To wrap up #SPIN2026 in a playful way, I prepared a psycholinguistics-related blind test for the last evening event. The goal was to identify both the song and type of signal processing that was applied to it. Let's see if you can solve these ⬇️
That's it, #SPIN2026 is over, thank you to all attendees for two great days of thought-provoking talks, amazing poster sessions... and actual speech-in-noise demo during coffee breaks!

With some trepidation, I'm putting this out into the world:
gershmanlab.com/textbook.html
It's a textbook called Computational Foundations of Cognitive Neuroscience, which I wrote for my class.
My hope is that this will be a living document, continuously improved as I get feedback.

How about in this case?
Surprisingly, most people *predominantly see 180° motion*, while 360° motion is hardly, if ever, perceived – even though the rings move in the same way as above!

Regarding the "you don't really understand how a car works unless you can build one" debate, it's interesting to realize that neuroscientists are far from understanding how brains work, but that it takes only two unskilled people to create a new one from scratch.

Last year I decided to conduct a replication study of a milestone study in psychoacoustics, as I needed an example to showcase the capabilities of the toolbox we develop. I turned it into an small internship project.
