Table 3. Counterexamples to ordering relations among<br />

grammatical morphemes<br />

____________________________________________________________________________<br />

Total instances consistent with relations given in Table 3 = 881<br />

Total instances inconsistent with relations given in Table 3 = 98 (10%)<br />

Analysis of counterexamples:<br />

(a) within 10 percentage points = 49 (50%)<br />

(b) within 20 percentage points = 9<br />

(c) where percentages not given: one rank difference = 16<br />

(d) where percentages not given: two ranks difference = 9<br />

(e) studies producing "true" counterexamples (not (a)-(d) above):<br />

1. Uguisu (Hakuta, 1974) = 5<br />

2. Larsen-Freeman (Imitation I) = 2<br />

3. Jorge 11 (Rosansky, 1976) = 1<br />

4. Dolores (Rosansky, 1976) = 2<br />

5. Andersen, 1976 a = 1<br />

6. agrammatic individual subjects (de Villiers, 1974) b = 4<br />

____________________________________________________________________________<br />

a: Number of obligatory occasions not known.<br />

b: Obligatory occasions known to be more than ten but may be less<br />

than twenty.<br />

consistently positive but often statistically insignificant correlation one sees between L1 <strong>and</strong> L2 scores<br />

when rank order correlations are used.<br />

Figure 1 gives a proposed "natural order" for second language <strong>and</strong> for Broca's aphasia, <strong>and</strong> was<br />

constructed from the relations given in Table 2. It is extremely interesting to note that all "Monitor-free"<br />

Fig. 1. Proposed "natural order" for second language acquisition <strong>and</strong> agrammatics<br />

studies using adult subjects (except Imitation I) show a healthy positive correlation with this order 1<br />

(Table 4).<br />

The data presented here strongly confirm the reality of a "natural order", a reliably occurring order in<br />

longitudinal <strong>and</strong> cross-sectional,<br />
