Social facilitation
○
Capuchin presented with novel food, but when a group was present but not eating the
Capuchin did not become more likely to eat the novel food so social facilitation was
not at work
Capuchin more likely to eat the novel food when others of his kind were shown eating
familiar food so Local Enhancement was at work
Capuchin foraging forage on palm nuts-experiment of use of both social facilitation and local
enhancement

Conditioning effects
Emulating learning
Chimps were using tools as well
□
Younger chimps observe what older ones do
Nurture has a lot of effect on an individual- what they see is what they
learn
Acquisition of a topographically novel response through observation of a
demonstrator making that response
There must be some new behavior learned from the observer, and that
behavior must involve some sort of new topographic manipulation as well
as lead to the achievement of some goal
An observer bird watches the model trained bird get food and can imitate
to learn how to get food
The brain senses the mismatch of the sensation and relieves
pain
Some patients have responded very well to mirror therapy-patient
observes a mirror with the illusion that the amputated limb is
moving
◊
Variant involves illusory touch that has helped some who didn't
respond to the first
◊
Phantom limb pain often occurs immediately after surgery, but can occur
later, and in most causes pain lasts for many years
Imitation

Document Summary
Drawn there because there is someone else there eating already. Following others to learn where a good location to eat would be. Presence of one or more of its species in the same place draws in an observer. Safety in numbers-just the presence of their kind specific. Capuchin foraging forage on palm nuts-experiment of use of both social facilitation and local enhancement. Capuchin presented with novel food, but when a group was present but not eating the. Capuchin did not become more likely to eat the novel food so social facilitation was not at work. Capuchin more likely to eat the novel food when others of his kind were shown eating familiar food so local enhancement was at work. Nurture has a lot of effect on an individual- what they see is what they learn. Acquisition of a topographically novel response through observation of a demonstrator making that response.
