Lifespan development of executive functions
We are interested in the lifespan development of cognitive functions, particularly in the domain of executive control that includes abilities such as maintenance and selection of task relevant information, inhibition of prepotent response tendencies, and switching between tasks. Previous studies have shown that these control functions develop multidimensionally and multidirectionally across the human lifespan. Our lab investigates whether age-differences in executive control can be modulated, for instance by means of verbal strategies or task practice.

Teacher education
In a longitudinal approach, we investigate the role of individual and organizational variables on academic success in teacher candidates. Our focus is on multiple criteria of success, among them knowledge in educational science, didactics, and teaching competence.

Psychocardiology
Patients with chronic heart failure not only suffer from physical symptoms but also display distinct cognitive deficits, particularly in the domains of executive function, memory, and processing speed. These deficits can seriously impair compliance and health management. In our research we investigate the extent of cognitive deficits, the potential of cognitive training to compensate them as well as the psychological well being of patients suffering from chronic heart failure.

Cognitive plasticity across the lifespan
In our daily lives, we are constantly required to adapt to the demands of changing developmental contexts and dynamic social environments. The potential modifiability of a person’s cognitive and neural processes resulting from these adaptations has been referred to as plasticity. One way to understand plasticity is to apply training interventions and to measure their effects in trained and untrained tasks. The work of our lab is focused on the effects of executive control training and working memory training in children, younger adults and older adults. Recently, we have been particularly interested in the effects of cognitive training in clinical populations (e.g., children suffering from ADHD) as well as on the effects of cognitive training on activities of daily living outside of the lab (e.g., academic achievement).
