While the computer analogy is limited and limiting, information processing theory has provided a structure for the study of cognitive processes in children. The actions taken by humans are likened to a computer output. The processes of thinking-perception, problem solving, and memory-are similarly compared to the computer's data reading, data processing, and storage capabilities. Information processing theorists liken the sensory input to humans to the input functions of a computer. In the early 1980s, information processing pioneer Robert Siegler suggested that children's ability to reason improved with age, and that an older child is able to draw upon a greater variety of mental processes than a younger child. The task of integrating the two lists was much more difficult. Subjects found it easier to repeat the numbers if they could first list all digits presented to one ear, and then list the digits presented to the other ear. Broadbent based his theory on research that involved a listening task: subjects in Broadbent's study were presented with pairs of digits, one in each ear, and later asked to recall them. Broadbent formulated the first information processing theory, known as Broadbent's theory of attention. In applying information processing theory to child development, researchers examine the maturation of mental processes to explain changes in problem-solving behavior, decision-making, information gathering and storage, and other cognitive processes. In information processing theory, the human being is analogous to a computer. Information processing theory was developed to help social learning theorists and others understand how humans learn and solve problems. With the information stored in relative isolation, learning and processing is very limited, and when current experiences trigger those memories, a person re-experiences the negative sensory. Information Processing Theories Information Processing is how individuals perceive, analyze, manipulate, use, and remember information. A strategy for the study of cognitive development. The ideas about memory that emphasize the processing of information in stages, or steps are known as information-processing theories or models.
