This year, for the first time, someone in my undergrad anatomy class FINALLY chose to "do a make-up tutorial demonstrating the muscles of facial expression" for their assigned creative project and I am STOKED.

(the pic is a youtube tutorial I show for inspo, not a student!)

It's almost time for MSU's annual Science Festival! The SONiC Lab will be located in Room 2201 of the STEM Teaching and Learning Facility on April 5th and 6th from 11:00 AM-4:00 PM. Come "see your speech" and learn how acoustics can be used in healthcare applications! We hope to see you there!

It was great to connect with our community @msuscifest.bsky.social ! At the β€œsee your speech” station participants saw their speech and learned how speech acoustics help diagnose neurological conditions that affect speech! Baby Enzo joined in, enjoying his first of many Science Fests to come!

And the funding announcement for diversity supplements now has been updated to expire today. Supplements are so important to the careers of junior scientists. This is crushing for post docs and early career faculty

ASHFoundation’s 5th Annual Virtual 5K Walk/Run: Sparking Innovation with Every Stride The ASHFoundation’s 5th Annual Virtual 5K Walk/Run: Sparking Innovation with Every Stride is on Saturday August 31, 2024.

I just registered for my third year of the ASH Foundation 5k (Aug 31)! The ASH Foundation is a big supporter of early career research in CSD and I always appreciate having an external motivator to run :) runsignup.com/Race/MD/Rock...

chart showing measurements of fundamental frequency (pitch) and formant values for 34 iterations of the word "guilty" spoken by Ari Melber when reading the verdict

When a talker repeats the same vowel sequence 34 times in quick succession, a good phonetician simply can’t let that opportunity pass.
I present to you: the definitive acoustic analysis of Ari Melber's pronunciation of "guilty"

Cartoon titled: Annotated ToDo List
A sheet of paper with 'ToDo List' across the top and a bunch of numbered entries (that are not readable). Different entries are grouped with annotations to the side:
- things I need to do today (crossed out, replaced with) that are overdue
- something I wrote down that's already done
- things that have been on my list for days (crossed out, replaced with) weeks
- things that actually require multiple ToDo entries to complete
- No idea what this one is
- these are mission critical
- figure out what the 'mission' is
- full disclosure: these will never be completed and I totally know that

I have not seen this before but this is a very neat & helpful app. Just out of curiosity I just did a test run through it to see what the prompts/output looked like, but it fails to download (I get an error saying the failed download is because "site wasn't available" in Chrome.

MAKING TACIT KNOWLEDGE OPEN – A Panel Discussion Series
PART I: PRACTICES AND PRACTICALITIES OF PEER REVIEW (MAY 27, hybrid)

Panel Members: Marlene AltenmΓΌller (Social Psychology), Peter Edelsbrunner (Learning Sciences), Nathan Evans (Computational Modeling), Florian Pargent (Psychological Methods), Tobias Staudigl (Cognitive Neuropsychology), Charlotte Wittekind (Clinical Psychology)
Most researchers spend a significant amount of time and effort on peer reviewing. However, there is large variability in peer reviewing practices and little guidance for early career researchers on the topic. For this panel discussion, we assemble experts from different fields of psychology 

When: May 27, 16:00-18:00
Where: Leopoldstr. 13, Room 3322 and via Zoom 
Zoom details: Meeting ID: 691 6996 4466; Passcode: 706322

Are you an Early Career Researcher and unsure about how to write a peer review? Or simply curious about how other people write theirs?

In our new panel discussion series at @lmu-osc.bsky.social we'll discuss peer reviewing practices - you can join online or in person!

So many of my #praat scripts that I continue to build/tweak have become this kind of frankensteined mash-up of old and new syntactic norms, habits I've revised or broken, and stylistic preferences that very clearly age-grade my coding journey πŸ˜†

Hello World, and what better way to kick off our lab's social media than acknowledging World Parkinson's Day (April 11).

The Speech Outcomes in Neurogenic Communication (SONiC) Lab focuses on speech communication in neurodegenerative diseases like #Parkinsonsdisease.

Promo for the Science Fest: What can speech signals tell us about neurological disease?

How do we produce speech?
Speech occurs as a result of several highly coordinated movements between our lips, tongue, and vocal folds, all of which are directed by our brain. Some kinds of neurological diseases can affect movements in subtle or not-so-subtle ways, and these changes can affect how speech sounds as a result. 
Sometimes, speech changes can be the first indicator of a neurological condition such as Parkinson’s disease. 

How do we measure these changes? 
One way is to measure how other people hear and perceive speech differences, but another way is to directly measure the acoustic properties of speech itself!

Session will include:

1. Hands-on demonstration showcasing how we can visualize and analyze our own acoustic speech signal

2. Special considerations in speech changes that are common in Parkinson’s disease.

Yes the irony is this would have been much easier with blogdown, but everything else is much harder (for a student without a coding background). Oh well.

I sort of succeeded but also I mostly hacked it because SquareSpace is weird (but more more user friendly for student RAs than blogdown, hence the shift to squarespace).

...However, I will say my argument for it is waning with all the cloud-based, semi-version controlled systems the students have access to through the uni (Drive, OneDrive, etc).

If I do need students to learn git (e.g., for experiments, code), I have them use GitHub desktop.

I found the GitHub for Poets series a cute, soft intro to Git and version control more generally, and sometimes assign it to lab members if I want them to start using Git www.youtube.com/playlist?lis...

Totally agree. That’s where the distinction between β€œdoes it appear to be part of the true release (with continuous frication before the next burst)” vs β€œis this just a blip occurring before the actual release” comes in handy for me.
