%T Kognitionspsychologische Untersuchungen eines Rechenk?nstlers
%X A detailed analysis of the processes of a mental calculator (Gert Mittring) is given in this paper. It shows that seemingly exceptional tasks (e.g., mentally extracting the 137. root from a number with thousand figures within less than 20 seconds) can be described in the frame of conventional cognitive processes.
