S3E5: Trajectories have variance too!

<p><em>Trajectory of heritability to the heritability of trajectories?</em></p> <p>Measuring growth in skills and abilities over time is practically (maybe literally!) synonymous with developmental science. In this episode, Jess and Sara talk about how static measurements of a skill can have different variance, and different predictors, from growth in that skill. After a general discussion, we dive into how that plays into estimates of heritability, and the difference between the trajectory of heritability and the heritability of trajectories.</p> <p>Our Response paper: <a href="https://psyarxiv.com/qtwhg/"><u>https://psyarxiv.com/qtwhg/</u></a></p> <p>Uchiyama and colleagues “<a href="https://www.cambridge.org/core/journals/behavioral-and-brain-sciences/article/abs/cultural-evolution-of-genetic-heritability/9CBEB629203EA430B6EE5549C5E729FC"><u>Cultural Evolution of Genetic Heritability</u></a>” from 2021. &nbsp;Behavioral and Brain Sciences</p> <p>Paper mentioned that examined the <a href="https://www.nature.com/articles/mp200955"><u>heritability of general cognitive ability across ages</u></a>.</p> <p>Sara’s lab meta-analysis summarizing<a href="https://link.springer.com/content/pdf/10.1007/s10519-016-9810-6.pdf"><u> heritability of reading</u></a>.</p>
