A podcast about the methods and metascience of developmental science, cohosted by Jessica Logan @jarlogan and Sara Hart @saraannhart. We talk about developmental sciencing, including data collection, data analysis, research methods, and open science, as well as life in academia. Think about it like a lab meeting where you don’t have to do the readings and never have to present.

S3E5: Trajectories have variance too!

Trajectory of heritability to the heritability of trajectories?

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.

Paper mentioned that examined the heritability of general cognitive ability across ages.
