Upon a behavioral response, associations between stimuli and the response are integrated in a temporary memory trace named ‘event file’. Reencountering a component causes the retrieval of the entire event file, leading to interferences and performance impairments if only some parts are repeated and others are changed (partial-repetition costs). The stored conjunctions can not only include bindings between target and reaction, but also between task-irrelevant distractors and the response (distractor-response binding). Past research suggested that these links can be formed effortlessly without assumptions of capacity limitations. We specifically investigated the limitations for such bindings by testing capacity-related boundaries with different set sizes of polygon stimuli in a distractor-response binding paradigm. As a result, binding effects observable at a small set size were absent at higher set sizes, indicating limited capacities for event files.
