8 years ago, I started a science magazine. There was a critical gap between speech science and non-experts, and I also wanted to provide writing and outreach instruction to undergrads. Check out our latest issue here, headed by Portia Washington: thespokenworddigest.substack.com

What a whirlwind it's been! I came here in 2018 to work as a lab manager not knowing anything about speech or language and came away with more knowledge than I know what to do with (though, I still have a lot to learn)! Thank you to @emilymyers.bsky.social for your mentorship and the LAB Lab!

NEW DOCTOR ALERT! Hannah Mechtenberg successfully defended her dissertation on Monday. @hannahmech.bsky.social is a phenomenal science communicator and basal ganglia expert that I tricked into doing a language science PhD with me. Congrats, Dr. Mechtenberg!!!

Hannah posing in shades and with a "Dr. Mechtenberg" nametag which is how you can tell she's got a PhD.

Why are we so good at adapting to "sub-optimal" speech? I argue, in this review paper, that adaptation may be driven by the combined action of dopamine and norepinephrine via prediction error signaling. It's early days with this idea, but I'm excited to have it out there and to keep exploring more!

Stop, drop everything and pick up this new review paper from LABlab member @hannahmech.bsky.social. In it, Hannah argues for considering speech adaptation through the lens of reinforcement learning. Good stuff. link.springer.com/epdf/10.3758...

Absolutely thrilled to share the 🌟 FIRST PAPER 🌟 from ACORN Lab! 🐿️ I’m beyond proud of all-star grad student @heatherarobinson.bsky.social for this review of “exposome” effects on neurodevelopment & cognition! Paper here rdcu.be/ezUqx & thread below 👇 /1 #neuroskyence #PsychSciSky #devsky #cogdev

From farm to faculty. Writing home to his community in Minnesota, Prof Jim Magnuson explains that the powerhouse behind U.S. research is the infrastructure, paid by “indirect costs”. “This system has made U.S. science the strongest in the world.” 🧪🏠 www.hometownsource.com/county_news_...

As you listen to a story, the meaning of each word you hear relates to the meaning of prior words. But how? We operationalized semantic distance, and identified brain regions that correspond to this rolling summary measure during naturalistic listening. #neuroscienceoflanguage

Check out our preprint (linked again here: osf.io/preprints/ps...) where we measured neural sensitivity to changes in semantic space while listening to a podcast. Not only do we look at word-to-word but larger chunks too (2-gram, 5-gram, 10-gram) to examine meaning construction at multiple levels.

A figure showing neural sensitivity to semantic distance at multiple chunk sizes. The panels show activation in the superior temporal gyri and frontal regions that varies in relation to changes in semantic distance.

Our new work led by the incomparable @hannahmech.bsky.social examining brain sensitivity to semantic distance jumps between rolling ngrams (each new word to n-words before it) during auditory narrative perception. osf.io/preprints/ps...

In this new pub we ask whether a small rewards (cents) might get people to learn the phonetic details of talker more quickly (e.g. a s--sh shift). Answer: probably not. The fact that we got to title the paper "Cents and Shenshibility" was just a bonus. Explainer below!

Hannah Mechtenberg@hannahmech.bsky.social · last yr.

New science alert!!! Myself, Shawn Cummings, Sahil Luthra, & @emilymyers.bsky.social tested whether monetary reward during talker-specific phonetic recalibration biased listeners to learn more about one talker vs another. The results are complicated? doi.org/10.3758/s13414-025-03048-z (1/thread)

Thank you for the shout-out! We have an open-source model (osf.io/db79q/) for anyone who wants to start a lab digest -- it leads your writers through all the skills they need to learn about public science communication! Stay tuned for our 10th issue that will be released soon!

@hannahmech.bsky.social's and Portia Washington's research digest (written by a "passionate group of undergraduate researchers") sharing and communicating research on speech, language and hearing science. A really wonderful project. thespokenworddigest.substack.com

Today, a broad coalition of scientific professional societies who represent over 92,000 scientists are speaking out against the politicization and demonization of Federally funded science and government scientist jobs. It was an honor to help the Union of Concerned Scientists with this! 🧪🌎

If you need a break, come visit our new Substack space where you can read articles that translate work in speech and hearing science, aphasia, caregiving, and more. It's a small drop in the bucket, but increasing the reach of critical knowledge feels worthwhile: thespokenworddigest.substack.com

Ever been curious about what happens in your brain when there is a topic shift during listening? I thought so. @hannahmech.bsky.social has some answers for you. But also more questions?

Hannah Mechtenberg@hannahmech.bsky.social · 2y ago

In case you missed it at @psychonomicsociety.bsky.social's annual meeting - I worked with @jamiereillycog.bsky.social, @jpeelle.bsky.social, and @emilymyers.bsky.social to model changes in semantic distance during a podcast, which correlated with neural activity! drive.google.com/drive/u/0/fo...

A snippet from a poster. At the top is a heading reading, "The pattern of neural sensitivity to semantic distance during naturalistic listening varies based on region: from the STG to the supramarginal gyrus." Below the heading are graphical depictions of brains with the activation patterns on them. The four types of activation are: semantic distance, just word events, lexical frequency, and phonological neighborhood density.
