Cognitive Processes in Bilinguals (Human Cognition)

克罗尔博士正在进行的研究旨在测试和开发一种模型， 双语记忆表征。 该模型提出， 在连接的强度上存在不对称， 不同语言中的概念中的词， 学习第二语言的方式。 早期 第二语言学习的各个阶段，第二语言学习者是 假设依赖于第一语言来调解访问 意义 随着第二语言的流利程度提高， 一个直接的意义的途径成为可能。 这个目标 更大规模的研究是确定介导认知的因素， 成人第二语言学习者的变化。 该项目将 进一步检验所提出的双语记忆表征模型 通过检查转移发生的条件， 语言，并通过确定个人业绩的方面， 第一语言预测第二语言的获得 流畅 主办机构的互动活动包括： 关于双语的研究生研讨会;有女大学生参加 在研究项目的主办机构;并组织一个 研究生系列座谈会和非正式辅导研讨会 女学生 本项目进一步促进了VPW计划的目标，即（1） 为妇女提供机会， 工程和科学的学科由NSF支持， (2)提高女科学家和女工程师的知名度 受雇于工业、政府和学术机构。 通过 鼓励妇女参与科学，这是一个宝贵的 投资于国家未来的科学活力。

Dr. Kroll's ongoing research seeks to test and develop a model of memory representation in the bilingual. The model proposes that there are asymmetries in the strength of the connections between words in concepts in different languages that are a consequence of the manner in which the second language is acquired. During early stages of second language learning, the second language learner is hypothesized to rely on the first language to mediate access to meaning. As a greater fluency in the second language is achieved, a direct access to meaning becomes possible. The goal of this larger research is to identify the factors that mediate cognitive change for the adult second language learner. This project will further test the proposed model of bilingual memory representation by examining the conditions under which transfer occurs across languages, and by identifying aspects of individual performance in the first language that predict the attainment of second language fluency. Interactive activities at the host institution include: teaching a graduate seminar on bilingualism; involving undergraduate women at the host institution in the research project; and organizing a colloquium series and informal mentoring seminar for graduate student women. This project furthers VPW program objectives which are (1) to provide opportunities for women to advance their careers in engineering and in the disciplines of science supported by NSF and (2) providing greater visibility for women scientists and engineers employed in industry, government, and academic institutions. By encouraging the participation of women in science, it is a valuable investment in the Nation's future scientific vitality.
