Procedure 1: Skin Conductance (GSSR)

Skin conductance setup was followed according to LabChart Student Protocol for “Psychophysiology” from sections “Equipment Setup and Equipment Calibration” to “Exercise 1: Skin conductance and the startle response” Only step 1 from Exercise 1: Skin conductance and the startle response were followed. Readings were taken throughout the six-minute video-watching period. 

Procedure 2: Electrooculography (EOG)

 Electrooculography setup was followed according to LabChart Student Protocol for “Electrooculography” from sections “Equipment Setup and Electrode Attachment” to “Exercise 1: EOG Artifacts”. Once those sections were complete, the participant's gaze was calibrated and the control and lecture videos were shown in the appropriate order \cite{service}. In order to obtain the data, the subject sat in a chair 18 inches from the screen. Recording was started and the volunteer shifted their gaze from one side of the computer screen to the other multiple times and stopped in the middle of the screen.  Once completed, recording was stopped.  The portion corresponding to the volunteer's gaze left and right was selected. The amplitude scale was adjusted according to the subject's gaze assuming the center was 0%. Data varying -50% or lower and 50% or higher were considered off-screen. Once this was set up, the student watched the control video. This was repeated with each lecture type.
