Impression management:
There are different types ( like managing appearances, ingratiation)
so it varies, but in a nutshell it's basically a means of "keeping up with appearances" or trying to give yourself a more positive view from others.
3. Back stage self: It's basically your unfiltered self. Ex. Someone who's really kind an polite in the work place (front stage), but once they get home they're loud and swear a lot (back stage)
4. Hawthorne effect
A teacher watches you so you do your work
A police officer watches you so don't miss behave.
I'm drawing a blank on the first one though?
