Joanna thinks to herself,"I'm motivated to do well at this job because I don't want to disappoint anybody." Joanna is demonstrating which form of motivation?

A) external motivation
B) external regulation
C) introjected regulation
D) intrinsic motivation

Joanna is demonstrating introjected regulation, which is a form of internalized motivation that comes from a sense of obligation or guilt rather than personal interest or enjoyment (intrinsic motivation). It is not external motivation (A) because it is coming from within Joanna and not from a reward or punishment from an external source. It is also not external regulation (B) because it is not stemming from a need to conform to external expectations or rules.
