Open data: Frequency mismatch negativity and visual load

Wiens, S., van Berlekom, E., Szychowska, M., & Eklund, R. (2019). Visual Perceptual Load Does Not Affect the Frequency Mismatch Negativity. Frontiers in Psychology, 10(1970). doi:10.3389/fpsyg.2019.01970

We manipulated visual perceptual load (high and low load) while we recorded electroencephalography. Event-related potentials (ERPs) were computed from these data.

OSF_*.pdf contains the preregistration at open science framework (osf). contains the raw eeg data files that were recorded with a biosemi system ( The files can be opened in matlab with the fieldtrip toolbox. contains all the matlab scripts that were used to process the ERP data with the toolbox fieldtrip.

ERP_2019_fieldtrip_mat_*.zip contain the final, preprocessed individual data files. They can be opened with matlab. contains the python scripts for the main task. They need python ( and psychopy ( contains the R scripts to process the working memory capacity (wmc) data. contains the R scripts to analyze the data and the output files with figures (eg scatterplots).
