Thoughts on Learning

"Learning is not compulsory. Neither is survival."

What is Learning?

A relatively permanent change in behavior

that results from experience

Types of Learning

* Classical conditioning

* Operant conditioning

* Cognitive and social learning

Classical Conditioning: Examples

* Sound of a dentist's drill: sweaty palms

* Smell of mom's perfume: smiling

* Sight of certain restaurant: nausea

* Noise of a can opener: cat comes running

* Smell of a hospital: weakened immunity

Classical Conditioning

* Discovered (accidentally) by Ivan Pavlov

Pavlov's Observation

* Studied digestion in dogs

Pavlov's Experiment: Phase 1

* Food (US): salivation (UR)

- Reflexive response

* Tone (CS): nothing (CR)

Pavlov's Experiment: Phase 2

* CS is repeatedly paired with the US

- A tone is sounded before the food is presented

Pavlov's Experiment: Phase 3

* Eventually, the CS elicits a new CR

- Hearing the tone by itself causes salivation

Classical Conditioning:

Conditioned Emotional Response

* Avoidance learning

* Conditioned phobias

- Little Albert

Classical Conditioning

* Extinction
