 Aydede (1995, 1997a) agrees that there is a legitimate notion of non-concatenative constituency structure, but he questions whether the resulting models are non-classical. He denies that we should regard concatenative structure as integral to LOTH. According to Aydede, concatenative structure is just one possible physical realization of constituency structure. Non-concatenative structure is another possible realization. We can accept RTT+COMP without glossing constituency structure in concatenative terms. On this view, a neural network whose operations are sensitive to non-concatenative constituency structure may still count as broadly classical and in particular as manipulating Mentalese expressions.
