Hi all!👋 This year, my sabbatical will focus on learning more about the brain, esp. neural mechanisms behind social theory of mind & affect. This includes its breakdowns, e.g. psychosis, hallucinations and delusions related to ToM. I'll be posting what I learn along the way. Thanks for connecting! ☺️

"My (female) participants take a positive stance. Women have historically navigated male-dominated constraints, acting compliant in exchange for a man's love. Now they can bypass complex power structures through relatively simple consumption, achieving similar emotional fulfillment".

Is anyone following me an expert on love? I find the possible link between infatuation and psychosis compelling:

Why would someone pay $20k for a robot controlled by a human in a remote location to do things more slowly and clumsily when the median wage for a maid or housekeeper is $33k per year, which is typically spread across 10-20 households?

Amazing opportunity! Please reach out if you are excited to work on the neuroscience of mood/happiness and want to apply. We have so much going on in this space @upenn.edu and it’s “all hands on deck” to meet society’s needs. Here at Penn we’re eager to support & launch the next gen in this space.

What if many psychiatric disorders share the same hidden glitch in how the brain infers reality? In a new volume, Al Powers and I gather experts to examine how disrupted sensory inference across #vision, #touch, #proprioception and #interoception might unify our understanding.

"the frame problem broadly refers to the difficulty of teaching a machine to make smart decisions based on relevant information without having it explicitly consider every irrelevant detail." Is De Sousa (et al)'s suggestion that emotions solve the frame problem not considered useful for AI?
