The commentators have raised some interesting issues but none question the
viability of a localist approach to connectionist modelling. Once localist
models are properly defined they can be seen to exhibit many properties rel
evant to the modelling of both psychological and brain function. They can b
e used to implement exemplar models, prototype models and models of sequenc
e memory and they form a foundation upon which symbolic models can be const
ructed. Localist models are insensitive to interference and have learning r
ules that are biologically plausible. They have more explanatory value than
their distributed counterparts and they relate transparently to a number o
f classic mathematical models of behaviour.
