 While it is conceptually necessary to differentiate between these various emotional responses, it has to be admitted that it is empirically not very easy to discriminate between them, since they tend to occur together. Think or imagine yourself attending the funeral of the child of a friend or good acquaintance. This is probably one reason why early researchers tended not to distinguish between the above aspects in their study of empathy related phenomena. Yet since the above distinctions refer to very different psychological mechanisms, it is absolutely central to distinguish between them when empirically assessing the impact and contribution of empathy to an agent’s pro-social motivation and behavior. Given the ambiguity of the empathy concept within psychology—particularly in the earlier literature—in evaluating and comparing different empirical empathy studies, it is always crucial to keep in mind how empathy has been defined and measured within the context of these studies.
