  Title Male monkeys remember which group members have given alarm calls Type Journal Article
  Year 2006 Publication Proceedings. Biological Sciences / The Royal Society Abbreviated Journal Proc Biol Sci  
  Volume 273 Issue 1587 Pages 735-740  
  Keywords Animals; Behavior, Animal/*physiology; Cercopithecidae/*physiology/*psychology; Cognition/physiology; Fear/physiology/*psychology; Female; Indonesia; Male; Vocalization, Animal/*physiology  
  Abstract Primates give alarm calls in response to the presence of predators. In some species, such as the Thomas langur (Presbytis thomasi), males only emit alarm calls if there is an audience. An unanswered question is whether the audience's behaviour influences how long the male will continue his alarm calling. We tested three hypotheses that might explain the alarm calling duration of male Thomas langurs: the fatigue, group size and group member behaviour hypotheses. Fatigue and group size did not influence male alarm calling duration. We found that males only ceased calling shortly after all individuals in his group had given at least one alarm call. This shows that males keep track of and thus remember which group members have called.

  Title How do apes ape? Type Journal Article
  Year 2004 Publication Learning & Behavior Abbreviated Journal Learn. Behav.  
  Volume 32 Issue 1 Pages 36-52  
  Keywords Adaptation, Psychological; Animals; Behavior, Animal; Hominidae/*psychology; *Imitative Behavior; Imprinting (Psychology); *Learning; Psychological Theory; *Social Environment; *Social Facilitation  
  Abstract In the wake of telling critiques of the foundations on which earlier conclusions were based, the last 15 years have witnessed a renaissance in the study of social learning in apes. As a result, we are able to review 31 experimental studies from this period in which social learning in chimpanzees, gorillas, and orangutans has been investigated. The principal question framed at the beginning of this era, Do apes ape? has been answered in the affirmative, at least in certain conditions. The more interesting question now is, thus, How do apes ape? Answering this question has engendered richer taxonomies of the range of social-learning processes at work and new methodologies to uncover them. Together, these studies suggest that apes ape by employing a portfolio of alternative social-learning processes in flexibly adaptive ways, in conjunction with nonsocial learning. We conclude by sketching the kind of decision tree that appears to underlie the deployment of these alternatives.

  Title Conformity to cultural norms of tool use in chimpanzees Type Journal Article
  Year 2005 Publication Nature Abbreviated Journal Nature  
  Volume 437 Issue 7059 Pages 737-740  
  Keywords Aging/physiology; Animals; Culture; Feeding Behavior/physiology; Female; Pan troglodytes/*physiology/*psychology; *Social Conformity; Technology; Time Factors  
  Abstract Rich circumstantial evidence suggests that the extensive behavioural diversity recorded in wild great apes reflects a complexity of cultural variation unmatched by species other than our own. However, the capacity for cultural transmission assumed by this interpretation has remained difficult to test rigorously in the field, where the scope for controlled experimentation is limited. Here we show that experimentally introduced technologies will spread within different ape communities. Unobserved by group mates, we first trained a high-ranking female from each of two groups of captive chimpanzees to adopt one of two different tool-use techniques for obtaining food from the same 'Pan-pipe' apparatus, then re-introduced each female to her respective group. All but two of 32 chimpanzees mastered the new technique under the influence of their local expert, whereas none did so in a third population lacking an expert. Most chimpanzees adopted the method seeded in their group, and these traditions continued to diverge over time. A subset of chimpanzees that discovered the alternative method nevertheless went on to match the predominant approach of their companions, showing a conformity bias that is regarded as a hallmark of human culture.

