Behaviourism and
the cognitive
revolution
- Behaviourism has three philosophical claims:
methodological behaviourism, psychological
behaviourism, and philosophical or logical
behaviourism. Skinner adopted all 3 and claimed
radical behaviourism
- Pavlov
- First key behaviourists influenced by Darwin.
External stimuli affects behaviour and there is no
"internal world" of consciousness.
- Criticisms of behaviourism
- Genes can strongly influence behaviours, although
conditioning can amplify/inhibit these. Prenatal
environments may also affect behaviours.
- Instinctive drift (Breland & Breland) - tendency to
revert to unconscious and automatic behaviours.
- Some behaviours are harder
to condition than others
- Thorndike
- Functionalist that proposed the law of
exercise and disuse, and the law of effect
- The law of exercise and disuse - repeated
exercise of a response strengthens its
connection
- The law of effect - responses that
produce a satisfying effect are more
likely to be repeated
- Basis of operant conditioning, learning that
occurs through rewards and punishments
- British associationism
- Hartley
- Proposed that psychological processes emerge from the body as a
neurological response. The body and the mind function together and
there is no separate mental matter.
- He proposed the physiological
associationist model of the mind - nerves
vibrate and transmit to other nerves,
giving rise to action.
- Bain
- Proposed the mind and body occur together
without a causal relationship. Claimed
hedonism and was a voluntarist
- Watson
- Little Albert study to
show conditioned fear.
- John Watson (1913) -
psychology as the
behaviourist views it
- Objectives of behaviourism - adjustment and
maladjustment, phylogenetic continuity, and
determination of behaviour
- Behaviours can be measured and changed
and all behaviours are acquired through
conditioning
- Preparedness theory criticises this, , explains
how some people are born ready to fear
certain types of stimulus
- Harris, 1979 - what happened to little albert
- Seligman. 1971
- Watson and Rayner, 1920
- Conditioning of an emotional response, Little Albert
- Hull
- Looked at organismic variables,
aka motivations. Moved beyond
S-R relationships
- Reaction potential to a stimulus (sER), Habit
strength (sHr), and drive (D)
- Drive reduction theory (sER = sHr x D)
- Motivation arises as a result of biological
needs. Humans will repeat any behaviour
they know reduces the drives.
- Organismic variables are
internal forces and
influences that influence an
organisms behaviour
- Hull, 1949
- Tolman
- We cannot get rid of mentalist terms and cognitive
maps etc. He saw evidence of goal directed behaviours
in animals and cognitive processes
- Looked at maxe learning in rats, arguing they create a
cognitive map and take part in latent and expectancy
learning (cognitive learning requires acquired
expectancies)
- Skinner
- Proposed two accounts of learning: Type S
(Classical conditioning) and Type R (Operant
conditioning)
- Cognitive model of the mind
- Gestalt psychology
- Rejected Bundle Hypothesis, arguing that
the whole is greater than the sum of its
parts (holism)
- Rejected constancy hypothesis, arguing that
percept is rationally determined, and depends
on the relationships between stimuli
- Law of Pragnanz - we are
innately driven to
experience things in as
orderly, simple fashion as
possible
- Phi and beta - our
perceptions go beyond
the physical evidence
- The 5 Gestalt laws -
Similarity, closure,
proximity, symmetry,
and continuity
- Bartlett
- Schema theory
- Studied recall in "war
of ghosts" study
- Memories can be constructive. In his study
he found that p's recalled what they
thought should happen rather than what
did
- Craik
- The mind creates mental
models of reality
- Piaget
- Developmental psychology
and genetic epistemology
- He assumes the use of cognitive structures,
we acquire more complex means of reasoning
with maturity.
- Compared to behaviourism, he
assumes learning changes as a
function of development, whereas
behaviourism assumes learning is
constant
- Elsewhere
- Turing
- Proposed the Turing machine which
states simple operations can give ride to
any complex functions
- McCulloch and Pitts
- Developed a test for
whether a computer
could think
- Searle's Chinese
room showed a
problem for this
- Weiner
- Invented cybernetics
- Crucial to information processing and cognitive
models of the mind
- Shannon
- Information theory
- Mathematical model of communication, proposing
information can be measured in terms of
uncertainty.
- All of these other theories were imported into psychology to explain the
functioning of the mind. The brain is seen as an information processing
device, taking input from the world and processing it, deciding which
behaviour is the best output. This led to a computational theory of mind.
- Critical evaluation of the cognitive
revolution
- Chomsky
- Critiqued Skinner. He pointed out that the flexibility of
language means that conditioning has little predictive
value, and that imitation is a poor basis for language
- Argued language ability has a genetic basis and
is innate. Through development, children adopt
different parameters to learn new languages
(universal grammar)
