The article discusses how preexisting beliefs shape learning from feedback and influence the processing of news, using eye-tracking data to show pupillary responses that occur before a conscious decision. It highlights how accuracy in updating beliefs is affected by whether rewards align with those beliefs and how confidence levels modulate openness to change.

This topic is of interest to psychology readers because it links cognitive learning mechanisms with belief formation and misinformation, illustrating how internal states and physiological signals can shape information processing in everyday life.

New popscience piece on why pupil size changes are cool:

Included: an assignment that lets you measure pupil size that I developed for teaching. In my classes, this replicates Hess & Polt's 1964 effort finding without an eyetracker. Feel free to use it!

Thanks a lot to Christian Jarrett of Psyche.co for all the work on editing.

I did a #pupillometry study! And I got a result!

Leaving labels vague for now (come see my posters at AMLaP next month for details!), but lookit! Pupils are larger when Condition is Hard than when it is Easy!

Do you care about pupillometry? We need to rewrite its history in neurosciences and psychology. Now @TrendsNeuro

A rediscovery of the forgotten early wave of pupillometry research – effort, covert attention, imagery all made visible by 1900 in a fascinating literature. https://authors.elsevier.com/a/1jKdtbotq3zQC

New preprint! We observed a nonlinear relationship between pupil dilation and the intensity of transcutaneous auricular #vagus nerve stimulation (#taVNS) in adult humans. We discuss the potential role of stimulation parameterization in using #pupillometry as biomarker of taVNS’s neuromodulatory effects.

I just posted the first wrap-up video in the Pupillometry online course we started this week, with Professor Bruno Laeng answering some questions from learners.

It is not too late to join if you want to learn about #Pupillometry and #EyeTracking. The course runs for six weeks, with a workload of 2-3 hours per week. And it is free!
