内容摘要

本文基于董燕萍双语心理词典的共享(分布式)非对称模型探讨核心概念共享词的表征质量对其在翻译中的词汇提取的影响。本研究为实证研究,共包含两个实验。实验一利用反应时实验测试核心概念共享词在受试心理词库中的表征质量,并根据反应时实验结果中的正确率和正确选项的平均反应时对受试进行筛选,筛选后的60名受试分为高水平和低水平两组。实验二为笔译测试,主要考察高低水平的受试对核心概念共享词在翻译中的提取能力。实验所得发现主要有以下几点:一、本研究通过实验发现,核心概念共享词的表征质量对相应词的词汇提取有积极的促进作用,此作用主要体现在以下几方面:首先,词频效应是本研究所发现的最为显著的效应之一,该效应在词汇提取中具体表现为核心概念共享词组中的高频词提取正确率最高,而低频词的提取正确率远远低于高频词。于表征的角度而言,高频词与共享概念的连接强度要高于低频词,因而实现了高频词提取时更高的正确率。而高频词的这种高质量表征对其提取的积极促进作用在低频词中就无明显体现。其次,词汇的高表象值效应也是本研究中核心概念共享词较为明显的一个特征。高低水平的受试在名词核心概念共享词组的应用提取上都优于在动词和形容词的提取表现。由于有前人实验证明名词比动词和形容词有较高的表象值,因此,反映在表征结构上,高表象值的词汇能够起到更大的概念调节作用,从而对提取有较大的帮助作用。而核心概念共享词中的低表象值因其在表征网络中与共享概念的连接强度较弱便无法实现十分准确的应用提取。二、核心概念共享词的表征质量对词汇提取的积极促进作用有其动态发展的特点。这一发现主要是基于对高低水平受试在不同词类的表现上的分析总结。首先,高低频词在高水平受试中的词汇提取表现差异要大于在低水平受试中的差异,即随着二语学习者语言水平的提高,他们对高频词的掌握和应用要远远超过低水平者,即低水平学习者由于其词汇表征网络的薄弱,即使是在高频词的提取上也显示不出太大的优势。其次,与词频效应相反,词汇表象值效应反而会随着二语学习者水平的提高而减弱,这说明低水平学习者由于其词汇表征网络的不完善而在词汇提取中更加依赖概念的调节作用,而高水平这由于其表征网络资源的更加丰富而不仅仅依赖概念调节来获取词汇。因此,词汇表象值效应的减弱也就意味着二语词汇表征网络发展趋于平衡和逐渐完善。
