The present study used event-related potentials (ERPs) to determine the degree to which people can process words while devoting central attention to another task. Experiments 1-4 measured the N400 effect, which is sensitive to the degree of mismatch between a word and the current semantic context. Experiment 5 measured the P3 difference between…

Sensory or input factors can influence the strength of interference in the classic Stroop color-word task. Specifically, in a single-trial computerized version of the Stroop task, when color-word pairs were incongruent, opponent color pairs (e.g., the word BLUE in yellow) showed reduced Stroop interference compared with nonopponent color pairs…

A theory for the visual and cognitive processing, which accounts for slower naming of pictures than reading of words, is introduced. Two experiments assessed the differences distinguishing word reading and picture naming, using 58 undergraduates. The coding of the mind is neither intrinsically linguistic nor imagistic; it is abstract. (TJH)
