Dialect was not significant for either:

dialects.

Clefts are more prevalent in MAE, likely because the it is… construction
is existential in AAE, therefore blocking it from being used in a cleft.
Passives are used earlier and more often in MAE, likely because the
construction requires -ed, a morpheme often optional in AAE.
Age was slightly significant for SS, but not for OS:

a) Most primitively, the child could produce two independent
sentences, or a conjunction. These were counted as unsuccessful
attempts at relative clause production.
e.g. The cat’s sitting in the flowers and the man’s feeding it.
O
There are two types of interest in this study:
 SS: subject-subject
The relativized noun is the subject of the main clause and the relative
clause, as in
The mom who fed the baby is riding her bike.
 OS: object-subject
The relativized noun is the object of the main clause and the subject of the
relative clause, as in
The man fed the cat who was sitting in the flowers.
Previous research says that…
 in production, it is easier to relativize a subject than an object (Comrie,
1981),
 in comprehension, it is easier to parse an OS than an SS (Hamburger &
Crain, 1982; Kidd & Bavin, 2002)
Why might development of relative clauses in AAE-speaking children be
different?

Results
Two ANOVAs were run, one each for success on SS and OS
relative clause types. Dialect (AAE versus MAE), clinical status
(typical versus disordered) and age (4, 5, 6, 8.5) were the
independent variables.
Clinical status was highly significant for both types:

1. What is the difference between typically developing and
disordered children’s likelihood of producing a referent-specifying
relative clause at all?
2. Of the intended responses to both SS and OS items (i.e. SS relative
clauses and OS relative clauses), what relative pronouns were
used? Green has suggested that relative pronouns are more
optional and might be replaced by what in the adult AAE dialect
(2002). Is there a tendency for AAE speakers to drop the pronoun
or use a nonstandard one?
3. What strategies do children use in place of a basic relative clause?

Introduction
Interestingly enough, the only child to use a nonstandard relative
pronoun was an MAE speaker. All other zero uses were legitimate
(e.g. in reduced relatives). Use of relative pronouns by disordered
speakers was not analyzed due to small sample size (only 10
responses of disordered children included relative clauses requiring
relative pronouns).
Conclusions
1. The relative clause elicitation task proved to be a very useful diagnostic
indicator for children with language disorders. At the same time, it proved
useful for both AAE and MAE speakers, with no bias effects. However,
it is highly demanding.
2. Relative pronoun use did not show up differently on this task between
dialects, but this may reflect the limitation on types of relatives elicited. It
was not revealing for language disorder because so few disordered
children produced relatives at all.
3. Subtle dialect effects may be seen in the varieties of devices children use
in the task.
