Last night
@laken77
played his 150th regular season NFL game! I am so proud — and I realized that my friends will have no idea how cool that is. So I put on my data girl hat and made these for you! First: what’s the distribution of games played among active players?
If the below math is correct, then my husband Laken Tomlinson (
#75
) will make his 75th consecutive start today (of 75 possible) during the 75th anniversary year for the Niners. If we win, we’ll be 7-5.

Laken Tomlinson has played in 73 of 73 possible games ever since coming to the 49ers in a 2017 trade. Jarring to hear that he’s hurt, but if Tomlinson is indeed limited in practice this week his track record of durability suggests that he’ll play against Minnesota
If you count 2 playoff runs, my husband
@laken77
has started 99 consecutive NFL games. So his 100th consecutive start will come this week vs the Lions, the team that drafted him. The start streak began 1 game after the Lions traded him away! Perseverance.

@laken77
But, like, has he just been in the league forever? The answer is — kind of! But he’s at the top of the expected number of games for his draft year (2015). Colors here reflect % games started!
All data are from , downloaded today (10/1/24), and filtered for active players (the download process only allows for 200 players at a time and I didn’t have it in me today to do all players or automate the process 😂)
So we know parent executive functioning (EF) relates to child EF, but WHY?
Do parents just pass down genes that underlie EF?
Do parents with better EF parent more effectively?
Do parents and children live in similar contexts that affect EF?

The win today was the 114th consecutive start for
@laken77
. That is 7 consecutive NFL seasons. SEVEN. And I think he played EVERY SINGLE SNAP on offense this season?! Amazing.
#NYJvsNE
Also, I want to point out the GARGANTUAN effort that is starting 99 NFL games. 99 weeks of 12+ hour days of practice, lift, treatment, yoga, PT, etc. If he’s sitting still, there’s an ice pack, hot pad, or compression boots involved. And film on. So proud

I am so excited to share that my first post-maternity-leave, first-author paper is out today. If you’d like, you can read it: .
Returning from maternity leave to academia is *scary*. This paper is special to me for a few reasons 🧵
My fab co-author Emily Bilek has left twitter, so it falls to me to share exciting new work! Along with an amazing team (including
@csmonk1
and
@KDFitzgerald_MD
on twitter) we found that a pared-down, exposure-focused CBT outperformed a relaxation control.
My amazing mentors
@DewindNick
and Liz Brannon stuck with this project (and me) for over 5 years! Nick and I found strong evidence that number is more salient than total surface area even before the start of formal education:
Worlds collide in about an hour! Excited to hear my husband

chat with one of my academic heroes

about the neuroscience of excellence
I took my 1yo to get her flu shot yesterday. I was surprised how much I pulled from my clinical training to help her with this hard thing. It was empowering! But made me think. A 🧵
I’ve got a manuscript to write this week but my goodness if the NFC Championship game isn’t a great motivator I don’t know what is

The terminology we use is important. I was recently told that neighborhoods may seem “dangerous” or “disadvantaged” from the outside, but those labels don’t feel appropriate to the people who live there.
#AcademicTwitter
, what words do you use that are clear but capture nuance?!
Took the day off to have some time with my 1yo after a wild month of internship apps. And we’re learning colors! (ok yes we’re eating large quantities of m&ms)
Not how I envisioned my defense but so grateful to have gotten here finally! A bonus of the virtual format was that more of my friends and fam were able to join ❤️ One step closer to Dr. Dots 🥳
NFL week 1 schedule released today and my husband is playing in Michigan. What a weird journey this has been. Covid permitting, do I invite my (twitterless) mentor to see him play for the first time?!
Wanna know how badly my cross-country flight with my 1yo just went?
The woman behind me just held her earplugs out to her husband and exclaimed BOY WERE THOSE WORTH IT
My friend

