abstract = {Interval timing performance in cognitive decline is
typically characterized by decreased accuracy, precision, or
both. One explanation for this decreased performance is a
larger clock time variability. However, memory deficiencies
associated with cognitive decline might also affect temporal
performance in two alternative ways: First, memory
deficiencies could lead to reduced encoding of just
perceived durations, and thus a stronger reliance on the
memory traces of previous experiences (the 'prior'),
yielding less precise reproductions of the most current
experiences. Second, memory deficiencies could hamper the
storage of perceived intervals, thus resulting in less
influence of the prior. Here, we present data of 15 patients
with amnestic Mild Cognitive Impairment (aMCI) and 44
healthy, aged controls, the latter split in two groups based
on memory performance. All participants were tested on a
temporal production task to assess clock time variability
and a multi-duration reproduction task to assess the
influence of memory traces reflecting current and previous
experiences. Patients with aMCI showed the strongest
regression towards the mean in a multi-duration reproduction
task, followed by low-performing healthy controls and
high-performing healthy controls, respectively. As no
difference was observed between the groups in terms of clock
time variability, and clock variability did not
statistically contribute to the observed regression, this
increased central tendency effect was not attributable to
clock noise. We therefore, in line with the first
explanation, conclude that memory deficiencies result in a
stronger (relative) reliance on the prior.},
