chapter 7: learning Flashcards
change in behaviour due to experience, a relatively permanent change in behaviour not due to drugs, maturation / development, injury, or disease
learning
any observable action (words, gestures, responses) that can be repeated, measured, and are affected by a situation to produce or remove some outcome, also refers to biological activity (cellular level)
behaviour
a term for something you’re born knowing how to do, not a result of learning
innate
automatic and simple responses, a type of stimulus-response relationship that involves behaviours occurring automatically in response to its stimulus
reflexes
how we learn what happens when we do something
operant conditioning
when we learn something by watching others
social (vicarious) learning
Ivan Pavlov
- studied how dogs digest food in 1900s by examining how much dogs drooled when they receive meat powder
- noticed drooling associated with other actions leading up to feeding the dogs, and discovered reaction that was measurable and learned in the presence of triggers
- classical conditioning
involves associating two events that occur together, one seemingly insignificant event signals an important event, a conditioned stimulus indicates the presence or absence of a conditioned stimulus (one way in which we develop fears)
classical conditioning / Pavlovian conditioning
can be anything in the environment that we can detect, measurable, and can evoke a response or behaviour
stimulus
a type of stimulus in Pavlovian conditioning in which a biologically important event requires no conditioning to effect behaviour (stimulus that leads to automatic response)
unconditional stimulus
an innate reflex, biologically important response occurs because of an unconditional stimulus
unconditional response
an event that requires learning to be meaningful and is only meaningful because the event tells us something about the unconditional stimulus (triggers conditional response)
conditional stimulus
a conditional reflex, a learned response that occurs to the conditional stimulus in preparation for the unconditional stimulus
conditional response
a descriptor for behaviour in Pavlovian conditioning which indicates a response to a stimulus is involuntary
elicits
refers to the probability of learning occurring if the unconditional stimulus does or does not occur
conditional
a stimulus that does not naturally elicit a response, does not indicate whether a unconditional stimulus will occur
neutral stimulus
a type of Pavlovian conditioning in which the conditional stimulus indicates that an unconditional stimulus will occur (positive correlation between the CS and US)
excitatory conditioning
the US occurs within a few seconds of the start of CS, most effective excitatory conditioning procedure
short-delayed conditioning
the US occurs after the CS has been there for a while, doesn’t pinpoint well exactly when the US will occur
long-delayed conditioning
the US occurs minutes or hours after the CS has stopped, the events in this procedure are so far apart they seem to have no relation
trace conditioning
a type of Pavlovian conditioning in which the CS indicates that no unconditional stimulus will occur (negative correlation between the CS an US), one event signals that another will not occur
inhibitory conditioning
the US occurs with the start of the CS (CS and US overlap completely)
simultaneous conditioning
the US occurs a few seconds before the start of the CS, so the CS indicates no US will occur
backward conditioning
occurs when two factors appear causally related to one another but are not
spurious correlation
a learned response where animals avoid eating the food in the future that is associated with illness
taste aversion
gradual weakening of a conditioned response that results in the behaviour decreasing or disappearing, loss of associative strength as an increasingly weaker conditional response (CS appearing without US will cause extinction)
extinction
involves repeatedly presenting a conditional stimulus without an unconditional stimulus
Pavlovian extinction
involves intense fear, agitation, and possibly social isolation
post-traumatic stress disorder (PTSD)
a learning phenomenon in which a stimulus that predicts the absence of an otherwise expected outcome comes to control an organism’s responding (generally arbitrary stimuli) (no fear)
conditioned inhibitors (safety signals)
a type of stimulus that is something you like and for which you will work
pleasant/appetitive stimuli
a type of stimulus that is something you don’t like and for which you won’t work
unpleasant/aversive/noxious stimuli
image set contains images meant to elicit an emotional response from the research participants (categorized as pleasant, neutral, or unpleasant)
international affective picture system (IAPs)
involves responding similarly to conceptually or physically similar stimuli (an event that has not been paired with US also elicits or causes the CR) (tends to happen with phobias)
stimulus generalization
involves responding differently to different events, opposite of stimulus generalization, CR only occur when the original CS is introduced
stimulus discrimination
a neutral stimulus is systematically and repeatedly paired with a CS that reliably elicits the CR
higher-order conditioning
what is the difference between typical Pavlovian conditioning and higher-order conditioning
Pavlovian conditioning: neutral stimulus -> unconditional stimulus
higher-order conditioning: (already paired neutral stimulus -> unconditional stimulus) neutral stimulus -> conditional stimulus
an approach to science that focuses on how we learn new behaviours, and how those behaviours change across different situations
behaviourism
little Albert experiment
conducted by John B. Watson (behaviourist), involves developing a Pavlovian fear response to furry, white objects in a 9-month-old baby
exposure therapy used to treat extreme aversions through a combination of graded exposure and relaxation (developed by Joseph Wolpe)
systematic desensitization
intense, unrealistic fears directed toward people, objects, or situations
phobias
describes situations in which we can choose among different options based on our previous experiences (we learn that our behaviour has consequences) (reward and punishment)
operant (instrumental) conditioning
Edward Thorndike
known for his work with cats in puzzle boxes (required a certain set of behaviours to open a door)
a method that involves several attempts to find a solution to a problem
trial-and-error learning
the process of interacting with some response option that has an effect on the environment
instrumental learning
behaviours that lead to satisfying outcomes are likely to be repeated, whereas behaviours that lead to undesired outcomes are less likely to recur
law of effect
“stamping in”, means that we associate a situation with behaviour when that behaviour leads to something pleasant
satisfaction
