The acceptance of migrant populations and the definition of an “appropriate” migrant are controversial issues in many countries. The present research focuses on the ideological determinants of how newcomers are evaluated by a host population in a Western country with a strongly rooted meritocratic ideology. We carried out two studies to examine how the expression of meritocratic beliefs by a male potential migrant affects the way he is evaluated by the host population. We measured the host population's perception of the potential migrant's ability to integrate into society, his tendency to adopt the host country's culture, and the general desirability of his world vision for all newcomers. We also noted the host population's judgments of the target's agency and communality. The results showed that a potential newcomer who expresses a strong (vs. weak) belief in a just world (Study 1) or an internal (vs. external) locus of control (Study 2) is evaluated more favorably by the host population. In addition, judgments of the target's integration capacity were only mediated by his perceived agency. We discuss these results in the light of work on the meritocratic ideology and intercultural relations. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

When participants are asked to recall lists of items in the reverse order, known as backward recall, several benchmark memory phenomena, such as the word length effect, are abolished (Bireta et al. Memory & Cognition 38:279–291, 2010). Bireta et al. (Memory & Cognition 38:279–291, 2010) suggested that in backward recall, reliance on order retention is increased at the expense of item retention, leading to the abolition of item-based phenomena. In a subsequent study, however, Guérard and Saint-Aubin (in press) showed that four lexical factors known to modulate item retention were unaffected by recall direction. In a series of five experiments, we examined the source of the discrepancy between the two studies. We revisited the effects of phonological similarity, word length, articulatory suppression, and irrelevant speech, using open and closed pools of words in backward and forward recall. The results are unequivocal in showing that none of these effects are influenced by recall direction, suggesting that Bireta et al.’s (Memory & Cognition 38:279–291, 2010) results are the consequence of their particular stimuli.  相似文献

Bilingual speakers generally manifest slower word recognition than monolinguals. We investigated the consequences of the word processing speed on semantic access in bilinguals. The paradigm involved a stream of English words and pseudowords presented in succession at a constant rate. English-Welsh bilinguals and English monolinguals were asked to count the number of letters in pseudowords and actively disregard words. They were not explicitly told that pairs of words in immediate succession were embedded and could either be semantically related or not. We expected that slower word processing in bilinguals would result in semantic access indexed by semantic priming. As expected, bilinguals showed significant semantic priming, indexed by an N400 modulation, whilst monolinguals did not. Moreover, bilinguals were slower in performing the task. The results suggest that bilinguals cannot discriminate between pseudowords and words without accessing semantic information whereas monolinguals can dismiss English words on the basis of subsemantic information.  相似文献

It is known that visual working memory capacity is limited, but the nature of this limit remains a subject of controversy. Increasingly, two factors are thought to limit visual memory: an object-based limit associated with so-called "slots" models, and an information-based limit associated with resource models. Recently, Barton, Ester, and Awh (2009) introduced a measure of mnemonic resolution, which they dubbed c. We show here that c is critically flawed, and cannot be interpreted as a measure of resolution. We recommend strongly against its use and interpretation, and suggest alternatives approaches for researchers who want to explore mnemonic resolution.  相似文献

Marital breakup has been associated with numerous behavioral problems in children, such as sexual risk behaviors. This research is the first to examine sexual behaviors of Spanish adolescents related to whether their parents were married or divorced. Participants were 342 boys and girls aged between 14 and 18 years. The sample provided confidential information about their sexual behavior and birth control methods. Significant differences were only found in percentages of adolescents who had engaged in mutual masturbation, intercourse, or oral sex, and who had practiced these sexual relations in the last six months, in both cases, they were higher when the parents had broken their marital relationship. Regarding adolescents of divorced parents, engaging in intercourse is more likely in older teenagers who live with a stepparent. Moreover, older adolescents who were younger when parents divorced and who live in a reconstituted family, have more sexual partners. These and other findings are discussed.  相似文献

This paper introduces a summary on how to proceed to conduct a factor analysis when the input data are ipsative. The classical factor analysis procedures cannot be used because the covariance matrix is singular. Additionally, previous research on the optimal conditions to conduct factor analysis for ipsatized data is reviewed, and the results of a simulation study are presented. The study includes conditions of sample size, model complexity, and model specification (correct vs. incorrect). The results suggest that researchers should be careful when factor analyzing ipsatized data, particularly if they suspect that the model is incorrectly specified and includes a smaller number of factors.  相似文献

Every society develops a particular system of beliefs that summarizes its vision of socio-political organization, culture and interpersonal relationships. Each of these three basic dimensions has different forms, depending on the spatial and temporal context of societies. The belief system of the service societies is characterized by a democratic vision of social and political organization, rejection of radical social changes and high levels of interpersonal trust. This paper empirically examines the incorporation and adaptation of the postmodern belief system in a sample of university students. The participants belong to a country that is slowly integrating into the service societies. We used a scale of postmodernity to analyze the incorporation of the postmodern belief system. The results indicate that there is a peculiar combination of the three basic dimensions of the postmodern belief system, where the postmodern conceptions of culture and social relationships have lower acceptance.  相似文献

Perception of social support and functioning of patients with schizophrenia and their primary caregivers and its relationship to quality of life are described. Forty-five patients and their 45 relatives, treated at the Mental Health Services in Arica, Chile, participated. Both patients and caregivers in the study have a poor perception of social support with regard to extra-family people, as well as a low social integration. However, patients showed adequate capacity to function within their immediate family. Unlike what was found in developed countries, these patients showed moderate levels of quality of life, with a strong relationship with perceptions of the social support they receive from family and significant others and the ability to establish and maintain social contacts. Quality of life of primary caregivers is linked to patients' ability to establish and maintain social contacts within the family group, as in other social instances, such as keeping a job. The results of the study suggest the need to consider the design and application of programs of support for these patients and their caregivers, with the central aim of the social functioning of the above-mentioned patients and their familiar and community integration.  相似文献

The objective of this study was to validate in a sample of 205 coronary patients a factor model for the BDI-II, especially a model that would allow for modeling of depressive symptoms after explicitly removing bias related to somatic symptoms of depression that would overlap those of heart disease. Exploratory and confirmatory factor analyses for ordinal data were conducted. A one-factor model, six correlated two-factor models and, derivatives thereof, seven models with a single General Depression factor and two uncorrelated factors, were analyzed. Exploratory analysis extracted two factors, Somatic-affective and Cognitive. Confirmatory factor analyses showed the worst fit for the one-factor model. Two-factor models were surpassed in goodness of fit by the models of general-factor and group factors. Among these, the General, Somatic-affective and Cognitive (G-Sa-C) model of Beck with students is noteworthy. The reduced General, Somatic and Cognitive (G-S-C) model of Ward showed the worst goodness of fit. Our model surpasses the cutoff criteria of all fit indexes. We conclude that the inclusion of a general-factor and group factors in all the models surpasses the results of G-S-C model and, therefore, questions it. The G-Sa-C model is strengthened.  相似文献
