Real donations, self-report, and psychophysiological measures of affect for 1, 2, and 8 children.
In Study 1, average donations (in SEK) decreased with increasing number of victims (A) and positive affect was stronger for the single victim (B). In Study 2, donations decreased with more victims (C) and positive affect (facial EMG measurement) decreased with an increasing number of victims (D). ZM activity for one child was significantly greater than for two children (p<0.05).
