Figure 1.

(a to c) The Three Different Movement Alignment Levels of the Social Entrainment Video Paradigm in Study 1. Participants Imagined That They Are the Black Figure and That the Blue Figure Represents an Unknown Other Person. (d and e) Frequency Spectra of the Note-Onset Interval Series of the Music and Metronome Stimuli Detected by mironsets in the MIR Toolbox (Lartillot & Toiviainen, 2007) for MATLAB (MathWorks, Natick, MA). The Dashed Gray Line Represents the Beat of the Audio Stimuli and the Temporally Aligned Step Frequency of the Visual Stimuli, Which Was 94 bpm/638 ms. The Temporally Misaligned Step Frequency Was 80 bpm/750 ms. (f) Adapted Inclusion of Other in the Self Scale (Aron et al., 1992).
