Our purpose in developing the "Classic Films for Psychology" series is to make historical and near historical film of major figures in psychology available in a modern format. Most of the source material used in this project was orginally produced on 16 mm or 35 mm film stock, and some of it has not been available to researchers or instructors for many years. The intention was to find original film of the people and their work and to avoid re-enactments whenever possible. In some cases there is film of laboratory investigations made by the original researchers and in other cases there are interviews of major figures from the past and the recent past. The film used in this series is broadly divided into five categories, namely, Introductory Psychology, Experimental Psychology, Clinical Psychology and Personality, Developmental Psychology, and Social Psychology.
