🎉🎓 Big congrats to @josefinehebisch.bsky.social who successfully defended her thesis "Through the Eye of the Beholder: Pupil-Linked Arousal in Memory Formation and Decision-Making" last week and earned her PhD "summa cum laude"! So proud of your accomplishments!

Sounds played during the presentation of images had a positive influence on image recall immediately after encoding. This positive effect could only be observed for images as this onset timing was not applied in the words task due to the auditory nature of word stimuli. 6/10

We replicated earlier correlational relationships. Higher task-evoked pupil-linked arousal during encoding of words predicted better recall one day later. Pupil responses during recognition decisions correlated with the old/new bias for both recognition decisions about words and images. 4/10

It fits the behavioral data better than a range of alternatives, and reproduces a number of behavioral and neural signatures, including the concurrently measured dynamics of the encoding of contrast samples in visual cortex.

Our model combines sensory adaptation, leaky accumulation with feed-forward inhibition, and an asymmetric readout of the DVs in confidence formation.

We next used single-trial regression to predict confidence from the winning and losing DVs, controlling for evidence strength. Both DVs made a significant, unique contribution to confidence. However, in contrast to standard models, the magnitude of the winning DV was stronger.

Despite the independent inputs, we found intrinsic negative correlations between the two DVs within trials, a signature of inhibition between the sensory-motor pathways supporting the two alternative choices. The strength of this correlation on each trial predicted confidence.

We tracked the competition between neural decision variables (DVs) in the human frontal cortex, combining a novel task with atlas-based multivariate decoding of source-level MEG data to track two neural DVs for alternative choices in left and right premotor/motor cortex (PMd/M1).
