Closer to the Heart, Closer to the Mind: Using Psychological Distance to Communicate a Measles Outbreak.

Psychological distance can influence a variety of risk-related perceptions and behaviors. This study (N = 205) examines the effect of spatial distance manipulation on emotions, risk perception, and behavioral intention following a recent measles outbreak in the United States. Results indicate that experimentally induced spatial distance influences emotional intensity, which affects psychological distance perception. Perceived distance subsequently influences risk perception, while emotions influence information engagement and support for mandatory vaccination.
