	Title	Socially biased learning in monkeys			Type	Journal Article
	Year	2004	Publication	Learning & behavior : a Psychonomic Society publication	Abbreviated Journal	Learn Behav
	Volume	32	Issue	1	Pages	24-35
	Keywords	Adaptation, Psychological; Animal Communication; Animals; Behavior, Animal; Feeding Behavior/psychology; Food Preferences/psychology; Haplorhini/psychology; Imitative Behavior; Imprinting (Psychology); Learning; Social Environment; Social Facilitation
	Abstract	We review socially biased learning about food and problem solving in monkeys, relying especially on studies with tufted capuchin monkeys (Cebus apella) and callitrichid monkeys. Capuchin monkeys most effectively learn to solve a new problem when they can act jointly with an experienced partner in a socially tolerant setting and when the problem can be solved by direct action on an object or substrate, but they do not learn by imitation. Capuchin monkeys are motivated to eat foods, whether familiar or novel, when they are with others that are eating, regardless of what the others are eating. Thus, social bias in learning about foods is indirect and mediated by facilitation of feeding. In most respects, social biases in learning are similar in capuchins and callitrichids, except that callitrichids provide more specific behavioral cues to others about the availability and palatability of foods. Callitrichids generally are more tolerant toward group members and coordinate their activity in space and time more closely than capuchins do. These characteristics support stronger social biases in learning in callitrichids than in capuchins in some situations. On the other hand, callitrichids' more limited range of manipulative behaviors, greater neophobia, and greater sensitivity to the risk of predation restricts what these monkeys learn in comparison with capuchins. We suggest that socially biased learning is always the collective outcome of interacting physical, social, and individual factors, and that differences across populations and species in social bias in learning reflect variations in all these dimensions. Progress in understanding socially biased learning in nonhuman species will be aided by the development of appropriately detailed models of the richly interconnected processes affecting learning.

	Title	Signalers and receivers in animal communication			Type	Journal Article
	Year	2003	Publication	Annual review of psychology	Abbreviated Journal	Annu Rev Psychol
	Volume	54	Issue		Pages	145-173
	Keywords	Affect; Animal Communication; Animals; Arousal; Auditory Perception; Motivation; Social Behavior; Social Environment; Species Specificity; *Vocalization, Animal
	Abstract	In animal communication natural selection favors callers who vocalize to affect the behavior of listeners and listeners who acquire information from vocalizations, using this information to represent their environment. The acquisition of information in the wild is similar to the learning that occurs in laboratory conditioning experiments. It also has some parallels with language. The dichotomous view that animal signals must be either referential or emotional is false, because they can easily be both: The mechanisms that cause a signaler to vocalize do not limit a listener's ability to extract information from the call. The inability of most animals to recognize the mental states of others distinguishes animal communication most clearly from human language. Whereas signalers may vocalize to change a listener's behavior, they do not call to inform others. Listeners acquire information from signalers who do not, in the human sense, intend to provide it.

	Title	Development of infant baboons' responses to graded bark variants			Type	Journal Article
	Year	2000	Publication	Proceedings. Biological sciences / The Royal Society	Abbreviated Journal	Proc Biol Sci
	Volume	267	Issue	1459	Pages	2317-2321
	Keywords	Animal Communication; Animals; Behavior, Animal; Female; Male; Models, Psychological; Papio/growth & development/physiology; *Vocalization, Animal
	Abstract	We studied the development of infant baboons' (Papio cynocephalus ursinus) responses to conspecific 'barks' in a free-ranging population in the Okavango Delta, Botswana. These barks grade from tonal, harmonically rich calls into calls with a more noisy, harsh structure. Typically, tonal variants are given when the signaller is at risk of losing contact with the group or a particular individual ('contact barks'), whereas harsh variants are given in response to predators ('alarm barks'). We conducted focal observations and playback experiments in which we presented variants of barks recorded from resident adult females. By six months of age, infants reliably discriminated between typical alarm and contact barks and they responded more strongly to intermediate alarm calls than to typical contact barks. Infants of six months and older also recognized their mothers by voice. The ability to discriminate between different call variants developed with increasing age. At two and a half months of age, infants failed to respond at all, whereas at four months they responded irrespective of the call type that was presented. At six months, infants showed adult-like responses by responding strongly to alarm barks but ignoring contact barks. We concluded that infants gradually learn to attach the appropriate meaning to alarm and contact barks.

