Table 1.

Mean (SD) values for all the dependent measures. Behavioral variables (Physical Startle and Emotional Distress) are mean ratings of the intensity of the startle reaction and emotional distress coded by observers. Skin Conductance (SC) variables represent mean response amplitudes in microsiemens (μs). F-statistic represents the significance of the linear pattern of the variable across clap trials using mixed model regressions with time of clap as the independent variable
