Annabell Halfmann is a Ph.D.-scholarship holder of the German Academic Scholarship Foundation (“Studienstiftung des deutschen Volkes”) and an academic staff member at the chair of Prof. Peter Vorderer. Prior to that, she graduated with a bachelor’s degree in communication management and a master’s degree in media and communication studies with the elective subject media psychology. Her main areas of research concern media selection, processes, and effects. In particular, she examines the influence of social norms on media use and effects, the influence of the phenomenon “permanently online, permanently connected” on media users’ well-being as well as the exposure to and effects of entertainment media. Her doctoral thesis addresses the questions of why individuals frequently fail to exert self-control over their mediated communication use and how this affects feelings of guilt and their overall well-being. Ms. Halfmann holds seminars for BA and MA students that focus on communication theories and quantitative methods (e.g. experimental research designs). Furthermore, she is responsible for the approval of courses.
