	Title	Reciprocal recognition of sifaka ( Propithecus verreauxi verreauxi) and redfronted lemur ( Eulemur fulvus rufus) alarm calls			Type	Journal Article
	Year	2004	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	7	Issue	1	Pages	45-52
	Keywords	Animals; Arousal; Escape Reaction; Female; Lemuridae/physiology/psychology; Male; Papio; Recognition (Psychology); Strepsirhini/physiology/psychology; Tape Recording; *Vocalization, Animal
	Abstract	Redfronted lemurs ( Eulemur fulvus rufus) and Verreaux's sifakas ( Propithecus verreauxi verreauxi) occur sympatrically in western Madagascar. Both species exhibit a so-called mixed alarm call system with functionally referential alarm calls for raptors and general alarm calls for carnivores and raptors. General alarm calls also occur in other contexts associated with high arousal, such as inter-group encounters. Field playback experiments were conducted to investigate whether interspecific recognition of alarm calls occurs in both species, even though the two species rarely interact. In a crossed design, redfronted lemur and sifaka alarm calls were broadcast to individuals of both species, using the alarm call of chacma baboons ( Papio cynocephalus) as a control. Both species responded with appropriate escape strategies and alarm calls after playbacks of heterospecific aerial alarm calls. Similarly, they reacted appropriately to playbacks of heterospecific general alarm calls. Playbacks of baboon alarm calls elicited no specific responses in either lemur species, indicating that an understanding of interspecific alarm calls caused the responses and not alarm calls in general. Thus, the two lemur species have an understanding of each other's aerial as well as general alarm calls, suggesting that even in species that do not form mutualistic associations and rarely interact, common predator pressure has been sufficient for the development of heterospecific call recognition.

	Title	Vocalizations of rhesus (Macaca mulatta) and Japanese (M. fuscata) macaques cross-fostered between species show evidence of only limited modification			Type	Journal Article
	Year	1993	Publication	Developmental psychobiology	Abbreviated Journal	Dev Psychobiol
	Volume	26	Issue	7	Pages	389-406
	Keywords	Animals; Animals, Newborn; Behavior, Animal; Discrimination Learning; Environment; Female; Macaca; Macaca mulatta; Male; Sound Spectrography; *Vocalization, Animal
	Abstract	Two rhesus and two Japanese macaque infants were cross-fostered between species in order to study the effects of auditory experience on vocal development. Both the cross-fostered and normally raised control subjects were observed over the first 2 years of life and their vocalizations were tape-recorded. We classified 8053 calls by ear, placed each call in one of six acoustic categories, and calculated the rates at which different call-types were used in different social contexts. Species differences were found in the use of “coo” and “gruff” vocalizations among control subjects. Japanese macaques invariably produced coos almost exclusively. In contrast, rhesus macaques produced a mixture of coos and gruffs and showed considerable interindividual variation in the relative use of one call type or the other. Cross-fostered Japanese macaques adhered to their species-typical behavior, rarely using gruffs. Cross-fostered rhesus subjects also exhibited species-typical behavior in many contexts, but in some situations produced coos and gruffs at rates that were intermediate between those shown by normally raised animals of the two species. This outcome suggests that environmentally mediated modification of vocal behavior may have occurred, but that the resulting changes were quite limited.

	Title	Within-species variation in the development of ultrasonic signaling of preweanling rats			Type	Journal Article
	Year	1979	Publication	Developmental Psychobiology	Abbreviated Journal	Dev Psychobiol
	Volume	12	Issue	2	Pages	129-136
	Keywords	Animals; Animals, Newborn; Animals, Suckling; Body Weight; Cold/adverse effects; Environment; Genotype; Individuality; Object Attachment; Rats; Stress/physiopathology; Ultrasonics; *Vocalization, Animal
	Abstract	The development of litter and individual differences in the rate of ultrasonic signaling of neonatal rats was studied. Systematic variations among litters and individuals emerged, without differential treatment. These differences were not correlated with variations in general development as indexed by body weight. Two experiments using a cross-fostering design showed that litter differences developed independently of variations in postnatal environment. These results indicate that the variations among litters in ultrasound rate have a prenatal, possibly genetic, etiology and may represent reliable indicants of response to environmental stress.

