a) vicarious conditioning
Explanation:
Vicarious conditioning is a type of indirect learning that occurs when an individual learns how to respond to a stimulus by observing how another individual responds to that same stimulus upon exposure. Feelings, attitudes, beliefs can be learnt through vicarious conditioning by simply observing other people's response acquired, towards a stimulus.
