Psychology begins with critical thinking

Psychology is still a young science. You won’t get very far by simply memorising key facts. The knowledge gained during your degree may soon be out of date. At the same time, scientific claims to knowledge compete with the everyday intuitive insights we gather, as well as the narratives and interpretations presented to us by the media. That is why, as a psychologist, it is particularly important to be able to critically assess and contextualise evidence and studies.

In our teaching, we impart the tools of critical thinking and encourage discussion. We explore the weaknesses in the acquisition of psychological knowledge, conduct research on research itself, and develop tools to carry out better research. In terms of content, we focus primarily on observational, non-experimental data at the interface between psychology and biology. In terms of policy, we advocate for greater transparency in research and a more open culture of acknowledging mistakes.

research

A key focus of our research is meta-science – in other words, research about research.

In our research into methodology, we focus primarily on the pitfalls and strengths of common measurement methods, ranging from subjective self-assessments to steroids in saliva. Only by understanding the limitations of our measurement tools and modelling them statistically correctly can we gain reliable insights into the underlying reality.

We also develop tools to improve data collection anddocumentation.

The main focus of our research is on individual differences at the disciplinary boundary between psychology and biology. In particular, individual differences in hormonal fluctuations across the menstrual cycle, as well as the associated differences in the effects of hormonal contraception, are current research topics.
