Description: Cue-based retrieval theories of sentence processing posit that long-distance dependency formation is guided by a cue-based retrieval mechanism: dependents are retrieved via retrieval cues associated with a verb. When retrieval cues match multiple similar items in memory, this leads to cue-based retrieval interference. A landmark study by Van Dyke and McElree tested interference from sentence-external items: retrieval cues were manipulated to (mis-)match semantically similar items presented prior to a target dependency. The support for interference of this type is weak, and only comes from English object cleft constructions. Our study provides a cross-linguistic investigation of interference from sentence-external items: Three eyetracking studies in English, German and Russian tested interference in the online processing of filler-gap dependencies under varying task demands. A fourth study attempted to replicate the Van Dyke and McElree study using self-paced reading. Bayes factors analyses show cross-linguistic evidence against interference from sentence-external items. A broader implication from these data is that cue-based retrieval interference is driven by sentence-internal distracting items, suggesting that a cue-based search is restricted to the current linguistic context.
