This dataset includes skin conductance response (SCR) measurement, keypress responses and keypress response times to stimuli drawn from the International Affective Picture System for each of 24 healthy unmedicated participants (12 males and 12 females aged 27+/-4.6 years). The experiment used a 2x3 factorial design with the factors picture type (aversive, neutral), and mean ISI (3s, 9s, and 19s). Data are untrimmed. The referenced article used a trimmed version of the data (trim points: 0.5 s before first marker until 20 s after last marker). This detail is not mentioned in the methods section of the paper. See the readme file for more detail. Data are stored as .mat files for use with MATLAB in a format readable by the PsPM toolbox (pspm.sourceforge.net).
