Chapter 13: The Behavioural/Social Learning Approach Flashcards
John Watson’s life
- Was a fighter and a builder
- Had a lack of enthusiasm for contemporary standards
- Studied psychology because he preferred working with rats instead of humans
- Was forced out of the discipline after marrying his research assistant
start of behaviourism
Behaviourism was started by John B. Watson’s 1913 article titled “Psychology as the Behaviourist Views It”
main argument of behaviourism
- Argued that only the observable was reasonable subject matter for a science
- Thus, psychologists should only study overt behaviour
Watson on conditioning
Believed that a few key conditioning principles would suffice to explain almost any human behaviour
Watson on personality
Argued that personality is the end result of one’s history of conditioning
Watson on shaping infants
Claimed that given a dozen healthy infants, he could train them into any type of specialist
B.F. Skinner’s life
- Initially wanted to become a novelist, but failed to produce anything after two years of writing
- Studied psychology at Harvard and emersed himself in his studies
- Was not always as anti-Freudian as he is often described
Similarities between Skinner and Freud
- Created a projective test based on the vague sounds emitted by a phonograph early in his career
- Sought out the opportunity to go to psychoanalysis
- Agreed with Freud that people simply do not know the reason for many of their behaviours, even though they think they do
what did Skinner call his approach?
radical behaviourism
radical behaviourism
- a less extreme version of the position Watson advocated for
- argued that people do not know the reason for their behaviour
Skinner on inner thoughts and experiences
- Acknowledged the presence of thoughts and inner experiences
- Rejected the use of inner states as explanations of behaviour in favour of observable external events
Skinner on the causes of behaviour
- Challenged the extent to which we can observe the inner causes of behaviour
- Argued that we simply respond to environmental demands
Skinner on happiness
Described happiness as a byproduct of operant reinforcement
Skinner on dignity and morality
dignity and inner moral decisions are illusions because we simply respond to environmental demands
discovery of classical conditioning
Discovered by Ivan Pavlov in Russia
classical conditioning
Learning resulting from pairing a conditioned stimulus with a new, unconditioned stimulus
how does classical conditioning begin?
with an existing stimulus-response association called an unconditioned stimulus and an unconditioned response
example of an existing S-R association
salivating in the presence of food
how does a conditioned response develop?
when the unconditioned stimulus is paired with a conditioned stimulus
example of a conditioned S-R association
salivating in the presence of a bell, after it has been repeatedly paired with food
second-order conditioning
the process of building one conditioned S-R associated with another
example of second-order conditioning
pairing a green light with the bell to generate salivation
Pavlov on behaviour
We are unaware of many S-R associations that influence our behaviour
anxiety and classical conditioning study
participants were made to feel anxious and then asked to sit in a waiting room with a stranger. Although the two did not interact, participants reported unfavourable impressions of the other person
extinction
the gradual disappearance of the conditioned S-R association
limitations of classical conditioning
- The persistence of new S-R association requires occasional pairing or reinforcement of unconditioned and conditioned stimuli
- Extinction
- Impossible to create certain S-R bonds
discovery of operant conditioning
Discovered in the U.S. by Edward Thorndike
operant conditioning
Learning resulting from the response an organism receives following a behaviour
the law of effect
behaviours are more likely to be repeated if they lead to satisfying consequences and less likely to be repeated if they lead to unsatisfying consequences
how does operant conditioning begin?
Begins with the behaviours an organism emits spontaneously
reinforcement
a consequence that increases the frequency of a behaviour that precedes it
punishment
a consequence that decreases the frequency of the behaviour that precedes it
positive reinforcement
the presentation of a reward
effect of positive reinforcement
increases behaviour
negative reinforcement
the removal or lessening of an unpleasant stimulus
effect of negative reinforcement
increases behaviour
extinction
the removal of the reward
effect of extinction
Decreases behaviour
punishment
giving an aversive stimulus following behaviour or taking away a positive stimulus
effect of punishment
Decreases behaviour
