Abstract
The aim of this paper is to introduce both Libet's experiments from 1980s, which were dealing with the issue of the free will, and their revision currently realized in the Department of Psychology at Palacky University Olomouc. Benjamin Libet found that specific electrical changes in brain measurable by electroencephalography (EEG) precede not only conscious experience of motion, but also a mere wish to move.
After their publication, the results of Libet's experiments provoked an intense debate about the existence of free will. Nowadays, 33 years after the first publication of the original experiment, this study is being reconstructed in the Department of Psychology in Olomouc using instruments for measuring bioelectrical signals.
The reconstruction of the complete Libet's study in the Czech Republic is a unique attempt to verify and comprehensively publish the results of the experiment. In addition to the replication, the article also presents preliminary results of an experiment which tested the validity of introspective components in Libet's methodology.
