So being in college, I often walk everywhere. I usually listen to music while walking around - it kills the street noise, I can drown out the beggars and gutter punks, and just makes a short walk enjoyable. I was wondering if you guys know of any audio on TRP or theory behind it that I could use to replace the music and more immerse myself in TRP, perhaps some evolutionary psychology. A podcast or radio show would be preferable. Thanks.
