Blood Pressure
An Omron BP 742 blood pressure cuff was used in this study. The cuff was placed on the participant's left arm that did not have the finger pulse transducer or GSR. The cuff was placed at the beginning of the testing, before any videos were shown, and was left on throughout the test. Before showing any videos, a baseline blood pressure reading was taken. For each video, readings were taken one minute after the start and one minute before the end.
The blood pressure cuff was activated by manually pressing the 'start' button on the cuff's attached computer and interface. After measuring pressure, the interface displayed systolic and diastolic blood pressures as well as heart rate. Once the information was displayed, the interface remained on, but was no longer inflated so it was not squeezing the participant. As information was displayed by the cuff's interface, it was input into Google Sheets for data storage.
