The experimental studies on Kaqchikel reviewed so far suggest that the cognitive load during sentence comprehension is primarily determined by grammatical processes operating on linguistic representations, whereas word order selection in sentence production more faithfully reflects conceptual processing at the stage of event apprehension and preverbal message construction. In particular, agent-first orders are likely to be selected over others because of the conceptual saliency of agents. If this conjecture is on the right track, we would expect that the cognitive load during sentence production is higher for SVO sentences than for VOS sentences because the production of a sentence surely includes, as its central part, the construction of linguistic representations, and the grammatical processes involved in this are presumably similar to those involved in the comprehension of a parallel sentence, although there may be some differences. Chapter 10 reports on an experiment to verify this prediction. The results of this experiment support the conclusion that, although Kaqchikel speakers preferentially use the SVO word order because of the saliency of the subject, SVO sentences require more processing resources than VOS sentences both in comprehension and in production.
