Measurement of Cognitive Load in Accordance with Listening and Observation for Writing Tasks Using Galvanic Skin Response

Bachelor Thesis , 2019 , 41 Pages

Medicine - Biomedical Engineering

The galvanic skin response alludes to changes in perspiration organ movement that are intelligent of the power of our passionate state, also called enthusiastic excitement. it has normally been explored through single or few measures and in one exploratory situation. Galvanic Skin Response (GSR) has as of late stood out for researchers as a planned physiological marker of intellectual feelings. In this exploration, intending to play out a far reaching study, we have evaluated GSR information capture for fifteen writing task and three difficulty levels and determined time and frequency domain feature. We determined that cognitive load is proportional to the task difficulty level. If cognitive load increases, task difficulty level will increase. If cognitive load decreases, task difficulty level will decrease.
