Ep.03. The Pleasure Equation: What Music Reveals About Prediction and Reward

Episode 3: The Pleasure EquationPaper: Cheung, V.K.M., Harrison, P.M.C., Meyer, L., Pearce, M.T., Haynes, J.D. & Koelsch, S. (2019). Uncertainty and Surprise Jointly Predict Musical Pleasure and Amygdala, Hippocampus, and Auditory Cortex Activity. Current Biology, 29, 4084–4092.Key concepts covered: IDyOM, Shannon entropy, information content, musical expectancy, reward prediction error, nucleus accumbens, amygdala, hippocampus, incentive salience, liking vs. wanting, precision weighting, free energy principleFurther reading:Pearce (2018), Annals of the New York Academy of Sciences — IDyOM in fullSalimpoor et al. (2011), Nature Neuroscience — dopamine and musical chillsKoelsch, Vuust & Friston (2019), Trends in Cognitive Sciences — predictive coding and musicBerridge & Kringelbach (2015), Neuron — liking vs. wanting in reward neuroscienceHuron (2006), Sweet Anticipation — foundational theory of musical expectancyArc connection: Episode 1 showed the neural architecture of hierarchical predictive coding. Episode 2 showed the cognitive consequence — insight as maximum-intensity prediction error. Episode 3 shows the affective consequence — musical pleasure as precision-weighted prediction error. Three episodes, three levels of analysis, one framework.
