😃Finally!!!😃 >> After more than 3 yr hard work together with @matteuler.bsky.social , I am delighted to share our Meta-Analysis about ALL studies linking Intelligence to the P300 ERP >> Small but significant effect size across 49 studies‼️https://biorxiv.org/content/10.64898/2026.02.13.705728v1

The psychological consequences of mental health awareness efforts - Nature Reviews Psychology Mental health awareness campaigns aim to decrease stigma, increase help-seeking and improve mental health literacy. However, they might also negatively impact how individuals interpret, label and resp...

New review paper led by @lucyfoulkes.bsky.social: Mental health awareness campaigns reduce stigma but can also lead to problematic self-diagnosis and symptom misinterpretation. These trade-offs matter, especially for adolescents.

Quilicura, Chile, one of the communities I wrote about in EMPIRE OF AI, has launched a brilliant initiative to inspire more responsible AI prompting. Today, don't use AI; ask the townspeople instead: quili.ai. So heartened to see this creative act of resistance.

US science after a year of Trump: what has been lost and what remains A series of graphics reveals how the Trump administration has sought historic cuts to science and the research workforce.

A year into Trump’s second presidential term, Nature presents a series of graphics that reveal the impact of his administration on science. 🧪

Interpreting EEG requires understanding how the skull smears electrical fields as they propagate from the cortex. I made a browser-based simulator for my EEG class to visualize how dipole depth/orientation change the topomap.

Congratulations to Libby DesRuisseaux and Caterina Obenauf, recipients of the 2025 Community Engagement and Service Award, whose work focuses on expanding access to neuropsych care, addressing health disparities, and building community-centered educational and support programs.

What does the future hold for Neuropsychology? I offer some ideas in my inaugural editorial, which appears in the journal's first issue of 2026.

Working memory readout varies with frontal theta rhythms Han et al. show that frontal theta oscillations rhythmically control access to working memory. The theta rhythm sweeps across the mental image, shaping behavior by coordinating spikes and beta oscilla...

A new paper finds ideological bias in research analyses:

Research teams composed of pro-immigration researchers estimated more positive impacts of immigration on public support for social programs, while anti-immigration teams estimated more negative impacts.

Aperiodic activity reflects pathological waveforms in epilepsy (and not necessarily hyper-excitability or altered E/I-balance). The 1/f slope goes up *or* down as function of waveforms during seizures. New work by Laura Heidiri and Frank van Schalkwijk from the lab: www.jneurosci.org/content/45/5...

A new PNAS paper finds that polarization increased immediately after the invention of smartphones and the advent of social media, which both appeared around the same year, 2008.

Some social media algorithms are feeding us antidemocratic attitudes and intergroup hostility.

But a new field experiment finds that an algorithmic feed can reduce out-group animosity & affective polarization by down-ranking this hostile political content.

Completely agree. And if I can make a self-promoting plug here, we have a nice table in this paper trying to separate some of these ideas out. The brain is very information-efficient (bits/ATP), while still being very expensive in energy consumption (ATP/sec).

So...my undergrad thesis student is doing a quality analysis of studies found in meta-analyses. She identified a few and we contacted the authors to request their effect sizes and other variables for the studies in their papers.

Here's what happened:

Plot showing metabolic rate and brain size vs. body mass. Warm-blooded animals expend an order of magnitude more energy and have brain sizes an order of magnitude larger

Soapbox time: the problem with metabolic efficiency arguments in neuroscience is that they often confuse energy efficiency with energy expenditure. Biological systems are optimized for energy efficiency, but that does NOT imply they are optimized for low energy expenditure 🧵 1/

So our campus just announced the six undergraduate programs being put on the chopping block.

One of them is Philosophy.

Philosophy.

Can we be a university without offering a Philosophy major?

Andrew R. A. Conway

Michael J. Kane

PS is excited to announce the launch of "Individual Differences in Cognition” (IDIC), an open-access journal on research in cognitive psychology, science, and neuroscience. Co-Editors-in-Chief are Andrew R.A. Conway & Michael J. Kane. Manuscripts accepted this spring. More information coming soon!

Andy Conway and I are honored to serve as inaugural co-Editors of this new Psychonomics journal, focused on the rigorous study of individual differences in cognition. Please spread the word to potentially interested colleagues; we hope that you will send us your best relevant work!

As we are having a discussion on neural codes: @earlkmiller.bsky.social is entirely right that the "only spike rates matter" idea that is so prominent in neuroscience has no credible evidence. We simply do not currently know how neurons code relevant information. Oscillations are likely part of it.

Half your brain cells are astrocytes, oscillating and modulating activity without spiking, while cortical neurons spike sparsely. So nearly 100% of cells are oscillating almost all the time, but only a minority of cells emit rare spikes. Maybe spikes are the tail and oscillations are the dog.

Check out our new paper in CABN (special issue on neuroscience of effort). @sarahdoesscience.bsky.social shows that acoustic challenge modulates aperiodic activity in younger and older listeners, effects correlated with hearing loss and distinct from alpha modulations.

Image of a flyer for an event. Top of the flyer has two logos: One that says "ANST NEUROTECH" over a transparent picture of a brain. The other logo says "SCN" and "ANST" with a photo brain a brain over the greek symbol for psychology, the letter Psi. Event hosts: "ANST NEUROTECHNOLOGY FOCUS GROUP × SCN DIVISION 40". The title for this event is: "Generative AI in Neuropsychology: Clinical, Ethical, and Training Perspectives". Event information states: "This joint session explores the growing role of generative AI within neuropsychology and broader healthcare practice. Trainees increasingly encounter AI tools in clinical work, yet guidance on ethical use, supervision standards, and skill development remains limited. Through complementary perspectives from clinical neuropsychology and law/technology, this talk will outline practical opportunities, risks, and professional considerations relevant across stages of training."

Join the ANST Neurotechnology Focus Group for their next talk on Wednesday, 11/19! Guest speakers Dr. Kathleen Bechtold and Dr. Claudia Haupt will explore the growing role of generative AI within neuropsychology and broader healthcare practices. Zoom Link: TINYURL.COM/GENAINEURO.

Expressions of blatantly immoral actions about outgroup members are growing on social media

This leads people to radically overestimate the degree to which political outgroup members support immoral actions

Democrats and Republicans are both off in their estimates. academic.oup.com/pnasnexus/ar...
