Lecture 21: Synthesis

Question 1

decision tree

you’re in a particular state and then with every step, there are other options you can do

Question 2

hierarchical structure

Answer 2

as you move up the hierarchy, you get more and more abstract

so you start out at an abstract level and then you get more and more specific later on

Question 3

construal (low to high)

low: how are you going to do something <- concrete

high: why are you going to do something <- more abstract

Question 4

model free is storage

just storing what’s right and what’s wrong without thinking too much about it

having a model but computing it in real time

Answer 6

you have a plan…. you want to go from this state to another state

but then how you’re gonna get there is gonna be habitized

model free: tells you what to do but doesn’t tell you where you’re going

Question 7

different context favor storage or computation

Answer 7

different context favor storage or computation

Question 8

representational exchange

Answer 8

moving from model learning to model free or model free to model based

Question 9

rat in the maze (rapid retrieval)

Answer 9

rat is replaying the memory of the maze

reconsolidating for rapid retrieval
happens in the sleep cycle

Question 10

trying to recall random vs nonrandom chess pieces

Answer 10

remembers the nonrandom more (the ones he’s familair with) that he’s played before
