EARLY VERBS IN BILINGUAL ACQUISITION<br />
3. Results 1 - General<br />
3.1 Latvian-English 250-word tokens<br />
Tables 3a and 3b show that Maija reached the 250-word whole-sample criterion<br />
one session earlier for Latvian than for English. She also has more ma<strong>in</strong> verb<br />
types and tokens <strong>in</strong> Latvian than <strong>in</strong> English. This is consistent with her<br />
development <strong>of</strong> the FCs Tense/Agreement <strong>in</strong> the two languages.<br />
Maija’s Latvian verb types generally <strong>in</strong>crease with age, while tokens show a<br />
fairly flat pr<strong>of</strong>ile, 41-60, apart from the unusual sample at 1;6. VTTR, apart from<br />
1;6, has range 0.27-0.44, with last 2 samples show<strong>in</strong>g the upper end <strong>of</strong> this<br />
range; from 1;8, it is close to the value for whole-vocabulary TTR (with<strong>in</strong> 0.05).<br />
Maija’s English verb types show a general <strong>in</strong>crease with age, as do tokens,<br />
except for peaks at 1;8 and 1;11, caus<strong>in</strong>g VTTR to dip to 0.35-0.38. All but 2<br />
samples (1;9, 1;10) show similar VTTR and TTR values (with<strong>in</strong> 0.07), which is<br />
also reflected <strong>in</strong> their means.<br />
We should also note that the English verb types cumulate to just 29 between<br />
1;6-1;11, while Latvian verb types reach 65, for the same sampl<strong>in</strong>g po<strong>in</strong>ts.<br />
