abstract = {For memory retrieval, pattern completion is a crucial
process that restores memories from partial or degraded
cues. Neurocognitive aging models suggest that the aged
memory system is biased toward pattern completion, resulting
in a behavioral preference for retrieval over encoding of
memories. Here, we built on our previously developed
behavioral recognition memory paradigm-the Memory Image
Completion (MIC) task-a task to specifically target pattern
completion. First, we used the original design with
concurrent eye-tracking in order to rule out perceptual
confounds that could interact with recognition performance.
Second, we developed parallel versions of the task to
accommodate test settings in clinical environments or
longitudinal studies. The results show that older adults
have a deficit in pattern completion ability with a
concurrent bias toward pattern completion. Importantly,
eye-tracking data during encoding could not account for
age-related performance differences. At retrieval, spatial
viewing patterns for both age groups were more driven by
stimulus identity than by response choice, but compared to
young adults, older adults' fixation patterns overlapped
more between stimuli that they (wrongly) thought had the
same identity. This supports the observation that older
adults choose responses perceived as similar to a learned
stimulus, indicating a bias toward pattern completion.
Additionally, two shorter versions of the task yielded
comparable results, and no general learning effects were
observed for repeated testing. Together, we present evidence
that the MIC is a reliable behavioral task that targets
pattern completion, that is easily and repeatedly
applicable, and that is made freely available online.},
