Human Information Processing : cognitive science
The information processing theory approach to the study of cognitive development evolved out of the American experimental tradition in psychology. Information processing theorists proposed that like the computer, the human mind is a system that processes information through the application of logical rules and strategies. Like the computer, the mind has a limited capacity for the amount and nature of the information it can process.

Finally, just as the computer can be made into a better information processor by changes in its hardware (e.g., circuit boards and microchips) and its software (programming), so do children become more sophisticated thinkers through changes in their brains and sensory systems (hardware) and in the rules and strategies (software) that they learn.

Human information processing theory deals with how people receive, store, integrate, retrieve, and use information.

Since the first computers, psychologists have drawn parallels between computers and human thought. At its core are memory models. The memory model which dominated the 1970’s and 80’s is the three component information processing system of Atkinson and Shiffrin (1968, 1971) inspired by typical computer hardware architecture:

  • Sensory Memory (STSS): Analogous to input devices such as a keyboard or more sophisticated devices like a voice recognition system
  • Short Term Memory (STM) or working memory: Analogous to the CPU and it’s random-access memory (RAM)
  • Long Term Memory (LTM) : Analogous to a storage device like a hard disk
