Absence of SCRs

Absence of SCRs during events but unrelated SCR in the middle

If we run the SCR analysis on this subject’s data, we get one big massive SCR and otherwise nothing (until after the task ends). Remember to always cross-check other channels if strange events occur. In this case, we are also looking at the EMG signal (channel 11; muscle activity from the right forearm). You can see that there was muscle activity at the onset of the big SCR. We don’t know whether that was a big body movement, a sneeze, a cough, or a yawn or if the person got startled (e.g. unexpected noise, someone knocked on the door or similar → can always check for notes for this subject’s session on confluence). In any case, we need to exclude this subject from the analysis.

How do I know the data have sufficient quality to analyze?
