Self-Esteem:

Amy Alkon labels Self-Esteem as the "Accepto-Rejecto-Meter":

"This accepto-rejecto-meter is basically a barometer measuring how much other people think we such (or rule!). It does this by monitoring the social environment for cues about where we stand. It's especially sensitive to negative cues - like indifference, dislike, and rejection - indicating that others' acceptance of us may be on the skids."

"The information the accepto-rejecto-meter picks up gives rise to emotions in us - the positive or negative feelings that we call "self-esteem"."

I am not so sure about that. E.g. if you acquire a certain (hard) skill you are forced to push yourself through a terrain in which you will experience quite some uncertainty about your knowledge and abilities. Then, with time, you will acquire skill and a certain amount of certainty. But this certainty isn't necessarily acquired by gaining much feedback from others. In some cases you gain this confidence by reflection of your skill level and by developing the ability to judge your skills accurately.

Nevertheless I like the term >Accepto-Rejecto-Meter<.
