Personality in great apes
Great apes exhibit pronounced individual differences in their
behaviours. How do their individual-specific behaviours influence
captive management? A study in collaboration with various zoological
institutions in Europe, the Great Ape Taxon Advisory Group of the
European Endangered Species Programs and the
European Association of Zoos and Aquaria (EAZA)
Personality differences in rhesus macaques
In which ways differ semi-free ranging individuals of Rhesus
macaques from one another? A study in cooperation with
Prof Dr Anja Widdig, Leipzig University and Max Planck Institute
for Evolutionary Anthropology, Leipzig, Germany.
Personality and social relationships in capuchin monkeys
What roles do individual differences play in social
relationships? We explore this fascinating question in capuchin
monkeys, a group-living primate species endemic to South-America. In
cooperation with
Dr
Elisabetta Visalberghi and Dr Elsa Addessi, ISTC-CNR,
Unit of Cognitive Primatology and Primate Centre, Rome, Italy.
Personality and social relationships in Crab-eating macaques
In what ways do individual differences in crab-eating macaques
affect their social relationships? A study in cooperation with
Karlijn
Gosselt-Gielen, Department for Behavioural Biology of the University
Utrecht.
Personality and social relationships in gorillas
Gorillas are known to show pronounced individual-specific
behaviours. How does the individuals' "personality" influence their
social relationships? A study in cooperation with
Apenheul Primate Park, The Netherlands.

Personality differences in capuchin monkeys
What kinds of individual-specific behaviours do capuchin monkeys
(Sapajus spp.) exhibit and how can these 'personality
differences' be empirically quantified and categorised? What
impressions of capuchin individuals do human observers develop and
how do their 'personality' assessments of capuchins relate to these
monkeys' behaviours? To explore these questions, we developed a
series of 15 behavioural tests and 2 group observations to study the
capuchins of the Primate Centre in Rome. In addition, we conducted a
large survey using the two formats of the
Capuchin Personality Inventory (CPI-TA and -BV) and involving
150 capuchin monkeys at nine research institutions worldwide. In
cooperation with
Dr
Elisabetta Visalberghi and Dr Elsa Addessi,
ISTC-CNR Unit of Cognitive Primatology and Primate Centre,
Rome.

Between-individual and between-species differences in primate
behaviour
Nonhuman primates often exhibit striking individual differences,
such as in aggressive or social behaviours. In these behaviours,
there are also pronounced differences between species. Building on
methods from cross-cultural psychology, this research developed a
comprehensive research methodology for exploring and quantifying
individual and species differences in behaviour. Empirical
applications are demonstrated in four monkey species, Weeper
capuchin monkeys (Cebus olivaceus), mandrills (Mandrillus
sphinx), toque macaques (Macaca sinica) and Rhesus
macaques (Macaca mulatta). A study in cooperation with the
Zoo Berlin and the
Berlin Animal Shelter (Tierschutzverein für Berlin und Umgebung
Corporation e.V). and the
German Animal Welfare Federation (Deutscher Tierschutzbund
e.V.).

Personality differences in Crab-eating macaques
What kinds of individual-specific behaviours do crab-eating macaques
(Macaca fascicularis) show and how can these be categorised?
What impressions do human observers develop of the macaque
individuals' 'personality' and how do their assessments relate to
the monkeys' behaviours? Together with
Karlijn
Gosselt-Gielen, Department for Behavioural Biology, University
Utrecht, we explored these questions in a 3-year and 6-wave
study involving 104 macaques and 99 human observers. We used a
complex multi-method design involving behavioural observations and
the two formats of the
Macaque Personality Inventory for captive individuals (MPIc-TA
and BV).

Personality in the Great Apes - Methods and approaches
How can we measure 'personality differences' reliably in
nonhuman species? Can methods and theories from human 'personality'
research be adapted for this purpose? This project addressed these
questions in multi-method studies conducted with Great Apes at the
Max-Planck Institute for Evolutionary Anthropology and
Wolfgang Köhler Primate Research Center
at Leipzig Zoo.
They involved a series of 14 behavioural tests and 2 group
observations as well as the two formats of the
Great Ape Personality Inventory (GAPI-A and -B). Twenty great
apes were studied, chimpanzees (Pan troglodytes), bonobos (Pan
paniscus), gorillas (Gorilla gorilla), orangutans (Pongo
abelii; Pongo pygmaeus).
