摘要
三项实验探讨了阅读中课文语境对单词识别的影响。实验一和二分别在两种课文呈现速度条件下,观察课文语境对词汇决策任务的影响,发现仅在较快的呈现速度(每隔150ms呈现一字)和目标词在前文语境中的可预测性为90％以上时,才产生课文语境的促进效应和抑制效应,并表现出抑制优势模式。实验三采用较自然的校对作业考察这种效应,结果显示在目标词高可预测(在前后文中的可预测性为83％以上)时,存在较显著的整体语境效应,并仍表现出抑制优势模式。据此,本文讨论了课文语境中的单词识别过程和语境对它的作用机制。
The text contextual effect on Chinese word recognition in reading is exa-
mined in three experiments. In experiment 1 and 2, the influence of text con-
text on lexical decision task is studied with two different presentation speeds
of the text, which indicates that only under highspeed (150ms per character)
presentation and high predictability(above 90%) condition, there exists the fa-
cilitation and inhibition effects of the context, showing an inhibition dominant
pattern. A further exploration of this effect is done with proofreading task
in experiment 3, which is more similar to the natural reading situation. A
significant contextual effect is found in high constraint context, also showing
an inhibition dominant pattern. According to these results, the processes of
word recognition in the text and the machanism of the text context effect
are discussed.
