Rhesus monkeys, Macaca mulatta, on the island of Cayo Santiago, Puerto Rico produce one or more of five acoustically distinctive calls when they find food. Three of these calls ('warbles', 'harmonic arches' and 'chirps') are produced by individuals finding high-quality, rare food items, whereas the other two calls ('coos' and 'grunts') are produced upon encountering lower-quality, common food items, and in non-food contexts as well. To determine how rhesus classify such acoustic variation, I… Expand
Functional referents and acoustic similarity revisited: the case of Barbary macaque alarm calls
Abstract. Barbary macaques (Macaca sylvanus) utter "shrill barks" in response to disturbances in their surroundings. In some cases, the majority of group members react by running away or climbing upExpand

Results showed that monkeys used the semantic information conveyed by the Campbell's alarm calls to predict the presence of a predator, consistent with the hypothesis that non–human primates are able to use acoustic signals of diverse origin as labels for underlying mental representations. Expand
Is acoustic evaluation in a non-primate mammal, the tree shrew, affected by context?
New findings provided first evidence that in non-primate mammals acoustic evaluation is not solely affected by the sound-associated context but is also linked to unusualness and acoustic cues, such as peak frequency. Expand
Functionally Referential Communication in a Chimpanzee
Experimental evidence is provided that the authors' closest living relatives can produce and understand functionally referential calls as part of their natural communication and it is suggested that these findings give support to the vocal rather than gestural theories of language evolution. Expand
Discrete or graded variation within rhesus monkey screams? Psychophysical experiments on classification
Abstract Gouzoules et al. (1984, Animal Behaviour, 32 , 182–193) presented evidence that semifree-ranging rhesus monkeys, Macaca mulatta , produce acoustically distinctive classes of screamExpand
The Role of Temporal Cues in Rhesus Monkey Vocal Recognition: Orienting Asymmetries to Reversed Calls
It is suggested that for at least a subset of calls, rhesus macaques use temporal cues to recognize conspecific vocal signals and the asymmetry of the behavioral response, and the corresponding asymmetry in the time-amplitude waveform, may have important implications for studies of temporal coding in the primate auditory system.

‘The bone is mine’: affective and referential aspects of dog growls
A number of species are considered to use functionally referential signals such as alarm calls or food-related vocalizations. However, this particular function of communicative interaction has notExpand
Orienting asymmetries in rhesus monkeys: the effect of time-domain changes on acoustic perception
The orienting bias is interpreted as evidence that hemispheric asymmetries underly this perceptual effect, and for some call types within the rhesus repertoire, temporal properties such as interpulse interval provide significant information to listeners about whether the signal is from a conspecific or not.

The production and perception of long calls by cotton-top tamarins (Saguinus oedipus): acoustic analyses and playback experiments.
An asymmetry was revealed between the authors' acoustic analyses of individual identity and the tamarins' capacity to discriminate among vocal signatures; whereas all colony members have distinctive vocal signatures, it was found that not allTamarins were equally discriminable based on the habituation-dishabituation paradigm.

Optimal features for auditory categorization
This work demonstrates using an information-theoretic approach that production-invariant classification of calls can be achieved by detecting mid-level acoustic features and suggests that high-level neural representations of sounds are based on task-dependent features optimized for specific computational goals.

Food-associated calls in rhesus macaques (Macaca mulatta): I. Socioecological factors
Results from ali-day follows on adult males and adult females reveal that changes in hunger level influence call rate but not call type; the different call types are produced throughout the day. Expand
The role of articulation in the production of rhesus monkey, Macaca mulatta, vocalizations
Abstract Abstract. Many non-human primates have large and acoustically diverse vocal repertoires. However, our understanding of the phonatory mechanisms underlying such acoustic variation is poor.Expand
Rhesus monkey (Macaca mulatta) screams: Representational signalling in the recruitment of agonistic aid
Abstract Free-ranging rhesus monkeys on Cayo Santiago (Puerto Rico) give five acoustically distinct scream vocalizations during agonistic encounters. These calls are thought to be an importantExpand
Assessment of meaning and the detection of unreliable signals by vervet monkeys
Free-ranging vervet monkeys, Cercopithecus aethiops, who had learned to ignore playbacks of one type of call by an unreliable signaller subsequently also ignored playback of an acoustically differentExpand
Vocal recognition of individuals and kin in free-ranging rhesus monkeys
The social behaviour of many species of non-human primates suggests a capacity for both individual and kin recognition. In these species, the ability to signal and perceive identity at a distance mayExpand
Vervet monkey alarm calls: Semantic communication in a free-ranging primate
It is concluded that vervet alarm calls function to designate different classes of external danger, and context was not a systematic determinant of response. Expand
Food-associated calls correlate with food preferences in cotton-top tamarins
Abstract Food-associated calls in some birds and primates have been described as representational signals, with external reference to food objects. However, alternative interpretations suggest thatExpand
Toque macaque food calls: Semantic communication concerning food distribution in the environment
It is concluded that food calls are semantic signals (or symbols) that evoke the same response (rapid direct approach) as seeing the external referent of the calls (a source of abundant food) itself would. Expand
Left hemisphere dominance for processing vocalizations in adult, but not infant, rhesus monkeys: field experiments.

Like humans, adult rhesus monkeys also evidence left hemisphere dominance for processing species-specific vocalizations, however, the emergence of such asymmetry may depend on both differential maturation of the two hemispheres and experience with the species-typical vocal repertoire. Expand
Categorical Perception of Sound Frequency by Crickets
Categorical perception was tested in crickets by using two paradigms of human psychophysics, labeling and habituation-dishabituation, and the results show that crickets divide sound frequency categorically between attractive and repulsive sounds. Expand
