Abstract: Using information in-the-world as external memory may be a low-cost alternative to internal memory: storage is free, and retrieval is often quick (involving a saccade) and reliable.However, when the cost of accessing external information increases, in-the-head storage and retrieval may become the least-cost solution.We employ the rational analysis framework (Anderson, 1990) to study the effect of varying the cost of information access on interactive behavior.Increasing the cost of information access induced a switch from information in-the-world (the perceptualmotor strategy) to information in-the-head (the memory strategy).Given the effort and unreliability of internal storage, the threshold for switching from an in-the-world to an in-the-head strategy is surprisingly low.memory item.If C is the memory search cost, then expected utility E = PG -C.
