The PDP approach
To
semantic cognition
James L. Mc Clelland and
David E. Rumelhart pioneered the field of brain models based on parallel
distributed processing and their book, Parallel Distributed Processing.
Explorations in the Microstructure of Cognition (the MIT Press, Cambridge,
Massachusetts, USA, 1986), became the new bible for cognitive scientists who
believed brain functioning much the same of a number of neural networks working
together. In the past two decades the Parallel Distributed Processing (PDP)
research group developed very interesting strategies for the study of cognitive
processes and new theories, which attracted many neuroscientists, cognitive
neuro-psychologists and mathematicians. Jeoffrey Hinton, among others, gave
them his precious contribution.
James Mc Clelland and
Timothy Rogers wrote a review of the PDP approach to semantic cognition in the
Nature Review Neuroscience (J. L. Mc Clelland & Timothy T. Rogers,
The Parallel Distributed Processing approach to semantic cognition,
Nature Review Neuroscience, 4, 310-322, 2003).
