A number of stimulating books in psychology can provide insights and inspiration for developing creative thinking.
For example, in her NY Times article The Power of Concentration, Maria Konnikova reports on a University of Washington study on the effects of meditation training on multitasking.
She is author of Mastermind: How to Think Like Sherlock Holmes.
According to some research, we can only do or cognitively focus on one thing at a time. That is one of the themes of the PBS presentation based on the book Super Brain, by Rudolph E. Tanzi and Deepak Chopra.
