Learning Chapter 3-4

Front 1

Classical Conditioning

Back 1

~simpliest Mechanism
~Organisms learn about relationships bet stimuli
~alter their behaviour accordingly

Front 2

Eairly Years
Pavlov

Back 2

~HIs research in digestive Enzymes
~Saliva at sight of food
~Saliva at sight of person
~"Psychic secrestions" - expectaion of food

Front 3

Classical Conditioning Paradigm
--> Pavlovs two stimuli

Back 3

1. A tone/light thats doesn't elicit salivation at the onset of the experiment

2. Food or the taste of a sour soln placed in the mouth

Front 4

Classical Conditioning Paradigm

Conditioned Stimulis (CS)

Back 4

~not elicit initial response
~Elicits a response upon training
~ex. tone/light

Front 5

Classical Conditioning Paradigm

Unconditioned Stimulus (UCS)

Back 5

~Elicits a response w/out training
~Food/Sour soln
~airpuff

Front 6

Classical Conditioning Paradigm

Conditional response (CR)

Back 6

~response to stimulis as a result of training
ex. sound-->airpuff-->blink
eventually.......
sound-->Blink

Front 7

Classical Conditioning Paradigm

Unconditional Response (UCR)

Back 7

Response to stimulis w/out prior training
(reflex) natural
~ex. Airpuff (UCS)--> blink (UCR)

Front 8

Conditional

Back 8

depend on

Front 9

Fear Conditioning

Back 9

~can be classiclly Conditioned
~ex. Little Albert

Front 10

Little Albert

Back 10

~conditioned a fear response in a 9 month old
~present white lab rat/ banged steel bar

Front 11

Results Little Albert Conditioning

Back 11

~After 2 trials: reluctant to touch rat
~After 5 more trials: strong fear response to rat
~then conditioned fear generalized to other furry things

Front 12

In little Albert

UCS

Back 12

Banging of pipe

Front 13

In little Albert

UCR

Back 13

Fear/ alarm response to sound

Front 14

In little Albert

CS

Back 14

white lab rat

Front 15

In little Albert

CR

Back 15

fear/alarm response to rat

Front 16

Fear Conditioning
rats/shock
Basic procedure

Back 16

~Present tone/light (CS)
~immediantly shock (UCS)

Front 17

Fear Conditioning
Measured fear

Back 17

~freeze when shocked
~how much it disrupts rats ongoing activity

Front 18

anthropomorphizing

Back 18

~putting human characteristics onto an animal (scared)
~can't do this

Front 19

Infer rats emotional state from

Back 19

BEHAVIOR

Front 20

Conditioned Emotional Response (CER)

Back 20

~Conditioned Supression
~Technique for indirect measurment of conditioned fear
~Freezing (becoming inactive. stopping from pressing lever)
~specific to CS (tone)

Front 21

Supression Ratio

Back 21

~Quantitatively measures conditioned suppression
~greater levels of conditioned fear lower ratio values

Front 22

Eyeblink conditioning

Back 22

~Rabbits9Almost never blink)
~eyeblink is a reflex
Airpuff(UCS)-->eyeblink(UCR)
~if tone precedes airpuff
tone-->airpuff-->eyeblink
~learn to blink to tone
Tone(CS)--> eyeblink(CR)
(eyeblink from UCR to CR when puff removed)

Front 23

2 important eyeblink conditioning points

Back 23

1. CC requires pairing CS and UCS
2. Initial learning may NOT be drectly observable

Front 24

Taste Aversion Learning

Back 24

1.Learned from SINGLE trial
2.Long-delayed learning
~ need to be a delay
3.Novel and distinct

Front 25

Sign Tracking

Back 25

~autoshaping
~movement toward (possible contact with)a stimulus that signals the availability of food

Front 26

Ex. Sign tracking

Back 26

Pigeons peck at respinse key
when illumination of response key (CS)
reliably preceded delivery(UCS)
