New #OpenAccess article published in JASA-EL @AcousticalSocietyofAmerica! We used a new technique to explore how listeners segment continuous speech sounds into words. A thread and a demo ⬇️

How does confidence compare to explicit feedback in learning?
We explore this in a new pre-print!

We use simultaneous EEG-fMRI to localise BOLD related to single-trial representations of confidence and explicit feedback value, and relate this to how participants learn to improve in a perceptual decision-making task.
@shriramk @zabbeer @erinnacland @PeerCommunityIn @academicchatter @alexh If a researcher has received funds from a government (e.g., a research grant), citizens have in fact invested in the research and its outputs.
They deserve open access to the research.
There are many stakeholders in this discussion.
The current paywall model is borked, while creating alluring incentives for indentured service.
Interesting preprint on the perspective of early career researchers: https://www.biorxiv.org/content/10.1101/2022.12.06.519378v1
Two quotes:
“constant pressure to write mediocre papers that are flawed and unread, advancing a meaningless metric in pursuit of individual benefit.”
“My data has been extensively doctored/falsified by my supervisor in successful grant applications. This was discussed with senior colleagues who agreed it was major issue but are reluctant to act due to direct and indirect reliance on my supervisor.“
Elsevier appears to be collecting and monetizing our personal data, sometimes without our consent. The data they collect can be used to "extrapolate core working hours, vacation times, and other patterns of a person’s life."
What can we do?
Over 20,000 researchers are refusing to publish, review, or edit for Elsevier. You can also ask them to delete your "non-integral" personal data: https://www.elsevier.com/legal/privacy-policy/data-request

There has been some discussion of the binding problem on twitter. Some people seem to think that the problem is irrevocably tarred with the brush of... Cartesian Theatrics.
But it's clear that we are not conscious of every single process in the brain & body. Percepts and concepts enter and leave the 'stage' of awareness.
Instead of positing a homunculus, perhaps we can view the brain/body as both the play and the audience?

This statement is from 1994. Nevertheless, more often than not it remains true with how papers are written today. i.e., if it doesn't fit the story, don't include it.
"Articles that discuss the hypothesized role of DA in reinforcement rarely, if ever, cite articles showing that accumbens DA is involved in responsiveness to stress."

I just finished Stuart Ritchie's jaw-dropping book "Science Fictions" which exposes the deleterious effects of fraud, bias, negligence and hype on the constitution of scientific knowledge. Of course this is a a deplorable but all-too-familiar observation, however the book brings a new level of detail. (1/3)

This is not just a party trick. We can use nested cognition to better understand metacognition. For example, we show confidence in this context must rely on a fine-grained representation of the perceptual decision-evidence, compared to discrete bins.
Confidence was better than predicted if we assumed all the variability disrupting metacognition would be passed on to the next re-evaluation: relative performance could improve from one re-evaluation to the next.
A toot-summary of our recent article!
We often use our confidence to gauge the reliability of our perception.
But what about the confidence... in our confidence?
Sometimes, we can be certain we are uncertain.
With Samuel Recht, Ljubica Jovanovic, and Pascal Mamassian, we had fun testing the limits of meta-metacognition in a classic visual task.
We found surprising accuracy of confidence up to the fourth order (confidence in confidence in confidence, or meta-meta-meta-cognition).
