Levels of Analysis

The mind is an extremely complex system! How can we ever hope to understand something so irreducibly complex? Vision neuroscientist David Marr had a big idea - we can understand complex systems like the mind by analyzing it at three distinct levels! 0:00 - Complex systems 4:16 - David Marr and the levels of analysis 13:33 - Computational level 15:29 - Algorithmic level 17:53 - Implementational level 18:51 - Relationship between levels 21:51 - Example: cash register 24:45 - Trade-offs 28:22 - Wrapping up 29:28 - Key concepts Sources: Friedenberg & Silverman (2021).
