Which type of learning occurs when we observe how other people act?

A) insight learning
B) operant conditioning
C) classical conditioning
D) observational learning

Observational learning occurs when we observe how other people act and learn from their behavior. It involves a process of modeling, where we imitate the behavior of others that we have observed. This type of learning can be particularly powerful when we see someone being rewarded or punished for their behavior, as it influences our motivation to imitate or avoid that behavior.
