Can we predict who is going to experience hallucinations? I think we can, in a new theory paper with @tesvlee.bsky.social and Giovanni Sala

"A novel model of divergent predictive perception"

Now published in Neuroscience of Consciousness

A novel model of divergent predictive perception
Abstract. Predictive processing theories state that our subjective experience of reality is shaped by a balance of expectations based on previous knowledge abou

Now available in its entirety, you can read Ruth Rosenholtz's Behavioral & Brain Sciences critique of attention as an explanation tool in vision science and our reaction to her piece.

Hayward Godwin, Michael Hout, and I have written a response to a provocative piece by Ruth Rosenholtz in Behavioral & Brain Sciences where she argues for an abandonment of the concept of “attention” as an explanatory tool.

Welcome to the world of Ganzflicker... in comic form!?

Comic by the fabulous [email protected], Instagram: @Mr.dog.art
A MassArt initiative led by @hudrewthis.bsky.social

Hallucinations are often feared and unwanted... But what if we could induce them, so we can better understand them?
Narration: Hallucinations are complex phenomena occurring involuntarily to individuals with a mental disorder. They are often feared and unwanted. Narration: But what if they can be controlled? What if we could intentionally induce them in a secure way, so we can better understand them? Narration: In order for an experimentally induced hallucination to form, the mind must be presented with something specific that is visually very different from what it is accustomed to seeing. Narration: Sensory deprivation: The lack of stimuli (specifically visual). Participants engaging in this method of hallucination induction can be completely blindfolded or left in a pitch black environment. Either way, their mind must not be exposed to light. Narration: Ganzfeld: A uniformly colored, luminary visual field (e.g. a clear blue sky or a singular color on a screen). Exposure to ganzfeld can induce slight visual hallucinations. (Figure laying on the grass, facing a clear blue sky.) Narration: Sensory deprivation can be an unreliable method for the intention of experiencing induced hallucinations. Visuals aren’t always guaranteed, and it can take hours or even days for imagery to start showing up. (Figure sitting on the ground, blindfolded. Cobwebs are on the figure, signifying a long time has passed. A little spider is next to the figure.) Narration: Ganzfeld is also not very reliable. Though most individuals experience visuals, they are not very complex. Most experience colors and simple geometric patterns after a while. (Side view of a head, a cloud forming from their head that contains simple geometric shapes.) Narration: But is there a way to induce complex and vivid hallucinations almost immediately and comfortably? There sure is! (Two figures, shoulders up, next to each other. Exclamation marks next to one, and a question mark next to the other. They are both looking at the text bubble.)

With this new pub arguing that aphantasia is NOT an episodic memory condition, I agree that aphantasia must be defined, first and foremost, by a lack of imagery. However, aphantasia reduces the vividness of episodic memories in predictable ways. Here's another idea... 1/8

Good post with two takeaways for me: 1) we also make mistakes as reviewers (I'm sure I made my share - sorry to those who were wronged) and 2) we need to appreciate papers without data more - a good theory doesn't need data to be good

Ganzflicker gets a lot of hate, but look- I know it's cheesy. But the name is probably why it's so popular, and got me my job. People will always make fun of things that are different... but if you just go by what everyone else thinks, you'll never stand out 🙃

If you can see the balance of how much an author collaborates vs. had the primary/senior position, it can actually highlight those collabs, or reveal a potentially problematic imbalance. I'm happy to hijack the metric to get insights I think are important. We don't have to use it as Google intended.

I've been playing around with this and it's actually kinda neat - it separates an author's h-index into 1st, 2nd, other, and last authorship positions. Perhaps this could encourage a more even spread (& ignore the final weighted metric proposed). What do you think?
Google Scholar tool gives extra credit to first and last authors
Researchers welcome the initiative, but say it doesn’t go far enough to capture the nuance of researcher productivity and impact.