	Title	Behavioral measurement of temperament in male nursery-raised infant macaques and baboons			Type	Journal Article
	Year	1999	Publication	American journal of primatology	Abbreviated Journal	Am. J. Primatol.

	Abstract	We define temperament as an individual's set of characteristic behavioral responses to novel or challenging stimuli. This study adapted a temperament scale used with rhesus macaques by Schneider and colleagues [American Journal of Primatology 25:137-155, 1991] for use with male pigtailed macaque (Macaca nemestrina, n = 7), longtailed macaque (M. fascicularis, n = 3), and baboon infants (Papio cynocephalus anubis, n = 4). Subjects were evaluated twice weekly for the first 5 months of age during routine removal from their cages for weighing. Behavioral measures were based on the subject's interactions with a familiar human caretaker and included predominant state before capture, response to capture, contact latency, resistance to tester's hold, degree of clinging, attention to environment, defecation/urination, consolability, facial expression, vocalizations, and irritability. Species differences indicated that baboons were more active than macaques in establishing or terminating contact with the tester. Temperament scores decreased over time for the variables Response to Capture and Contact Latency, indicating that as they grew older, subjects became less reactive and more bold in their interactions with the tester. Temperament scores changed slowly with age, with greater change occurring at younger ages. The retention of variability in reactivity between and within species may be advantageous for primates, reflecting the flexibility necessary to survive in a changing environment.

	Title	Modification of reconciliation behavior through social experience: an experiment with two macaque species			Type	Journal Article
	Year	1993	Publication	Child development	Abbreviated Journal	Child Dev
	Volume	64	Issue	3	Pages	897-908
	Keywords	Aggression; Animals; Behavior, Animal; Female; Grooming; Macaca; Macaca mulatta; Male; Play and Playthings; Socialization; Vocalization, Animal
	Abstract	Reconciliation, defined as a friendly reunion between former opponents shortly after an aggressive encounter, is common in the stumptail macaque (Macaca arctoides) but rare in the rhesus macaque (M. mulatta). Juveniles of the two species were cohoused for 5 months, after which they were observed with conspecifics only. Control rhesus monkeys, matched in age and sex to the experimental subjects, went through the same procedure without exposure to the other species. A threefold increase in the proportion of reconciled fights was measured in the rhesus subjects. The difference emerged gradually during cohousing with the tutor species and was sustained following removal of this species. Other behavior, such as grooming and aggression, decreased over time. It is suggested that the social attitude of the subjects was affected through contact with a species characterized by a more relaxed dominance style.

	Title	Action imitation in birds			Type	Journal Article
	Year	2004	Publication	Learning & behavior : a Psychonomic Society publication	Abbreviated Journal	Learn Behav
	Volume	32	Issue	1	Pages	15-23
	Keywords	Adaptation, Psychological; Animals; Birds; Imitative Behavior; Imprinting (Psychology); Learning; Motivation; Psychological Theory; Social Environment; *Social Facilitation; Vocalization, Animal
	Abstract	Action imitation, once thought to be a behavior almost exclusively limited to humans and the great apes, surprisingly also has been found in a number of bird species. Because imitation has been viewed by some psychologists as a form of intelligent behavior, there has been interest in how it is distributed among animal species. Although the mechanisms responsible for action imitation are not clear, we are now at least beginning to understand the conditions under which it occurs. In this article, I try to identify and differentiate the various forms of socially influenced behavior (species-typical social reactions, social effects on motivation, social effects on perception, socially influenced learning, and action imitation) and explain why it is important to differentiate imitation from other forms of social influence. I also examine some of the variables that appear to be involved in the occurrence of imitation. Finally, I speculate about why a number of bird species, but few mammal species, appear to imitate.

