This Week in the History of Psychology (which we call by the slightly silly name of TWITHOP)

was originally a weekly podcast, produced in 2006-07. It was written and produced by

Christopher D. Green, professor of psychology at York University in Toronto, Canada.


Since the original series (which is still available below) the format has evolved in various ways:

interviews, discussions, reviews – everything related to the history of psychology.

(I also toned down the bright red background that Vaughan Bell at “Mind Hacks” complained about!)


As always, the primary intended audience is students in college and university courses on the history of psychology.

We always welcome teachers using these podcasrts as “assigned listening” in their courses.
