How could knowing a child’s electrodermal activity (EDA) during therapy change occupational therapy practices? As a joint project between the MIT Media Lab and the Sensory Processing Disorder Foundation, we measured the EDA responses of 22 children participating in occupational therapy for 77 hours. We saw children lying in a ball pit and their EDA correspondingly decreasing; we saw children’s EDA rapidly increase while they were swinging; and we saw many other patterns of responses from different therapeutic activities. Could we show how different guided activities changed children’s arousal with a statistical test? Analysis suggests that many factors play a role in changing children’s EDA, and these factors could not all be taken into account with our low sample size – making any statistical analysis inconclusive. As more tools begin to measure physiological data over longer periods of time, in less controlled settings, we should not forget to build a base understanding at the individual case level.
