Congratulations: Philipp Sprengholz successfully completes PhD
On May 11, 2022, Philipp Sprengholz successfully defended his dissertation entitled "Of sticks and carrots: Effects of coercive and rewarding measures for increasing vaccination uptake" (supervised by Prof. Cornelia Betsch) at the Faculty of Education.
Philipp Sprengholz studied psychology in Hagen and Jena and received his Master of Science in cognitive psychology and cognitive neuroscience from the Friedrich Schiller University Jena in 2018.
In his dissertation project, he examined ways to increase the vaccination rate against COVID-19 in the context of the SARS-CoV2 pandemic, focusing in particular on compulsory vaccination and financial incentives. He examines boundary conditions and psychological consequences - such as the question of what behavioral consequences political framework conditions have.
We warmly congratulate him on passing his doctorate and the outstanding scientific achievement!
