(89) Stage 8 (2;2.23–2;3.17): F(L), NOGAP >> F(C) >>AGREE-L >>AGREE-R<br />

Anttila’s (1997) theory <strong>of</strong> <strong>variation</strong> predicts that quantities <strong>of</strong> <strong>variation</strong><br />

should be <strong>in</strong> small <strong>in</strong>teger fractions: e.g. 100%, 66% (2/3), 50% (1/2), 33%<br />

(1/3), 25% (1/4). The data at some po<strong>in</strong>ts do seem to show just this sort <strong>of</strong><br />

<strong>variation</strong>. To model smaller frequencies (see e.g. Stage 8: TOK), <strong>and</strong> gradual<br />

decl<strong>in</strong>es <strong>in</strong> <strong>variation</strong>, either a much richer constra<strong>in</strong>t set, or a richer model <strong>of</strong><br />

<strong>variation</strong>, such as that <strong>of</strong> Boersma <strong>and</strong> Hayes (to appear), would be needed.<br />

8. Conclusions<br />

In this paper, we have proposed an account <strong>of</strong> the three typological generalizations<br />

on <strong>child</strong> velar <strong>harmony</strong> first noted by Stoel-Gammon (1996) (see<br />

also D<strong>in</strong>nsen <strong>and</strong> O'Connor to appear on a typological generalization on<br />

manner <strong>harmony</strong>):<br />

(90) Proposed constra<strong>in</strong>ts<br />

a. directionality: AGREE-L >> AGREE-R<br />

b. target place: FAITHLAB, FAITHDOR >> FAITHCOR<br />

c. vowel block<strong>in</strong>g: NOGAP<br />

We have also shown how this account <strong>of</strong> these basic generalizations yields<br />

further specific predictions (i.e. <strong>in</strong>teraction <strong>of</strong> directionality with block<strong>in</strong>g<br />

effects <strong>of</strong> <strong>consonant</strong>s <strong>and</strong> vowels). Most <strong>of</strong> the grammars predicted by the<br />

factorial typology <strong>of</strong> these constra<strong>in</strong>ts were seen to be attested <strong>in</strong> different<br />

stages <strong>of</strong> the application <strong>of</strong> <strong>consonant</strong> <strong>harmony</strong> <strong>in</strong> one <strong>child</strong>'s longitud<strong>in</strong>al<br />

data. Predicted patterns <strong>of</strong> relative frequency <strong>of</strong> <strong>variation</strong> for the various<br />

word types were also shown to be <strong>in</strong>stantiated <strong>in</strong> Trevor's data.<br />
