The importance of exemplar psychology in cognitive science and memory research can’t be overstated. It’s like finding the missing piece of a jigsaw puzzle that suddenly makes the whole picture clearer.
For example, we know of three different algorithmic-level versions of exemplar theory (Kruschke, 1992; Lamberts, 2000; Nosofsky & Palmeri, 1997), which all make slightly different assumptions. The neural model proposed here is the first known implementational-level version, and it shows that some qualitatively different psychological assumptions are compatible with the quantitative predictions ...
