<b class="ContentPasted0">Abstract:</b> Perceptual decisions are accompanied by feelings of confidence that reflect the likelihood that the decision was correct. Computational frameworks describe these feelings of confidence as an evaluation of the evidence
used for making the perceptual decision. However, perceptual decisions themselves are described by a process of evidence accumulation that evolves over time. By examining this evidence accumulation process in relation to both perception and confidence, we
show a partial dissociation in the evidence used for perceptual decisions and confidence evaluations. In particular, confidence can rely on evidence that continues to accumulate after perceptual decision commitment. We isolate separable neural signatures of
confidence that are present both during perceptual evidence accumulation and after perceptual decision commitment. This ongoing evidence accumulation contributes to confidence even for perceptual decisions based on brief stimulus presentations, and largely
rely on ongoing perceptual processes that can be interrupted by backward masking independently of the perceptual decision processes. Together, these findings highlight the dynamic processes involved in forming feelings of confidence, which are closely related,
but distinguishable from, the processes involved in making perceptual decisions.

<div class="ContentPasted0"><b class="ContentPasted0">Bio:</b> Tarryn is a postdoctoral researcher working with Marios Philiastides at the University of Glasgow (UK). Prior to this she worked as a postdoc with Pascal Mamassian and Valentin Wyart (France) after
completing her PhD at UNSW Sydney with Colin Clifford. Her research examines perceptual decision-making, and how we feel confident in our decisions. Beyond merely monitoring, confidence could be used for learning in the absence of explicit feedback, or even
to control decision-making processes online. Using a combination of psychophysics, computational modelling, EEG, and fMRI, Tarryn’s research teases apart the processes for decisions and confidence to examine the mechanisms involved in the influence of confidence
on perceptual decisions.</div>
