Lo que parece un simple instinto puede ser razonamiento más flexible.

Accumulated experience may facilitate the formation of relational rules that can be applied in novel contexts. However, the extent to which animals can form a relational rule, and are able to apply it to novel contexts remains a core focus when understanding the evolution of cognition. Here, we assessed the ability of African grey parrots o acquire the relative larger-than rule in size or quantity discrimination, and if so, how this was learned. Eight captive parrots initially participated in a natural preference test (NPT) to assess their prior preference for a larger amoun","pubDate":"2026-10-24","url":"https://www.biorxiv.org/content/10.64898/2026.10.19.760036v1?rss=1"},"indexado":"2026-10-24T13:11:28.041Z"}}
