Stroop-like task. Am Jrl of Psych, 106(3): 383-405.
Abstract
Three experiments showed that the pattern of interference of single-modality
Stroop tests also exists cross-modally. Distractors and targets were either
pictures or auditory words. In a naming task (Experiment 1), word distractors
from the same semantic category as picture targets interfered with picture
naming more than did semantically unrelated distractors; the semantic
category of picture distractors did not differentially affect word naming.
In a categorization task (Experiment 2), this Stroop-like effect was reversed:
Picture distractors from the same semantic cateogry as word targets interfered
less with word categorization than picture distractors that were semantically
unrelated; the semantic category of word distractors did not differentially
affect picture categorization. Experiment 3 replicated these effects when
each subject performed both tasks; the task; naming or categorizing, determined
the pattern of interference between pictures and auditory words. The results
thus support the existence of a semantic component of a cross-modal Stroop-like
effect.
