Language and other complex behaviors: Unifying characteristics, computational models, neural mechanisms

Shimon Edelman
2017 Language Sciences  
With this conceptual framework in mind, I compare and contrast computational models of language and evaluate their potential for explaining linguistic behavior and for elucidating the brain mechanisms  ...  A remedy for this methodological impasse is to augment Marr's three levels (problem, algorithm, and implementation) with two additional and related perspectives on the phenomenon in question, which are  ...  In addition, as one may expect given that they implement abstract binding, vector symbolic models do not rank high on neural plausibility.  ...
