(Working) Memory (Janczyk and Liesefeld)
Our memory-psychological work concerns selection processes in working memory as well as knowledge retrieval from long-term memory.
(Visual) Working memory
Working memory is a key component of human cognition and recent years have witnessed most extensive empirical, theoretical, and methodological progress in the visual domain. One central question in models of visual working memory (VWM) is how certain, already encoded, VWM contents are selected and what happens to them when they are no longer relevant. For example, Markus Janczyk has investigated the extent to which selection is bound to limited resources and to what extent later cues (so-called retro cues) still favor selection in VWM. Heinrich Liesefeld is interested in how priority-map mechanisms (including object saliency) influences VWM (encoding) and how this precious limited storage space can be kept free of irrelevant (distracting) information (see Research – Visual attention for further details).

Knowledge retrieval and language modality
In the context of e.g. tests or eyewitness reports, speech production is used as a window to a person's knowledge. In general, however, answers or statements can be given orally or in writing, and the question arises as to the equivalence of both modalities with regard to the validity of the knowledge acquisition. Based on theoretical assumptions that speak in favor of the written modality, we have begun to systematically examine this question. This work will be done in cooperation with Prof. Dr. med. Joachim Grabowski (Hannover).
