What is naturalistic observations?
Records behavior in natural environments (It describes behavior)
People don’t know they are being watched
What is courtesy bias?
Participants try to please or look good to the researcher
What is participant bias/Hawthorne effect?
Tendency of research subjects to respond in certain ways because they know they are being observed (Why subjects can’t know they are being watched)
