Data for: Why wait for the verb? Turkish speaking children use case markers for incremental language comprehension
The datasets include: (i) the raw gazedata collected by Tobii T60 eye-tracker in the visual-world eye-tracking study by Ozge, Kuntay, and Snedeker (accepted for publication in Cognition) that test the predictive interpretation of case markers by Turkish-speaking children and adults; (ii) the processed version of this data used for various types of analyses, and (iii) the data for the relatedness study, which is the norming study we conducted to test to what extent the topic entity (the first entity) in each item used in the eye-tracking experiment is related to the other entities it appears in each context (i.e., plausible agent and plausible patient). The aim of the visual-world eye-tracking experiment was to see whether children are able to interpret the case marking on the first noun in an utterance to predict the thematic role of the upcoming entity in the utterance before this second entity and the verb appears. In Experiment 1, we used utterances that had a verb-medial order (i.e., Noun1-Verb-Noun2) and we found that while adults were able to use the case marking information prior to the verb information, children were able to do so only after the verb was available. In Experiment 2, we used verb-final utterances (i.e., Noun1-Noun2-Verb) that allowed more time to process the case marking on the first noun and we found that children were similar to adults in using the case marking information to predict the identity of the second noun prior to the second noun and the verb.
