what is unlearned association
experiencing stimulus automatically triggers response
what is an unconditioned stimuli
a stimuli that can automatically elicit unlearned unconditioned responses
- because of pre existing unlearned association
why do USs often elicit unconditioned responses
because the have motivational value
what is an unconditioned response
an involuntary reflex or response to a US, which can be overt or internal
what is a conditioned response
a previously neutral stimulus that, after being paired with a US, comes to trigger a conditioned response
what is a conditioned response
the response elicited by the CS alone; it is an indirect elicitation of the UR and reflects the animal ‘knowing’ the US is coming
is classical conditioning S-R or S-S learning
S-S learning
- the CS activates the mental representation of the US, which then leads to the response
- it is not a direct S-R link
what is the devaluation thought experiment
what is the stimulus substitution theory
the CS acts as a substitute for the US, often causing the CR to closely resemble the UR e.g pigeons pecking a light as if it were a grain
what is evaluative conditioning
when the motivational properties of a US transfer to the CS. this is frequently used in advertising by pairing brands with positive images
what is second order conditioning
what is sensory preconditioning
what did Jenkins and Moore find
what is a criticism of Hull and Thordike
Hull argued all learning was S-R and required a visible response/reinforcer
- sensory preconditioning proved Hull wrong by showing learning can happen between neutral stimuli without immediate reinforcement to behaviour
how is appetitive conditioning measured
by conditioned approach - the graph goes up
- head entries into a food hopper
how is aversive conditioning measured
conditioned suppression
- freezing
- graph goes down as it suppressed other behaviours like lever pressing
what is the suppression ratio formula
what is extinction
what is spontaneous recovery
after a delay, the CR returns, proving the original association was not erased but merely masked by new inhibitory learning
what is conditioned inhibition
what is the motivational value of inhibitors
