In this talk, Prof. Foote will present the results of two studies that examine the role of morphology in the production of agreement in L2 Spanish learners. This presentation will show that while mechanisms of number agreement seem to function similarly in native speakers and higher-proficiency L2 learners, in that morphological richness leads to decreased susceptibility to number agreement errors in both groups, the pattern of gender agreement errors is more complex. It may be the case that learners pattern like native speakers only when the non-default gender is in play.
