TLDR
The results suggest that the basic mechanism for the identification of consonants in chimpanzees is similar to that in humans, although chimpanzees are less accurate than humans in discrimination of consonant.Abstract:
The perception of consonants which were followed by the vowel [a] was studied in chimpanzees and humans, using a reaction time task in which reaction times for discrimination of syllables were taken as an index of similarity between consonants. Consonants used were 20 natural French consonants and six natural and synthetic Japanese stop consonants. Cluster and MDSCAL analyses of reaction times for discrimination of the French consonants suggested that the manner of articulation is the major determinant of the structure of the perception of consonants by the chimpanzees. Discrimination of stop consonants suggested that the major grouping in the chimpanzees was by voicing. The place of articulation from the lips to the velum was reproduced only in the perception of the synthetic unvoiced stop consonants in the two dimensional MDSCAL space. The phoneme-boundary effect (categorical perception) for the voicing and place-of-articulation features was also examined by a chimpanzee using synthetic [ga]-[ka] and [ba]-[da] continua, respectively. The chimpanzee showed enhanced discriminability at or near the phonetic boundaries between the velar voiced and unvoiced and also between the voiced bilabial and alveolar stops. These results suggest that the basic mechanism for the identification of consonants in chimpanzees is similar to that in humans, although chimpanzees are less accurate than humans in discrimination of consonants.read more

Perception of complex geometric figures in chimpanzees (Pan troglodytes) and humans (Homo sapiens): analyses of visual similarity on the basis of choice reaction time.
TL;DR: The results suggested that chimpanzees and humans perceived the complex figures similarly and both species showed the same perceptual hierarchy or dominance among perceptual categories, as determined by the similarity of simple elements, on the basis of transformational invariances.

TL;DR: This paper examines the origins of language, as treated within Evolutionary Anthropology, under the light offered by a biolinguistic approach, and discusses ways in which to address these central issues, in an attempt to develop a collaborative approach to them.

Acquisition of auditory-visual intermodal matching-to-sample by a chimpanzee (Pan troglodytes): comparison with visual-visual intramodal matching
Kazuhide Hashiya,Shozo Kojima +1 more
TL;DR: The results show that the acquisition of AVMTS was facilitated by the alternation of auditory presentation and audio-visual presentation, and the subject showed rapid transfer of the performance to novel sets when the sound alone, but not the visual stimulus alone, served as the sample.

An analysis of perceptual confusions among some English consonants.
TL;DR: In this paper, an articulatory analysis of 16 English consonants was performed over voice communication systems with frequency distortion and with random masking noise. The listeners were forced to guess at every sound and a count was made of all the different errors that resulted when one sound was confused with another.

Teaching Sign Language to a Chimpanzee
TL;DR: The protein encoded by Nup160 directly interacts with that of another hybrid lethality gene, Nup96, indicating that at least two lethal hybrid incompatibility genes have evolved as byproducts of divergent coevolution among interacting components of the Drosophila nuclear pore complex.

Speech perception by the chinchilla: Identification functions for synthetic VOT stimuli
Patricia K. Kuhl,James D. Miller +1 more
TL;DR: The functions produced by the two species were very similar; the same relative locations of the phonetic boundaries, with lowest VOT boundaries for labial stimuli and highest for velar stimuli, were obtained for each animal and human subject.
