How to decide whether a neural representation is a cognitive concept?
Maartje E. J. Raijmakers, Peter C. M. Molenaar · Behavioral and Brain Sciences · 1995
Abstract A distinction should be made between the formation of stimulus-driven associations and cognitive concepts. To test the learning mode of a neural network, we propose a simple and classic input-output test: the discrimination shift task. Feed-forward PDP models appear to form stimulus-driven associations. A Hopfield network should be extended to apply the test.
