Social manipulation in nonhuman primates: cognitive and motivational determinants
(2017-11) - Journal item,
Social interactions are the result of individuals’ cooperative and competitive tendencies expressed over an extended period of time. Although social manipulation, i.e., using another individual to achieve one’s own goals, ...
Chimpanzees Extract Social Information from Agonistic Screams
(2010-07-14) - Journal article,
Chimpanzee (Pan troglodytes) agonistic screams are graded vocal signals that are produced in a context-specific manner. Screams given by aggressors and victims can be discriminated based on their acoustic structure but the ...
The nature of prosociality in chimpanzees
(2016-12-20) - Journal article,
An important debate centres around the nature of prosociality in nonhuman primates. Chimpanzees help other individuals in some experimental settings, yet they do not readily share food. One solution to this paradox is that ...
Distinctiveness enhances long-term event memory in non-human primates, irrespective of reinforcement
(2017-08) - Journal article,
Non-human primates are capable of recalling events that occurred as long as three years ago, and are able to distinguish between similar events; akin to human memory. In humans, distinctiveness enhances memory for events, ...
Eye tracking uncovered great apes' ability to anticipate that other individuals will act according to false beliefs
(2017) - Journal article,
Using a novel eye-tracking test, we recently showed that great apes anticipate that other individuals will act according to false beliefs. This finding suggests that, like humans, great apes understand others' false beliefs, ...
Great apes and children infer causal relations from patterns of variation and covariation
(2016-10) - Journal article,
We investigated whether nonhuman great apes (N=23), 2.5-year-old (N=20), and 3-year-old children (N=40) infer causal relations from patterns of variation and covariation by adapting the blicket detector paradigm for apes. ...
The role of past interactions in great apes’ communication about absent entities
(2016-11) - Journal article,
Recent evidence suggests that great apes can use the former location of an entity to communicate about it. In this study we built on these findings to investigate the social cognitive foundations of great apes’ communicative ...
Untrained chimpanzees (Pan troglodytes schweinfurthii) fail to imitate novel actions
(2012-08-08) - Journal article,
Background: Social learning research in apes has focused on social learning in the technical (problem solving) domain - an approach that confounds action and physical information. Successful subjects in such studies may ...
Sequential Tool Use in Great Apes
(2012-12-26) - Journal article,
Sequential tool use is defined as using a tool to obtain another non-food object which subsequently itself will serve as a tool to act upon a further ( sub) goal. Previous studies have shown that birds and great apes succeed ...
