Ss were given extensive practice in scanning through lists of printed symbols for particular targets. By the thirteenth day, they scanned as rapidly when searching for any of 10 different targets as when searching for any of five, or for one target alone. These results are compatible with the assumption that many subsystems for processing visual information can operate in parallel, at least in situations where a high degree of accuracy is not required.
