Chapter 13 observes how representative theories of sentence processing costs fare in accounting for the relative difficulties among Kaqchikel sentences with different word orders. The relative processing costs associated with Kaqchikel transitive sentences with the four different word orders are correctly predicted by the Hierarchical Distance Hypothesis, whereas the relative processing costs associated with the corresponding four transitive constructions in Japanese are correctly predicted by the Linear Distance Hypothesis. However, the relative processing costs in these languages are also consistent with the assumption that they are shaped by the combined effects of the three factors: production frequency, linear distance, and hierarchical distance, suggesting the cognitive uniformity of the human parser.
