Introduction The information processing theory approach is the study involving cognitive development in psychology. Developmental psychologists who recognize and use the information processing perspective note that mental maturity is as a result of the child’s basic components changing (Shaffer & Kipp, 2010). This equates the human mind to a computer whereby the information processed is from the environment that enters the mind through the attention mechanisms. Thus, the theory of the mechanism of the human brain relates and addresses the growth of the child’s mind. This is with respect to the processing of information in an advanced manner, as well as responses to the information received. This theory emphasizes the continuous pattern of development. In the model where human beings are viewed as computers, the comparison of the two is used to comprehend the manner in which the information is handled by individuals. In the model, information is taken in or simply it is input. Then, it is encoded through the processing system to give a meaning that is compared to the stored information. A good example is the central processing unit of the computer where the information is encoded, given a meaning, and compared to the previously stored information (Shaffer & Kipp, 2010). Four Pillars of the Information Processing Model There are four pillars that underlay and support this model. These include rationality that embraces various aspects such as perception, coding, and storage of information within the mind of an individual. Secondly, there is the analysis of the stimuli. In this case, there is a change of the encrypted stimuli in an effort to facilitate the decision making process within the brain. There are four sub-processes that form the alliance to enable the brain come to a conclusion concerning the encoded information it receives and stores. These four include encoding, strategization, generalization, and automatization (Shaffer & Kipp, 2010). Thirdly, there is the situational modification where an individual uses experience by a collection of memories that are stored to control a situation of the same manner in the future. Lastly, there is the obstacle evaluation that enhances the maintenance of the subject’s development level. The obstacle at hand is always taken into consideration when evaluating the subject’s intellectual, problem solving, and cognitive acumen. There are times when misleading information can confuse the subject. Thus, the subject may not find it easy to solve issues at hand (Shaffer & Kipp, 2010). The Information Processing System The information progression includes three elements. The first aspect is the sensory register. The second one is the short-term memory. The last element of the information process is the long term memory. The sensory system has a sensory store. This is where information is received and stored temporarily. The information is held in the sensory register for a long time to allow unconscious processes to operate on the traces of the information. There is the short-term working memory, which is also called the center of the unconscious thought. This is usually equated to the analogous to the central processing unit of the computer. This is where information fr