slows little kids’ biological aging. Super cool bio finding for a psychosocial intervention. 💜
I can’t believe how many people have seen my tweet! I thought my nerdy academic twitter circle would have fun with it but this is wild. Thank you all so much for the pro bowl votes! It would mean the world to him to get an invite! Now back to science ☺️
It’s a hot topic in the EF field, and one that felt super relevant to me while navigating the wild wild west of parenting a toddler. In collaboration with
@AlexWeigard
@KellyKlumpMSU
, and MTwiNS PIs Luke Hyde and Alex Burt, I took a twin-modeling deep dive! 2/🧵
I hope one day I can pay it forward and support another new parent as they try to get their scientific feet back under them! And I hope that the people who read this can think about how they can support new parents as well. 6/🧵
my Rmd is full of active verbs like “wrangle” and “wrestle” re: my data, meanwhile I’m sitting on my butt eating animal crackers in front of a computer
In case you’re curious, we found that harsh parenting activates genetic risk for CU traits, while warm parenting buffers that risk. With some interesting caveats that you can read in the paper!
Thank you for reading my 🧵!
But I didn’t just pull myself up by my bootstraps. It took a village! My PI Luke Hyde went above & beyond — even helped me proactively prepare for *mom brain* before Tay came. Alex Burt taught me the cool twin models.
@HaileyDotterer
read some AWFUL drafts and was kind. 5/🧵
Just tried to participate in a work call with my 4 month old in tow. She was extremely helpful — contributions included yelling, banging her toy on the table, and throwing her toy on the floor and yelling about it. At least her lil hair looked cute on the bottom of my screen?
Most importantly, it is special because I wrote it during a challenging & vulnerable time in my life — returning after mat leave. To have created something I’m so proud of reaffirms for me that science comes from *people* and it’s okay to be a scientist with a life 4/🧵
Worked on an *impossible* problem in R for an hour last night. This morning, realized within 1 min that my na.rm wasn’t inside the right parentheses. SLEEP, PEOPLE
First, it is special because it was inspired by my best friend and co-author
@HaileyDotterer
’s brilliant dissertation work. CU traits work is a little bit outside my wheelhouse, but this question was just *begging* for twin modeling, which I was determined to learn 2/🧵
My amazing academic circle I am SO sorry for all the NFL content today. Back to brains, executive functioning, and R complaints after tomorrow. Promise!
Nuclear twin family models indicated little evidence for family-level influences or for passive gene-environment correlation. Generally speaking, we did not find evidence for shared environmental influences on child EF, at least **as we measured it**, at all. 4/🧵
The Stress, Aging, and Relationships (STAR) lab at Texas Tech University is hiring a lab manager to start this September! Great opportunity for anyone looking to gain biopsychosocial research experience before applying for graduate school. Plz RT! 💫
@aaronjfisher
I took personal leave for a semester at UMich! Medical leave would have also been an option. I found the department to be flexible and supportive.
Where children & teens live is critically important to their cognitive development! Neighborhood poverty predicts response inhibition performance via brain activity, even when accounting for family-level factors.
Relatedly, it is special because the twin GxE methodology we employ is a *dream* method for me, and something I want to continue to use in my career. And now I know how to do it! 3/🧵

@PostAmie
I’m so glad!!! I was so excited about the topic that I tried to tackle a lot in one project, so there’s room for improvement and follow-up in a *lot* of areas (all of the areas?!)
@WiringTheBrain
@kph3k
This is something I’ve thought about a lot lately! So I’ve been interested in whether capturing commonalities across tasks a different way (computational modeling, thanks
@AlexWeigard
) yields the same results. TBD, but seems like no.
The skills I used were simple. I explained everything that happened in kid-friendly language before, during, and after. I explained what it means to be brave and brought a symbol for us to hold (Bluey!). I brought stickers for after in case the doctor didn’t have any.
Interestingly, both warm and harsh parenting had major shared environmental overlap with child EF. This is hard to interpret given low C estimates for child EF. However, it could reflect that there is a lot of commonality in parenting between twins, which then affects EF 7/🧵
Or it could mean some other stuff, which we discuss in the paper.
Also discussed are issues of defining and measuring EF! And many other things that I care about deeply. But this thread is already so long.
Thank you for reading!!! End 🧵
Similarly cool was using a bivariate ACE model to decompose the overlap between parenting and child EF into genetic, shared environmental, and non-shared environmental components. Pictured here for simplicity is the model for ONE twin. 5/🧵
Horses show evidence of mirror self recognition. After horses' cheeks were painted with a colourful mark in a spot they couldn't normally see, horses used the mirror to guide their movements and scratch at the marks, indicating a degree of self awareness.
This model is cool because we can ask whether parenting has significant covariance with child EF **separate from genetic confounds**.
And for harsh parenting, that is a yes! Harsh parenting (as per 2 caregivers + twin) has non-shared environmental overlap with child EF. 6/🧵
@bgonzo32
I use twin modeling to test questions about how genes and the environment (and their interactions) affect child outcomes. A few tweets ago I shared a recent twin publication I wrote! Yay twins!
Half the fun, as usual, was the twin modeling. I got to learn the Nuclear Twin Family Model, which incorporates parent measures on the phenotype of interest to estimate additional parameters (i.e separating C/shared environment into F/family- and S/sibling-level) 3/🧵
So, all simple. But a parent who has been up to something else (e.g. parenting!) and not thinking about kids and their brains for 6 years might not know to try / practice these skills.
And I’m happy to teach these skills, along with more complex ones, in a clinical setting. But I wish we could reach families way before they think about coming to see me! And at a much lower (and preferably no) cost to them.
When she cried (so much!) I calmly validated her — it hurts when we get our flu shot! I explained that we were all done with our flu shot until next year.
