Wiki Version:
<p>2014 update: Data had been analyzed in R, but is being reproduced in an IPython Notebook: <a href="https://github.com/meli-lewis/rp_hajcak-foti/blob/master/RP_Hajcak_Foti.ipynb" rel="nofollow">https://github.com/meli-lewis/rp_hajcak-foti/blob/master/RP_Hajcak_Foti.ipynb</a></p> <p>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.</p> <p>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.</p> <p>See the project page for more details on the experiment, including the IVs and DVs listed below. Here is what they mean:</p> <ul> <li><strong>participant</strong>: the number assigned to a given participant</li> <li><strong>gender</strong>: 0 = male, 1 = female</li> <li><strong>ERN</strong>: 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.</li> <li><strong>EPS</strong>: 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.</li> <li><strong>errors</strong>: ints for how many errors were made during the experiment</li> <li><strong>startle_type</strong>: strings describing what type of trial the data under "startle" is aggregated from. See project page for details.</li> <li><strong>startle</strong>: floats for magnitude of startle response by trial type, not calculated as in the EPS.</li> <li><strong>startle_peak</strong>: ints for time in milliseconds following presentation of auditory stimulus that peak magnitude of startle response was reached.</li> </ul>
