Cards

Term
behaviorism
Definition

belief that study is based on observable behavior, not the mind, and that behavior should be understood in terms of its relationship to observable events in the environment, rather than hypothetical

(stimulus and response) 

Term
reflex
Definition

automatic response to a stimuls (specific)

ex: startle reflex, tap nerve in knee and it kicks 

Term
habituation
Definition
when an unlearned reflexive response diminishes with repeated presentation of the stimulus
Term
classical conditioning
Definition

learning experience when a neutral stimulus (conditioned stimulus) comes to elicit a reflexive response though its being paired with another stimulus (unconditioned stimulus) that already elecits that reflexive repsonse

 -->Pavlov dogs with bell and meat

Term
habituation
Definition

when an unlearned reflexive response diminishess with repeated presentation of the stimulus

-->simplest form of learning, "change in your behavior as a response/experience with your environment 

Term
unconditioned reflex              
Definition
original, unlearned association
Term
conditioned reflex
Definition
new association to stimulus
Term
pairing
Definition
repeated presentation of unconditioned stimulus and conditioned stimulus nearly simultaneously
Term
extinction
Definition
when a conditioned stimulus is presented without unconditioned stimulus, the conditioned response diminishes
Term
spontaneous recovery
Definition
when a conditioned response returns due to mere passage of time or recurrence of unconditioned stimulus
Term
generalization
Definition
after conditioning, animals would show the conditioned response to stimuli that resembled that stimulus
Term
discrimination training
Definition

generalization between two stimuli can be abolished if the response to one is reinforced while the response to the other is extinguished

Term
Classical Conditioning Stimulus Stimulus Association
Definition
animal learns association between both stimuli, does not learn direct response to stimuli response
Term
Fear conditioning, two unconditioned stimuli for fear in infants
Definition
emotion of fear can be conditioned in human beings, loud noises and sudden loss of support
Term
conditioned drug response
Definition

direct effect followed by a compensatory reaction that counteracts the direct effect and tends to restore the normal bodily state

Feel opposite of what drug does in its absence (withdrawal/comedown) 

Term
drug tolerance
Definition
decline in physiological and behavioral effects taht occur with some drugs when they are taken repeatedly
Term
conditioned reactions as causes of drug relapse after withdrawel
Definition

conditioned stimulus elicits a response that is opposite to the drug response. Conditioned compensatory reactions contribute to drug tolerance and drug relapse.  Absence of conditioned stimuli, overdose can occur

ask tracey 

Term
Operant Conditioning
Definition
training or learning process by which consequence of behavioral response affects the future rate of production of that response
Term
operant response
Definition
operate on world to produce some effect (bring change in the environment)
Term
Thorndike's Law of Effect
Definition

responses that produce a satisfying effect in a situation become more likely in that situation, responses taht produce an unsatisfying effect become less likely

(cats in box, after many successful exits continue to press lever more rapidly to access food) 

Term
reinforcer
Definition
reward or satisfaction
Term
shaping
Definition

incremental reinforcement of behaviors that increasingly approximate target behavior

(you're getting warmer) 

Term
continuous reinforcement
Definition
every operant response is reinforced
Term
partial reinforcement
Definition
only some operant responses are reinforced
Term
fixed ratio schedule
Definition
reinforcer that occurs after every nth response
Term
variable ratio response
Definition
fixed ratio schedule except that teh number of responses required before reinforcement varies unpredictable around some average
Term
fixed interval schedule
Definition
fixed period of time must elapse between one reinforced response and the next
Term
variable interval response
Definition
fixed interval schedule except taht the period must elapse before a response will be reinforced varies unpredictable around some average
Term
partial reinforcement extinction
Definition
extinction occurs mroe slowly after partial reinforcement than after continuous reinforcement (Vegas slot machines)
Term
positive reinforcement
Definition
arrival of some stimuls following a response makes the response more likely to occur
Term
positive reinforcer
Definition
the food that occurs when the arrival of some stimulus following a response makes the response more likely to recur
Term
negative reinforcement
Definition
the removal of some stimulus following a response makes the response more likely to occur
Term
negative reinforcer
Definition
stimulus removed that follows a response that will now be more likely to occur (electric shocks, loud noises, unpleasant company...)
Term
punishment
Definition
process which the consequence of a response decreases likelihood that response will occur
Term
positive punishment
Definition
arrival of a stimulus, such as electric shock, decreases likelihood that the response will occur again
Term
negative punishment
Definition
removal of a stimulus, such as taking food away from hungry person, which decreases likelihood that that the response will occur again
Term
discrimination training, ex, essence?
Definition

operant response can be brought under control of a more specific stimulus than the entire inside of skinner box (respond to tone by pressing lever)

essence:reinforce the animal's response when a specific stimulus is present and to extinguish the response when the object is not

Term
means ends relationship, ex
Definition

animal's knowledge or belief that a particular response, in a particular situation, will have a particular effect

ex: knowledge that lever press will now bring a certain kind of food, decision to press lever or not, depending on whether the food is desired (stimulus-response_

Term
reward contrast effects
Definition
animal learns to expect a certain kind of reward for making a certain kind of response
Term
negative contrast effect
Definition
shift from strong to weak reinforcer show a sharp drop in their response rate, to a slower rate than that of the rats that had been in the weak reinforcer position all along
Term
positive contrast effect
Definition
shifting from weak to a strong reinforcer show an increase in their response rate, to a higher rate than that of the rats who had been in the strong-reinforcer condition all along
Term
observational learning
Definition
learniny by watching others
Term
stimulus enhancement     
Definition
increase in attractiveness of the object that the observed individual is acting upon
Term
goal enhancement, ex
Definition

increased drive to obtain rewards similar to what the observed individual is receiving

kitten sees mom push lever for food (stimulus enhancement) and then sees pellets come out (goal enhancement) 

Term
imitation
Definition
instances in which the observer reproduces the specific actions of the observed individual
Term
why people observationally learn/ what they learn
Definition

people actively observe the behavior of other people to gain knowledge about the kinds of things that people do in particular situations

Term
how can we predict the form  of the controlled response?
Definition
CR (conditioned response) is allowing the organism to prepare for the UCS (unconditioned stimulus)-->expectancy effect
Term
food aversion
Definition

optimal delay between the conditioned and unconditioned stimuli (feeling sick long after tasting food)

Term
food preference
Definition
body naturally craves what's lacking (with exception of sugar laced foods)
