A Working Memory Perspective on Language Research——Models and Implications
工作记忆是认知心理学和认知神经学的重要理论概念,它对语言等复杂认知行为的研究具有重大理论意义。通过与短时记忆概念的对比,本文阐述工作记忆概念的具体含义,梳理欧洲和北美具有代表性的、与语言研究密切相关的四种工作记忆理论模型和两种广为采用的研究方法,分析工作记忆对语言习得、言语理解以及传译等语言研究领域带来的重要启示。Working memory(WM) is a key theoretical concept from cognitive psychology and cognitive neuroscience.It has a great deal to offer research into complex cognitive behaviors such as language.This paper clarifies the concept of WM through comparison with the better known concept of short-term memory,and presents a critical review of four influential WM models which are highly relevant to language research and two common research methodologies.The paper also provides an analysis of the implications of WM theories for research into various fields concerning language,including language acquisition,language comprehension,and interpreting(both spoken and signed).国家社科基金项目“手语翻译理论建构”(08CYY005)的阶段性成
Source apportionment of water-soluble ions in spring TSP of Pengjia Islet, Taiwan
于2010年春季,在台湾省北部东海海域彭佳屿岛采集了60个总悬浮颗粒(TSP)样品,用离子色谱测定了8种水溶性离子(Na~+、Mg~(2+)、; Ca~(2+)、K~+、NH_4~+、Cl~-、SO_4~(2-)和NO_3~-)浓度.结合HYSPLIT气团后向轨迹模型、离子化学计量学关系、; 离子相关性分析和主成分分析,探讨了彭佳屿岛春季TSP中水溶性离子的主要来源.结果表明:彭佳屿岛春季TSP中水溶性离子质量浓度顺序依次为SO_4~; (2-)(7.704.53)mug/m~3> Cl~-(6.17 3.85)mug/m~3>Na~+(4.59 ; 2.28)mug/m~3>NO_3~-(4.24 3.07)mug/m~3>NH_4~+(1.53 ; 1.20)mug/m~3>Ca~(2+)(0.95 1.47)mug/m~3>Mg~(2+)(0.59 ; 0.30)mug/m~3>K~+(0.310.17)mug/m~3.其中Cl~-、Na~+和Mg~(2+)全部来源于海洋源;K~+来源较多,除了; 海洋源外,煤和生物质燃烧以及陆源矿物等都可能是彭佳屿岛春季TSP中K~+的来源;60%的Ca~(2+)来源于当地的建筑粉尘;77%的SO_4~(; 2-)源于煤和生物质燃烧释放;NO_3~-主要源于汽车尾气、煤和生物质燃烧等释放;NH_4~+主要来源于二次气溶胶和生物质燃烧等.通过整合本研究; 与前人的观测,发现在春季从中国东北至西北太平洋开阔海域,TSP中Cl~-、Na~+和Mg~(2+)的浓度在空间上呈现逐渐升高趋势,而Ca~(2+; )、K~+、NH_4~+、SO_4~(2-)和NO_3~-的浓度在空间上呈现逐渐下降趋势,显示了TSP中不同水溶性离子在海洋大气传输过程中的空间; 变化特征.In spring of 2010, sixty total suspended particulate (TSP) samples we; collected in Pengjia Islet, northern sea of Taiwan, China. The; concentrations of water-soluble ions (Na~+, Mg~(2+), Ca~(2+), K~+,; NH_4~+, Cl~-, SO_4~(2-) and NO_3~-) in the TSP samples were extracted; and then determined using an Ion Chromatography. Using these data, we; investigated the sources of water-soluble ions by a multiple-technique; analysis combining with the HYSPLIT model, ion stoichiometry,; correlation analysis of water-soluble ions and primary component; analysis. According to a decreasing order in the average mass; concentration, these ions ranked as SO_4~(2-)(7.704.53)mug/m~3,; Cl~-(6.173.85)mug/m~3, Na~+(4.592.28)mug/m~3, NO_3~-(4.24 3.07)mug/m~3,; NH_4~+(1.531.20)mug/m~3, Ca~(2+)(0.951.47)mug/m~3,; Mg~(2+)(0.590.30)mug/m~3 and K~+(0.310.17)mug/m~3. The sea water was; identified as the dominant source for Cl~-, Na~+ and Mg~(2+). Besides; the contribution from the sea salt, the K~+ had other sources, such as; coal and biomass burning, and mineral etc. 60% Ca~(2+) came from the; local construction dust, while 77% SO_4~(2-) originated from coal and; biomass burning. The NO_3~- dominantly sourced from the vehicle exhaust,; coal and biomass burning, while NH_4~+ totally originated from the; second inorganic aerosol and biomass burning. By combining our results; with previous findings, in spring, the concentrations of Cl~-, Na~+ and; Mg~(2+) in TSP increased gradually from the Northeast of China to the; Northwest Pacific Ocean; on the contrary, the Ca~(2+), K~+, NH_4~+,; SO_4~(2-) and NO_3~- in TSP decreased gradually. The spatial; characteristics of different water-soluble ions in TSP were associated; with their long-range transport in the marine boundary layer.国家973计划项目; 国家自然科学基金项目台湾海峡联合基金资助项目; 东华理工大学校科技创新团队科研启动基金项目; 江西省教育厅科技项目;; 东华理工大学博士科研启动基金项
