Brain Rules for Learning – Dr. Medina #ls2011

It’s a myth that we use only 10% of our brain.  We use 60%-80% of our brain depending on what we are doing.

The brain designed to solve problems to survive in outdoors setting while in motion (paraphrased badly).

Memory – relevance to the present

Wiring – relevance to the future

Memory is not fixed at the moment of learning.  Repetition in timed intervals provides the fixative.

Memory is actually controlled forgetting.

Short-term considerations
30 to 40 memory gadgets in our brain and it’s the crosstalk that makes memory happen.

Memory is not a unified concept. Let’s talk about declarative memory because we know something about declarative memory.

If the brain decides it is declarative memory, it goes through a process that is known.  You can hold onto 7 pieces of declarative information for 30 seconds (immediate memory). If you don’t repeat it within 30 seconds, you will lose it. Once it is repeated (within 30 seconds), it is held for 2 hours (working memory).  If you don’t repeat it after two hours, you will lose it.

If you hear something you like, you will set up your own repetition cycle (in your brain).

IDEA ALERT: Bust your learning into 20-minute segments then repeat it every 2 hours.

Journal of a Memory Trace

How long does it take for a recruited piece of info get into long-term storage? It takes a decade. Google – systems consolidation.

Hippocampus converts short term memories into long term memories.

Start phase: Info slams into the hippocampus and then pushed out to the surface.

Alert phase: 30 seconds and 2 hours – hippocampus and the surface share the memory back and forth.

Nomadic phase: memory goes somewhere for 10 years (they don’t know exactly where) but the hippocampus and the surface are still sharing the info back and forth. Info is still up for corruption during this 10 year time period.

Final phase: After 10 years (for reasons unknown), the hippocampus lets the info go and the info is permanently stored in the surface.

Wiring Consideration

Every brain is wired differently from every other brain and learns in ways unique to that wiring.

All brains are wired alike at the interstate and state road level.  Brains are wired differently at the city streets and alley level. And learning takes place at the city street and alley levels.

A two-part learning strategy
Create a database and then improvise off of it

Fluid intelligence and crystallized intelligence = Fact, fact, fact then improv

Gist and detail as a function of resolution:  There are are three things wrong wrong with this sentence.  Can you find all three?

Theory of Mind – the ability to peer into someone’s mind and understand the rewards and punishments system of that mind
