Neural and computational analyses further revealed that task effects on preparatory activity over motor cortex, resembling a starting point bias, were smallest on trials with high phasic pupil-linked arousal. (5/6)

Where increased tonic arousal (pupil-linked; trend for drugs) was related to more liberal ('yes') decisions independent of task, increased phasic arousal was uniquely associated with weaker task-related shifts in decision bias. Tonic & phasic arousal thus distinctly shaped decision bias. (4/6)

Here, we aimed to 1) uncover the neural mechanisms by which arousal governs decision bias and 2) causally test if/how tonic arousal affects bias. To do so, we combined correlational measures (pupillometry) & causal manipulations (pharmacology) of arousal with EEG and two bias-inducing tasks. (3/6)
