Data are presented as mean ± standard deviation; means were compared by t-test if data were normally distributed, and Mann -Whitney U test if not; KEKS, short body perception questionnaire; KEKS-ill, illusory body perception; heart rate in beats per minute; CA, cardioceptive accuracy according to the Schandry paradigm and the Whitehead heartbeat discrimination task; in parentheses the scores of the training trial of the Whitehead task.
