Good luck implies comparison with a worse counterfactual outcome, whereas bad luck implies upward comparisons. People will accordingly describe themselves as particularly lucky after recollecting situations where they avoided something negative, and as particularly unlucky after recollecting episodes in which they missed something positive (Study 1). Upward and downward comparisons can be created by the way a situation develops, and are accentuated by the way a story is told. Good luck stories typically change for the better only in the last stage, whereas bad luck stories show a more steady downward progression (Study 2). This is also reflected in phrases believed to be characteristic of good luck versus bad luck stories, with good luck stories involving surprise and reference to close counterfactuals, whereas bad luck stories focus on initial normal events (Study 3). Good and bad luck imply different orders of events (negative–positive versus positive–negative), so by rearranging the narrative sequence, the same set of outcomes can form the basis for a good luck story as well as a bad luck story (Study 4). The final experiment (Study 5) shows that negative outcome expectations are typical for chance‐determined and uncontrolled situations. Under such circumstances, factual outcomes do not have to be exceptionally good to be considered as lucky. Copyright © 1999 John Wiley & Sons, Ltd.  相似文献

A landmark decision in 2000 by the Federal Court of Australia (FCA) allowed access to medically assisted reproductive technologies (MART) regardless of marital status, i.e. by single women and lesbians. This decision sparked much debate, including comments by the Prime Minister of Australia and hundreds of letters to newspapers around the country. In this study, 180 letters to the editor in two newspapers were analyzed to identify themes and processes relevant to conceptualizing who should have access to MART. Representations of family were particularly evident and themes supported the traditional family structure of a mother, father and children, arguing that access to MART should be restricted to this family form. However, emerging representations of family, based on themes of positive parenting values, independent of gender and number of parents, were also observed, suggesting that political agendas restricting MART to heterosexual family structures are not supported by public consensus, or by the emerging acceptance of alternative family forms.

Right-IFG and pre-SMA are associated with inhibitory responses. We used functional Magnetic Resonance Imaging to explore whether the contralateral homotopic regions can functionally replace them. An adolescent, with an extensive traumatic lesion of the right cerebral hemisphere having occurred 5 years earlier, performed a motor response inhibition task (Go/Nogo), which was properly accomplished and associated to activations in the left-IFC, precuneus and occipital cortex. Such functional remodelling is in line with the theory of ‘near equipotentiality’ of the cerebral hemispheres.  相似文献

In cancellation tasks, patients with unilateral spatial neglect typically fail to mark targets within the side of the sheet contralateral to the side of the lesion (contralesional). Moreover, they can show a perseverative behaviour, which consists in repeatedly cancelling stimuli, mainly in the side of the display ipsilateral to the side of the lesion (ipsilesional). We investigated in 13 right‐brain‐damaged patients with left spatial neglect and perseverative behaviour whether and how different densities of horizontal targets modulated omission and perseverative errors. We found that the density of targets modulated the patients’ distribution of neglect (area of omission), but not its extent, as indexed by the percentage of omissions. Specifically, the area of omissions tightened when target density increased leftwards. On the other hand, target density did not affect the distribution of perseverative behaviour (area of perseveration), as well as its extent, as indexed by the percentage of perseverations. Correlation analyses showed that both the extent and the distribution of omissions were positively correlated to clinical measures of spatial neglect. Conversely, perseverations did not show such a correlation. These findings support the view that two different pathological mechanisms might be involved in left spatial neglect and in ipsilesional perseverative behaviour.  相似文献

In two experiments, we investigated how priming European identity as common project versus common heritage affects participants' cooperation in a social dilemma; an additional aim was to explore the mediators involved in the process. In the first experiment, 82 students played a public good dilemma with a European bogus partner and then completed self‐report measures of identification with the European Union (EU), group‐based trust and collective interest. Results showed that priming a common project‐based but not a common heritage‐based European social identity fostered cooperative behaviour; this effect was mediated by two sequential mediators: the common project prime increased participants' strength of identification with EU (mediator 1) which, in turn, positively affected group‐based trust (mediator 2), fostering greater cooperation. Experiment 2 was conducted with a similar procedure on a sample of 124 students, using a different measure of trust and changing the order of mediators. Results supported those of previous experiment: Priming a project‐based EU identity content (compared to heritage‐based one) had significant direct and indirect effects on cooperation.  相似文献

