Abstract
It is widely assumed that the separable features of visual objects, such as their colors and shapes, require attention to be integrated. However, the evidence in favor of this claim comes from experiments in which the colors and shapes of objects would have to be integrated and then also subjected to an arbitrary, instruction-based, stimulus-response (S-R) translation in order to have an observable effect. This raises the possibility that attention is not required for feature integration, per se, but is only required when color-shape conjunctions must undergo an arbitrary S-R translation. The present study conducted a more specific test and found strong evidence in favor of feature integration in the absence of attention. The implications of these results are discussed.
