“…The issue of capacity is closely related to the issue of independence (Townsend & Wenger, 2004b) and refers to the way in which system performance changes as workload is varied (for discussions, see Townsend & Ashby, 1978;Townsend & Nozawa, 1995;Townsend & Wenger, 2004b;Wenger & Townsend, 2000). For example, if it is assumed that when featural information is augmented by configural information (i.e., if the amount of information to be processed and, thus, the workload are increased) there will be no observable effect on processing efficiency, the perceptual system can be assumed to possess unlimited capacity.…”
