Genes, environment, and dyslexia the 2005 Norman Geschwind memorial lecture

This article presents an overview of some methods and results from our continuing studies of genetic and environmental influences on dyslexia, and on individual differences across the normal range that have been conducted over the past 25 years in the Colorado Learning Disabilities Research Center (CLDRC) and in related projects. CLDRC investigators compare the similarities of identical twin pairs who share all their genes and fraternal twins who share half their segregating genes to assess the balance of genetic, shared family environment, and nonshared environment influences on dyslexia and on individual differences across the normal range. We have learned that among the children we have studied in Colorado, group deficits in reading (dyslexia) and individual differences in reading across the normal range are primarily due to genetic influences, and these genetic influences are often shared with some of the same genetic influences on deficits and individual differences in language and ADHD. We have also learned from our molecular-genetic linkage studies that there are regions on several chromosomes likely to contain genes that influence dyslexia. Several specific genes within these regions have been tentatively identified through molecular-genetic association analyses, but much more research is needed to understand the pathways among specific genes, regions of noncoding DNA that regulate the activity of those genes, the brain, and dyslexia. I conclude with a discussion of our research on individual differences in early reading development, on the role of early learning constraints in dyslexia, and on how genetic influences are expressed through their interaction and correlation with the environment.

分布式认知视角下促进元认知发展研究——基于多媒体环境

分布式认知理论的提出,为研究认知活动提供了全新的视角,也为元认知培养方式提供了新的可能性。分布式认知理论强调媒体的作用,多媒体环境不仅能为外部表征提供多种辅助手段,还能为认知活动提供具体情境。在多媒体环境下,直观的外部表征、可视化的知识交流和实时线索的提供为元认知培养提供了全新的视角。     

鲁迅形象建构的认知视野与文化阐释

鲁迅形象建构的内在机制是鲁迅精神资源的确立及扩散,其生成的逻辑基点是文化认同危机与现代"形象范式"的找寻。历代学人的学术阐释丰富和延展了鲁迅形象的精神内涵,当然也存在着无法回避的"误读"现象。不同文化语境的烛照则使"鲁迅本体"被构织成为文化场域中有机构成要素,呈现出具有历史、文化、审美特性的鲁迅形象。
