030 | Predictive Processing 3: Neurobiology, Prediction, and Computational Psychiatry

December 3, 2020

In this episode, Gianluca and Jared discuss the neurobiology of predictive processing, the role of dopamine in reward signalling, satisfaction, and human desire. They also touch on the relation of reward to reinforcement learning and artificial intelligence. 

The podcast then shifts to discuss the clinical manifestations of the predictive brain, including the computational psychiatry of depression, autism-spectrum-disorder, and schizophrenia, and how top-down prediction, and precision-weighted prediction error explain central aspects of these conditions.

029 | Predictive Processing 2: Where The Action Is

September 3, 2020

This week’s episode of Bit of a Tangent is a continuation of our 3 part series on Predictive Processing - a fascinating neuroscientific account of the way our brains come to understand the world. If you haven’t already listened to part 1 (episode 028), check that out first! 

In this episode Gianluca and Jared discuss the importance of sensory precision, the circular causality of prediction and action, how action comes about in a counterintuitive way from high confidence predictions, the way in which prior expectations can bias sensory sampling, and how this could lead to self-fulfilling spirals that would make your life either much worse or much better!

It's here. It's finally here! The first in a series of three episodes diving into the predictive processing theory of brain function! Jared and Gianluca discuss top-down versus bottom-up perception, Bayesian Brain hypotheses, the logic of caring only about prediction error, and the phenomenology of visual illusions!

027 | 7 Practices to Survive the 2020 Apocalypse

August 11, 2020

Gianluca and Jared have survived 2020 (so far) and are back for Season 3 of Bit of a Tangent. In this episode they bring you 7 new habits and techniques that can be used to iteratively upgrade yourself — even in lockdown. Forget everything else that’s going on in the world, and take a deep dive into personal optimisation. Or, as they’d put it, prepare to geek out on organisation hacks, bootstrapped learning, and motivation pumps.

Jared and Gianluca exchange rapid-fire questions whilst becoming increasingly inebriated. Think of this episode as the Ferriss/Rose “Random Show,” but with more references to Bayesian inference. It’s pretty likely to entertain you, but hopefully you’ll find it interesting too. Topics include Email response times, VR projects, and the statistical approach to an ethical diet.
