Term
learning
Definition
a process by which behavior or knowledge changes as a result of experience
Term
classical conditioning
Definition
learning that occurs when a neutral stimulus elicits a response that was originally caused by another stimulus
Term

unconditioned stimulus

US

Definition
a stimulus that elicits a reflexive response without learning
Term

unconditioned response

UR

Definition
a reflexive, unlearned reaction to an unconditioned stimulus
Term

conditioned stimulus

CS

Definition
a once neutral stimulus that elicits a conditional response because it has a history of being paired with an unconditioned stimulus
Term

conditioned response

CR

Definition
the learned response that occurs to the conditioned stimulus
Term
acquisation
Definition
the initial phase of learning in which a response is established
Term
extinction
Definition
the loss or weakening of a conditioned response when a conditioned stimulus and inconditioned stimulus no longer occur together
Term
spontaneous recovery
Definition
the reoccurance of a previously extinguished condition response, typically after some time has passed since extinction
Term
discrimination
Definition
occurs when an organism learns to respond to one original stimulus but not to a new stimuli that may be similar to the original stimulus
Term
conditioned emotional responses
Definition
consist of emotional and physiological responses that develop to a specific object or stimulation
Term
preparedness
Definition
refers to the biological predisposition to rapidly learn a response to a particular class of stimuli
Term
conditioned taste adversion
Definition
the acquired dislike or disgust of a food or drink because it was paired with illness
Term
operant conditioning
Definition
a type of learning in which behavior is influenced by consequenses
Term
reinforcement
Definition
a process in which an event or reward that follows a response increases the likelihood of that response occuring again
Term
reinforcer
Definition
a stimulus that is conringent upon a response, and that increases the probability of that response occuring again
Term
punishment
Definition
a process that decreases the future probability of a response
Term
punisher
Definition
a stimulus that is contingent upon a response, and that results in a decrease in behavior
Term
primary reinforcers
Definition
consist of reinforcing stimulu that satisfy basic motivational needs
Term
secondary reinforcers
Definition
consist of reinforcing stimuli that acquire their value through learning
Term
positive reinforcement
Definition
the strengthening of behavior after potential reinforcers such as praise, money, or nourishment follow that behavior
Term
negative reinforcement
Definition
involves the strengthening of a behavior because it removes or diminishes a stimulus
Term
avoidance learning
Definition
a specific type of negative reinforcement that removes the possibility that a stimulus will occur
Term
escape learning
Definition
occurs if a response removes a stimulus that is already present
Term
positive punishment
Definition
a process in which a behavior decreases because it adds or increases a particular stimulus
Term
negative punishment
Definition
occurs when a behavior decreases because it removes or diminishes a particular stimulus
Term
discriminative stimulus
Definition
a cue or event that indicates that a response, if made, will be reinforced
Term
shaping
Definition
a procedure in which a specific operant response is created by reinforcing successive approximation of that response
Term
schedules of reinforcement
Definition
rules that determine when reinforcement is available
Term
continuous reinforcement
Definition
every response made results in reinforcement
Term
partial (intermittent) reinforcement
Definition
only a certain number of responses are rewarded, or a certain amount of time must pass before reinforcement is made available
Term
fixed-ratio schedule
Definition
reinforcement in delivered after a specific number of responses have been completed
Term
variable-ratio schedule
Definition
the number of responses requred to recieve reinforcement varies according to an average
Term
fixed-interval schedule
Definition
reinforces the first response occurring after a set amount of time passes
Term
variable-interval schedule
Definition
the first response is reinforced following a variable amount of time
Term
partial reinforcement effect
Definition
a phenomenon in which organisms that have been conditioned under partial reinforcement resist extinction longer than those conditioned under continuous reinforcement
Term
latent learning
Definition
learning that is not immediately expressed by a response until the organism is reinforced for doing so
Term
observational learning
Definition
involves changes in behavior and knowledge that result from watching others
Term
imitation
Definition
recreating a motor behavior or expression, often to accomplish a specific goal
