1. Early Behaviorism:Pavlov, Watson and Guthrie (Chapter 2) Vengertsev Dmitry Questions, Important psychophysics – measurement of physical stimuli and their effectQuestions, Important psychophysics – measurement of physical stimuli and their effect
2. Agenda Goals:
What classical conditioning is
Emotions might be learned
Similarities and differences among Pavlov, Watson and Guthrie
Early Psychophysics
I. Pavlov: Classical conditioning and its phenomena
J. Watson: Behaviorism, Emotional Learning
E. Guthrie: One-shot learning theory
3. First Steps of Psychophysics W. James: Introspection is the self-observation and reporting of conscious inner thoughts, desires and sensations.
Scientific approach: Psychophysics
W. Wundt, G. Fechner tried to
find absolute threshold for
each sense – least amount
of stimulation required for
sensation
M. Weber law: noticeable
difference are a constant proportion
of a stimulus Describe an example!Describe an example!
4. Ivan Petrovich Pavlov Profound influence on
development psychology
Classical conditioning
is a form of associative learning
unconditioned stimulus (US)
+
unconditioned response (UR)
conditioned stimulus (CS)
+
conditioned response (CR)

5. Classical Conditioning Important to remember US UR CS CR – we will use it. Stuffed dog from The Pavlov Museum in Saint-Petersburg.Important to remember US UR CS CR – we will use it. Stuffed dog from The Pavlov Museum in Saint-Petersburg.
6. Classical Conditioning Theory Two different explanation of Learning:
Contiguity – for behavior to change it’s sufficient that two events be paired
Reinforcement – an effect that leads to learning (such as satisfaction of hunger) (details in Chapter 3)
7. Phenomena in Classical Conditioning Learning curve
Extinction and Recovery
conditioned associations are
remarkably durable
spontaneous recovery (after
some period of time)
Generalization
salvation at wide range of tones
Other important aspects of Pavlov’s work in conditioning theory. In conclusion add information from p.43. Strength of CR – amount of salvation. Examples.Other important aspects of Pavlov’s work in conditioning theory. In conclusion add information from p.43. Strength of CR – amount of salvation. Examples.
8. John Broadus Watson Profoundly influenced by Pavlov’s model of classical conditioning
Revolutionize American psychology
Behaviorism – observable aspects of behavior. It’s real goal is to provide the basis of control of human beings
Emotional Learning
Watson’s Environmentalism
9. Behaviorism Before Watson: Behaviorism is a study of the phenomena of consciousness
Watson: consciousness is an irrelevant concept. Behaviorists tried to limit psychology to the study of actual, observable behavior
The main goals of behaviorism:
to provide the basis for the prediction and control of human beings
to derive laws to explain the relationships existing among stimuli, responses and consequential conditions (reward, punishment)
10. Emotional Learning Little Albert
11-month-old boy
At the beginning showed no fear to great variety of objects and people
Everyday among other things he was given white rat toy
Touched white rat – loud sound. Albert didn’t cried, he tried again and again – each time was loud sound
A week later procedure was repeated. Rat and the loud sound were combined for 5 more times
Albert behavior change dramatically Say result and adultSay result and adult
11. Watson’s environmentalism Are humans primarily product of genetic makeup or are they developed according environment?
He was convinced that there are no individual differences at birth, people is function of their experience
Very popular ides in the United States at that time Some declarationsSome declarations
12. Watson’s behaviorism Exaggerating role of learning in determining the behavior and underemphasizing the role of heredity
He was more of a spokesman for behaviorism than a researcher
He popularized notion of environmental experiences
13. Edwin R. Guthrie Theory consisted of only a single law:
“When organism does something in one occasion, it will tend to do exactly the same thing if the occasion repeats itself”.
He claims that the full strength of the bond between stimulus and response is reached during the first pairing LAW Example with woman! And application to dogLAW Example with woman! And application to dog
