The goal of this experiment was to test explicit instruction of when irregular verbs take a change in the stem, and when they use a regular affixation pattern. We gave beginning Spanish students practice conjugating verbs that have irregularity in some inflected forms. Two irregularity types were compared: stem-change verbs, where the pattern of transformations is predictable based on a large gang of similar irregular verbs, and spelling-change verbs, where the pattern of transformations is predictable based on the spelling and the phonology of the inflected form and the infinitive. We compared explicit formulations of "when to change" the stem of a verb with an analogical comparison condition, where instead of a rule formulation, participants saw a similarly irregular verb they knew (judged by the instructor) conjugated appropriately as a model.
