Additive, interactive, and nonlinear models of alcohol expectancy values were compared using survey data from 1,758 high school students. Expectancies and values independently predicted drinking in the additive model. Expectancies were more important as predictors than were values, and negative expectancies were more important than positive expectancies. Significant expectancy-value interactions also were found. Drinking was highest when positive consequences were believed to be likely and desirable and was lowest when negative consequences were believed to be likely and undesirable. Significant nonlinearities indicated that beliefs about negative consequences had greater effects at lower levels of likelihood and evaluation whereas beliefs about positive consequences had greater effects at higher levels of likelihood and evaluation. However, the interactive and nonlinear effects were small.  相似文献

A parallel input serial analysis (PISA) model of word processing was developed and tested. The goal was to expand on the "critical processing duration" hypothesis of Johnson, Allen, and Strand (1989) so that both single-word and multiple-word presentation, letter detection data could be explained. In Experiments 1-3 four different word frequency categories on a single-presentation, letter detection task were used. These three experiments indicated that there was a curvilinear relationship between word frequency and letter detection reaction time (RT). That is, letter detection RTs for medium-high-frequency words were significantly longer than letter detection RTs for very-high-, low-, and very-low-frequency words. These results support the PISA model rather than the Healy, Oliver, and McNamara (1987) version of the unitization model. In Experiments 4-5 multiple-presentation (i.e., two words), letter detection tasks were used. The PISA model could also account for the results from these two experiments, but the unitization model could not.  相似文献

The occurrence of discrimination in the real world is difficult to determine objectively, as it is defined in part by intentions. The perception of discrimination may therefore be influenced by one's interpretation of the intentions of others. In order to examine psychological characteristics that influence the perception of ethnic discrimination, 164 Armenian, Mexican American, and Vietnamese adolescents completed measures of perceived discrimination (PD), self-esteem, mastery, depression/anxiety, intergroup competence, and ethnic identity, as well as demographic variables. A path analysis showed that higher depression/anxiety scores and lower intergroup competence predicted more PD; depression/anxiety and intergroup competence were in turn predicted by self-esteem and mastery, respectively. Birthplace and socioeconomic status had an indirect effect on PD, via intergroup competence. The results suggest the importance of psychological variables in the perception of discrimination.  相似文献

Definitions of what features constitute cultural behaviour, and hence define cultures are numerous. Many seem designed to describe those aspects of human behaviour which set us apart from other animals. A broad definition prescribing that the behaviour is: learned; learned socially; normative and collective is considered to apply to several species of great ape. In this paper, I review observations and experiments covering a suite of different behavioural characteristics displayed in members of the bowerbird family (Ptilonorhynchidae) and ask whether they fulfil these criteria. These include vocalisations, bower design, decoration use, bower orientation and display movements. Such a range of behaviours refutes the suggestion that these species are “one-trick ponies”—a criticism that is often levelled at claims for culture in non-primate species. I suggest that, despite a paucity of data in comparison with primate studies, it could be argued that bowerbirds may be considered to fulfil the same criteria on which we base our use of the term culture when applied to our close relatives, the great apes. If bowerbirds do have cultures, then their unusual natural history makes them a highly tractable system in which questions of social learning and culture can be tackled.  相似文献

We investigated the question of whether comprehenders mentally simulate a described situation even when this situation is explicitly negated in the sentence. In two experiments, participants read negative sentences such as There was no eagle in the sky, and subsequently responded to pictures of mentioned entities in the context of a recognition task. Participants' responses following negative sentences were faster when the depicted entity matched rather than mismatched the negated situation. These results suggest that comprehenders simulate the negated situation when processing a negated sentence. The results thereby provide further support for the experiential-simulations view of language comprehension.  相似文献

A new generational cohort is emerging from the Millennial market segment as a result of cataclysmic events that have occurred since 2008. Interviews with college upperclassmen in the United States identified significant events influencing their values, the values arising from these events, and new values not associated with older Millennials. The most important events identified included the Great Recession, 9/11, and the election of the first African-American president. Values of Millennials were assessed in online surveys of college juniors and seniors in the United States in the fall of 2009 and 2010 and among older Millennials, aged 27–31, during the summer of 2010. The values most strongly differentiating the younger and older Millennials were “piety” and “thrift.” Younger Millennials in the United States are less thrifty and more secular and sexually permissive than older Millennials. They are also less patriotic and less concerned about politics, sustainability, saving, and making mistakes in life. This suggests a splintering of the Millennials cohort as a result of the Great Recession and the potential emergence of a younger “entitlement” cohort. It also suggests further investigation of cross-national value shifts among younger Millennials, prompted by the Great Recession. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献
