The aim of contemporary cognitive neuropsychology is to articulate the functional architecture underlying normal human cognitive abilities, on the basis of patterns of performance over a variety of cognitive tasks involving subjects with varying degrees of brain-damage. An example of a contemporary functional architecture is the following model for the recognition and production of spoken and written words:
The modular processing components in this ‘box-and-arrow’ functional architecture represent functionally independent subsystems that perform computational transformations on the representations that originate as input along the connecting links, providing a theory of cognition at the algorithmic and representational level (not the implementational or ‘hardware’ level).
