Data Processing
Smoothing
The raw electrodermal activity (EDA) signal is smoothed with an exponential smoothing function in matlab to remove high frequency noise (exp_smooth.m, alpha = 0.05).
Before:
After:
For calculating synchronization, I also removed the low frequency signals. See the couples section for methodology.
Sections
The dancing alone and dancing with partner sections are extracted from each participant’s EDA signal. Each section is further divided by song for more detailed analysis.
