Lecture 5: Learning
Learning as Contiguity
- Associations
How we put things together in our mind.
o(i.e.: Chevy + girl example)
1. Pretty girl arousal
2. Chevy no arousal
3. Pretty girl + Chevy = arousal
4. Chevy arousal
John Locke; all learning is a consequence of this building associations.
oTabula rasa: children are born as blank slates, and experiences
are written onto them. Through these associations, the child
learns about the things in their world.
oi.e.: Mommy + milk association
Ivan Pavlov; a biologist, not a psychologist, but best known for his
psychology research. Received a Nobel Prize for his works with the
digestive system.
oConducted experiments looking into a dog’s digestive system
through a window he surgically installed.
o“Psychic secretions” occurred as Pavlov called them, when the
dogs were starved and then shown food.
oClassical (Pavlovian) Conditioning: “Pavlov’s Dog”
1. food salivation
2. bell no salivation
3. bell + food = salivation
4. bell salivation

Classical conditioning does not require conscious effort. It occurs
naturally.
Learning is a relatively permanent acquisition of new behaviour as a
result of experience. Anything that can be learned can be unlearned
as well.
oAcquisition: beginning to make the association between objects.
oExtinction: if the neutral and unconditioned stimuli aren’t paired
together for a protracted period of time, the new stimulus
response weakens.
