title: The effect of extraneous elements surrounding a Kanizsa-like illusory-figure pattern.
abstract: A display in which a Kanizsa-like illusory-figure pattern of three notched circles was accompanied by several other notched circles was found to be relatively ineffective, thus confirming an important, but previously untested, suggestion. This ineffectiveness may have been due to a strengthened tendency of the visual system perceptually to 'explain' each edge of each of the three critical notches as belonging to one of the partial circles themselves, thus tending to preclude any other (ie illusory) 'explanation' of those edges.
