  • Approach behavior is measured as number of button presses. Self-reported attraction is measured on a 7-point visual scale (please see main text).

  • * Significant differences between pre- and postobservation values (P < 0.05, two-tailed. Level of interpersonal attraction, df = 39 in experiment I, df = 51 in experiment II. Interindividual variability, df = 5 in both experiments).
