字彙知識在字彙觸接歷程中之作用

THE ROLE OF LEXICAL KNOWLEDGE IN A MODIFIED STROOP TASK

本研究以字彙判斷之作業方式，探討刺激材料不同時，受試者之反應策略是否會隨之而異。實驗一之材料是由「真字」與「非字」所組成，而當目標項和干擾項均為合法的「真字」時，並控制其間的字形相似性與字音相同性；實驗二則呈現由「真字」與「假字」所組成之實驗材料。結果發現，刺激材料之不同確實會影響受試者所採取之反應策略，當刺激材料是由「真字」與「非字」所組成之時，特殊字彙知識並不會影響受試者之反應，然而當刺激材料是由「真字」與「假字」所組成時，受試者則會根據所觸接到的特殊字彙知識做出反應，至於字形和字音等特殊字彙知識的觸接，則是一種平行運作的歷程。

The lexical decision paradigm was used to examine whether the response strategy the subjects used in making judgment would be affected by the embedding context of the stimulus characters in the experiment. The stimuli used in experiment 1 were mixed with characters and noncharacters, while presentation of characters in experiment 2 were mixed with characters and pseudocharacters. The results showed that subjects changed their response strategy when the context of the character presentation in the experiment was changed. The role of both graphemic and phonemic information in lexical decision was also examined in this work.
