This study examined how lecture background type influences student learning experiences in business and professional communication contexts. An online experiment was conducted with undergraduate students in the United States. Participants viewed a lecture on one-way interviews presented with either a digitally created background (university-branded PowerPoint slide) or authentic-appearing background (image of a physical office wall). The results revealed an indirect effect of lecture background type on students’ perceptions, mediated by the perceived social presence of the instructor: specifically, a lecture delivered with an authentic-appearing background fostered social presence, which in turn, enhanced students’ perceptions of the instructor’s credibility and their affective learning.
