occurs whenever exspirence or practice results in a relativley permanent change in behavior
Term
Uncondition stimulus (US)
Definition
Is an event that automatically elicits a certain reflex reaction
Term
Unconditioned response (UR)
Definition
a response that takes place in an organism when ever and unconditioned stimulus occurs.
Term
Conditioned stimulus (CS)
Definition
In classical conditioning, the conditioned stimulus is previously neutral stimulus that, after becoming associated with the unconditioned stimulus, eventually comes to trigger a conditioned response.
Term
Conditioned response
Definition
In classical conditioning, the conditioned response is the learned response to the previously neutral stimulus. For example, let's suppose that the smell of food is an unconditioned stimulus, a feeling of hunger in response the the smell is a unconditioned response, and a the sound of a whistle is the conditioned stimulus. The conditioned response would be feeling hungry when you heard the sound of the whistle.
Term
Pavlovonian conditioning
Definition
The type of learning in which a response naturally elicited by one stimulus comes to be elicited by a different, formerly neutral, stimulus
Term
intermitten pairing
Definition
pairing the conditioned stimulus and the unconditioned stimulus on only a portion of learning trials.
Term
Preparedness
Definition
a biological readiness to learn certain assocations because of their servival advantages
Term
Conditioned taste aversion
Definition
conditioned avoidence of certain foods even if there is only one pairing of conditioned and unconditioned stimulus
Term
Operant conditioning
Definition
the type of learning in which the behavoirs are emitted to earn rewards or avoid punishment
Term
operant behavoirs
Definition
behaviors designed to operate on the enviroment in a way that will gain something desired or avoid something pleasant
Term
Operant conditioning
Definition
the type of learning in which the behavoirs are emitted to earn rewards or avoid punishment
Term
reinforcers
Definition
a stimuli that follows a behaviorand and increases the likelihood that the behavior will be repeated
Term
Punishers
Definition
stimuli that follows a behavior and decreases the likelihood that the behavoir will be repeated
Term
Thorndikes Theory
Definition
behavior consistantly rewarded will be " stamped in" and behavior that brings about discomfort will be "stamped out"
Term
skinner box
Definition
a box offten used in operant conditioning of animals; it limits the available responses and thus increases the likelihood that the desired response will occur
Term
shaping
Definition
reinforcing successive aproximations to desired behavior.
Term
positive reinforcers
Definition
events whose presence increases the likelihood that ongoing behavior will recur.
Term
negative reinforcers
Definition
events who reduction or termination increases the likelihood that ongoig behavior will recur
Term
Punishment
Definition
Any event that decreases the likelihood that the ongoing behavior will recur.
Term
avoidence traing
Definition
learning a desirable behavior to prevent the occurance of something unpleasant, such as punishment
Term
biofeedback
Definition
The use of electronic monitoring of an automatic bodily function to train someone to acquire voluntary control of that function
Term
Neurofeedback
Definition
a biofeedback that technique that monitors brain waves with the use of an EEG to teach ppl to gain voluntary cotrol over over their brain wave activity
Term
contingency
Definition
a reliable if-then relationship between two events, such as CS and US.
or when one event relies on the other
Term
Blocking
Definition
a process whereby pior conditioning prevents conditioning to a second stimulus even whent the two stimuli are presented simultaneouly
Term
schedual of reinforcement
Definition
in operant conditioning the rule for determining when and how often reinforcers will be delivered
Term
fixed interval
Definition
a reinforcement schedual which the correct response is reinforced after a fixed length of time since the last reinforcment
Term
variable-interval schedual
Definition
a reinforcement schedule in which the correct response is reinforced after a fixed length of time since the last reinforcment
Term
fixed - ratio schedule
Definition
a reinforcment in which the correct response reinforced after a fixed number of responses.
Term
Variable ratio schedule
Definition
a variny number ofcorrect responses must occur before reinforcement is presented
Term
extinction
Definition
a descrease in the strength or frequency or stoping of a learned response because of failuer to continue continue pairing the US and CS or withholding of reinforcment
