||Localisation de l'interference forme/couleur au niveau perceptuel dans une tache de type Stroop avec des stimuli-dessins.
Four studies with 24 19-35 yr old French-speaking adults examined the localization of perceptual form-color interference in a Stroop task with drawings. Results indicate that the time required to name the color of an incongruently colored object, such as a blue banana, was significantly longer than that for a neutral object (a red book). The same effect was found for identifying the color of the ink in which the names of these observed objects were printed. However, there did not appear to be a common semantic component in the interference observed in the 2 tasks. Extended practice on the task with the names of incongruently colored objects did not transfer to the task with the drawings of the same objects. The time to discriminate the colors of 2 drawings of incongruently colored objects was significantly longer than that for 2 drawings of neutral objects, suggesting that a perceptual inhibition occurred for incongruently colored objects (objects for which color was normally an integral part of the stimulus) that created a delay in perceiving the object's color. This contextual interference may be the complementary phenomenon to the object superiority effect. (31 ref) (PsycINFO Database Record (c) 2007 APA, all rights reserved)
