Answer to Question 1
ERG is an expanded version of the Maslow hierarchy of needs. ERG stands for Existence, Relatedness, and Growth. Existence corresponds to Maslow's lower order needs of physiological and security needs, relatedness corresponds to the social needs, and growth corresponds to the esteem and self-actualization needs. Existence is the need for immediate needs related to staying alive, food, shelter, etc. Relatedness is the need for interaction and to be valued and accepted by others. Finally, growth needs are related to the need to feel self worth and believing you are competent and achieving all you are capable of.
There is some disagreement as to the exact relationship between these needs but all agree individuals do have these needs.
