The dominant model that researchers use to represent information processing is based on which analogy?

• A. Computer
• B. Neural network
• C. Information processing model
• D. Human analogy

Answer: (A)

The way researchers typically model information processing uses a computer analogy. Think of the mind as a system that takes in input from the environment, encodes and stores information, and then processes it through a central “processor” to produce an output, such as a behavior or a decision. This framework helped early cognitive science formalize stages of processing—attention, perception, encoding, storage, retrieval—and to describe limits like processing capacity and serial steps. It provides a concrete, testable way to think about how information moves and changes as it’s handled, much like how data flows through a computer.

Other approaches offer different emphases. Neural networks model learning and cognition as parallel, distributed processing across many units, which is a different kind of analogy focused on brain-like connections rather than a sequential, computer-style sequence of operations. The information processing model itself is the name of the approach, not the analogy, and a vague “human analogy” doesn’t capture the specific mechanism researchers use to explain processing steps.
