The new big thing in the field of psychology and its natural connection to other sciences is in the field of behavioral economics. I will do some posts on some recommended books later, but for now, you can get your feet wet with an episode of NOVA on PBS called Mind Over Money. I've collaborated with my economics colleagues and have gained some fascinating insights into human behavior as a result of learning more about this field of decision making and money. It also will give you additional examples of any aspect of cognitive psychology.
The show first airs on April 27 and is viewable online on April 28, 2010.
