That experiences influence subsequent behavior is
evidence of an obvious but nevertheless remarkable activity called remembering.
Learning could not occur without the function popularly named memory. Constant
practice has such as effect on memory as to lead to skillful performance on the
piano, to recitation of a poem, and even to reading and understanding these
words. So-called intelligent behavior demands memory, remembering being a
primary requirement for reasoning. The ability to solve any problem or even to
recognize that a problem exists depends on memory. Typically, the decision to
cross a street is based on remembering many earlier experiences.
Practice (or review) tends to build and maintain memory for a task or for
any learned material. Over a period of no practice what has been learned tends
to be forgotten, and the adaptive consequences may not seem obvious. Yet,
dramatic instances of sudden forgetting can seem to be adaptive. In this sense,
the ability to forget can be interpreted to have survived through a process of
natural selection in animals. Indeed, when one's memory of an emotionally
painful experience lead to serious anxiety, forgetting may produce relief.
Nevertheless, an evolutionary interpretation might make it difficult to
understand how the commonly gradual process of forgetting survived natural
selection. 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. This 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 forget is
directly related to how much they have learned. Such data offers gross support
of contemporary models of memory that assume an input-output balance.
