This podcast episode delves into the concept of semantic satiation, where repeated exposure to words, phrases, or even songs can lead to a loss of meaning or familiarity. It explores the physiological and psychological mechanisms behind it, drawing parallels to fatigue experienced by cells and the broader concept of reactive inhibition. The episode also examines the impact of semantic satiation on the popularity of songs on music charts and how classic rock songs can become overplayed and lose their emotional impact over time. Furthermore, it discusses how words themselves can evoke emotions and how repetition can affect our perception of language.
