98. Laura Wesseldijk: Behavioural genetics, music, and the importance of twins

Laura Wesseldijk works at the Max Planck Institute for Empirical Aesthetics in Frankfurt at the Behavioral Genetics unit in collaboration with the Department of Psychiatry at Amsterdam UMC. We talk about her research on the genetics of music and mental health, methods in behavioural genetics, the role of large samples, the importance of twins for behavioural genetics, and much more.BJKS Podcast is a podcast about neuroscience, psychology, and anything vaguely related, hosted by Benjamin James Kuper-Smith.Support the show: https://geni.us/bjks-patreonTimestamps0:00:00: Did Beethoven have bad genetics for music - or are there problems with applying (some) genetic methods to individuals?0:11:51: Different methods in behavioural genetics0:24:20: Gene x environment interactions and the difficulty of disentangling them0:30:30: 23andMe in genetics research0:37:26: Can you ask an interesting question if you need millions of people to have done a measurement?0:42:08: How to measure musicality (at scale)0:47:56: Geneticists really love twins0:50:41: Do critical periods in music exist?1:03:30: How Laura got interested in the genetics of music1:12:07: A book or paper more people should read1:16:17: Something Laura wishes she'd learnt sooner1:17:49: Advice for PhD students/postdocsPodcast linksWebsite: https://geni.us/bjks-podTwitter: https://geni.us/bjks-pod-twtLaura's linksWebsite: https://geni.us/wesseldijk-webGoogle Scholar: https://geni.us/wesseldijk-scholarTwitter: https://geni.us/wesseldijk-twtBen's linksWebsite: https://geni.us/bjks-webGoogle Scholar: https://geni.us/bjks-scholarTwitter: https://geni.us/bjks-twtReferencesBegg, ... & Krause (2023).
