Your cognitive skills at age two might predict your ability in adulthood - ABC listen We’ve known for some time that the first few years of childhood are critical when it comes to development. But a new study has highlighted just how critical the early years are for cognitive ability....

Last week I was interviewed in a (short) podcast about our new paper in PNAS

The twin work also showed that shared environment from year 1-2 predicted 10% of the variance in adult GCA, highlighting the lasting impacts of the infant environment.

Thank you to all our coauthors and the Colorado Longitudinal Twin Study participants. 4/4

We used twin studies & polygenic indices (PGIs/PGSs) which showed a rapid increase in the stability of GCA between ages 1 and age 7. Half of the variance in adult GCA was explained by genetic influences at age 7 or earlier, and two-thirds was explained by genetic influences at age 16 or earlier. 3/4

Two measures of infant cognition (a test of novelty preferences and tester-rated task orientation) given at age 7 and 9 months predicted general cognitive ability (GCA) nearly 30 years later. 2/4

Stability of general cognitive ability from infancy to adulthood: A combined twin and genomic investigation | PNAS Measures of general cognitive ability (GCA) are highly stable from adolescence onward, particularly at the level of genetic influences. In contrast...

We have an exciting new paper in PNAS on the stability of cognitive ability between infancy (7-9 months of age) and adulthood (~age 30). 1/4

I was awarded my first R01 grant last week! I'm really looking forward to taking another deep dive into the science of musicality in the coming few years in two very important datasets (CATSLife & ABCD).

I will also be looking for a postdoc (or potentially a PhD student to help with this project)!

Mutual implications of procrastination research in adults and children for theory and intervention - Nature Reviews Psychology Procrastination is often viewed as innocuous as long as deadlines are met but it is associated with negative life outcomes. In this Review, Mahy et al. bring together procrastination research in adult...

1/ When we partnered with 6th grade teachers to support students' executive functioning and math learning, I was struck by what the teachers wanted to know: What could be done about student procrastination? go.nature.com/3Yug81z

Great science so far at #BGA2024! With @psychgenomics.bsky.social @dangustavson.bsky.social @michelnivard.bsky.social @dr-appie.bsky.social, and who else here…?

Twin analysis show the association between brain age and EF decline was explained mostly by genetic influences and some nonshared environmental influences. Brain age is highly heritable (~62%), but heritability of EF changes are much smaller (19%)

APOE also predicts of executive function changes between 56 and 68, but it did not interact with brain age. Cognitive reserve also did not interact with brain age to predict EF changes.

Brain reserve in midlife is associated with executive function changes across 12 years We examined how brain reserve in midlife, measured by brain-predicted age difference scores (Brain-PADs), predicted executive function concurrently an…

Newly published study showing people with lower "predicted brain age" in midlife (mean age 56) have less decline in executive function abilities over the next 12 years.

Genes influencing loneliness and well-being are not the same as those on mood and anxiety diagnoses We generally think that genes which increase our risk for depression and anxiety disorders are the same as those which everyday depression and anxiety symptoms, but those with clinical diagnoses are j...

I'm curious what others think, but I feel we need to be more careful about including 'proxy' phenotypes in big GWASs of psychiatric disorders. The power for some genetic effects is definitely better but it may wash our or even hide other important genetic variation

There are a lot of dimensions mixed in the could cause differences (self-report vs. clinician, continuous ratings vs. case-control, etc.), but our findings are consistent across GWAS and twin/family approaches

We published a new study showing the genetic influences on depression/anxiety disorders are NOT identical to those on self-reported measures of loneliness, well-being (etc.)

Yesterday I taught my first lecture at the International Statistical Genetics Workshop (on gene-environment correlation). I'm very grateful to be part of this group!

Thanks for the invite @breunigsophie.bsky.social! Now that I'm here I guess this really is the official place for hot new science news...
