Our research is focused on statistical methods in psychological assessment. In particular this area includes methods for the analysis of data from psychometric achievement tests (such as mathematics in PISA or intelligence tests) or personality scales in cross-sectional and longitudinal studies.
The International Cognitive Ability Resource is a public-domain assessment tool which aims to encourage the broader assessment of cognitive abilities in psychology and other social sciences and facilitate neuropsychological assessment in medical research and practice. More than 100 qualified research groups from all over the world already use the instruments we developed and contribute to their ongoing revision and further development. The ICAR makes use of automatic item generation which yields test items with predictable psychometric properties. Find more on this technique and the possibility to use ICAR-items for your own research on the project's homepage.
As part of the DFG priority programme "Education as a Lifelong Process" (SPP 1646), we analyse longitudinal data from the National Educational Panel Study (NEPS). NEPS collects data particularly from children who have an increased risk of insufficient learning success compared to their peers, such as children with special educational needs or a migration background. The main aim of the planned analyses is to model the educational processes of these children, taking into account a number of possible protective factors. The comparability of test performance will also be investigated, which is an important precondition for the desired comparison of educational processes. Further information on the priority programme can be found here.
