Memory versus Perceptual-Motor Tradeoffs in a Blocks World Task

Information stored in the external environment can be considered as a kind of external memory. However, when the cost of information access increases, people would invest more time storing information into working memory and rely less on the external environment. We employ the rational analysis framework by Anderson (1990) to study the effect of varying the cost of information access on interactive behavior. Our results show how the cost of information access could induce a switch from reliance on information on the external environment (perceptual-motor strategy) to that in the human memory system. We found that although memory is a limited resource, there are conditions under which people can use it to optimize performance.
