{"pk":49231,"title":"The Effect of Text Simplification on Reading Fluency and Reading Comprehension in L1 English Speakers","subtitle":null,"abstract":"Text simplification is a common practice for making texts easier to read and easier to understand. To which extent does it achieve these goals, and which participant and text characteristics drive simplification benefits? \n\nIn this work, we use eye tracking to address these questions for the first time for the population of adult native (L1) English speakers. We find that 42% of the readers exhibit reading facilitation effects, while only 2% improve reading comprehension accuracy. We further observe that reading fluency benefits are larger for slower and less experienced readers, while comprehension benefits are more substantial in lower comprehension readers, but not vice versa. Finally, we find that high-complexity original texts are key for enhancing reading fluency, while large complexity reduction is more pertinent to improving comprehension. Our study highlights the potential of cognitive measures in the evaluation of text simplification and distills empirically driven principles for enhancing simplification effectiveness.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Psychology; Language Comprehension; Natural Language Processing; Reading; Eye tracking"}],"section":"Papers with Oral Presentation","is_remote":true,"remote_url":"https://escholarship.org/uc/item/3tb1553f","frozenauthors":[{"first_name":"Keren","middle_name":"","last_name":"Gruteke Klein","name_suffix":"","institution":"Technion","department":""},{"first_name":"Omer","middle_name":"","last_name":"Shubi","name_suffix":"","institution":"Technion - Israel Institute of Technology","department":""},{"first_name":"Shachar","middle_name":"","last_name":"Frenkel","name_suffix":"","institution":"Technion","department":""},{"first_name":"Yevgeni","middle_name":"","last_name":"Berzak","name_suffix":"","institution":"Technion","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2025-01-01T13:00:00-05:00","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/49231/galley/37192/download/"},{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/49231/galley/38737/download/"}]}