	Title	The responses of female baboons (Papio cynocephalus ursinus) to anomalous social interactions: evidence for causal reasoning?			Type	Journal Article
	Year	1995	Publication	Journal of comparative psychology (Washington, D.C. : 1983)	Abbreviated Journal	J Comp Psychol
	Volume	109	Issue	2	Pages	134-141
	Keywords	Animals; Attention; Auditory Perception; Awareness; Concept Formation; Dominance-Subordination; Fear; Female; Hierarchy, Social; Papio/psychology; *Social Behavior; Social Environment; Vocalization, Animal
	Abstract	Baboons' (Papio cynocephalus ursinus) understanding of cause-effect relations in the context of social interactions was examined through use of a playback experiment. Under natural conditions, dominant female baboons often grunt to more subordinate mothers when interacting with their infants. Mothers occasionally respond to these grunts by uttering submissive fear barks. Subjects were played causally inconsistent call sequences in which a lower ranking female apparently grunted to a higher ranking female, and the higher ranking female apparently responded with fear barks. As a control, subjects heard a sequence made causally consistent by the inclusion of grunts from a 3rd female that was dominant to both of the others. Subjects responded significantly more strongly to the causally inconsistent sequences, suggesting that they recognized the factors that cause 1 individual to give submissive vocalizations to another.

	Title	Monkey responses to three different alarm calls: evidence of predator classification and semantic communication			Type	Journal Article
	Year	1980	Publication	Science (New York, N.Y.)	Abbreviated Journal	Science
	Volume	210	Issue	4471	Pages	801-803
	Keywords	Animal Communication; Animals; Behavior, Animal/physiology; Cercopithecidae/physiology; Fear; Female; Male; Predatory Behavior; Vocalization, Animal
	Abstract	Vervet monkeys give different alarm calls to different predators. Recordings of the alarms played back when predators were absent caused the monkeys to run into trees for leopard alarms, look up for eagle alarms, and look down for snake alarms. Adults call primarily to leopards, martial eagles, and pythons, but infants give leopard alarms to various mammals, eagle alarms to many birds, and snake alarms to various snakelike objects. Predator classification improves with age and experience.

	Title	Meaning and emotion in animal vocalizations			Type	Journal Article
	Year	2003	Publication	Annals of the New York Academy of Sciences	Abbreviated Journal	Ann N Y Acad Sci
	Volume	1000	Issue		Pages	32-55
	Keywords	Acoustics; Affect; Animals; Behavior, Animal; Intention; Posture; Sound Spectrography; *Vocalization, Animal
	Abstract	Historically, a dichotomy has been drawn between the semantic communication of human language and the apparently emotional calls of animals. Current research paints a more complicated picture. Just as scientists have identified elements of human speech that reflect a speaker's emotions, field experiments have shown that the calls of many animals provide listeners with information about objects and events in the environment. Like human speech, therefore, animal vocalizations simultaneously provide others with information that is both semantic and emotional. In support of this conclusion, we review the results of field experiments on the natural vocalizations of African vervet monkeys, diana monkeys, baboons, and suricates (a South African mongoose). Vervet and diana monkeys give acoustically distinct alarm calls in response to the presence of leopards, eagles, and snakes. Each alarm call type elicits a different, adaptive response from others nearby. Field experiments demonstrate that listeners compare these vocalizations not just according to their acoustic properties but also according to the information they convey. Like monkeys, suricates give acoustically distinct alarm calls in response to different predators. Within each predator class, the calls also differ acoustically according to the signaler's perception of urgency. Like speech, therefore, suricate alarm calls convey both semantic and emotional information. The vocalizations of baboons, like those of many birds and mammals, are individually distinctive. As a result, when one baboon hears a sequence of calls exchanged between two or more individuals, the listener acquires information about social events in its group. Baboons, moreover, are skilled “eavesdroppers:” their response to different call sequences provides evidence of the sophisticated information they acquire from other individuals' vocalizations. Baboon males give loud “wahoo” calls during competitive displays. Like other vocalizations, these highly emotional calls provide listeners with information about the caller's dominance rank, age, and competitive ability. Although animal vocalizations, like human speech, simultaneously encode both semantic and emotional information, they differ from language in at least one fundamental respect. Although listeners acquire rich information from a caller's vocalization, callers do not, in the human sense, intend to provide it. Listeners acquire information as an inadvertent consequence of signaler behavior.
