There is general agreement that visual attention is selective. There is less agreement about the role played by spatial location in visual selection. Recent theories (e.g., feature integration and object identification) suggest a special role for spatial location. The present study tested a prediction derived from the hypothesis that there is a unique role for spatial location in the recognition of visual stimuli. The procedure involved priming locations for specific colors. Subjects were presented a colored prime at one of four possible locations. After an SOA of 150 msec, a colored target letter appeared at the primed location. The target either matched or mismatched the prime in color. Subjects pressed a key to identify the target letter. The results indicated that response latency was not facilitated when targets matched their primes in color. Thus, no evidence was obtained in favor of stimulus driven color-at-location priming.
