Ample research demonstrated that empathizing with someone in need promotes helping that person. Two studies examined whether this effect of empathy on helping behavior holds across different emotional reactions expressed by a target in need. Results of Study 1 indicate that perspective taking with a sad needy target increased empathic concern which, in turn, fostered helping the individual. This relation was not found for participants taking the perspective of angry or disgusted needy targets. Study 2 provides further support for the underlying mechanism of the results of Study 1. Perspective taking with a sad needy target increased empathizers' empathic concern because perception of target neediness was increased. Again, this pattern was not found for perspective taking with an angry needy target. The findings correspond to theorizing on the role of emotions in person perception. Hence, the current research provides insights regarding the boundary conditions of the empathy-helping association.
