Investigating fNIRS Test-Retest Reliability During Lexical Decision
Listed in Borealis
Data and analysis code accompanying the associated preprint (full citation under Related Publication).
Description
The study assessed the test-retest reliability of the functional near-infrared spectroscopy (fNIRS) signal during a lexical decision task. Thirty English-speaking adults completed the task during fNIRS recording in two sessions approximately one week apart, supporting four reading contrasts (print tuning, sublexical tuning, and coarse and fine lexical tuning) across ten bilateral regions of interest.
Contents. The dataset is organized according to the Brain Imaging Data Structure (BIDS version 1.9.0) and validates with no errors. It contains raw fNIRS recordings (SNIRF) and trial-level behavioural data for 30 participants across two sessions; processed derivatives (first- and second-level GLM results, test-retest reliability/ICC results, and behavioural and questionnaire summaries); and the full analysis code as Jupyter notebooks.

Conditions of use — please read before downloading. These data are shared under Dalhousie University Social Sciences and Humanities Research Ethics Board approval #2023-6928. All data are provided for the purposes of reproducibility, transparency, verification, and/or error detection.
Participants sub-012 and sub-022 did not consent to future, unspecified research use, and their data must not be used for any new or secondary analysis; all other participants did consent to such use. Per-participant status is recorded machine-readably in participants.tsv (the future_use_consent column), so these two participants can be filtered programmatically. If you reuse these data for a new analysis, you must exclude sub-012 and sub-022.
Individual-level demographic variables (age, sex, and language background) are not included, per the participant consent; they are reported only at the group level in the README. Acquisition dates and times have been removed throughout, and raw source material is not included. See README.md for full documentation of the dataset structure, acquisition parameters, and group-level participant characteristics, and TERMS.txt for the complete terms of use.
