Count the no. drops of saliva produced in
response to food/ presence of food-giver/
sounding of signal
Classical conditioning
Individuals
Ivan
Pavlov
Vladimir Bekhterev
Types of stimuli
Unconditional stimulus
Stimulus which produces an
innate, automatic and
reflexive response
Conditioned stimulus
A newly introduced
stimulus which has been
associated with an
unconditional stimulus to
gain a desired response
Neutral stimuli
A stimulus with no automatic
response association, that is paired
repeatedly with an unconditional
stimulus to teach association
Types of response
Conditioned response
Unconditional response
Higher order
conditioning
Acquisition
US --> UR
US + NS --> UR
Repeat
NS = CS
US + CS --> UR
CS --> CR
Same behaviour
NS --> NR
How long does CC last?
Extinction
If CS is presented
too often without
US, CR decreases
If too long passes without
association reinforcement,
the conditioned behaviour
is unlearned
Spontaneous recovery
After rest, the CR may
seemingly return
Often diminished
Extinction occurs more
rapidly with each
successive rest/recovery
Specificity of association
Depending on the similarity to the CR,
another stimuli may successfully elicit
the conditioned response
generalisation
context and presentation of
similar stimuli to CS
Usefulness of CC
Protective learned aversion
conditioned taste aversion
Hebb rule
neurons that fire together, wire together
Neuronal strengthening
When US and NS are paired, both relevant neurons
repeatedly fire simultaneously, strengthening the
relevant neuron for the NS 's connection with the
response neuron, this is further strengthened when
just the CS is triggered to gain the response.

Law of effect
Behaviour followed by
pleasant experience is
likely to be repeated
Behaviour followed by
unpleasant consequences
will likely cease
Reinforcement
Maintenance
of behaviour
Increasing presence
of behaviour
Punishment
control of
behaviour through
consequences
Reduction of
behaviour
Elimination
of behaviour
Reinforcement schedules
Continuous
Reinforcement happens every
time the behaviour occurs
Partial
Reinforcement only occurs some of
the time when behaviour occurs
Fixed interval
Reinforcement occurs after a
fixed period of time,
regardless of performance
rates of behaviour
Slowest learning
reinforcer
Variable interval
Gap between
reinforcement
can change
Slow gradual learing
Fixed ratio
every x no. times
behaviour is achieved,
reinforcement occurs
Learn gradually,
Variable ratio
Reinforcement
happens after
varying times
Learn fast, sustain
Insight
A moment of realisation of an
intention, or purpose to tasks
that should theoretically lead to
correct subsequent completion
Instrumental conditioning
Types of consequence
Positive
Addition
Negative
Removal
Types of reinforcement
Primary
Direct satisfaction of
a need or response
Secondary
No intrinsic value, but
can be used to acquire
primary reinforcers

Response
Changes in the neural

particular behaviour
Learning how to modify

The process of learning
to identify and
