The correct answer is vicarious conditioning.
Vicarious conditioning refers to the phenomenon wherein individuals learn responses, attitudes and beliefs about something or someone (a stimulus), not through direct experience with a stimulus, but, rather through observing someone else's reaction to a stimulus. In this instance, Jackson "learned" to fear diving boards and deep swimming pools through observing his sister's traumatic experience with them.
Answer:
External locus of control
Explanation:
In simple words, People who have an external center of authority feel that events in their life are beyond their management, meaning that sometimes their own acts are the consequence of other causes such as destiny, misfortune, the persuasion of strong outsiders (such as physicians, cops, or government leaders), and/or faith.
Thus, from the above we can conclude that the correct answer is external locus of control.
