If recognition implies a
contribution from past
experience, some enduring
repository of such experience
must exist in the brain at the
time of the present perception.
Psychologists refer to such a
representation of past
experience as a memory trace
(or, simply, a trace).
Presumably every prior
perception (as well as every
thought, feeling, or other
conscious mental event) has
left behind a memory trace.
Psychologists agree, and
indeed logic dictates, that
access to the appropriate
memory trace following
perception of a particular
shape is based upon the
similarity of the trace to that
percept. Once a perception
occurs, it is as if a search is
conducted, obviously at an
incredibly rapid rate, through
all the traces stored in
memory, or perhaps through
all the traces classified in
some particular category. The
search ends when a trace is
found that is similar to the
present perception.
Recognition is based on the
unconscious acceptance of the
match between trace and
percept.
