abstract = {The precise cognitive mechanisms underlying spatial neglect
are not fully understood. Recent studies have provided the
first evidence for aberrant behavioral and
electrophysiological prediction and prediction error
responses in patients with neglect, but also in
right-hemispheric (RH) stroke patients without neglect. For
prediction-dependent attention, as assessed with Posner-type
cueing paradigms with volatile cue-target contingencies,
studies in healthy volunteers point to a crucial role of the
right temporo-parietal junction (rTPJ) – as part of a
network commonly disrupted in neglect. In order to study
altered prediction-dependent attention in patients with RH
damage and neglect, the present study employed a spatial
cueing paradigm with unsignalled changes in the cue’s
predictive value in 26 RH patients, 21 left-hemispheric (LH)
patients, and 33 healthy elderly controls. The inference of
the changing cue’s predictive value was assessed with a
Rescorla-Wagner learning model of response times (RTs) and
participants' ratings. We tested for lesion-side-dependent
relationships between the computational model parameters,
ratings, and neuropsychological performance. Moreover, we
investigated links between the behavioral signatures of
predictive processing and lesion anatomy (lesion location
and disconnection). The results provided no evidence for a
predictive inference deficit, but revealed a correlation
between a hypersensitivity of RTs to inferred predictions
for ipsilesional stimuli and neglect symptoms in RH
patients. Irrespective of symptoms of neglect, the rating of
the cue’s predictive value deviated more from the actual
values in RH patients. RT hypersensitivity for ipsilesional
targets was linked to disconnection within fronto-parietal,
fronto-occipital, and temporo-parietal pathways. These
findings provide novel insights into the role of altered
prediction-dependent processing for neglect as assessed by
different read-outs, highlighting an exaggerated response
adaption to predictions of ipsilesional stimuli.},
