OneStop Eye Movements (in short OneStop) is an English corpus of eye movements in reading with 360 L1 participants, 2.6 million word tokens and 152 hours of eye tracking data recorded with an EyeLink 1000 Plus eye tracker.
Each participant reads 10 Guardian articles paragraph by paragraph, and answers a reading comprehension question after each paragraph. After reading a 10-article batch, participants read two of the previously presented articles for a second time. Half of the participants are in an information seeking regime where they are presented with the question prior to reading the paragraph.
OneStop comprises four sub-corpora with eye movement recordings from paragraph reading, one for each of the following reading regimes:
1. [OneStop Ordinary Reading](https://osf.io/zn9sq/) - download this data if you are interested in a general purpose eye tracking dataset.
2. [OneStop Information Seeking](https://osf.io/kpbgx/)
3. [OneStop Repeated Reading](https://osf.io/4ay3t/)
4. [OneStop Information Seeking in Repeated Reading](https://osf.io/6ra7t/)
and three versions of the full dataset:
1. [OneStop](https://osf.io/azj2g/) - paragraph reading for the entire dataset.
2. [OneStop Full](https://osf.io/z7pyn/) - complete trials for the entire dataset, divided into the following Interest Periods: title, question preview, paragraph, question, answers, QA (question + answers) and feedback.
3. [OneStop Raw](https://osf.io/6f2km/) - complete trials for the entire dataset in EDF and ASCII formats.
[OneStop Metada](https://osf.io/jbd24/) includes a participant questionnaire and experiment summary statistics.
Overall, the dataset includes 19,438 regular trials, 9,720 in the **information seeking** regime and 9,718 in the **ordinary reading** regime. The dataset also includes 3,888 **repeated reading** trials, split equally between the two reading regimes.
