**Overview**
To validate and assess the reliability of an online behavioural laterality battery, 392 participants completed the a range of tasks twice.
This was pre-registered on the OSF: https://osf.io/fktmh
We report that high reliability was observed for a dichotic listening, chimeirc faces, and finger tapping task. We also report a rhyme decision visual half-field task for which the reliability was less satisfactory. Thus, we are actively developing the rhyme task.
**Materials**
The materials required to run each task can be found in the *Materials* folder. It includes the spreadsheets required to run the task via Gorilla.sc.
**Data**
All (anonymised) can be found under the the *Reliability_300subjects* folder.
The following files are outputted from Gorilla.sc:
- Demographics.csv
- Miles.csv
- Porta.csv
- EHI.csv
- LexTALE.csv
- day1_combined.csv
- day2_combined.csv
These are all required to run our pre-processing script.
The pre-processing script outputs:
- for_figs.csv
- allsum_out.csv
- LIsz0.csv
- LIsz1.csv
- LIsz2.csv
- LIs0.csv
- LIs1.csv
- LIs2.csv
These are used in the formal analysis scripts.
**Analysis scripts**
Two markdown scripts are available under *Analysis Scripts*.
The *battery_preprocessing_v6_DB_split2.Rmd* file pre-processing the data.
The *online_laterality_reliability.Rmd* script is used to analyse the data and write the manuscript.
**Tasks**
Running version of the dichotic listening, chimeric faces, and finger tapping tasks can be found at: https://gorilla.sc/openmaterials/104636
