However, there was significantly
greater gain for the treated targets than the
untreated targets between tests 1 and 2 (t(18) = 3.29,
p = 0.004) and between tests 2 and 3 (t(18) = 4.01,
p = 0.001). Thus, experimental group performance
on untreated grammatical goals did not change over
the three test times. Furthermore, whereas change in
the treated and untreated goals did not differ in the
