Answer:
The answer is Albert Bandura.
Step-by-step explanation:
The research work conducted by Albert Bandura in the 60s and 70s led him and his collegues to propose the observational learning theory that would also set the basis for the social cognitive perspective of learning. Observational learning challenged the main theory on learning that existed at the time, the operant conditioning theory. Observational learning suggested that there was more to the cognitive process of learning than respondent and operant processes alone.
