abstract = {Predicting upcoming events using past observations is a
crucial component of an efficient allocation of attentional
resources. Therefore, the deployment of attention is
sensitive to different types of cues predicting upcoming
events. Here we investigated probabilistic inference
abilities in spatial and feature-based attentional, as well
as in motor-intentional subsystems, focusing specifically on
the age-related changes in these abilities. In two
behavioral experiments, younger and older adults (20 younger
and 20 older adults for each experiment) performed three
versions of a cueing paradigm, where spatial, feature, or
motor cues predicted the location, color, or motor response
of a target stimulus. The percentage of cue validity (i.e.,
the probability of the cue being valid) changed over time,
thereby creating a volatile environment. A Bayesian
hierarchical model was used to estimate trial-wise beliefs
concerning the cue validity from reaction times and to
derive a subject-specific belief updating parameter ω in
each task version. We also manipulated task difficulty:
participants performed an easier version of the task in
Experiment 1 and a more difficult version in Experiment 2.
Results from Experiment 1 suggested a preserved ability of
older adults to use the three different cues to generate
predictions. However, the increased task demands of
Experiment 2 uncovered a difference in belief updating
between the two age groups, indicating moderate evidence for
a reduction of the ability to update predictions with motor
intention cues in older adults. These results point at a
distinction of attentional and motor-intentional subsystems,
with age-related differences tackling especially the
motor-intentional subsystem},
