摘要: The study of inequity aversion in animals debuted with a report the behaviour capuchin monkeys (Cebus apella). This generated many debates following number criticisms. Ultimately, however, finding stimulated widespread interest, and multiple studies have since attempted to demonstrate various other non-human animal species, positive results addition which no response was found. Domestic dogs represent an interesting case as, unlike primates, they do not respond negatively reward quality but do, being unrewarded presence rewarded partner. Numerous been published on recent years. Combining three tasks seven peer-reviewed publications, over 140 individual tested experiments. Consequently, are one best studied species this field could offer insights into species. In review, we summarise critically evaluate current evidence for dogs. Additionally, provide comprehensive discussion two understudied aspects aversion, underlying mechanisms ultimate function, drawing latest findings these topics while also placing developments context what is known, or thought be case, Finally, highlight gaps our understanding thereby identify potential avenues future research area.
