The visual environment of biological organisms is mostly made of opaque objects that may well overlap and partly hide each other. In our visual experience, however, when an object is partially concealed by an obstacle, we do not perceive only the pieces or fragments of that object: the parts that are directly visible usually suffice for recognition of the whole object, a process dubbed “amodal completion” (4, 7). Studies on animals indicate that both mammals (1, 8, 5, 10) and birds (2, 3, 6, 9) do seem to experience completion of partly occluded objects. This could reflect convergent evolution. Alternatively, it could be that mechanisms of amodal completion are widespread among vertebrates. Here we investigated whether fish complete partly occluded objects.

Abstract
The visual environment of biological organisms is mostly made of opaque objects that may well overlap and partly hide each other. In our visual experience, however, when an object is partially concealed by an obstacle, we do not perceive only the pieces or fragments of that object: the parts that are directly visible usually suffice for recognition of the whole object, a process dubbed “amodal completion” (4, 7). Studies on animals indicate that both mammals (1, 8, 5, 10) and birds (2, 3, 6, 9) do seem to experience completion of partly occluded objects. This could reflect convergent evolution. Alternatively, it could be that mechanisms of amodal completion are widespread among vertebrates. Here we investigated whether fish complete partly occluded objects.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
