Video clips and discrimination tasks of experiments 1 and 2.

<p>Both experiments used the same 3 different video clips: baseline (top), light (middle) and heavy (bottom). Movement observation was presented together with an auditory discrimination task (<b>A</b>, experiment 1) or a visual discrimination task (<b>B</b>, experiment 2). The six different video sequences presented here represent one single trial with duration of 7 sec each. <b>A</b> In experiment 1, subjects had to discriminate two series of tones such that the position of one longer inter-tone-interval could either be identical (<b>A,</b> top) or different (<b>A</b>, middle). B In experiment 2, subjects had to discriminate to series of color changes of the rim. One of these colors was shown longer (as indicated by wider rectangles), however, the rhythm of the color change could either be identical (<b>B</b>, top) or different (<b>B</b>, middle). In both experiments, subjects had to say “yes” when the two series of tones/colors were identical, “no” when they were not identical, and “pass” when no decision could be made. The verbal response was provided after the video clip had finished. TMS was applied in between the two series of tone, when the object was lifted in the air, as symbolized by the TMS coil.
