Our new preprint w/ @edvogel.bsky.social presents a neural marker of a competition/interaction taking place in working memory between memory and current goals. We label it r-CDA Check out preprint for details about r-CDA and other interesting neural dynamics osf.io/preprints/ps...

calling all researchers who collect data from humans 🧠🧪 we are running a very brief survey (<1 min) about jsPsych, the software ecosystem for browser-based data collection. if you use jsPsych, or if you collect data with any other software, please fill it out at tinyurl.com/jspsych-census!
I am writing on behalf of the leadership of jsPsych, the software ecosystem for browser-based data collection used in experiments and surveys from many labs worldwide.

It has been difficult for us to figure out how widespread jsPsych usage is, because the software is freely available online and we do not collect any information about downloads, users, experiments posted online, etc. While the software has been cited in thousands of articles, jsPsych usage is likely more widespread than those citations imply, because not every project using jsPsych leads to a citation, and because there are also often substantial delays between actual jsPsych usage and a publication. As such, we are conducting a very brief census of jsPsych users.

If you collect data from humans using jsPsych or any other type of software, we would appreciate your filling out a very brief survey (<1 min) at tinyurl.com/jspsych-census. This will help us to understand how many people, labs, and institutions are current or former users of jsPsych, information that will help support the long-term sustainability of the jsPsych ecosystem.

We would also appreciate it if you could circulate this message to your lab, your department listserv, and your collaborators, to help ensure that it reaches as many members of the research community as possible. The survey is being distributed by Josh de Leeuw, Melissa Kline Struhl, and myself. Please contact me (sam@auckland.ac.nz) off-list if you have any questions about it.

New paper: across 3 EEG experiments, we examined how do we edit WM at test. Imagine you were asked to memorize 4 colored squares during encoding: at test, when you were given a single test probe, are you able to remove the items at irrelevant positions (upper), or do you have to keep'em (lower)? 1/n

We've known that socioeconomics (SES) matters for the 🧠. New & 🤯 is that SES drowns out all other brain associations, incl. IQ. If you train an algorithm to predict IQ from brain data, it's still way better at predicting SES. Science Mag: www.science.org/doi/10.1126/... @smarek0502.bsky.social 👀🧵👇

Check out my poster at #VSS2026 in banyan breezeway tomorrow afternoon! We find that stimulus memorability parameters (hit and FA rate) robustly affect performance in a task with no recognition memory requirements (visual search with trial-unique images). With @utochkin.bsky.social and Ed Awh

A multi-lab replication effort (@eegmanylabs.bsky.social) of the contralateral delay activity (CDA) has just been published online! In brief, the set-size effect appears to be robustly observed, but CDA correlation with VWM capacity is not reliably strong. doi.org/10.1016/j.co...

Recently, van der Stigchel and colleagues posted a provocative commentary suggesting that we should be wary of bots in online behavioral data collection (🧵by @cstrauch.bsky.social here: bsky.app/profile/cstr...). But should we? Here is my response letter osf.io/preprints/ps.... 1/5

Spatial attention and working memory are popularly thought to be tightly coupled. Yet, distinct neural activity tracks attentional breadth and WM load. In a new paper @jocn.bsky.social, we show that pupil size independently tracks breadth and load. doi.org/10.1162/JOCN...

1/ Why are we so easily distracted? 🧠 In our new EEG preprint w/ Henry Jones, @monicarosenb.bsky.social and @edvogel.bsky.social we show that distractibility is associated w/ reduced neural connectivity — and can be predicted from EEG with ~80% accuracy using machine learning.

Not looking forward to this getting quoted - may be one of the dumbest words committed to judicial opinion. Don't assume that "experts" are correct, but assume that judges are better at science than scientists?

UChicago has ~$108 million in NIH grants. According to most recent F&A rate info I found (2019-20), UChicago has an F&A rate of 62% for on-campus grants, so around $67million in F&A support. If the rate is cut to 15%, that’ll be a loss of $50 million in support. That’s thousands of jobs lost

One doctor’s recommendation to deny a 43-year-woman coverage “contained errors on practically every aspect” of her condition, the Labor Department said in 2012. United and other insurers continued to hire the doctor over the next decade. propub.li/3BQjJ1e

Insurers Continue to Rely on Doctors Whose Judgments Have Been Criticized by Courts
In dozens of cases ProPublica reviewed, judges found that some doctors working for these companies engaged in “selective readings” of medical evidence and “shut their eyes” to medical opinions opposing their conclusions.
