Possible Meanings:
1. Experiencing something through another person's actions: This interpretation aligns with the common understanding of "vicarious" as "experienced indirectly through someone else." In this context, "vicarious action" would refer to experiencing the consequences or effects of someone else's actions, even though you didn't personally perform them.
* Example: A parent feeling proud of their child's accomplishments, even though they didn't directly contribute to them.
2. Acting on behalf of another person: This interpretation emphasizes the "action" aspect. It implies taking actions that are meant to benefit someone else, even though those actions may not directly affect the person acting.
* Example: A lawyer taking legal action on behalf of a client.
3. Feeling a sense of agency through observing another person's actions: This interpretation draws on the idea of vicarious emotions. It suggests that observing someone else's actions can evoke a feeling of agency or control, even if the individual isn't the one physically performing the action.
* Example: A sports fan feeling a sense of accomplishment when their team wins, even though they didn't personally contribute to the victory.
