In thinking about the evolution of memory together with all its possible aspects, it is helpful to consider what would happen if memories failed to fade. Forgetting clearly aids orientation in time, since old memories weaken and the new tend to stand out, providing clues for inferring duration. Without forgetting, adaptive ability would suffer, for example, learned behavior that might have been correct a decade ago may no longer be. Cases are recorded of people who by ordinary standards forgot so little that their everyday activities were full of confusion. Thus forgetting seems to serve that survival of the individual and the species. Another line of thought assumes a memory storage system of limited capacity that provides adaptive flexibility specifically through forgetting. In this view, continual adjustments are made between learning or memory storage input and forgetting output. Indeed, there is evidence that the rate at which individuals forgets is directly related to how much they have learned. Such data offer gross support of contemporary models of memory that assume an inputoutput balance. |
