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.
