Data availability
All EEG datasets, materials, and analysis codes from SPN research at the
University of Liverpool are housed in the Complete Liverpool SPN
catalogue on Open Science Framework (https://osf.io/2sncj/). As
described in Makin et al. (2022), the SPN catalogue has folders for each
SPN project. The pilot study is project 26 and new study is project 43.
This catalogue is designed for maximum transparency. Other researchers
could assess computational reproducibility by running an alternative
analysis. They could also use raw data for a new analysis (e.g., changes
in pre-stimulus alpha power when intoxicated). Materials to double check
the statistical tests reported in the results section (such as SPSS
files and R codes) are in subfolder called ‘Results and analysis in
Karakashevska et al.)’. Supplementary materials 1 is also in here.
