Processing of biological motion point-light displays by baboons (Papio papio).
Humans apply complex conceptual judgments to point-light displays (PLDs) representing biological motion (BM), but how animals process this kind of display remains uncertain. Four baboons (Papio papio) were trained to discriminate BM from nonbiological motion PLDs using an operant computerized test system. Transfer tests were given after training with novel BM stimuli representing humans or babo...
متن کاملOrangutans (Pongo spp.) have deeper, more efficient sleep than baboons (Papio papio) in captivity.
The nightly construction of arboreal sleeping platforms or "nests" has been observed among every great ape population studied to date. However, this behavior has never been reported in any other nonhuman primate and comparisons between ape and monkey sleep illuminate the link between sleeping substrates, positional behavior, and sleep efficiency. Here, we compare sleep depth and efficiency and ...
متن کاملOrthographic processing in baboons (Papio papio).
Skilled readers use information about which letters are where in a word (orthographic information) in order to access the sounds and meanings of printed words. We asked whether efficient processing of orthographic information could be achieved in the absence of prior language knowledge. To do so, we trained baboons to discriminate English words from nonsense combinations of letters that resembl...
متن کاملPerception of the corridor illusion by baboons (Papio papio).
The corridor illusion was assessed in four baboons (Papio papio) by way of judgmental task implying a comparison between the size of two figures presented on various backgrounds. Findings demonstrate that the baboons are sensitive to the corridor illusion.
متن کاملIntestinal spirochaetosis.
Two cases of intestinal spirochaetosis are described. The first case improved with treatment while the second case improved spontaneously without any intervention. Controversy over treatment and pathogenicity of intestinal spirochaetosis is discussed with review of previous publications.
