0 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:
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.
The distractor's illusory jump to the left is filled in because it is the motion that must have occurred, assuming the stability of the target and the world.
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.
