abstract = {Objective: In subjects with mild cognitive impairment
(MCI), interference during memory consolidation may further
degrade subsequent recall of newly learned information. We
investigated whether spatial and object memory are
differentially susceptible to interference.Method:
Thirty-nine healthy young subjects, 39 healthy older
subjects, and 12 subjects suffering from MCI encoded objects
and their spatial position on a 4-by-5 grid. Encoding was
followed by either: (i) a pause; (ii) an interference task
immediately following encoding; or (iii) an interference
task following encoding after a 6-min delay. Type of
interference (no, early, delayed) was applied in different
sessions and order was counterbalanced. Twelve minutes after
encoding, subjects saw objects previously presented or new
ones. Subjects indicated whether they recognized the object,
and if so, the objects’ position during encoding.Results:
Interference during consolidation provoked a negative effect
on spatial memory in young more than older controls. In MCI,
object but not spatial memory was affected by interference.
Furthermore, a shift from fine- to coarse-grained spatial
representation was observed in MCI. No differential effect
of early vs. late interference (EI vs. LI) in either of the
groups was detected.Conclusions: Data show that
consolidation in healthy aging and MCI differs from
consolidation in young controls. Data suggest differential
processes underlying object and spatial memory and that
these are differentially affected by aging and MCI.},
