The purpose of the Grammar Elicitation Test was
to obtain multiple instances of a particular grammatical
target to act as a pre- and post-intervention measure of
treatment effectiveness. The tests consisted of 30 items
for each grammatical construction, spread evenly across
different allomorphs, where relevant. Pronoun tests contained
15 items for each pronoun (he and she). Items
were presented in a different random order for each
round of testing. Test items and instructions can be
found in appendix A.
All test items were pilot tested with a group of 17
typically developing 5-year-old children who scored at
ceiling on all tests. Any item produced incorrectly by
the typically developing children was replaced.
Each child first completed the Grammar and Articulation
Screening Tests. Following the screening tests,
a potential treatment target was selected for each child,
according to the procedure outlined below. In addition,
a second grammatical target was selected for each child
in the experimental group, to act as an untreated control.
Based on the results of the screening, the Grammar
Elicitation Test was then carried out, in order to collect
further data on each child’s selected grammatical targets
(treated and untreated). The Grammar Elicitation
Tests were administered three times, at nine week intervals.
Tests 1 and 2 provided a pre-treatment baseline.
