Learning Flashcards
what is the definition of learning?
a relatively permanent change in behaviour that occurs as a result of experience. A change must be immediate or delayed, actual or potential. Learning may be intentional or unintentional.
what is the definition of classical conditioning?
simple form of leaning, that is based on the repeated association of two different stimuli.
what as the phase before classical conditioning?
UCS——> UCR (in response to UCS)
CS ——-> no response
what is the phase during conditioning?
CS + UCS ——> UCR (in response to UCS)
what is the phase after conditioning?
CS ———> CR (in response to the CS)
what is a stimulus?
any event that produces a response from an organism.
what is a response?
a reaction by the organism to the stimulus.
what are the elements of classical conditioning?
UCS, UCR, CS, CR, NS
what is the unconditioned stimulus?
Any stimulus that produces an automatic reflex (UCR).
what us the unconditioned response?
The response which occurs automatically when the UCS is presented
what is the neutral stimulus?
It is neutral but through repeated association with the unconditioned stimulus it produces the same effect as the CS.
what is the conditioned response?
The new learned response which is produced by the conditioned stimulus (CS).
what is a conditioned stimulus?
The stimulus that originally does not produce any response but when paired with UCS it becomes the CS. and produces the CR
what are the processes in classical conditioning?
extinction, spontaneous recovery, stimulus generalisation, stimulus discrimination
what is extinction (CC)?
Gradual decrease in strength or rate of CR when UCS is no longer present.
Occurs because CS and CR are not always permanent.
Has occurred when CR no longer occurs after CS.
More complex behaviour take longer to extinguish.
what is spontaneous recovery? (CC)
Extinction is not always permanent.
Reappearance of CR when CS is presented following a rest (no CS) and the extinction of CR.
Doesn’t always occur.
Usually shorted lived and weaker than original.
what is stimulus generalisation? (CC)
Tendency for another stimulus (similar to CS) to produce response similar to CR.
CR may not be the same.
Greater similarity in CS, greater the similarity in responses.
what is stimulus discrimination? (CC)
Tendency for only one stimulus (CS) to produce a CR.
what is a conditioned reflex? how complex is it? What does it involve? is it inborn? what is an example?
simple.
A conditioned reflex is an automatic response that occurs as a result of a previous experience, or a learned reflex response.
involves little conscious thought (eg. Dim at theatres, stop talking).
Not inborn but learned.
It often involves anticipatory behaviour.
Looking at someone hen they call your name.
what is a conditioned emotional response? how complex is it? what is an example?
An emotional reaction that occurs when the autonomic nervous system produces a response to a stimulus that did not previously trigger that response (often a fear response).
eg. Albert B. Experiment
what did the Albert B experiment investigate? and what did they find?
Investigated the acquisition of fears.
Found that they can be acquired through classical conditioning
who was the participant of the Albert B experiment? why was he chosen?
11 month old named Albert B.
mother worked in Watson’s clinic.
Chosen because he was unemotional.
Watson thought he could not harm Albert
what was the procedure of the Albert B experiment?
tested to make sure he was capable of a fear response (UCR).
Placed in a room with a white rat within reaching distance (CS).
Albert showed no fear and played with the rat.
While playing with the rat an experimenter made a loud noise behind him (UCS).
Albert was shocked and scared and started to tremble.
The noise was made when he went near the rat.
He became afraid of the rat and cried when it came near him.
what were the conclusions of the Albert B experiment?
fear can be conditioned.
Fears were generalised to similar objects: rabbits, a dog, white fur coat, cotton balls and a Santa Mask.
what were ethical issues with the Albert B experiment?
his fears may have disappeared overtime but he probably suffered psychological harm.
Mother gave consent but it was not informed.
No harm principle was breeched.
Mother left job and Albert came too, he was not debriefed.
No code for ethics back then.
what is the definition of operant conditioning? what usually happens?
Operant conditioning is the learning process by which the likelihood of a particular behaviour occurring is determined by the consequences of the behaviour.
The organism will tend to repeat behaviours with desirable consequences and not repeat those with undesirable consequences.
what is an operant?
response or behaviour
what is the three-phase model of OC?
antecedent stimulus, behaviour and consequence
