Information processing theory has been a significant player in cognitive psychology, human-computer interaction, and other related fields. The theory focuses on how people acquire, store, retrieve, and use information from their surroundings. Over the years, several theorists have played crucial roles in forming and shaping the information processing theory.
The purpose of this article is to provide a comprehensive understanding of the evolution of information processing theorists. Let us delve into the past to know more about the theorists who have contributed to this theory.
George Armitage Miller, a psychologist, was the first to introduce the concept of “chunking.” He stated that the human mind has a limited capacity to hold information at a time. He further explained that by grouping several units of information, memory capacity could be increased, and more information could be processed. This concept brought about a shift in how researchers viewed short-term memory processes.
The introduction of Chunking laid the foundations for Herbert Simon and Allen Newell’s theory of information processing. They came up with the idea of the computer simulation model and created the first Artificial Intelligence system. This model focused on human cognitive processing and provided insight into how the brain processes information. They suggested the three principles of input, output, and processing, which are still relevant to cognitive psychology today.
Another significant player in the information processing theory is Donald Broadbent. He made significant contributions to the area of selective attention and proposed the “Filter Theory.” His theory stated that the human mind filters out irrelevant information while focusing on relevant information. This concept played a vital role in how people understand selective attention and divided attention, which is still in use today.
In contrast, Atkinson and Shiffrin’s modal model of memory theory suggested that there are three distinct stages of memory: sensory, short-term, and long-term memory storage. Short-term memory is where people hold information for about 20 seconds, while long-term memory storage is where people store information indefinitely. This concept provided the foundation for research in how memories are stored in the brain.
Other notable theorists include Jean Piaget, who proposed the cognitive developmental theory, and Lev Vigotsky, who introduced the Social Development Theory. Both theories explain how cognitive faculties develop and evolve over time. Jean and Lev believed that humans acquire processing skills through social interactions and cognitive development.
In conclusion, the information processing theory has evolved over the years through the contributions of various theorists. From Miller’s concept of chunking to Atkinson and Shiffrin’s modal model, and the introduction of computer simulation models by Simon and Newell. Donald Broadbent’s selective attention concept and the development theories of Jean Piaget and Lev Vigotsky, the information processing theory has evolved.
By understanding the evolution of information processing theorists, you can appreciate how the theory has changed, developed, and the contributions of each theorist. These contributions have formed the theories we know today, and their research continues to influence our understanding of how the human brain works.
