Hosts' Personal Stories Of Accent Convergence
- Laurie Santos and Angela Duckworth each experienced accent convergence while living abroad and with roommates.
- Laurie adopted a faux British posh accent in Oxford and Angela and her New Orleans roommate became indistinguishable by voice by senior year.
Behavioral Contagion Drives Accent And Mannerism Mirroring
- Behavioral contagion is an evolved tendency for people to unconsciously copy others' mannerisms and accents.
- Laurie Santos cites the chameleon effect research by John Bargh and Tanya Chartrand showing experimenters' small movements trigger unconscious mimicry in subjects.
Mirror Neurons Are Real But Overstated
- Mirror neurons exist mainly in motor cortex and respond when we see actions we could perform, but their role is limited.
- Laurie cautions against overhyping mirror neurons as the full explanation for empathy or complex social learning.
