agrammatically. But the presupposition of this interpretation is that children, normally,<br />
process sentences the same way as adults and that only the grammatical module is<br />
affected. Our data suggest that the modularization is the final state of language<br />
development, perhaps an evolutionary optimal way of processing language data with<br />
limited capacities. SLI children do not reach this stage, not in the extent their peers do.<br />
The obtained data show how conservative the hypotheses 2.2., 2.2.1 and 2.2.2. are. They<br />
can all be confirmed since they predicted only latency shifts <strong>for</strong> relevant components.<br />
Indeed, the latencies of the P600 were later both in ‘case-chi’ and ‘tense-chi’ experiments<br />
in the SLI group, as predicted in the H2.2.1 and H2.2.2. The only prediction that could<br />
not be confirmed was the later latency of LAN in ‘case-chi’ experiment due to the fact<br />
that LAN was not obtained in this experiment neither in the TLD group nor in the SLI<br />
group (H2.2.1.). Lack of difference between experiments was not directly predicted, but<br />
it is exactly this similarity between results in different experiments which allow <strong>for</strong><br />
making a stronger claim: since SLI children lack dissociation between different aspects of<br />
syntactic processing, they lack adult-like modularized sentence processing.<br />
Compensatory mechanisms that can be observed on a behavioral level correspond to this<br />
developmental trait of children with SLI. In this respect the hypothesis 2.3. stating that it<br />
is not to be expected that children with SLI lack only one language component (but that<br />
the deficit is more general, on a processing level) can be fully confirmed.<br />
