Phase 3b of the research will be a laboratory experiment that uses an experimental and analytic design that is parallel to that used in Phase 3a, the online experiment. The primary objective of Phase 3b is to assess physiological response (i.e., eye tracking) to different message appeals of the audio-visual messages used in Phase 3a on respondents' behavioral intentions and UV-related behavioral choices post-exposure. Including time for preparation, viewing, and removal of the monitoring equipment, the message viewing session will take about 45 minutes per session.
