“…Drawing from research on “media ecology” or “media environment,” pioneered by McLuhan’s influential idea of “The Medium is the Message” (McLuhan & Fiore, 1967), we posit that different media have distinct physical, psychological, and social features, and thus differ in their influence on people’s perceptions and behavior (Meyrowitz, 1994). Past research found that using one medium versus another can affect processes such as persuasiveness (e.g., Marshall & WoonBong, 2003; Worchel et al, 1975), affect (e.g., Simons et al, 1999), resistance to change (e.g., Goodman & Truss, 2004), and learning (e.g., Garland & Loranger, 1996). We theorize that offering information through personal media (e.g., leaflets, smartphones) has different effects from offering the same information through public media (e.g., posters, overheads).…”
