In most languages, most of the syntactic dependency relations found in any given sentence are projective: the word-word dependencies in the sentence do not cross each other. Some syntactic dependency relations, however, are non-projective: some of their word-word dependencies cross each other. Non-projective dependencies are both rarer and more…

On-line comprehension studies of flexible word-order languages find that noncanonical ("scrambled") structures induce more difficulty than canonical structures [e.g., Hyona & Hujanen, "Q. J. Exp. Psychol." 50A (1997) 841-858], with this difference being attributed to the structural complexity/infrequency of these forms. However, by presenting…
