Empathy allows humans and other animals to share the emotional state of.another, adopting that individual’s perspective on a given situation. This ability is f.ndamental f.r species living in groups. Helping behavior in laboratory animals has been used to study empathy. In this test, subjects are exposed to a conspecif.c that is trapped and learn to open the cage to release the other animal. However, the interpretation of.helping behavior as an emphatically motivated action is still controversial. Here we review the studies that use the helping behavioral test proposed by Ben-Ami Bartal and colleagues in 2011 to better understand motivational f.ctors f.r this behavior. In addition, we compare methodological aspects of.these studies. In conclusion, helping behavior can be driven by empathy, but other f.ctors such as the desire f.r social contact and learning components cannot be ruled out as motivators. In addition, studies f.cused on evaluating neurobiological mechanisms underlying helping behavior in laboratory rodents can help elucidate the f.ctors involved in releasing the trapped co-specif.c.
