Notes: For physiological reactivity, mean levels of individual channels (not corrected for baseline levels) and standard deviations (in parentheses) during the karaoke task. Higher values indicate greater physiological arousal for skin conductance, general somatic activity, systolic and diastolic blood pressure, respiration depth and finger temperature; lower values indicate greater physiological arousal for cardiac inter-beat interval, finger pulse amplitude, finger pulse transit time, ear pulse transit time, and respiration period. For behavioral reactivity, mean levels of self-conscious emotional behavior during the karaoke task. For abbreviations, see Table 1. *P < 0.10, **P < 0.05.
