February 2023: Adversity, Toxic Stress, and Racial Disparities in Children, and Evaluating the Evidence for Brain-Based Biotypes

This episode of AJP Audio features two articles from the February issue of AJP.  First up, we have Nathaniel G. Harnett, Ph.D. (Harvard Medical School), discussing the impact of adversity and stress on racial disparities in childhood brain development among Black and White American children.  Following that, Ziv Ben-Zion, Ph.D. (Yale University), discusses a non-exact replication study of a study published in AJP by Stevens et al. (previously featured on AJP Audio) looking at brain-based biotypes to guide treatment following trauma.  And of course, we’ll check in with AJP Editor-in-Chief Dr. Ned Kalin about the rest of the February issue and how it all fits together.
