro and Neisser (1983) contrasted two ways of remembering personal experiences: the rememberer may ‘see’ the event from his or her perspective as in normal perception, or ‘see’ the self engaged in the event as an observer would. Several factors contribute to the determination of perspective, but Nigro and Neisser also reported that many subjects claimed they could change to another perspective at will. We sampled personal memories from several life periods and assessed ability to change the initially reported perspective. Changing was easier for recent or vividly recalled events, harder for older and less vividly recalled events. Memory perspectives may differ in other aspects than their imagery. A second study was conducted to determine whether affective experience is altered when perspectives are changed. The affect experienced decreased when shifting from a field to an observer perspective, but did not change with the converse shift. These studies provide further evidence that remembering is more than retrieval. The information that enters awareness is determined by the information sources in memory and the organisational scheme adopted for recollection. 相似文献

While the recent publication of the Hannah Arendt-Martin Heidegger correspondence confirms that there existed a close personal tie between these two thinkers, the relation between their philosophies is far more problematic. This article argues that Arendt's originality presents itself in its full light in her two major theoretical works of the 1950s, Between Past and Future and The Human Condition , when these works are considered to present a thinly veiled, implicit critique of Heidegger's philosophy. Arendt's critique becomes especially visible in the 'existential' role that she attributed to natality in its relation to political action and to remembrance, placing in question the central orientation of Heidegger's existential ontology in terms of being-toward-death. 相似文献

The present study examined cognitive dissonance-related attitude change in the domain of exercise. Experimental participants made a decision to perform a boring exercise task (stepping on a bench/chair) under three different conditions: a free-choice condition (n = 33, Male = 17 female = 16, Age = 14.57), under a no-choice/control condition (n = 28, Male = 15, Female = 13, Age = 14.50), and under a condition that compelled participants to practice bench/chair stepping (forced-choice condition) (n = 31, Male = 15, Female = 16, Age = 14.61). Results showed that participants in the free-choice condition reported more positive attitudes than participants in the control condition and participants in the forced-choice condition. Ancillary analysis indicated that cognitive dissonance is experienced as an aversive state, and that the amount of frustration that participants experienced immediately after the free-choice paradigm predicted attitudes. 相似文献
