Scream vocalizations of group-living rhesus macaques provoked by higher-ranking aggressors were examined in two contexts: encounters in which the rank difference between opponents was either large or small. Such vocalizations are important in eliciting support from the caller's allies in the group (usually matrilineal kin). Five acoustically distinct recruitment screams encode specific information about features of the agonistic context, for example, relative rank of the opponent and the… 
Agonistic screams differ among four species of macaques: the significance of motivation-structural rules
While the differences in the macaque species' vocalizations suggest no simple correlation between immediate context and the acoustic forms of screams, there was general correspondence between the acoustic structure predicted by motivation-structural rules and inferences about the internal state of the vocalizer derived from the typical intensity of aggressive patterns that characterize each of the four species.
The emotional canvas of human screams: patterns and acoustic cues in the perceptual categorization of a basic call type
It is found that acoustic variation in screams was associated with the perception of different emotions from these calls, and how listeners responded to 30 contextually diverse human screams on six different emotion prompts as well as how selected acoustic cues predicted these responses was investigated.
Affect cues in vocalizations of the bat, Megaderma lyra, during agonistic interactions.
Some features of emotional prosody in human speech may be traced back to affect cues in mammalian vocalizations. The present study addresses the question whether affect intensity, as expressed by the
Nonhuman primate alarm calls then and now
Against the background of the seminal papers on the vervet monkey alarm call system by Seyfarth, Cheney and Marler (1980a. 1980b), I provide an overview of context specificity in calling and call
Bioacoustic Monitoring of Aggression in Group-Housed Rhesus Macaques
Examination of the magnitude of aggression and the co-occurrence of certain vocalization types and aggression in 10 groups of rhesus macaques confirmed aggression as a significant problem in rhesu groups and indicated that certain patterns of vocalizations are indicative of the type or level of aggression.
Neurocognitive processing efficiency for non-alarm rather than alarm signaling in human scream calls
It is shown that scream calls are more diverse in their signaling and communicative nature in humans and that especially non-alarming screams, and positive screams in particular, seem to have higher efficiency in the cognitive, neural, and Communicative processing in humans.
Are the alarm calls of North American red squirrels (Tamiasciurus hudsonicus) functionally referential
Results indicated that squirrels registered and responded to alarm calls produced by others; however, their responses were not differentiated according to the type of alarm call they heard and, thus, did not provide evidence that the different alarm call variants hold any predator-specific, referential value.
Neurocognitive processing efficiency for discriminating human non-alarm rather than alarm scream calls
These findings show that scream calls are more diverse in their signaling and communicative nature in humans than previously assumed, and it is found that especially non-alarm screams, and positive screams in particular, seem to have higher efficiency in speeded discriminations and the implicit neural processing of various scream types in humans.
Brain activity underlying American crow processing of encounters with dead conspecifics
It is found that in response to observations of a dead crow, crows show significant activity in areas associated with higher-order decision-making (NCL), but not in Areas associated with social behaviors or fear learning, suggesting that crows might quickly learn from negative experiences.
Functions of multiple play signals in free-ranging juvenile rhesus macaques (Macaca mulatta)
Some mammals, including some nonhuman primates, use multiple play signals during social play that convey the playful mood or intention of the signaler. However, why single species use multiple play


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 important
Matrilineal signatures in the recruitment screams of pigtail macaques, Macaca nemestrina
In macaques and baboons, scream vocalizations play a major role in the recruitment of allies against agonistic opponents. Pigtail macaques make use of 4 acoustically distinct scream types, with each
Design features and developmental modification of pigtail macaque, Macaca nemestrina, agonistic screams
Scream vocalizations produced by pigtail macaques during agonistic encounters were studied using spectrographic and multivariate analyses. These calls are important in the recruitment of support from
Recruitment screams of pigtail monkeys (Macaca nemestrina) : ontogenetic perspectives
In several species of nonhuman primates screams given by victims of attack elicit interventions from allies in the social group. In the present study, the screams of 16 pigtail macaques (M.
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.
The representation of social relations by monkeys
In captivity, longtailed macaques trained to recognize the relation between one adult female and her offspring can identify the same relation among other mother-offspring pairs, and distinguish this relation from bonds between individuals who are related in a different way.
Aspects of fight interference in free‐ranging and compound‐dwelling rhesus macaques (Macaca mulatta)
While female rhesus monkeys interfered in fights in a manner consistent with the control of aggression and protection of kin, the motives of male interferers remain unknown; however, their behavior is consistent withThe hypothesis that they were reducing intermale tensions while, at the same time, minimizing physical risk.
How vervet monkeys perceive their grunts: Field playback experiments
Abstract Free-ranging vervet monkeys grunt to each other in a variety of social situations: when approaching a dominant or subordinate individual, when moving into a new area of their range, or when
Representational Signaling in Non-Human Primate Vocal Communication
Knowledge about non-human primate vocal communication has grown substantially in recent years and has resulted in a radically different view of the role vocalizations play in animals’ lives. Some 25
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.
