Apes perform like infants in false-belief tasks

Although the extent to which some nonhuman animals understand mental states is currently under debate, attributing false beliefs has been considered to be beyond their limits. A recent study by Krupenye, Kano, Hirata, Call, and Tomasello (Science, 354, 110-114, 2016) shows that great apes pass a false-belief task when they are tested with an anticipatory-looking paradigm developed for nonverbal...

False-belief understanding in infants.

At what age can children attribute false beliefs to others? Traditionally, investigations into this question have used elicited-response tasks in which children are asked a direct question about an agent's false belief. Results from these tasks indicate that the ability to attribute false beliefs does not emerge until about age 4. However, recent investigations using spontaneous-response tasks ...

We consider two different versions of the Smarties task, involving respectively a shift of perspective to another person and to another time. Our formali...

A competitive nonverbal false belief task for children and apes.

A nonverbal false belief task was administered to children (mean age 5 years) and two great ape species: chimpanzees (Pan troglodytes) and bonobos (Pan paniscus).

Two versions were run: in both, a human competitor witnessed an experimenter hide a reward in one of two containers. When the competitor then lef...

Interest contagion in violation-of-expectation-based false-belief tasks

In the debate about how to interpret Violation-of-Expectation (VoE) based false-belief experiments, it has been suggested that infants are predicting the actions of the agent based on more or less sophisticated cognitive means. We present an alternative, more parsimonious interpretation, exploring the possibility that the infants' reactions are not governed by rational expectation but rather of...