	Title	Social learning by orangutans (Pongo abelii and Pongo pygmaeus) in a simulated food-processing task			Type	Journal Article
	Year	2003	Publication	Journal of comparative psychology (Washington, D.C. : 1983)	Abbreviated Journal	J Comp Psychol
	Volume	117	Issue	3	Pages	272-282
	Keywords	Animal Communication; Animals; Feeding Behavior; Female; Imitative Behavior; Male; Pongo pygmaeus/psychology; Problem Solving; Psychomotor Performance; Social Environment; Species Specificity; *Transfer (Psychology)
	Abstract	Increasing evidence for behavioral differences between populations of primates has created a resurgence of interest in examining mechanisms of information transfer between individuals. The authors examined the social transmission of information in 15 captive orangutans (Pongo abelii and Pongo pygmaeus) using a simulated food-processing task. Experimental subjects were shown 1 of 2 methods for removing a suite of defenses on an “artificial fruit.” Control subjects were given no prior exposure before interacting with the fruit. Observing a model provided a functional advantage in the task, as significantly more experimental than control subjects opened the fruit. Within the experimental groups, the authors found a trend toward differences in the actual behaviors used to remove 1 of the defenses. Results support observations from the wild implying horizontal transfer of information in orangutans and show that a number of social learning processes are likely to be involved in the transfer of knowledge in this species.

	Title	Social communication in siamangs (Symphalangus syndactylus): use of gestures and facial expressions			Type	Journal Article
	Year	2004	Publication	Primates	Abbreviated Journal	Primates
	Volume	45	Issue	1	Pages	41-57
	Keywords	Age Factors; Animal Communication; Animals; Animals, Zoo/physiology; Cognition; Female; Hylobates/physiology; Kinesics; Male; Sex Factors; Social Behavior; Video Recording
	Abstract	The current study represents the first systematic investigation of the social communication of captive siamangs (Symphalangus syndactylus). The focus was on intentional signals, including tactile and visual gestures, as well as facial expressions and actions. Fourteen individuals from different groups were observed and the signals used by individuals were recorded. Thirty-one different signals, consisting of 12 tactile gestures, 8 visual gestures, 7 actions, and 4 facial expressions, were observed, with tactile gestures and facial expressions appearing most frequently. The range of the signal repertoire increased steadily until the age of six, but declined afterwards in adults. The proportions of the different signal categories used within communicative interactions, in particular actions and facial expressions, also varied depending on age. Group differences could be traced back mainly to social factors or housing conditions. Differences in the repertoire of males and females were most obvious in the sexual context. Overall, most signals were used flexibly, with the majority performed in three or more social contexts and almost one-third of signals used in combination with other signals. Siamangs also adjusted their signals appropriately for the recipient, for example, using visual signals most often when the recipient was already attending (audience effects). These observations are discussed in the context of siamang ecology, social structure, and cognition.

	Title	Gaze alternation during “pointing” by squirrel monkeys (Saimiri sciureus)?			Type	Journal Article
	Year	2007	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	10	Issue	2	Pages	267-271
	Keywords	Animal Communication; Animals; Attention; Behavior, Animal/physiology; Cues; Female; Humans; Learning; Male; Saimiri/physiology
	Abstract	Gaze alternation (GA) is considered a hallmark of pointing in human infants, a sign of intentionality underlying the gesture. GA has occasionally been observed in great apes, and reported only anecdotally in a few monkeys. Three squirrel monkeys that had previously learned to reach toward out-of-reach food in the presence of a human partner were videotaped while the latter visually attended to the food, a distractor object, or the ceiling. Frame-by-frame video analysis revealed that, especially when reaching toward the food, the monkeys rapidly and repeatedly switched between looking at the partner's face and the food. This type of GA suggests that the monkeys were communicating with the partner. However, the monkeys' behavior was not influenced by changes in the partner's focus of attention.

	Title	Neonatal imitation in chimpanzees (Pan troglodytes) tested with two paradigms			Type	Journal Article
	Year	2007	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	10	Issue	2	Pages	233-242
	Keywords	Animal Communication; Animals; Animals, Newborn; Imitative Behavior/physiology; Pan troglodytes/physiology/*psychology; Problem Solving/physiology
	Abstract	Primate species differ in their imitative performance, perhaps reflecting differences in imitative capacity. The developmentally earliest form of imitation in humans, neonatal imitation, occurs in early interactions with social partners, and may be a more accurate index of innate capacity than imitation of actions on objects, which requires more cognitive ability. This study assessed imitative capacity in five neonatal chimpanzees, within a narrow age range (7-15 days of age), by testing responses to facial and vocal actions with two different test paradigms (structured and communicative). Imitation of mouth opening was found in both paradigms. In the communicative paradigm, significant agreement was found between infant actions and demonstrations. Additionally, chimpanzees matched the sequence of three actions of the TC model, but only on the second demonstration. Newborn chimpanzees matched more modeled actions in the communicative test than in the structured paradigm. These performances of chimpanzees, at birth, are in agreement with the literature, supporting a conclusion that imitative capacity is not unique to the human species. Developmental histories must be more fully considered in the cross-species study of imitation, as there is a greater degree of innate imitative capacity than previously known. Socialization practices interact with innate and developing competencies to determine the outcome of imitation tests later in life.
