Final answer:
Empathy led to a willingness to trade places.
Step-by-step explanation:
In the study conducted by Baston and his colleagues (1981), university women were asked to watch another woman suffer a series of painful shocks. Some participants were led to feel empathy for the woman and were then asked if they would be willing to trade places with her and take the remaining shocks. The results of the study indicated that empathy led to a willingness to trade places, suggesting that empathy can increase one's willingness to help.
