Head-motion data from the 2018 Championship of Standstill (8 March 2018, University of Oslo): 112 participants (87 retained after marker-occlusion screening) in 13 groups stood as still as possible for 500 s while exposed to six 45-s audio stimuli (EDM excerpts, a custom rhythm, and a metronome) interleaved with silence. Qualisys infrared motion capture at 200 Hz (millimetres). Underlies the fractality (DFA) analysis of Gonzalez-Sanchez, Zelechowska & Jensenius (2019), Journal of Motor Behavior. Includes the two custom CC BY audio tracks (Metronome, Rhythm); the four commercial music excerpts are withheld, since they are copyrighted, with their acoustic features and spectrograms included as a redistributable stand-in.Formats. tab-separated text (.tsv) and PNG images. Column dictionaries named *_dictionary.tsv define the columns, and the README describes any table that has none. Funding.
