The subjective discomfort was measured by setting the inconvenience level while taking the tests as a 7 according to the Likert scale.

The result showed that the ADHD tendency group showed higher Skin Conductance Level on the stress circumstances. They maintained the high level during rest phase. Also, the group showed higher subjective discomforted level.
