| 释义 | distractor noun[ C ] education, psychology specializeduk /dɪˈstræk.tər/ us /dɪˈstræk.tɚ/ in a test, a wrong answer that is similar to the correct answer, designed to see whether the person being tested can notice the difference: （多项选择试题中的）错误选项，干扰项 The task is built so that one distractor (or incorrect alternative) shows the same object as the correct picture but with a different attribute. 这个任务的形式是通过让一个干扰项（或不正确的选项）显示与正确图片相同的物体，但属性不同。 For each pair of sentences the "incorrect" picture contains either a grammatical distractor (e.g."He is sitting in the tree" vs. "She is sitting in the tree", for a picture of a girl) or a lexical distractor ("He is sitting in the tree" vs. "He is swinging in the tree"). In a study of lexical development in which comprehension of 75 terms was assessed, he contrasted the correct referent with a distractor from the same superordinate category. Infants were coded correct if they pointed to or touched the target image and incorrect if they pointed to or touched the distractor. Later, the pictures are shown again but this time in a random order, interspersed with 20 "distractor" pictures.

Hermans et al. observed that the phonological facilitation of spoken distractor words in picture naming may occur across the languages of bilingual speakers. Other models of the control of spoken word production predict a different time course of the distractor effect. The presentation of the distractor word increases the activation of its corresponding lexical node. In the picture-word interference paradigm, distractor words are thought to activate semantic representations directly (via an input orthographic lexicon). Consider, for example, the effects of distractor words on picture naming latencies. In this task, participants are asked to name a picture and to ignore a superimposed distractor word. The activation reached by the lexical node corresponding to a semantically related distractor ("cat") is higher than that of a semantically unrelated distractor ("cap"). They are also more likely to name the distractor when it is in the language required for production. The visually presented distractor words were bare nouns that were not overtly marked for gender. In the experimental session participants were instructed to name the pictures as quickly as possible, while ignoring the distractor words. The first three trials in each block cor responded to three different warm-up filler pictures that appeared with unrelated distractor words. Negative priming occurs when the prime trial distractor button becomes the critical trial target button. In this task, participants are asked to name a picture that appears more or less coincident with a written or spoken "distractor" word. A semantic relationship between a picture and a distractor word slows picture naming relative to an unrelated condition.
