Perception bias in assessing rodent welfare during euthanasia and anaesthesia

Raw eye-tracking data This folder contains anonymized raw eye-tracking exports generated during a laboratory experiment investigating perception bias during the evaluation of rodent anaesthesia and euthanasia procedures. Eye-tracking recordings were collected continuously while participants observed four 75-second video stimuli depicting mice undergoing either: direct CO₂ euthanasia, or isoflurane anaesthesia followed by CO₂ euthanasia. Videos were presented with either correct or incorrect contextual framing labels (“Anaesthesia” or “Euthanasia”). Raw export contents The raw eye-tracking exports include: continuous pupil diameter recordings (right eye, mm) gaze coordinates fixation and saccade information trial timing variables participant pseudonyms video/trial identifiers AOI-related variables tracking quality information The files are original export files from BeGaze eye-tracking software Anonymization All participant identifiers were pseudonymized prior to release. No directly identifying information is included in the shared exports. Purpose of raw data sharing The raw exports are shared to support reproducibility of preprocessing steps and replication of pupil preprocessing and baseline correction Relation to processed datasets The processed long-format datasets included elsewhere in this repository were derived from these raw exports using the provided R preprocessing scripts. Processing steps included: baseline pupil calculation baseline correction aggregation into 5-second time bins filtering of low-sample bins creation of repeated-measures long-format analysis tables
