The observation of a bilingual advantage in executive control tasks involving inhibition and management of response conflict suggests that being bilingual might contribute to increased cognitive reserve. In support of this, recent evidence indicates that bilinguals develop Alzheimer's disease (AD) later than monolinguals, and may retain an advantage in performance on executive control tasks. We compared age at the time of receiving an AD diagnosis in bilingual Welsh/English speakers (n = 37) and monolingual English speakers (n = 49), and assessed the performance of bilinguals (n = 24) and monolinguals (n = 49) on a range of executive control tasks. There was a non‐significant difference in age at the time of diagnosis, with bilinguals being on average 3 years older than monolinguals, but bilinguals were also significantly more cognitively impaired at the time of diagnosis. There were no significant differences between monolinguals and bilinguals in performance on executive function tests, but bilinguals appeared to show relative strengths in the domain of inhibition and response conflict. Bilingual Welsh/English speakers with AD do not show a clear advantage in executive function over monolingual English speakers, but may retain some benefits in inhibition and management of response conflict. There may be a delay in onset of AD in Welsh/English bilinguals, but if so, it is smaller than that found in some other clinical populations. In this Welsh sample, bilinguals with AD came to the attention of services later than monolinguals, and reasons for this pattern could be explored further.  相似文献

Infants can see someone pointing to one of two buckets and infer that the toy they are seeking is hidden inside. Great apes do not succeed in this task, but, surprisingly, domestic dogs do. However, whether children and dogs understand these communicative acts in the same way is not yet known. To test this possibility, an experimenter did not point, look, or extend any part of her body towards either bucket, but instead lifted and shook one via a centrally pulled rope. She did this either intentionally or accidentally, and did or did not address her act to the subject using ostensive cues. Young 2‐year‐old children but not dogs understood the experimenter's act in intentional conditions. While ostensive pulling of the rope made no difference to children's success, it actually hindered dogs' performance. We conclude that while human children may be capable of inferring communicative intent from a wide variety actions, so long as these actions are performed intentionally, dogs are likely to be less flexible in this respect. Their understanding of communicative intention may be more dependent upon bodily markers of communicative intent, including gaze, orientation, extended limbs, and vocalizations. This may be because humans have come under selective pressure to develop skills for communicating with absent interlocutors – where bodily co‐presence is not possible.  相似文献

Alastair Logan has argued for the existence of a post-baptismalanointing with ointment in parts of the ‘great church’of second-century Syria and Asia Minor. He has proposed thatthis rite fell into desuetude but found new life in the fourthcentury. Logan's arguments depend especially on Ignatius’Letter to the Ephesians 17.1, the blessing at the end of theCoptic Didache 10.7, and the version of this prayer in ApostolicConstitutions 7.27. However, Logan's evidence lacks convincingcompleteness for three reasons. First, Ignatius’ Letterto the Ephesians says too little about the anointing practisedin communities he judged orthodox to serve as a witness fora post-baptismal ointment rite in these churches. Second, Logan'sargument that the prayer at the end of the Coptic Didache 10.7refers to ointment and is an original part of this documentfails to answer sufficiently too many questions and counter-argumentsfound in the literature. Third, his argument for supposing thatApostolic Constitutions 7.27 proposes a ritual innovation consideredessential by the redactor depends on the misreading of somepassages and on the assertion of divergent interpretations ofthe baptismal ointment in this work which comparison with otherAntiochene sources shows to be unjustified.  相似文献

Research consistently shows part- and full-time workers to be different on a variety of characteristics such as job satisfaction, organizational commitment and intentions to leave the organization. This study challenges the commonly accepted argument that these differences are due to the different structural conditions of work that are faced by part- and full-time workers. The possibility that these differences are the consequence of at-entry differences in dispositions and orientations to work is tested on a sample of part- and full-time registered nurses who had just begun employment. With one exception the part-and full-time employees were found to be the same on fourteen at-entry characteristics. These results strongly suggest that it is the structural conditions of work that produce the often observed differences found between part- and full-time workers.An earlier version of this paper was presented at the 1991 Midwest Sociological Society Meetings, Des Moines, Iowa, April 11–14. Support for the original data collection came from the Division of Nursing of the Health Resources and Services Administration (R01 NU01050-01A1). Joanne McCloskey is to be thanked for allowing us to use this data set.  相似文献

Since the 1970s, some religious practitioners of the contemporary Pagan movement (a.k.a. Neo-Paganism) have embraced spiritual BDSM, or “sacred kink,” as a spiritual discipline relating to their tradition. The “sex wars,” debates around pornography, prostitution, and sadomasochism, have appeared in the history of Wicca and contemporary Paganism. Pagan feminists have brought theological questions to the same debates. They have focused on the Wiccan Rede (“harm none”) and the affirmation of pleasure in Doreen Valiente’s Charge of the Goddess that states that, “All acts of pleasure are [the Goddess’s] rituals.” While support for BDSM has become the dominant public perspective in twenty-first-century Paganism, the movement’s late twentieth-century history includes instances of anguish as individuals wrestled with their personal sexual desire and their feminist principles.  相似文献

Using data from two large multinational samples, this research sought to contribute to our knowledge of international organizational behaviour by examining the cross‐national generalizability of organizational commitment. Sample 1 included employees of 10 subsidiaries of a large multinational organization, whereas Sample 2 relied on data collected in 25 nations in the context of a large opinion survey. Results in both samples supported the expectation that measures of commitment would be more susceptible to measurement non‐equivalence than measures of job satisfaction. Differences in relationships between commitment and satisfaction across countries were observed in both samples, as were differences in mean commitment levels. Nation‐level individualism/collectivism (I/C) failed to account for the observed differences, however, suggesting that commitment and I/C are largely independent, despite theoretical arguments to the contrary. Results of the study suggest that despite some cross‐national variation, differences in commitment across national boundaries are small and empirically unrelated to I/C.  相似文献

One problem of interpreting research on subconscious processing is the possibility that participants are weakly conscious of the stimuli. Here, we compared the fMRI BOLD response in healthy adults to clearly visible single letters (supraliminal presentation) with the response to letters presented in the absence of any behavioural evidence of visibility (subliminal presentation). No letter catch trials served as a control condition. Forced-choice responses did not differ from chance when letter-to-background contrast was low, whereas they were almost 100% correct when contrast was high. A comparison of fMRI BOLD signals for supraliminal and subliminal letters with the control trials revealed a signal increase in left BA 37 (fusiform gyrus). Comparison of supraliminal with subliminal letters showed a significant increase in the right inferior frontal gyrus (BA 44, partly extending to BA 9 and BA 45, as well as BA 46). Finally, a comparison of subliminal with supraliminal letters showed increases in the left middle temporal gyrus (BA 21) and the right extrastriate cortex (BA 19).  相似文献
