About this listen
This paper published in 1986 introduces the concept of Parallel Distributed Processing (PDP) models, offering a new perspective on how human cognition works, contrasting it with traditional sequential processing. It explores how the brain handles complex tasks like perception, motor control, language understanding, and memory retrieval by simultaneously considering multiple, often ambiguous, pieces of information. The text provides concrete examples such as reaching for an object, skilled typing, stereoscopic vision, and word recognition to illustrate how interconnected processing units interact through excitatory and inhibitory signals to arrive at solutions. Furthermore, it touches upon the origins of PDP models, highlighting their physiological plausibility and their ability to learn and generalize spontaneously by adjusting connection strengths between units based on experience.
