This study investigated the processing load of transitive sentences in two different basic word orders (i.e., VOS and SVO) in Kaqchikel Maya, with a particular focus on the animacy of the object. The results of a sentence plausibility judgment task showed that VOS sentences were processed faster than SVO sentences regardless of the animacy of the object. This supports the traditional analysis in Mayan linguistics that, although SVO is the most frequently used word order, the syntactically determined basic word order is VOS in Kaqchikel, as in many other Mayan languages. More importantly, the results suggest that the processing load in Kaqchikel sentence comprehension is more strongly affected by syntactic canonicity than production frequency or object animacy.Keywords: Animacy; Sentence Processing; SO Word Order Preference; Syntax; Kaqchikel
IntroductionAccording to experimental findings from languages such as Basque, English, Finnish, German, and Japanese, sentences in which the subject (S) precedes the object (O) (SO word order = SOV, SVO, VSO) induce a lower processing load for comprehension than those in which the opposite occurs (OS word order = OSV, OVS, VOS), and thus, they are preferred by speakers (Bader & Meng, 1999;Erdocia et al., 2009;Kaiser & Trueswell, 2004;Mazuka, Itoh, & Kondo, 2002;Sekerina, 1997;Tamaoka et al., 2005;Tamaoka et al., 2013; among many others). However, these previous studies on sentence processing have all targeted languages in which the subject precedes the object in syntactically basic word orders (i.e., SO languages). Hence, it remains unclear whether the preference for SO is a reflection of word order in individual languages or more universal human cognitive features. What we refer to as individual grammar theory in this paper posits that a language's syntactically determined basic word order has a low processing load in comparison with other possible word orders (e.g., Gibson, 2000), whereas what may be referred to as universal cognition theory hypothesizes that SO word order has a low processing load regardless of the basic word order of any individual language (e.g., Bock & Warren, 1985). To verify which of these two theories is correct, it is necessary to examine languages in which the object precedes the subject in syntactically basic word orders (i.e., OS languages), for which the two theories develop different predictions. Koizumi et al. (under review) conducted a sentence-processing experiment in Kaqchikel, a Mayan language spoken in Guatemala. The syntactically determined basic word order of Kaqchikel is VOS, although in general, word order is relatively flexible (García Matzar & Rodríguez Guaján, 1997: p. 333).They found that VOS was processed faster than the two other commonly used word orders, VSO and SVO. This suggests that the preference for SO in sentence comprehension is not universal; rather, syntactic features of individual languages significantly influence sentence processing load. In other words, the individual grammar theory, rather than the universal cog...
