不同结构文章重复阅读时主题转换效应的眼动研究

选取36名大学生,运用眼动技术,探讨不同结构类型文章在重复阅读时主题转换效应的变化特点。被试阅读的材料有两类:一是段落内部各个句子之间为平行关系(平行材料);一是每段第一个句子为该段落主题句(总分材料)。结果发现,两类材料在第一遍阅读过程中均出现了显著的主题转换效应,但在重复阅读时,主题转换效应消失,说明读者在第一遍阅读时已构建了文章的主题结构表征,并以此来指导后面的阅读。该结果支持共同策略假设理论,说明无论文章中是否存在标记,读者在阅读时都会构建一定完善的主题结构表征。

Topic-Shift Effect During Repeated Reading: An Eye Movement Study on Text of Different Structure

Using eye-movement technique,the present study tried to probe the changing characters of topic-shift effect during repeated reading of articles that have different styles of structure.One kind of the articles has sentences of parallel relationship in each paragraph and the other one has a topic sentence at the beginning of each paragraph.The results show that there is prominent topicshift effect in the initial reading for the two kinds of article but not when rereading the same text in subsequent readings.The absence of topic-shift effect suggests that readers construct a mental representation of the text's topic structure during the initial reading and use the representation to guide subsequent readings,which supports the common-strategy hypothesis.It means that readers will construct a good representation of the topic structure during reading no matter if there are signals in the article.
