Learning Flashcards
Learning
any relative permanent change in behaviour as a result of experience
Classical Conditioning
an organism learns to associate a neutral stimulus with a biologically relevant stimulus results in a change in the response to the previously neutral stimulus
Unconditioned Stimulus (US)
Stimulus that elicits a reflexive response without learning
Unconditioned Response (UR)
Reflexive unlearned reaction to an unconditioned stimulus
Conditioned Stimulus (CS)
once neutral stimulus that later elicits a conditioned response
Conditioned Response (CR)
learned response that occurs to the conditioned response
Acquisition
a response is established
Extinction
reduction of a conditioned response when a conditioned stimulus and unconditioned stimulus no longer occur together
Spontaneous Recovery
reoccurrence of a previously extinguished conditioned response, after some time has passed since extinction
Generalization
response that originally occurred for a specific stimulus also occurs for different but similar stimulus
Discrimination
Organism learns to respond to one original conditioned stimulus but not to new stimuli that may be similar to the original stimulus
Conditioned emotional responses
consist of emotional and psychological responses that develop to a specific object or situation
preparedness
the biological predisposition to rapidly learn a response to a particular class of stimulus
Conditioned taste aversions
acquired dislike or disgust for a food or drink because it was paired with illness
latent inhibition
frequent experience with a stimulus before it is paired with a unconditioned stimulus makes it less likely that conditioning will occur after a single episode of illness
operant conditioning
type of learning which behaviour is influenced by consequences
Reinforcement
event or reward that follows a response increases the likelihood of that response occurring again
law of effect
responses followed by satisfaction will occur again in the same situation whereas those not followed by satisfaction become less likely
reinforcer
stimulus that is contingent upon a response and that increases the probability of that response occurring again
punishment
process that decreases the future probability of a response
punisher
stimulus that is contingent upon a response and that results in a decrease in behaviour
positive reinforcement
strengthening of behaviour after potential reinforcers such as praise, money or nourishment follow that behaviour
negative reinforcement
involves the strengthening of behaviour because it removes or diminishes a stimulus
avoidance learning
type of negative reinforcement that removes the possibility that a stimulus will occur
Escape learning
occurs if a response removes a stimulus that is already presented
positive punishment
behaviour decreases in frequency because it was followed by a particular usually unpleasant stimulus
negative punishment
behaviour decreases because it removes or diminishes a particular substance
shaping
successive approximations of a specific operant response
chaining
involves linking together 2 or more shaped behaviours into a more complex action or sequence of actions
applied behavioural analysis
using close observation, prompting and reinforcement to reach behaviours often to people who experience difficulties and challenges owing to a developmental condition
primary reinforcers
reinforcing stimuli that satisfy basic motivational needs
secondary reinforcers
consist of stimuli that acquire their reinforcing effects only after we learn that they have value
schedules of reinforcement
rules that determine when reinforcement is available
continuous reinforcement
every response made results in reinforcement
partial (intermittent) reinforcement
only a certain number number of responses are rewarded or certain amount of time must pass for rewards
latent learning
learning that is not immediately expressed by a response until the organism is reinforced to do so
observational learning
changes in behaviour and knowledge that result from watching others
