Abstract:
A rich body of data exists showing that recollection of
specific information contributes to recognition memory. We present
a model, based largely on known features of hippocampal anatomy and
physiology, that accounts for both the high-threshold nature of
this recollection process (i.e., the fact that only studied items
are recollected, although nonstudied items sometimes trigger
recollection of similar studied items), and the fact that
increasing interference leads to less recollection but apparently
does not compromise the quality of recollection (i.e., the extent
to which recollection veridically reflects events that occurred at
study). Both of these properties of recollection pose problems for
existing computational and mathematical models.
