In an eye-tracking during reading experiment, we examined how rapidly two types of photo-sentence relations impact sentence comprehension. The relation between a photo of a cultural figure and a year in an ensuing sentence (either the cultural figure in the photo was either alive in that year or not) was contrasted with relations between the same photo and achievements or facts about the cultural figure (e.g., a film they had vs. had not starred in). Longer reading times were observed at the regions containing mismatching year or fact, with more robust effects when data were filtered to include only trials in which participants had accurate prior knowledge about the cultural figure, their accomplishments, and their lifetime. These findings indicate that specific long-term knowledge is activated by a picture of a known figure and is rapidly available during language processing.

In two self-paced reading experiments, we investigated the integration of knowledge about cultural figures during language processing. Experiment 1 investigated how contextually-defined lifetime information (dead/alive) was integrated with temporal verb morphology (English Present Perfect and Past Simple). Experiment 2 investigated how long-term knowledge about a cultural figure, prompted by their picture, is integrated with two types of linguistic input in German: temporal phrases containing a year, and biographical information (e.g., Joaquin Phoenix: "In the year 2013 / *1960, I starred in the film ‘Her’ / *‘Psycho’"). Experiment 1 revealed longer reading times and higher rejection rates when life status mismatched tense (i.e., dead – Present Perfect, alive – Past Simple). In Experiment 2, shorter reading times and higher accuracy rates emerged in conditions containing lifetime-year mismatches. No effects were found for biographical information violations. Together, the two experiments provide cross-linguistic evidence that knowledge of a referent’s lifetime is integrated during language processing.

The present eye-tracking reading study investigated the real-time processing of the so-called Lifetime Effect, which involvesthe integration of temporal verb morphology and knowledge ofa referent’s lifetime (alive vs. dead). Critical stimuli containedfamous referents, meaning that their lifetime status is widelyknown. In addition, context sentences mentioned their lifetimestatus and occupation. Tense/aspect was manipulated in a fol-lowing target sentence to contain either the present perfect orthe simple future (e.g., She has performed / will perform...).For dead referents, the target sentence was infelicitous giventhe tense/aspectual marking; for living referents, the mark-ing was felicitous. This design permitted us to examine ef-fects of lifetime status conveyed via world knowledge and lin-guistic context on the processing of tense/aspect morphology.Eye-tracking reading times revealed longer total reading timesat the critical (verb) and post-critical regions for the presentperfect when following a deceased context, while the dead-simple future condition had shorter overall reading times thanany other condition. Naturalness ratings revealed the dead-simple future to be quickly and reliably rejected, while thedead-present perfect was deemed acceptable. However, thelatter was rated significantly lower than the living/present per-fect condition. Taken together, the results imply that worldknowledge and an immediate context defining a real-world ref-erent as being dead or alive can jointly modulate the processingof subsequent verb tense/aspect, but with striking differencesbetween the present perfect and simple future.
