It is a common finding across languages that young children have problems in understanding patient-initial sentences. We used Tagalog, a verb-initial language with a reliable voice-marking system and highly frequent patient voice constructions, to test the predictions of several accounts that have been proposed to explain this difficulty: the frequency account, the Competition Model, and the incremental processing account. Study 1 presents an analysis of Tagalog child-directed speech, which showed that the dominant argument order is agent-before-patient and that morphosyntactic markers are highly valid cues to thematic role assignment. In Study 2, we used a combined selfpaced listening and picture verification task to test how Tagalog-speaking adults and 5-and 7-year-old children process reversible transitive sentences. Results showed that adults performed well in all conditions, while children's accuracy and listening times for the first noun phrase indicated more difficulty in interpreting patient-initial sentences in the agent voice compared to the patient voice. The patient voice advantage is partly explained by both the frequency account and incremental processing account.
ARTICLE HISTORYdescribe an experiment that tests Tagalog-speaking children's use of word order and morphosyntactic markers for interpreting simple transitive sentences (Study 2).
Possible reasons behind children's difficulties with noncanonical sentencesDifferent accounts have been proposed to explain children's difficulties with noncanonical sentences. These claims shed light on the strategies that children use for sentence comprehension, and when children are expected to acquire noncanonical word order in different languages.
