The difference is essentially one of phonological analysis.

But what is routine in phonological analysis often presents problems in syntactic analysis.

The orthography matches the phonological analysis as above except:

Other researchers believe that the N400 occurs much earlier, before words are recognized, and represents orthographic or phonological analysis.

This description is based on acoustic analysis and contemporary forms of phonological analysis.

Shaw (1991) provides a phonological analysis of this process, using data from research on Tahltan language.

This assumption is predicated upon the following textual and phonological analyses:

These fragments do not contain tables, but describe the phonological analysis that underlies them.

In most phonological analyses, all vowels are treated as occurring with the time frame of one mora.

This example shows clearly how the units of phonological analysis can sometimes be seen to differ from those of grammatical analysis.
