Vera Fahrner

External PhD candidate: Vera Fahrner from the DLR Institute of Transport Research in Berlin

This May, Vera Fahrner started her PhD project in our group. Her research focusses on the acceptance of different drive systems and energy sources in road transport in Germany. She is particularly interested in the "mental models" that people form of new technologies in road transport and, at the same time, how these can be appropriately assessed and changed in the future. Welcome, Vera!

New article on social inequality and political participation in youth in Political Psychology

Alexandra Zapko-Willmes' article "Accounting for the Association Between Socioeconomic Status and Youth Political Participation: A Twin Family Study" will be published in the journal Political Psychology. The article was written in collaboration with political scientist Yannis Theocharis (TU München).
The twin study investigated to what extent the association between socioeconomic status (particularly educational attainment) and political engagement of young people can be explained by personality characteristics and family factors. Results suggest that, depending on the form of political participation, the association is attributable to political interest, intelligence, and openness to experience.

Semester abroad in Iceland Island

Our student assistant Emma Kiesel has started her semester abroad in Iceland. She will live in Reykjavik and study psychology at Reykjavik University (RU) from August to December.

As a freemover, students can apply to any university worldwide that accepts them, but they often have to pay tuition fees and are not funded through the Erasmus program.
