Document Summary
Lecture 14: social competence iii: understanding perception (continued) Why don"t chimps pass object choice tasks? dogs perform better than chimps. 1999: another chimp approaches location, food bark. In order to get food, would have to take into account what other chimps were seeing/thinking. Doors closed so dominant and subordinate could not see hiding: 2. Doors opened to allow chimps to see and enter rooms: 3. Results: subordinates obtained more food in the condition in which the dominant did not see half the food, subordinates went to the food that was unseen to the dominant. Flombaum & santos (2005): rhesus macaques: understanding intentions. Experimenter unwilling (just sitting there holding food) Experimenter unable (trying to give good but failing ie. the food would fall down) Only difference is the intention of the actor. Chimps were more agitated in unwilling condition: understanding knowing. Subordinant/dominant chimp task tells us they know what the other can see, but not necessarily what the other knows.
