Answer:
Three test environments were selected for our experiments: a law office, a laboratory in which experiments were performed using laboratory rats, and an automobile assembly line.
One-way mirrored glass panels were installed to allow video cameras to record the activity and researchers to observe the same and take notes.
We secretly inserted observers directly into the work environment. These observers posed as outside contractors and were in uniform as maintenance and cleaning staff, coffee and water service vendors, and similar supporting personnel.
The observers were drawn from the students who had been matriculated into the experimental psychology courses from which this study was developed as an example of such studies generally.
