Peter Gray is Research Professor of Psychology at Boston College and author of Psychology, one of the main introductory textbooks, currently in its 5th edition. His textbook is one of the first to approach psychology as a whole from an evolutionary perspective. His past research concerned the nature of mammalian motivational mechanisms and his current research on childhood education and play was initially motivated by his son’s unsatisfactory public school experience, which, as you'll hear, caused him to investigate alternative schooling practices modeled after traditional societies and evolutionary theory.

Dr. Gray writes a weekly blog on the Psychology Today site, which can be found at http://blogs.psychologytoday.com/blog/freedom-learn.

One of his lectures comparing hunting-gathering societies to Sudbury schools can be found here: http://evolution.binghamton.edu/evos/projects/early-childhood-education-workshop/
