College Classes
Over the course of 50 years, I’ve taught nearly every psychology course there is. In the left column below are 12 of my favorite classes. I’ve included my notes, summaries and handouts. In the middle column you’ll find special topics. And on the right are videos I’ve made.

Learning
But let me address the larger perspective. Learning is something you already do automatically. I mean that you do it without thinking, as a natural process. But also that you haven’t thought about or tried to improve it. You are using learning right out of the box.
Memory
Think of memory as a large house with limited storage space. There are a lot of rooms but few closets. The goal is not to fill every corner but to select significant and valuable elements to put on display. Some items are in long term storage but the majority of the resources are to facilitate daily living.
Memory is vital to daily living, and always has been so. Knowing where the Saber Tooth Tiger lives is important information. It is in the best interests of your survival to be able to store and retrieve the proper information at the right moment in time. Tigers tend not to wait while you ponder the matter or shuffle through your notes to find the right answer.
