Ever wonder why you can recognise your friend's face instantly but struggle to remember where you put your keys? Your brain is running the most sophisticated learning system ever created, and most of us have no clue how it actually works.

Nicholas Shea is an Oxford and King's College Researcher working in philosophy of mind, cognitive neuroscience and artificial intelligence.

He breaks down the fascinating psychology behind how we build concepts in our minds. Think of concepts as mental shortcuts - when you see a dog, you don't analyse four legs, fur, and a tail. Your brain instantly accesses everything you know about dogs.
