Abstract(in English) | Abstract Depending on your philosophy, connectionism lies somewhere between cognitive and neuroscience Levels for an explanation of mind/brain. Yet, as a bridge between these two levels connectionist models must be sufficiently detailed to make testable predictions at both ends. We show how connectionist models of relational knowledge can Link a relational theory of cognition to brain imaging techniques. The theory says that relational arity imposes a high processing load on working memory. A comparison of two connectionist methods suggests two differences where brain imaging techniques are likely to find discriminatory evidence relevant to the relational theory. First, the fi1ler-filler method(which binds component to component information) requires an exponential number of units as a function of arity, whereas the filler-role method(which binds component to position information) is linear. Second, the filler-filler method uses a different group of units for each arity, whereas the filler-role method does not. We suggest brain imaging experiments designed to measure neural activity as a function of relational arity. Should these experiments demonstrate a nonlinear increase in neural activation or a dissociation across tasks of different arities, then such evidence would be support for the relational theory. |
