Anxiety and the visual brain: (Neuro-)cognitive mechanisms underlyingpredictable and unpredictable threat processing

Matthias J. Wieser, Erasmus University Rotterdam, Netherlands

Sensory facilitation of cues that predict harm is a useful mechanism for the efficient detection of threat
in the environment. In this talk, I report studies employing steady-state visual evoked potentials
(ssVEPs), in which we examined sensory gain in early visual cortex in response to different sources of
threat. A key focus will be on the differentiation between predictable and unpredictable threat.
Furthermore, I will report recent data-driven approaches in which we aim to combine lab-based
assessment of threat processing with measurements outside of the lab (ecological momentary
assessment) or multi-paradigm assessments of different neurocognitive processes in larger samples to
develop profiles of anxious psychopathology.
