In this article, two types of behaviors, classical conditioning, and instrumental conditioning will be analyzed with the use of an example to enhance the understanding.Classical conditioning which is also known as Pavlovian conditioning was named after the person who made it famous. It is a type of conditioning which relates a stimulus that initiates the response known as unconditional stimulus with a response that does not initiate stimulus known as the conditional stimulus. Several articles have been written regarding this topic with scientists such as John Watson concluding that the conditioning explains every aspect of the human psychology. Classical conditioning became the basis for the development of the famous behaviorism theory used to explain different phenomena in the field of psychology to date. The theory of behaviorism has several assumptions that are all based on the classical conditioning.The first assumption is that the acquisition of behavior or rather learning takes place due to existence and interactions in a particular environment. The assumption contradicts the biological opinion that some characteristics of an individual or animal, in general, might be inherited from the parent. Shaping of the behavior takes place due to environmental forces. It is a point that can be related to adaptation for survival in a particular environment that is evident from the various examples if comparisons of behaviors of people in different parts of the world. The third assumption based on classical condition is that mental thoughts and emotions of an animal have nothing to do with behavior and character. A closer look at the three assumptions and one can clearly see the similarity whereby they all try to relate behavior and the environmental factors likely to affect the behavior of the animal.The classical conditioning theory can be divided into
