In a series of three experiments we investigated syntactic priming using a sentence recall task. Participants read and memorized a target sentence for later recall. After reading a prime sentence and engaging in a distraction task, they were asked to produce the target sentence aloud. Earlier investigations have shown that this task is sensitive to a syntactic priming effect. That is, the syntactic form of the prime sentence sometimes influences the syntactic form of the recalled target. In this paper we report on a variation on this task, using Spanish-English bilingual participants. In the first two experiments we replicated the prepositional phrase priming effect using English target sentences and Spanish prime sentences. In the final experiment we investigated two additional syntactic forms, using Spanish target sentences and English prime sentences. Implications for models of syntax generation and bilingual speech production are discussed. 相似文献

Despite their frequency in conversational talk, little is known about how ums and uhs affect listeners' on-line processing of spontaneous speech. Two studies of ums and uhs in English and Dutch reveal that hearing an uh has a beneficial effect on listeners' ability to recognize words in upcoming speech, but that hearing an um has neither a beneficial nor a detrimental effect. The results suggest that um and uh are different from one another and support the hypothesis that uh is a signal of short upcoming delay and um is a signal of a long upcoming delay. 相似文献

We investigated how people produce simple and complex phrases in speaking using a newly developed immediate recall task. People read and tried to memorize a target sentence, then read a prime sentence, then did a distractor task involving the prime sentence. Despite the delay and activity between memory and recall, people could still recall the target sentence although the syntactic form of the recalled sentence was influenced by the syntactic form of the prime sentence. This result replicates the syntactic priming effect found with other experimental paradigms. Using this task, we tested how people used abstract syntactic plans to produce simple and complex noun phrases. We found syntactic priming both when targets and prime sentences matched in complexity and when they did not match, suggesting that simple and complex noun phrases are built by the same syntactic routines during speech production. 相似文献

Neuropsychological Characteristics of Adolescents With Conduct Disorder: Association With Attention-Deficit–Hyperactivity and Aggression 总被引:1,自引:0,他引:1

The purpose of this study was to determine whether an association exists between neuropsychological deficits and conduct disorder (CD) with and without concurrent attention-deficit–hyperactivity disorder (ADHD). In addition, we explored the differential neuropsychological performance of aggressive and nonaggressive CD adolescents and the combined effect of this behavioral status and ADHD on performance. Fifty-nine adolescents (mean age of 15.4 years) who met the criteria for CD were compared with 29 controls comparable in age, gender, and socioeconomic status. A neuropsychological battery of current tests measuring executive functions and a battery of language tests were used in the study. Multivariate analyses showed that, compared with controls, CD adolescents had significantly lower verbal skills but did not differ on executive function measures. However, the lower verbal performance of CD adolescents is not explained by the existence of a CD subgroup with concomitant ADHD or aggressiveness. The study confirms with a sample of CD adolescents the association between verbal deficits and antisocial behavior when socioeconomic status is controlled. Our results also demonstrate that CD per se can be a sufficient condition for such deficits. 相似文献

Investing in research is a long-term, risky proposition. In agriculture, it could take fifteen years or more for a research
finding to show an improvement in a farmer’s field. Yet, research institutions, like other organizations it needs to be evaluated.
For more than twenty years, independent panels of outside experts have evaluated each of the international research centers
that the Consultative Group of International Agricultural Research (CGIAR) supports. This paper examines the evolution of
this review system, outlines the key methodological challenges faced, and draws lessons for others engaged in evaluating research
institutions. It notes that the scope of the CGIAR reviews have been broadened over time in response to users’ concerns. Reviews
now cover four dimensions of performance: research results, quality and relevance of research, vision and strategic directions,
and management efficiency. The methodological challenges faced in measurement, valuation, and attribution are reviewed, along
with practices found to be helpful in addressing these concerns. The paper concludes that the panel approach to institutional
evaluation has served CGIAR’s needs well, and recommends it as an evaluation technique for integrating quantitative and qualitative
dimensions of institutional performance.
His recent work has concentrated on the governance and management of the CGIAR and the individual research centers it supports,
including questions of evaluating management effectiveness. Prior to joining the World Bank in 1979, he was Assistant Professor
of Political Science at Bogazici University (Istanbul) and Senior Research Director of Systems Research Incorporated (Lansing,
Michigan). 相似文献

‘healing stories' are part of an emergent narrative literature in psychology and counselling. This research explored the subjective experience of ‘healing stories’ within the context of individual's life narratives. A grounded theory (Strauss and Corbin, 1990) method of analysis was used to generate and analyse six participant's life narratives. Analysis of these accounts revealed three categories. The first is the context of struggle that preceded the healing process. participants told of struggle in their relationships with others as well as turmoil in their experience of themselves. The second category, the healing process reflected the participants' growing awareness of life's existential givens (Yalom, 1980). This represented a personal exploration that opened lparticipants to a ‘healing story’ that offered them an insight into choices and possibilities for liberation. The third category illustrated that in the ongoing struggle the ‘healing story’ has continued to provide inspiration in the participants' lived experience as an ‘evoked companion’ (Stern, 1985). This research posited a core dynamic whereby participants' experience of their ‘healing story’ provided not only an initial inspiration that was healing but also, in their ongoing struggle, the ‘healing story’ continued to inspire their lived experience. 相似文献

University reform encompasses an increased emphasis on the social and emotional development of students. In particular, the development of caring, empathy, and community are emphasized. This team of psychology professors approaches the task of university reform by presenting both its philosophy of diversity inclusion and specific inclusion strategies as means of promoting enhanced development of our students. Although the discipline of psychology is used as an example, the philosophical argument and the strategic approaches may be applied to other disciplines. 相似文献

As the religious diversity of English towns and cities has grown over the past thirty years due to the establishment in some places of sizeable communities of Hindus, Muslims and Sikhs, as well as other faiths, there have been important changes to local public religion. Traditional civic ceremonies, such as Remembrance Sunday, as well as new forms of civic celebration and commemoration, are now increasingly taking account of the diversity of faiths represented in Britain. This paper examines the consequences of religious diversity for English civic religion by looking at some of the traditions of civic ceremonies in England and at the way in which they have been transformed by the changing religious landscape of towns and cities. The paper also explores some of the dilemmas and questions that have emerged both for the Church of England as well as for the other faith communities when it comes to the design and delivery of civic ceremonies. 相似文献

Age differences in accuracy and choosing in eyewitness identification and face recognition 总被引:5,自引:0,他引:5
Studies of aging and face recognition show age-related increases in false recognitions of new faces. To explore implications of this false alarm effect, we had young and senior adults perform (1) three eye-witness identification tasks, using both target present and target absent lineups, and (2) and old/new recognition task in which a study list of faces was followed by a test including old and new faces, along with conjunctions of old faces. Compared with the young, seniors had lower accuracy and higher choosing rates on the lineups, and they also falsely recognized more new faces on the recognition test. However, after screening for perceptual processing deficits, there was no age difference in false recognition of conjunctions, or in discriminating old faces from conjunctions. We conclude that the false alarm effect generalizes to lineup identification, but does not extend to conjunction faces. The findings are consistent with age-related deficits in recollection of context and relative age invariance in perceptual integrative processes underlying the experience of familiarity. 相似文献
