Research reveals pervasive optimism in people's comparative risk judgements such that people believe they are less likely than others to experience negative events. Two studies explored the extent to which people are consistent in their comparative risk judgements across time and events. Both studies found strong evidence for consistency across time and some evidence for consistency across events. The consistency across time and events was moderated by experience. Specifically, when viewed together, the studies suggest that experience produces an initial decrease in the consistency of comparative judgements (Study 2), followed by greater consistency in subsequent judgements (Study 1). The discussion focuses on reconciling evidence demonstrating consistency with evidence demonstrating variability. 相似文献

Studies on suicide among police show inconsistent results, thereby contributing to considerable speculation regarding why police officers commit suicide. The present paper is the first nationwide study on suicidal ideation and attempts among police. 3,272 Norwegian police completed Paykel's Suicidal Feelings in the General Population questionnaire. Lifetime prevalence of specific questionnaire items ranged from 24% for the feeling that life was not worth living, 6.4% for having seriously considered suicide, and 0.7% for attempted suicide. Independent predictors of serious suicidal ideation were marital status, subjective health complaints, reality weakness, anxiety, and depression. Serious suicidal ideation was mainly attributed to personal and family problems. 相似文献

In free recall tasks, when low- and high-frequency items are mixed within the to-be-remembered lists, the usual recall advantage
found for high-frequency words is eliminated or reversed. Recently, this mixedlist paradox has also been demonstrated for
short-term serial recall (Hulme, Stuart, Brown, & Morin, 2003). Although a number of theoretical interpretations of this mixed-list
paradox have been proposed, researchers have also suggested that it could simply be a result of participant-controlled strategies
(M. J. Watkins, LeCompte, & Kim, 2000). The present study was designed to assess whether this explanation could be applied
to immediate and delayed serial recall. The results showed that high-frequency words were recalled better than low-frequency
words in pure lists, but that this effect was eliminated in mixed lists, whether they were given under intentional or incidental
learning conditions. This pattern suggests that the mixed-list paradox cannot be explained by participant-controlled strategies. 相似文献

Four experiments are reported, investigating the mechanisms underlying the compatibility effect in the Implicit Association Test (IAT; Greenwald, McGhee, & Schwartz, 1998). All experiments involved two IATs: flower IAT, in which the target categories were flowers and insects, and number IAT, involving even and odd numbers as target categories. In Experiment 1, using the standard IAT procedure, the two IATs produced equal IAT effects, despite large differences in rated valence contrast between flowers and insects and between even and odd numbers. Experiment 2 used a procedure developed by Klauer and Mierke (2005) and produced results consistent with the view that valence plays a role in the flower IAT but not in the number IAT. Experiments 3 and 4 used manipulations similar to those developed by Rothermund and Wentura (2004) and showed that these manipulations affected the flower IAT and number IAT differently. The results provide converging evidence that the two types of IAT effects-one based on valence and one based on familiarity-are empirically dissociable.Experiments 1and 2 reported in this paper were conducted as an honours project by Marie Peek-O'Leary under the supervision of Sachiko Kinoshita. Parts of this paper were presented at the 44th Annual Meeting of the Psychonomic Society held in Vancouver, Canada, in November, 2003. 相似文献

Sign languages modulate the production of signs in space and use this spatial modulation to refer back to entities—to maintain coreference. We ask here whether spatial modulation is so fundamental to language in the manual modality that it will be invented by individuals asked to create gestures on the spot. English speakers were asked to describe vignettes under 2 conditions: using gesture without speech, and using speech with spontaneous gestures. When using gesture alone, adults placed gestures for particular entities in non-neutral locations and then used those locations to refer back to the entities. When using gesture plus speech, adults also produced gestures in non-neutral locations but used the locations coreferentially far less often. When gesture is forced to take on the full burden of communication, it exploits space for coreference. Coreference thus appears to be a resilient property of language, likely to emerge in communication systems no matter how simple. 相似文献

In immediate serial recall, high-frequency words are better recalled than low-frequency words. A prevalent interpretation of this effect suggests that, at the point of recall, degraded representations undergo a reconstruction process calling upon long-term knowledge of the to-be-remembered items. Recently, Stuart and Hulme (2000) following Deese (1960), suggested that high-frequency items are better recalled due to their better long-term associative links. Their results revealed that a familiarisation procedure involving repeated presentations of the to-be-remembered items in pairs abolished the usual frequency effect. In the experiment reported here, an alternative interpretation of this result is examined. Prior to the memory task, subjects received either no familiarisation, item familiarisation, or pair familiarisation. Both item and pair familiarisation improved the item recall of low-frequency items to the same extent, suggesting that increased familiarity can account for the co-occurrence effect. 相似文献

Social anxiety disorder, whose onset peaks in adolescence, is associated with significant impairment. Despite the availability
of effective treatments, few affected youth receive services. Transporting interventions into schools may circumvent barriers
to treatment. The efficacy of a school-based intervention for social anxiety disorder was examined in a randomized wait-list
control trial of 35 adolescents (26 females). Independent evaluators, blind to treatment condition, evaluated participants
at preintervention, postintervention, and 9 months later. Adolescents in the intervention group demonstrated significantly
greater reductions than controls in social anxiety and avoidance, as well as significantly improved overall functioning. In
addition, 67% of treated subjects, compared to 6% of wait-list participants, no longer met criteria for social phobia following
treatment. Findings support the possible efficacy of school-based intervention for facilitating access to treatment for socially
anxious adolescents. 相似文献

Effects of modeling and contingent praise on infant imitation of three different responses was analyzed. Generalization to nonreinforced probe models was assessed both within and across response types. Three 12- to 14-month-old infants and their mothers participated in this study. During baseline the mothers provided models only. During treatment mothers modeled and also praised contingent upon infant matching of the training models. During interspersed probe trials the mothers modeled different responses, which, if matched by the infant, produced no praise. The three responses modeled were motor-with-toy, motor-without-toy, and vocal responses. The dependent measure was the percentage of maternal models that were matched by the infant within 6 s. Nonmatching responses of the same response type were also measured. Results showed a systematic increase in the percentages of training and probe models matched by the three infants following the introduction of the model-and-praise treatment condition. Nonmatching responses did not systematically increase. Thus, imitation generalized within response class, but not across response classes. 相似文献

Employees often evaluate leadership potential when selecting applicants for jobs that require leadership ability (e.g., supervisors, firefighter captains). Research has shown that influencing others is an important part of being an effective leader, yet employers rarely explicitly consider applicants' use of influence tactics when evaluating applicants' leadership potential. The purpose of this study was to explore applicant use of influence tactics in an employment interview and to determine how such use relates to interview ratings. The authors observed firefighter applicants' behavior during a selection role-play interview and recorded their use of influence tactics. Results indicated that firefighter applicants used soft tactics (e.g., ingratiation, rational persuasion) significantly more frequently than they used hard tactics (e.g., pressure, coalition). Soft tactic use was positively correlated with interview ratings. 相似文献
