[单项选择]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 an effect on memory as to lead to skilful 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 be seen 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 leads 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 in-put-output balance.The author’s main purpose in writing this passage is to ______.
A. interpret the function of forgetting
B. illustrate the process of adapting
C. explain the performance of memory
D. emphasize the importance of learning
