World models are a highly speculative topic in AI as well as in cognitive science. I’m excited to share my manuscript on investigating internal world models using imagination networks in humans and LLMs! 🧵1/n

Internal World Models as Imagination Networks in Cognitive Agents

What is the computational objective of imagination? While classical interpretations suggest imagination is useful for maximizing rewards, recent findings challenge this view. In this study, we propose...

Do you ever compute d' in detection tasks? Because of unequal variance, d' is biased in such tasks and you can't fix the bias without confidence ratings. In this preprint led by Kiyo Miyoshi and @hakwan.bsky.social, we show how to use RT instead of confidence to fix the d'.

Want to exclude a study from a review or meta-analysis because you don't like it but don't have an objective reason for the exclusion? Fear not. Here's the paper you need to cite.

New lab preprint led by Medha Shekhar in collaboration with @axc.bsky.social. We investigate what drives confidence in decisions of real-world complexity (perception and memory questions about short videos). It turns out confidence is influenced by so many factors!

1/3) This may be a very important paper, it suggests that there are no prediction error encoding neurons in sensory areas of cortex:

www.biorxiv.org/content/10.1...

I personally am a big fan of the idea that cortical regions (allo and neo) are doing sequence prediction.

But...

🧠📈 🧪

Sensory responses of visual cortical neurons are not prediction errors

Predictive coding is theorized to be a ubiquitous cortical process to explain sensory responses. It asserts that the brain continuously predicts sensory information and imposes those predictions on lo...

What does our conscious perception of this set of berries consist of? If you heard about Ensemble perception, you could say: “It’s too much info for our poor attention/working memory systems, so instead of storing all the individual features, people just represent the average and variability.” 1/5

I'd love for mind uploading to become a reality much sooner. I just don't think that anything under 100 years is realistic. But of course, such long-term predictions are incredibly difficult. I think that on Bluesky, most people would think that 200 is too optimistic!

My short take on when we'd be able to do mind uploading. My speculation: between 100 and 200 years from now. theconversation.com/can-you-uplo...

Proud to play a small role in this null result - from the excellent and thorough @carolinephelps.bsky.social. No effect of chronic or acute pain on working memory in the Sternberg task.

Caroline Phelps @carolinephelps.bsky.social · May 22

Is the pain of null data taking up slots in your working memory? Or shifting you over optimum arousal on the Yerkes Dodson curve?

Not for me! I've externalized it to this lovely preprint!

Plus, read on for why it might not be the pain that causes deficits in your working memory... 🧵

Great to see our research, led by @johannakuci.bsky.social, covered in The Transmitter. One of the more surprising findings to have come out of the lab.

The Transmitter @thetransmitter.bsky.social · Apr 18

Neuroscientists should embrace variability in neuroimaging studies, according to researchers who showed that decision-making is associated with subtypes of brain activity.

By @claudia-lopez.bsky.social

#neuroskyence

www.thetransmitter.org/behavior/dur...

During decision-making, brain shows multiple distinct subtypes of activity

Person-to-person variability in brain activity might represent meaningful differences in cognitive processes, rather than random noise.
