A time-course contingency is a dependency between processing events during object recognition in which information processed early influences the efficiency of subsequent processing. Nine experiments provided evidence for 2 distinct types of contingencies with different time courses. Common feature primes and targets were presented successively and briefly in the same extrafoveal position and were masked (integration priming). When total stimulus duration was under 150 ms, structurally related primes facilitated identification more than less related primes—a structural contingency. When duration was above 300 ms, primes that attracted attention to the object as a whole facilitated identification and structural relatedness had little or no effect—a contingency involving object-based attention. The results are relevant to models of object recognition and a proposed progression of processes underlying scene perception.
