Cognitive Functions

Research group „Cognitive Functions“

We investigate the cognitive and neural underpinnings of higher cognitive functions, such as planning abilities and working memory.

By employing the Tower of London test (ToL) we were able to identify differential and specific cognitive parameters and investigated their neural correlates in a series of imaging studies.

Planning and other higher cognitive functions operate on mental representations held in working memory. Thus, another research focus is basic working memory operations, such as mnemonic search for certain information or cognitive and neural underpinnings of attention shifts within working memory.

Besides behavioral experiments we use imaging techniques such as functional magnetic resonance imaging (fMRI) and magnetoencephalography (MEG).
