The Textbook Describes a Study Conducted by Nancy Eisenberg and Colleagues

The textbook describes a study conducted by Nancy Eisenberg and colleagues that examined if a distinct physiological signature exists that predicts whether a person will act altruistically.Participants watched a videotape of a woman and children who had been in an accident.The children were forced to miss school while they recovered in the hospital.While participants watched this tape, their facial expressions were recorded.Finally, participants were asked if they would be willing to help by taking homework to the injured children in the hospital.What did the results of this study suggest about predicting altruism through recording facial expressions?

A) There was no relationship between participants' facial expressions and their willingness to help.
B) Participants who showed a concerned gaze and a slowing of their heart rate were more willing to help.
C) Participants who showed a painful wince in the face and an increased heart rate were more willing to help.
D) Participants who frowned were more likely to help compared to those who smiled.
