2014 update: Data had been analyzed in R, but is being reproduced in an IPython Notebook: https://github.com/meli-lewis/rp_hajcak-foti/blob/master/RP_Hajcak_Foti.ipynb 2015 update: text files are of ERPs for every electrode site for error (_Inc) and correct (_Cor) trials, the difference of which (at electrode site 2) produces the ERN used for the main finding. The file "collaboration.csv" is the combined ERN and EPS data from the original and replication studies, made possible through collaboration with the original authors. See the project page for more details on the experiment, including the IVs and DVs listed below. Here is what they mean: - **participant**: the number assigned to a given participant - **gender**: 0 = male, 1 = female - **ERN**: floats for area under curve from 0-100ms, meant to describe the amplitude of the error-related negativity. The ERN is the difference between ERPs on correct trials and ERPs on error trials. See paper for more information. - **EPS**: floats for area under curve from 20-120ms, meant to describe the magnitude of startle response following errors minus startle response not following errors. See paper for more information. - **errors**: ints for how many errors were made during the experiment - **startle_type**: strings describing what type of trial the data under "startle" is aggregated from. See project page for details. - **startle**: floats for magnitude of startle response by trial type, not calculated as in the EPS. - **startle_peak**: ints for time in milliseconds following presentation of auditory stimulus that peak magnitude of startle response was reached.
