We have argued for a balanced perspective on the relative benefits and costs of approach and avoidance motivation, and that thinking hierarchically about these motives contributes to a better understanding of goal pursuit. Having received several scholarly commentaries on these primary claims, in this reply, we further clarify the roles of regulatory fit and intelligibility in goal pursuit, examine surviving and thriving at different levels of the motivational hierarchy, and demonstrate that thinking hierarchically about approach and avoidance motivation provides a wealth of opportunities for additional research into the dynamics of motivation.

In social species, groups and their members face a variety of threats from conspecific outsiders. Such out-group conflict is predicted to influence within-group behavior, with empirical work demonstrating this link in humans, primates, and birds. In our note “Out-Group Threat Promotes Within-Group Affiliation in a Cooperative Fish,” appearing in The American Naturalist in February 2016, we provided experimental evidence that simulated territorial intrusions result in subsequent increases in affiliation among groupmates in a cichlid fish (Neolamprologus pulcher). Martin Kavaliers and Elena Choleris, in their comment “Out-Group Threat Responses, In-Group Bias, and Nonapeptide Involvement Are Conserved Across Vertebrates,” appearing in this issue, commented on our cichlid-fish article; they consider the conserved nature of the link between out-group threat and in-group behavior and bias in vertebrates, the influence of pathogens in the process, and the potential underpinning hormonal mechanisms. Here, we provide clarification and expansion of some of the core points that are discussed in the comment by Kavaliers and Choleris.
