Psychology is a subject with a lot of different views and theories. Every psychologist has his own theories about how a human develops mentally, physically and, emotionally from childhood to adulthood. I would like to discuss three psychologists Ivan Pavlov and his theory of classical conditioning, Jean Piaget’s cognitive theory and, Albert Bandura and his social cognitive theory. These developmental theories have similarities and differences which I will be discussing further in this paper. The first developmental theory I will be discussing is classical conditioning. Classical conditioning is a developmental theory introduced by a man by the name of Ivan Pavlov.

Ivan Pavlov went to college at St. Petersburg University and was originally going to school for science but since he was bad at math he decided to go for physical science. He ended his schooling in the Academy of Medicine. Before Ivan Pavlov went on to develop his theory of classical conditioning “In 1904 he was awarded the Nobel Prize for his researches into the neural mechanism by which the secretion of gastric juices was stimulated.” (Harré, 2006) Classical Conditioning is a process of behavior modification by which a subject comes to respond in a desired manner to a previously neutral stimulus that has been repeatedly presented
along with an unconditioned stimulus that elicits the desired response. Ivan Pavlov liked to test his theories out on animals mainly dogs. An explanation of his studies with dogs is “In this type of learning, a neutral stimulus is paired with a
