Psycholinguistics in the field, CUNY Sentence Processing poster

Posted on Updated on

We presented the results of the animacy and accessibility study on Yucatec on March 18, 2010 at the CUNY Sentence Processing Conference in New York (see image below, or download the poster pdf file here: CUNY 2010 Sentence Processing poster Yucatec. See poster pdf file for additional data, abbreviations and references). We encountered a lot of support for our project and a lot of enthusiasm for continuing research. Soooooooo, stay tuned for more production studies on Yucatec to be carried out this summer.

Results of animacy and accessibility in Yucatec

Posted on Updated on

Good news! We’ve analyzed the previously mentioned experiment on animacy and word order in Yucatec. We coded animacy of the Agent and Patient referents (human, animal, inanimate), transitivity (transitive, intransitive) and voice (active, passive, other) of the verb. We also coded the definiteness of the Agent and Patient referents (definite, indefinite).

Overall, Agent-Verb-Patient word order was strongly preferred (see Table 1). Moreover, human subjects were more likely to appear earlier in the sentence (ps<0.0001, interaction n.s., N=597), which is predicted by direct accessibility accounts. Human agents and patients were were more likely to be described as definite (ps<0.0002), and definite NPs showed a tendency to be mentioned earlier (agent: p<0.0001; patient: n.s., interaction p<0.0001). Still, the effect of animacy held independently (ps<0.002; interaction n.s.). The agent animacy effect was somewhat mediated by an effect on transitivity (whether participants described an event as e.g. an apple hitting a man or an apple falling on a man in that inanimate agents were less often described transitively (p<0.0001; no patient effects). The agent animacy effect remained significant even for transitive sentences (p<0.004; no interaction, N=502). In terms of the effects of voice, human agents correlated with the use of active voice (p<0.0001), and human patients correlated with the use of passive voice, though not at strongly (p<0.03, N=604).

Table: Word order and voice

Word order Total Active Passive Other

Patient-Verb-Agent 63 2 61 0
Other 28 20 7 1

What does this mean? Good news! Interesting results. In Yucatec, the passive voice is encoded by verbal morphology. Passive voice does not presuppose or preclude a word order change. When a patient was human, sentences were more likely to be in the passive voice. Moreover, human patients were more likely to be mentioned earlier. So, we’ve seen the use of passive voice morphology and earlier mention with human patients.
