Behaviorists believe that when we
are born our mind is a 'tabula rasa'
= blank slate.
We are not born with in-built mental content;
internal events such as thinking and emotion do
not drive our behaviour.
Instead, the belief is that all of our behaviour is learned from
interactions with the environment:
We do not think about behaviour, we just respond
passively to different types of enviromental
stimuli.
Central to this assumption is the idea of nurture over nature.
-the view that social and
environmental factors have the
greatest influence on behaviour
-ignores factors of
genetics, physiology &
evolution.
Environmental determinism - our behaviour is determined
by the environment that we grow up in.
For example, when we are young we might associate dentists with
pain and anxiety from a young age. Accodring to behaviourists,
such expericence may mean that as an adult you fear the dentists.
Assumption 2: Behaviour is learned through conditioning
There are two types of conditioning in the behaviourists approach:
classical and operant conditioning.
Classical conditioning
It tends to involve involuntary
behaviour.
Two stimuli are linked together to produce a new
learned response in a person/animal.
-involves learning through association between
two stimuli that occur together in time.
Ival Pavlov first described the following
process from his observations of salivation
if dogs.
-explains how we learn
behaviour through association
Operant Conditioning
Largely about voluntary behaviour -
behaviour we actively choose & think
about.
-explains how voluntary behaviour is
learned
-based around the idea of reinforcement
(rewards)
There are two types of reinforcement:
Positive
-a pleasant stimulus received after a
behaviour is performed.
Negative
-escaping something
unpleasant.
B.F.Skinner (1938) demonstrated via the Skinner Box that an
animal can learn to behave in certain wayy due to being
rewarded (positively reinforced) with food.
Assumption 3: Humans and animals learn is similar ways
The laws of learning are the same
for both humans and animals.
We are able to study animal learning in a lab and
make generalisations about human behaviour.
For example, Pavlov developed the principles of
classical conditioning with dogs, where he showed
how thet could be conditioned.
The same principles have been applied to
humans in behaviourist therapies, to help
people overcome problems e.g. phobias.
In systematic desensitisation, the client will learn to
associate the phobic object with the feeling of
relaxation instead of anxiety.
Similarly, operant conditioning principles that were developed in
the lab with animals (e.g. Skinner's research with rats) are applied
in many contexts to help shape human behaviour, for example, in
education and prisons.
