with salivating dogs
Unconditioned
Stimulus
(US)
A stimulus that naturally
evokes a response or
reflex
Conditioned
Stimulus
(CS)
A stimulus that does not
naturally evoke a
response, but can acquire
the ability to elicit the
response
CATEGORICAL LEARNING
A category is defined by a number of features. An object
belongs to a category only if it has certain defining
features.
Through categorical learning, the brain creates
appropriate categories and can decide to which
category belongs a certain object.
… is a cat!
This object…
PAVLOV’S EXPERIMENT
A QUESTION OF ETHICS
In 1920, little Albert, an eleventh month old orphan, learned to
fear a rabbit.
Unconditional stimulus: loud noise. The noise is so loud that it
causes a fear response.
Conditional stimulus: little rabbit. The rabbit originally doesn’t
cause a fear response.
Initially, the sound
causes fear…
But if you present
simultaneously
and
But not the rabbit
many times, then
… the rabbit also
causes fear!