The aim of the present study was to explore the ability of personality to predict academic performance in a longitudinal study of a Swedish upper secondary school sample. Academic performance was assessed throughout a three‐year period via final grades from the compulsory school and upper secondary school. The Big Five personality factors (Costa & McCrae, 1992 ) – particularly Conscientiousness and Neuroticism – were found to predict overall academic performance, after controlling for general intelligence. Results suggest that Conscientiousness, as measured at the age of 16, can explain change in academic performance at the age of 19. The effect of Neuroticism on Conscientiousness indicates that, as regarding getting good grades, it is better to be a bit neurotic than to be stable. The study extends previous work by assessing the relationship between the Big Five and academic performance over a three‐year period. The results offer educators avenues for improving educational achievement.  相似文献

Peers may influence the body image concerns and disordered eating behaviours of adolescent girls through the creation of appearance cultures within friendship cliques. The present study investigates the role of friendship cliques and school gender composition in impacting upon adolescent girls’ body image concern and disordered eating behaviours, using hierarchical linear modelling (HLM), a statistical procedure employed in the analysis of nested data. A sample of 156 girls was drawn from four private schools located in the capital city of Western Australia (one single-sex school and three mixed-sex schools). Eighty students from the single-sex school and 76 female students from the mixed-sex schools, comprising 35 friendship cliques, completed questionnaires assessing body image, disordered eating, and a range of variables that have previously been associated with body image concern and disordered eating, including appearance-based social comparison, frequency of appearance-based conversation, appearance-based criticism, friends’ concern with thinness, media influence and media pressure. Hierarchical linear modelling analyses found that friendship cliques in all-girls schools exhibited similar levels of body image concern and dieting behaviours, with various peer and other media influence variables accounting for these similarities. Friendship cliques in mixed-sex schools were not found to be similar with regard to body image concern or disordered eating. These findings support the notion that friendship groups can be an important source of influence on the body image concerns of adolescent girls in single-sex schools, and show that both individual and friendship clique level measures of attitudes and behaviours make independent contributions to the prediction of these body image concerns.  相似文献

This study assessed work-related and driver-related factors in fatigue among Finnish heavy vehicle drivers. 683 professional drivers responded to a questionnaire, 27.8% of whom reported often feeling fatigue during their work shifts. Of the respondents, 27.5% reported having momentarily fallen asleep at the wheel while driving during the past year. Almost half (46.8%) of the fatigued drivers estimated the reasons for momentarily falling asleep were work-related. Long working shifts and short sleeps significantly increased the risk of momentarily falling asleep at the wheel. The risk of fatigue was the highest for the drivers who were unable to choose the time of their breaks.  相似文献

The well established effect of word frequency on adult's picture naming performance is now called into question. This is particularly true for variables which are correlated with frequency, as is the case of age of word acquisition. Since the work of [Carrol and White, 1973] there is growing agreement among researchers to confer an important role in lexical access to this variable. Indeed, it has been shown ( [Hodgson and Ellis, 1998]) that for normal English-speaking adults only the variables 'age-of-acquisition' and 'name agreement' are independent predictors of naming success among the various variables considered. However, when brain-damaged subjects with and without degenerative pathologies are studied, word frequency and word length as well as concept familiarity all give significant effects ( [Hirsh and Funnell, 1995]; [Lambon Ralph et al., 1998]; [Nickels and Howard, 1995]). Finally, it has been suggested that the production of specific error types may be related to such variables. According to [Nickels and Howard, 1994] the production of semantic errors is specifically affected by 'imageability' and in the recent study by [Kremin et al., 2001] 'age of acquisition' predicts (frank) word finding difficulties.  相似文献
