<h3><u>
Explanation:</u></h3>
Psychology is the study of human behavior and mind. It helps in understanding how the mind works. When a person is studying psychology, he or she is applying the knowledge gained by studying human behavior and mind into day to day lives or other special scenarios. Psychology helps in defining the right and wrong human behavior in a set environment and attempt to correct the wrong behavior.
Behavior processes are the reactions that an individual gives after being exposed to a stimulus. For example, a child behaving in a gleeful manner as a response to a new toy. The behavior is gleeful gestures such as clapping, laughing or smiling which were brought out by the stimulus, new toy. Behavioral processes can be observed easily. Mental process is what happens inside the brain and something we cannot see. They are the ideas, opinions and thoughts that we have for a particular stimulus. Taking above example in consideration, the child displayed happiness because in his mind, the new toy is something to be happy about. That's his opinion towards something new.
