Coordination of joint activities and communication in wild chimpanzees (Pan troglodytes) of the Budongo Forest, Uganda
(University of St Andrews, 2015) - Thesis
Evidence from captive studies suggests that chimpanzees (Pan troglodytes) lack the
motivation to complete cooperative tasks and there is little evidence for communication
that coordinates their behaviour during joint ...
Intra-sexual competition and vocal counter-strategies in wild female chimpanzees (Pan troglodytes schweinfurthii)
(University of St Andrews, 2009) - Thesis
A growing body of behavioural data is beginning to show that, like their male counterparts,
female chimpanzees can be competitive and aggressive, particularly when resources come
under pressure. These observations are ...
Vocal communication in bonobos (Pan paniscus) : studies in the contexts of feeding and sex
(University of St Andrews, 2011-06) - Thesis
Despite having being discovered nearly 80 years ago, bonobos (Pan paniscus) are still one of the least well understood of the great apes, largely remaining in the shadow of their better known cousins, the chimpanzees (Pan ...
Anti-predator behaviour of black-fronted titi monkeys (Callicebus nigrifrons)
(University of St Andrews, 2012-06) - Thesis
Titi monkeys have long been known for their complex vocal behaviour with numerous high- and low-pitched calls, which can be uttered singly or combined in more complex structures. However, up to date very little is known ...
The vocalisations and anti-predatory behaviour of wild white-handed gibbons (Hylobates lar) in Khao Yai National Park, Thailand
(University of St Andrews, 2010) - Thesis
The loud songs of gibbons (Hylobatidae) usually consist of a duet by the mated pair
delivered each morning. These songs can transmit over a kilometre through dense
forest habitat and therefore presumably play a role in ...
Anti-predator behaviour of Guereza colobus monkeys (Colobus guereza)
(University of St Andrews, 2009-06-24) - Thesis
Black-and-white colobus monkeys are renowned for their impressive vocal behaviour, but up to date there have been only very few systematic efforts to study this. These monkeys are able to produce loud and low-pitched roars ...
Social life and flexibility of vocal behaviour in Diana monkeys and other cercopithecids
(University of St Andrews, 2013) - Thesis
Recent studies on the social life and vocal production, usage and comprehension of nonhuman primates have brought new insights into the evolutionary mechanisms of cognition and communication as well as the emergence of ...
Form and function of non-linguistic calls in human infants
(University of St Andrews, 2012-06-19) - Thesis
Before infants speak their first word, they already produce a large variety of sounds. Whilst the developmental process that leads to speech production is very well documented, little attention is given to how non-linguistic ...
A cognitive approach to the study of culture in wild chimpanzees (Pan troglodytes schweinfurthii)
(University of St Andrews, 2011-11-30) - Thesis
The question of animal culture has been of interest for decades. Chimpanzees (Pan
troglodytes) have played a key role in the debate of whether or not it is appropriate to use the
term ‘culture’ to describe animal behaviour ...
Attention following and nonverbal referential communication in bonobos (Pan paniscus), chimpanzees (Pan troglodytes) and orangutans (Pongo pygmaeus)
(University of St Andrews, 2011-06-22) - Thesis
A central issue in the study of primate communication is the extent to which individuals adjust their behaviour to the attention and signals of others, and manipulate others’ attention to communicate about external events. ...