  Title Cultures in chimpanzees Type Journal Article
  Year 1999 Publication Nature Abbreviated Journal Nature  
  Volume 399 Issue 6737 Pages 682-685  
  Keywords Animals; *Behavior, Animal; Cognition; *Culture; Humans; Pan troglodytes/*physiology; Species Specificity  
  Abstract As an increasing number of field studies of chimpanzees (Pan troglodytes) have achieved long-term status across Africa, differences in the behavioural repertoires described have become apparent that suggest there is significant cultural variation. Here we present a systematic synthesis of this information from the seven most long-term studies, which together have accumulated 151 years of chimpanzee observation. This comprehensive analysis reveals patterns of variation that are far more extensive than have previously been documented for any animal species except humans. We find that 39 different behaviour patterns, including tool usage, grooming and courtship behaviours, are customary or habitual in some communities but are absent in others where ecological explanations have been discounted. Among mammalian and avian species, cultural variation has previously been identified only for single behaviour patterns, such as the local dialects of song-birds. The extensive, multiple variations now documented for chimpanzees are thus without parallel. Moreover, the combined repertoire of these behaviour patterns in each chimpanzee community is itself highly distinctive, a phenomenon characteristic of human cultures but previously unrecognised in non-human species.

  Title Imitative learning of artificial fruit processing in children (Homo sapiens) and chimpanzees (Pan troglodytes) Type Journal Article
  Year 1996 Publication Journal of comparative psychology (Washington, D.C. : 1983) Abbreviated Journal J Comp Psychol  
  Volume 110 Issue 1 Pages 3-14  
  Keywords Animals; Child, Preschool; Discrimination Learning; Female; Food Preferences/*psychology; *Fruit; Humans; *Imitative Behavior; Male; Mental Recall; Pan troglodytes/*psychology; Social Environment  
  Abstract Observational learning in chimpanzees and young children was investigated using an artificial fruit designed as an analog of natural foraging problems faced by primates. Each of 3 principal components could be removed in 2 alternative ways, demonstration of only one of which was watched by each subject. This permitted subsequent imitation by subjects to be distinguished from stimulus enhancement. Children aged 2-4 years evidenced imitation for 2 components, but also achieved demonstrated outcomes through their own techniques. Chimpanzees relied even more on their own techniques, but they did imitate elements of 1 component of the task. To our knowledge, this is the first experimental evidence of chimpanzee imitation in a functional task designed to simulate foraging behavior hypothesized to be transmitted culturally in the wild.

  Keywords Animals; Animals, Wild/physiology/psychology; Behavior, Animal/*physiology; *Culture; Female; Humans; Imitative Behavior; Learning/*physiology; Pan troglodytes/*physiology/psychology; *Social Behavior; Technology  
  Abstract Half a century of dedicated field research has brought us from ignorance of our closest relatives to the discovery that chimpanzee communities resemble human cultures in possessing suites of local traditions that uniquely identify them. The collaborative effort required to establish this picture parallels the one set up to sequence the chimpanzee genome, and has revealed a complex social inheritance system that complements the genetic picture we are now developing.

  Title Imitation of the sequential structure of actions by chimpanzees (Pan troglodytes) Type Journal Article
  Year 1998 Publication Journal of comparative psychology (Washington, D.C. : 1983) Abbreviated Journal J Comp Psychol  
  Volume 112 Issue 3 Pages 270-281  
  Keywords Animals; Appetitive Behavior/physiology; *Ceremonial Behavior; Exploratory Behavior/physiology; Female; Fruit; Imitative Behavior/*physiology; Learning/*physiology; Male; Pan troglodytes/*psychology; Practice (Psychology); Problem Solving/*physiology  
  Abstract Imitation was studied experimentally by allowing chimpanzees (Pan troglodytes) to observe alternative patterns of actions for opening a specially designed “artificial fruit.” Like problematic foods primates deal with naturally, with the test fruit several defenses had to be removed to gain access to an edible core, but the sequential order and method of defense removal could be systematically varied. Each subject repeatedly observed 1 of 2 alternative techniques for removing each defense and 1 of 2 alternative sequential patterns of defense removal. Imitation of sequential organization emerged after repeated cycles of demonstration and attempts at opening the fruit. Imitation in chimpanzees may thus have some power to produce cultural convergence, counter to the supposition that individual learning processes corrupt copied actions. Imitation of sequential organization was accompanied by imitation of some aspects of the techniques that made up the sequence.
