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

17:53 - Implementational level
18:51 - Relationship between levels
21:51 - Example: cash register
24:45 - Trade-offs
