dc.descriptionObject permanence, the ability to represent hidden objects, has not been extensively assessed in cetaceans and the available evidence is contradictory. Although bottlenose dolphins (Tursiops truncatus) are thought to be endowed with cognitive capacities required to pass complex object permanence tests, they have failed a series of tasks involving invisible displacements, which raises the question of whether they do master object permanence. Lack of understanding of containment or lack of experience tracking objects hidden from both sight and echolocation may explain such unexpected results. The goal of the current study was to test these two hypotheses in a series of visible and invisible displacement tasks with bottlenose dolphins. Our results suggest that dolphins are indeed able to succeed in complex object permanence tasks but only if they have previous visual experience with the movements of objects inside other objects. Thus, these outcomes point to an important role of visual experience in the development of object permanence skills.en-US
dc.descriptionLa permanencia de los objetos, la capacidad de representar objetos ocultos, no se ha evaluado ampliamente en los cetáceos y la evidencia disponible es contradictoria. Aunque se cree que los delfines nariz de botella (Tursiops truncatus) están dotados de las capacidades cognitivas necesarias para aprobar pruebas complejas de permanencia de objetos, han fallado en una serie de tareas que involucran desplazamientos invisibles, lo que plantea la cuestión de si logran la permanencia de los objetos maestros. La falta de comprensión de la contención o la falta de experiencia en el seguimiento de objetos ocultos tanto de la vista como de la ecolocación pueden explicar estos resultados inesperados. El objetivo del presente estudio fue probar estas dos hipótesis en una serie de tareas de desplazamiento visibles e invisibles con delfines nariz de botella. Nuestros resultados sugieren que los delfines pueden tener éxito en tareas complejas de permanencia de objetos, pero solo si tienen experiencia visual previa con los movimientos de objetos dentro de otros objetos. Por lo tanto, estos resultados apuntan a un papel importante de la experiencia visual en el desarrollo de habilidades de permanencia de
