Practicing simple visual casks indices substantial improvement. We investigated whether increased efficiency is accompanied by automaticity and immunity to across-task interference. We found that although practice speeds orientation feature detection, if does not abolish susceptibility to interference from introduction of concurrent central-letter identification, which fakes priority Yet following training with each task observers successfully managed to perform the tasks concurrently The effectiveness of separate training implies that the role of improved intertask coordination in achieving concurrent perfomance was minor. Indeed, even when initial training was concurrent, improvement on the two casks was sequential, and the higher-priority (central) task was learned first. However, antomatic processing was not accomplished either, because increasing the difficulty of the higher-priority task interfered with performance of both tasks. What appears to be orchestrated posttraining performance is actually mainly an emergent property of speeded initial processes rather than either eliminated bottlenecks or improved central executive management.
