1 Lecture 3: Learning Fall 2007 Prof. Lombrozo Overview of today’s class: 1. Learning at the computational level 2. Basic learning mechanisms - Classical conditioning - Operant conditioning - Causal learning 3. A learning illusion - Illusory correlation 7.2 Learning at the computational level • What is the goal of learning? – To extract information that supports adaptive behavior. • To accurately predict the future • To successfully control the environment • Why is learning hard? – Evidence is consistent with many possibilities; only some will support adaptive behavior. 7.3 Classical conditioning

Pavlovian humor 7.5 • Information value: CS must predict US • Makes sense given goal of learning!
