title: Word knowledge influences character perception.
abstract: In two experiments, we examined whether context information can affect the activity of the nodes at the character level. Chinese readers viewed two Chinese characters; one was intact, but the other (the target) was embedded in a rectangle of visual noise and increased in visibility over time. The two characters constituted a word in one condition but did not in the other condition. The task was to press a button to indicate whether the character in the noise was at the top or bottom of the rectangle. (They did not have to identify the character.) Response times were faster in the word condition than in the nonword condition. Because the "wordness" of the stimulus was logically irrelevant to judging the location of the target character, the data indicate that processing at the word level can feed back to fairly low-level judgments, such as where a character is.
