A powerpoint I use in my Introduction to Psychology, Sociology, and Anthropology (grade 12)
The file discusses the Bystander Effect as a way to ease into the basics of psychology.
This also includes schools of thought (Psychoanalytic, Behaviourism, Learning Theory)
The slides end with a video clip of Bandura's Bobo experiment (children's response to seeing violent play). Unfortunately the video is currently not co-operating but it is available on Youtube and can be linked to the slide or downloaded to your computer and added to the file.
