LEARNING

Behaviorism Classical conditioning

Type of associative learning Organisms associate events

PAVLOV’S FINDINGS

PAVLOV’S FINDINGS

CLASSICAL CONDITIONING BASICS

Unconditioned Stimulus (UCS) Naturally Triggers Response

Unconditioned Response (UCR) Naturally Occurring Response

Conditioned Stimulus (CS) Irrelevant Stimulus; Repeated paired with UCS

Conditioned Response (CR) Learned Response

PAVLOV’S FINDINGS

BUT JUST FOR DOGS, RIGHT?

CS alone No response

BUT JUST FOR DOGS, RIGHT?

CS alone No response

UCS UCR

LET’S COMPARE PAVLOV AND JIM…

Pavlov The Office

UCS Meat Powder Breath Mint

CS Tone Computer Beep

UCR Salivation Salivation (+ minty fresh)

CR Salivation Salivation (-minty fresh)

BREAKING IT DOWN

Computer beep no response Eating breath mint salivation (fresh breath) Eating breath mint + beep salivation Eating breath mint + beep salivation Eating breath mint + beep salivation ……..

Computer beep salivation

ONE LAST CC EXAMPLE

CLICKER QUESTION As a child, you were playing in the yard one

day when a neighbor’s cat wandered over. Your mother screamed and brought you inside. Her behavior caused you to cry. You now have a fear of cats. The unconditioned stimulus (UCS) is

A. Your mother’s behavior.B. Your crying.C. The cat.D. Your fear of cats today.

ACQUISITION AND EXTINCTION

Acquisition Initial learning and timing

Extinction Only CS is presented

Spontaneous Recovery

IMPORTANCE OF CC

Learning enables animals to become responsive to adapt to their environments

Other Examples Taste aversion Emotions Immune System

LIMITS OF CC

Apply to physiological responses Mechanical explanation
