What is learning?
Learning: Lasting change as a result of practice, study, or
experience. It has to be inferred from behaviour.
Two types of learning
- Non-associative learning - learning that does not involve forming
associations between stimuli; it is change resulting from
experiences with a single sensory cue - Associative learning – a change as a result of experience where two
or more stimuli become linked
Non-Associative Learning
- Habituation - weakening of response to a stimulus after repeated
presentation - Dishabituation - a form of non-associative learning whereby there is a
recovery of attention to a novel stimulus following habituation - Sensitization - a strong stimulus results in an exaggerated response to
the subsequent presentation of weaker stimuli
Associative Learning:
Associative learning - connections are formed
more stimuli
- Classical conditioning
- Operant conditioning
between two or
Classical Conditioning
- Unconditioned stimulus (US) - a stimulus that on its own elicits a
response (i.e., food) - Unconditioned response (UR) - a physical response elicited by an
unconditioned stimulus; it does not need to be learned (i.e.,
salivation)
Ivan Pavlov’s Dog
Pavlov’s experiment for collecting and measuring salivation in dogs The
hungry dog is placed in a harness and given a bowl of meat powder. A tube
from the salivary gland collects the saliva, which is measured and
recorded.
Stimuli and Response in Classical Conditioning
- Unconditioned stimulus (UCS): a stimulus that elicits a response from an
organism naturally (i.e., without conditioning)
– Example: meat powder presented to a dog - Unconditioned response (UCR): an unlearned response to an unconditioned
stimulus
– Example: salivation in response to meat powder - Orienting reflex: an unlearned response in which an organism attends to a
stimulus
– Example: dog looking in the direction of bell/light (CS)
Major Conditioning Processes:
- Acquisition - the initial learning of the stimulus-response
relationship; the most rapid acquisition followed by the
strongest response is a half a minute delay between CS and
US - Extinction - reduction of a conditioned response after
repeated presentations of the conditioned stimulus alone - Spontaneous recovery - re-emergence of a conditioned
response some time after extinction has occurred
Extinction and Spontaneous Recovery
E.g., Child learns to associate sound of car entering driveway with Parents
coming home
* Extinction: the process by which conditioned stimuli lose the ability to elicit
conditioned responses
*The conditioned stimuli are no longer associated with unconditioned stimuli.
e.g., sound of car (CS) entering driveway
Child no longer happy as has seemingly forgotten association of CS with UCS
*Actually, Extinction inhibits the response;
* The CR response available under right conditions
- Spontaneous recovery: the recurrence of an extinguished response as
a function of the passage of time - Spontaneous recovery helps organisms adapt to situations that
recur from time to time.
e.g., After long period, of time child hears sound of car (CS),would
associate
with sounds of parent’s homecoming and is happy - Something had changed when no car entered the driveway for so
long. - Spontaneous recovery helps organisms adapt to situations that
recur time to time.
Generalization and Discrimination
- Generalization: the tendency for the conditioned response to be
evoked by stimuli that are similar to the conditioned stimulus - Example: If you are bitten by a dog, you may fear all dogs.
- Discrimination: the tendency for the conditioned response to be
evoked by only the conditioned stimulus and not by similar stimuli - Example: If you are bitten by a Rottweiler, you may fear Rottweilers
but not poodles.
Major Conditioning Processes
- Stimulus discrimination - an organism learns to emit a specific
behaviour in the presence of a stimulus, but not in the presence
of stimuli similar to the original stimulus - Higher-order conditioning - occurs when a previously
conditioned stimulus functions as if it were an unconditioned
stimulus for further conditioning
Phobia
persistent, irrational or obsessive fear of a specific object
or situation that may arise as a result of fear conditioning
Systematic desensitization
a process used to condition extinction
of phobias through gradual exposure to the feared object or
situation
Classical Conditioning and Taste Aversion
Conditioned taste aversion - a form of classical conditioning
where a previously neutral stimulus (often an odour or taste)
elicits an aversive reaction after it’s paired with illness (nausea)
Operant Conditioning and behaviourism
- Behaviourism - the systematic study and manipulation
of observable behavior
o Founded by B.F. Skinner - Organisms don’t simply respond to the environment, but rather they
exert influence (or “operate”) on it. - Behaviours that are followed by favourable consequences will likely
be repeated.
