Alternative approaches maintain that cognitive resources are in some sense protected or conserved in that greater amounts of perceptual-motor effort will be expended to conserve lesser amounts of cognitive effort. One alternative, the minimum memory hypothesis (MMH), holds that people favor strategies that minimize the use of memory. SCH is compared with MMH across 3 experiments and with predictions of an Ideal Performer Model that uses ACT-R’s memory system in a reinforcement learning approach that maximizes expected utility by minimizing time. Model and data support the SCH view of resource allocation; at the under 1000-millisecond level of analysis, mixtures of cognitive and perceptual-motor resources are adjusted based on their cost-benefit tradeoffs for interactive behavior.</style></abstract><notes><style face="normal" font="default" size="100%">Office of Naval Research ONR# N000140310046, as well as the Air Force Office of Scientific Research AFOSR #F49620-03-1-0143</style></notes><urls><pdf-urls><url><style face="normal" font="default" size="100%">internal-pdf://GSFS06_PsycRvw-1191476480/GSFS06_PsycRvw.pdf</style></url></pdf-urls></urls><research-notes><style face="normal" font="default" size="100%">AFOSR &amp; ONR</style></research-notes></record></records></xml>
