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.

Goal selection through the lens of subjective functions:

I welcome any feedback on these preliminary ideas.
Subjective functions
Where do objective functions come from? How do we select what goals to pursue? Human intelligence is adept at synthesizing new objective functions on the fly. How does this work, and can we endow arti...

Mikayla Kelley has an important new paper on why human beings even have a concept of intentional action

The key question: What does this concept do in our lives?

Her answer: Since we can't possibly evaluate all actions, it helps us choose which ones to evaluate

Mikayla Kelley, The Normative Function of Intentional Action - PhilPapers
This essay identifies a normative function of the concept of intentional action. Specifically, I argue that the concept of intentional action functions to focus our evaluative concern on some doings r...

🚨Out now in @cp-trendscognsci.bsky.social 🚨

We explore the use of cognitive theories/models with real-world data for understanding mental health.

We review emerging studies and discuss challenges and opportunities of this approach.

🚨New paper out w/ @gershbrain.bsky.social & @fierycushman.bsky.social from my time @Harvard!

Humans are capable of sophisticated theory of mind, but when do we use it?

We formalize & document a new cognitive shortcut: belief neglect — inferring others' preferences, as if their beliefs are correct🧵

I had an illuminating interaction with a colleague who said that they try to find time to do a few paper reviews per year. It made me realize that different researchers have widely varying expectations about reviewing, probably because there are no public norms.

So pleased and proud to share this work.

I started trying to think clearly about authority punishment in 2018. This new paper with Setayesh Radkani is the first fruit of that labour.

Why so much struggle? See thread.

Punishment, even when intended to teach norms and change minds for the good, may backfire.

Our computational cognitive model explains why!
