About the Section of Language and Intelligence
Our comparative cognitive studies aim to understand the higher cognitive functions in the great apes, especially in the chimpanzee, the closest relative of humans. Both experimental and observational approaches illuminate the similarities and the differences between human cognition and ape cognition.
The research topics of this laboratory include:
Acquisition and use of a visual articficial language;
Categorization and concept formation;
Establishment of equivalence relations;
Recognition of facial expressions;
Visual search and attention;
Intermodal auditory-visual matching;
Acquisition and use of tokens;
Perception of unity of objects;
Social cognition and communication;
Field experiments in Africa also examine the cognitive processes involved in tool use and cultural transmission in wild populations.
