💡 When making choices—like picking a flat, a job, or a romantic partner—when should we stop looking and commit? Our new study from @rhulpsychology.bsky.social published in
Communications Psychology explores how biased expectations about future options shape our decisions. 🧵👇

Sometimes I think about how from 1935-1975ish, Bell Labs produced an insane amount of revolutionary science and technology, including 11 Nobel Prizes, the transistor, UNIX, C, the laser, the solar cell, information theory, etc. The secret? Provide scientists with ample, steady, no-strings funding.

Meme showing a worker labelled "academic staff" digging a hole in the ground while 10 others look labelled with management titles such as "Director of Human Resources" look on. The caption underneath reads "The only way we can cut costs is to reduce the number of academic staff..."

Our #sEEG study is now published in Nature Communications: rdcu.be/eIkoG! 🧠
Key finding: We discovered neural evidence accumulation for visual perception that's independent of report preparation—recorded from >3000 channels across 3 experiments!

New in @pnas.org: doi.org/10.1073/pnas...

We study how humans explore a 61-state environment with a stochastic region that mimics a “noisy-TV.”

Results: Participants keep exploring the stochastic part even when it’s unhelpful, and novelty-seeking best explains this behavior.

detection d' is generally overestimated, coz we tend to be too lazy to collect the necessary data in order to correct for the unequal variance between target present vs absent distributions. turns out we can do this for free - using reaction times data. so, let's do it~

New preprint out together with @mheilbron.bsky.social

We find that a stimulus' representational magnitude—the L2 norm of its DNN representation—predicts intrinsic memorability not just for images, but for words too.

Representational magnitude as a geometric signature of image and word memorability

What makes some stimuli more memorable than others? While memory varies across individuals, research shows that some items are intrinsically more memorable, a property quantifiable as “memorability”. ...

How does the brain decide? 🧠

Our new @nature.com paper shows that neural activity switches from an 'evidence gathering' to a 'commitment' state at a precise moment we call nTc.

After nTc, new evidence is ignored, revealing a neural marker for the instant when the mind is made up.

🚨We believe this is a major step forward in how we study hippocampus function in healthy humans.

Using novel behavioral tasks, fMRI, RL & RNN modeling, and transcranial ultrasound stimulation (TUS), we demonstrate the causal role of hippocampus in relational structure learning.

This is good on the extraordinary alienation that has now grown up in academia. The gap between the values of lecturers and the universities that employ them are now a huge unbridgeable chasm. One stands for education, the other institutional self-interest. blog.matthewbarnard.phd/a-world-with...

In UK UG ed, students take exactly one subject chosen when 18 yo. One more reason that's not ideal. As a USA undergrad I had to evidence foreign language learning to get my psychology degree. I used my high school French classes but otherwise students in Illinois needed to take a foreign language.

Our new paper is out! When navigating through an environment, how do we combine our general sense of direction with known landmark states? To explore this, @denislan.bsky.social used a task that allowed subjects (or neural networks) to choose either their next action or next state at each step.

PLOS Biology @plosbiology.org · Aug 1

How do humans navigate unfamiliar environments? @denislan.bsky.social @lhuntneuro.bsky.social @summerfieldlab.bsky.social show that humans & deep meta-learning networks combine ‘vector-based’ & ‘transition-based’ strategies for flexible navigation in similar ways @plosbiology.org 🧪 plos.io/45uSwNm

Task design and experimental set-up. Top left: underlying structure of the 8 × 8 grid, unseen by participants. Every state is represented by an image of an object, and these objects and their positions change on every trial. Top right: schematic diagram of the ‘map reading’ phase of each trial. Participants see a top–down view of the grid with objects obscured and successively click on blue squares to reveal ‘landmark’ objects at the location. After 16 clicks have been completed, a yellow square appears. Clicking on the yellow square reveals the ‘goal’ object for the trial. Bottom: schematic diagram of the navigation phase of each trial. Participants start in a random, previously unobserved location and are tasked with navigating to the ‘goal’ object they had just learnt about (displayed at the top). They can navigate in two ways. First, they could choose a direction to travel in by clicking on the corresponding arrow (highlighted yellow). This is analogous to using a ‘vector-based’ strategy. Alternatively, they could choose an adjacent state to travel to by clicking on one of the associated images (displayed in a random order; highlighted blue). This corresponds to using a ‘transition-based’ navigation strategy.

Reconstructing sounds from #fMRI data is limited by its temporal resolution. @ykamit.bsky.social &co develop a DNN-based method that aids reconstruction of perceptually accurate sound from fMRI data, offering insights into internal #auditory representations @plosbiology.org 🧪 plos.io/4fhNw1Z

Schematic overview of the proposed sound reconstruction pipeline. Left: DNN feature extraction from sound. A deep neural network (DNN) extracts auditory features at multiple levels of complexity using a hierarchical framework. Right: Sound reconstruction. The reconstruction pipeline starts with decoding DNN features from fMRI responses using trained brain decoders. The audio generator then transforms these decoded features into the reconstructed sound.
