q2 · i? · associational · r1

Rule-adherence comparison for the final-y word group across the two samples; the author reports "the two phenomena coming together seem to show that more than simply the use of the rule is involved", offering as the only explanation that the word group may have received much greater emphasis with one teacher than the other.

"the value of this rule showed an advantage of 3 per cent, in the university group, but it lost an equal amount with the academy students."
