Spontaneous social tool use in chimpanzees (Pan troglodytes)
(2018-11-12) - Journal article,
Although there is good evidence that social animals show elaborate cognitive skills to deal with others, there are few reports of animals physically using social agents and their respective responses as means to an end—social ...
Chimpanzees’ understanding of social leverage
(2018-12-12) - Journal article,
Social primates can influence others through the control of resources. For instance, dominant male chimpanzees might allow subordinates access to mate with females in exchange for social support. However, little is known ...
Differences in the ability of apes and children to instruct others using gestures
(2015) - Journal article,
In all human cultures, people gesture iconically. However, the evolutionary basis of iconic gestures is unknown. In this study, chimpanzees and bonobos, and 2- and 3-year-old children, learned how to operate two apparatuses ...
Younger apes and human children plan their moves in a maze task
(2014-02) - Journal article,
Planning defined as the predetermination of a sequence of actions towards some goal is crucial for complex problem solving. To shed light on the evolution of executive functions, we investigated the ontogenetic and ...
Exceptional evolutionary divergence of human muscle and brain metabolomes parallels human cognitive and physical uniqueness
(2014-05-27) - Journal article,
Metabolite concentrations reflect the physiological states of tissues and cells. However, the role of metabolic changes in species evolution is currently unknown. Here, we present a study of metabolome evolution conducted ...
Cross-species variation in gaze following and conspecific preference among great apes, human infants and adults
(2014-05) - Journal article,
Although previous studies have shown that many species follow gaze, few have directly compared closely related species, and thus its cross-species variation remains largely unclear. In this study, we compared three great ...
Production and comprehension of gestures between orang-utans (Pongo pygmaeus) in a referential communication game
(2015-06-19) - Journal article,
Orang-utans played a communication game in two studies testing their ability to produce and comprehend requestive pointing. While the 'communicator' could see but not obtain hidden food, the 'donor' could release the food ...
Chimpanzees coordinate in a snowdrift game
(2016-06) - Journal article,
The snowdrift game is a model for studying social coordination in the context of competing interests. We presented pairs of chimpanzees, Pan troglodytes, with a situation in which they could either pull a weighted tray ...
How chimpanzees (Pan troglodytes) perform in a modified emotional Stroop task
(2016-05) - Journal article,
The emotional Stroop task is an experimental paradigm developed to study the relationship between emotion and cognition. Human participants required to identify the color of words typically respond more slowly to negative ...
