Early knowledge of word order in Palestinian Arabic: An eye-tracking study

This paper addresses the underexplored realm of early parameter setting in language acquisition before the two-word stage, in a less researched language, Palestinian Arabic. Building on Franck et al.’s (2013) exploration of the verb–direct or indirect object/direct or indirect object–verb (VO/OV) parameter in infants exposed to French, we investigate the acquisition of the VO order (as opposed to OV) in 17-month-old native Palestinian Arabic infants using a combination of the preferential looking paradigm, the weird word order paradigm, and pseudo-verbs. The results from our study show that Palestinian Arabic infants have established VO by the age of 1;5 and ignore sequences of ungrammatical OV. This pattern is different from that of the adults, who do not ignore ungrammatical sequences. Additionally, we find no correlation between the infants’ performance and vocabulary size or age within the range tested. The infants in the study constitute, with Mandarin infants in a similar study, the youngest age group to show sensitivity to the VO/OV contrast.
