Sentence understanding is affected by recent experience. Animportant open question is whether this reflects adaptationto the statistics of the input. Support for this hypothesiscomes from the recent finding that listeners can simultaneouslylearn and maintain the syntactic statistics of multiple talkers(Kamide, 2012). We attempt—and fail—to replicate this find-ing. This calls into questions whether recency effects in sen-tence processing originate in the same adaptive mechanismsoperating during speech perception (for which talker-specificadaptation is well-established).
