Overview#

OneStop Eye Movements (in short OneStop) is a large-scale English corpus of eye movements in reading with 360 L1 participants and 2.6 million word tokens. The dataset was collected using an EyeLink 1000 Plus eyetracker (SR Research).

OneStop comprises four sub-corpora, one for each of the following reading regimes:

Ordinary reading for comprehension
Information seeking
Repeated reading
Information seeking in repeated reading

OneStop Overview

We provide the entire corpus, as well as each of the sub-corpora separately. If you are looking for a general purpose eye tracking corpus (like Dundee, GECO, MECO and others), we recommend downloading the ordinary reading sub-corpus.

Key Features#

Texts and Reading Comprehension Materials#

Taken from the OneStopQA dataset (Paper Data 🤗)
30 articles with 162 paragraphs in English from the Guardian.
Annotations of part-of-speech tags, syntactic dependency trees, word frequency and word surprisal.
Each paragraph has two versions: an Advanced version (original Guardian text) and a simplified Elementary version.
Extensively piloted reading comprehension questions based on the STARC (Structured Annotations for Reading Comprehension) annotation framework.
- 3 multiple-choice reading comprehension questions per paragraph.
- 486 reading comprehension questions in total.
- Auxiliary text annotations for answer choices.

‘Reading Comprehension’ are datasets with a substantial reading comprehension component over piloted reading comprehension materials. The remaining datasets are general purpose datasets over passages or individual sentences. ‘Words’ is the number words in the textual corpus. ‘Words Recorded’ is the number of word tokens for which tracking data was collected. ‘NA’: data not available.

Controlled experimental manipulations#

Reading goal: ordinary reading for comprehension or information seeking.
Prior exposure to the text: first reading or repeated reading.
Amount of textual material between first and repeated reading: consecutive or non-consecutive article presentation (2-9 articles).
Paragraph difficulty level: original Guardian article (Advanced) or simplified (Elementary).
Question identity: one of three possible questions for each paragraph.
