Experimenter Expectancies Video, Part I. The Discovering Psychology video series that I provide the link to below, contains an interview with Rosenthal concerning his famous study with grade school children and teacher expectancies.
The interview is in Program #20: Constructing Social Reality (scroll down the left hand side of the site and you will find it listed numerically). This same video contains footage of Jane Elliot’s brown-eyed/blue-eyed study, which also nicely illustrates the power of expectancies to shape behavior. The interview with Rosenthal begins approximately 12 minutes into the video and lasts about 5 minutes.
Again you can view these videos online at the link below (registration is might be required, I tried it and no registration was needed, but it’s free).

Experimenter Expectancies Video, Part II. The Discovering Psychology video series ( Link above) contains a description of an experiment to test the validity of lie detectors.
The segment is located in Program #2: Understanding Research. The segment begins approximately 20 minutes into the video and lasts about 4 minutes.
I expect you to view both video’s and answer the questions below ( Note: these questions can appear on an exam). Again, view the video and answer the following questions.
State several criticisms of lie detector tests, according to Leonard Saxe.
How do lie detector tests supposedly work?
In the experiment described in the video, what was the independent variable?
In the experiment described in the video, what was the dependent variable?
How do the results of this experiment relate to expectancies, as described in the textbook?
What was Rosenthal’s Research Question?
Why did some children “get smarter” than others?
What are the four factors that act upon the self fulfilling prophesy as stated by the researcher?
