A deserving recognition for an incredible scientist and a great colleague. Congrats Nora! @noranewcombe.bsky.social

Congrats Nora!

Super cool paper Ken and team!

So excited that our work on children’s ability to discern real from AI-generated content received this recognition. We show that kids systematically misjudge some types of AI content as human, and that kids who use more technology in the home are worse at AI detection. Way to go Allison and team!

BREAKING: Scientists are staging a “science fair” in the lobby of a Congressional building to tell elected officials about the critical knowledge the US will lose because their research grants have been canceled.

Nice write up of our paper (with @vpmurty.bsky.social) showing that memories expressed with greater “authenticity” are more accurate, but people don’t use that information in judging whether someone actually remembers the event accurately or not, and instead use unreliable signals of accuracy.

This is great, and freely accessible!

Beyond honored! Credit to the amazing students and collaborators who I’ve had the incredible privilege to work beside along the way.

Alert! ... for the child development world!

“An Action Networks Model for Pain”

We propose a new model for chronic pain — and highlight two functionally connected cortical networks that could revolutionize how we treat it.

New research from MIT found that those who used ChatGPT can’t remember any of the content of their essays.

Key takeaway: the product doesn’t suffer, but the process does. And when it comes to essays, the process *is* how they learn.

Group-to-individual generalizability and individual-level inferences in cognitive neuroscience Much of cognitive neuroscience research is focused on group-averages and interindividual brain-behavior associations. However, many theories core to t…

This new article by @aaronjfisher.bsky.social, @mindimager.bsky.social, et al. is important for cogneuro research b/c it discusses the common yet problematic assumption that inferences based on group averages are applicable to inherently intraindividual processes. (1/3)

Exactly!

While the 'belief' plot draws attention, the core message of the final, deliberative consensus statements is that evidence linking smartphone and social media use to negative outcomes is limited, mixed, context-dependent, insufficient to support causal claims, and better research is needed.

Check if your university has signed. Write to your President if not.

screenshot of semantic distance R package information

New R package almost birthed - SemanticDistance - computes two semantic distance metrics (experiential and embedding) for any rolling chunk size (ngram-to-ngram, word-to-word, turn-to-turn, ngram-to-word). You give it your language sample. It does the rest, including lemmatize and stopword omit

Congrats Amy - some really great stuff in here!

Thinking about fMRI study designs for brain-based prediction? Updated preprint!

The research grants canceled this week will stop treatments in rural communities, will stop the study of cures for conditions that affect all people, and will take away jobs from lower and middle class folks who live in “red” states. Period.

NEW 🧵 Is human intelligence starting to decline?

Recent results from major international tests show that the average person’s capacity to process information, use reasoning and solve novel problems has been falling since around the mid 2010s

What should we make of this?

NIH Grants Fueled $95 Billion In FY 2024 Economic Activity, Finds New Report National Institutes of Health grants generated almost $95 billion in economic activity nationwide in FY 2024 according to a new report by United for Medical Research.

New report shows that NIH grants fueled $95 billion in economic activity and 407,782 jobs in 2024.

That's not to mention the countless lives that biomedical research has saved.

Show me a better investment than that.

Very excited that this fun collaborative piece with @aliocohen.bsky.social is now in press!

We highlight how insights from adolescent brain development can shape and enhance computational models of learning.

I love this Steve! What a powerful observation.

Awesome work from our student, Steven Martinez!

Linguistic properties of memory expression differentially relate to accuracy, specificity, and perceived veracity - Psychonomic Bulletin & Review When communicating our memories to others, we use specific language to represent and express those memories. However, whether the linguistic properties associated with memory expression, such as commu...

My lab’s latest paper, with @vpmurty.bsky.social. Memory for a scary real-world event (a haunted house) is reflected in the “authenticity” of expressed memories, but listeners mistakenly think accuracy is reflected in how “analytic” the expressed memory is - oops!

Maybe he’ll be announcing “concepts” of a deal.

Is there also a carrot to go with that stick? Is there an incentive to review for them? If not, why agree to review and take the chance the circumstances will prevent getting it in on time?

And now this!? These moves are going to complete destroy land at NzIH that do incredible and important work
