Term
Automatic reinforcement
Definition
Reinforcement that occurs independent of the social mediation of others (scratching an insect bite relieves the itch)
Term
Automaticity 
Definition
Behavior is modified by its consequences irrespective of the person's awareness
Term
Aversive Stimuli
Definition
Unpleasant stimulus; a stimulus change that functions to evoke a behavior that has terminated it in the past; as a punished when presented following behavior and as a reinforcer when withdrawn following behavior
Term
Behavior
Definition
The portion of an organism's interaction with environment that is characterized by detectable displacement in space through time of some part of the organism and of the environment
Term
Conditioned Reinforcer
Definition
A stimulus change that functions as a reinforcer because of prior pairing with one or more other reinforcers
Term
Conditioned Stimulus
Definition
A formerly neutral stimulus change that elicits respondent behavior only after it has been pair with an unconditioned stimulus or another conditioned stimulus
Term
Contingency
Definition
Dependent and/or temporal relations between operant behavior and its controlling variables
Term
Deprivation
Definition
Amount of time that has passed since an organism has last consumed or contacted a particular reinforcer
Term
Discriminated operant
Definition
An operant that occurs more frequently under some antecedent conditions than under others
Term
Discriminative Stimulus
Definition
An antecedent stimulus that signals that a particular behavior will be reinforced. 
Term
Extinction
Definition
Discontinuing of reinforcement of a previously reinforced behavior
Term
Habituation 
Definition
A decrease in responsiveness to repeated sensations of stimuli
Term
Negative punishment/Type II Punishment 
Definition
A response behavior is followed immediately by the removal of stimulus (or a decrease in the intensity of the stimulus), that decreases future frequency of similar responses under similar conditions
Term
Negative Reinforcer
Definition
a stimulus whose termination (or reduction in intensity) functions as reinforcement
Term
Ontogeny
Definition
The history of the development of an organism during its lifetime
Term
Phylogeny
Definition
The history of the natural evolution of a species
Term
Positive Punishment/Type I Punishment
Definition
A behavior is followed immediately by the presentation of a stimulus that decreases future frequency of behavior
Term
Positive reinforcement
Definition
Occurs when a behavior is followed immediately by the presentation of a stimulus that increases future frequency of the behavior in similar conditions
Term
Punisher
Definition
A stimulus change that decreases the future frequency of behavior that immediately precedes it
Term
Reflex
Definition
A S-R relation consisting of an antecedent stimulus and the respondent behavior it elicits (bright light = pupil contraction)
Term
Repertoire 
Definition
All the behaviors a person can do/a set of behaviors relevant to a particular setting or task
Term
Respondent Behavior
Definition
The response component of a reflex; behavior that is elicited by antecedent stimuli
Term
Respondent Conditioning (Pavlov)
Definition
A stimulus-stimulus pairing procedure where a neutral stimulus is presented with an unconditioned stimulus until the neutral stimulus becomes a conditioned stimulus that elicits a conditioned response
Term
Response
Definition
A single instance or occurrence of a specific behavior of a specific class or type of behavior
Term
Satiation
Definition

Decrease in frequency of operant behavior presumed to be the result of continued contact with of consumption of a reinforcer that has followed that behavior; also reduced the effectiveness of a reinforcer -- when a reinforcer loses its effect due to overuse.

 

Term
Stimulus
Definition
An energy change that affects an organism through its receptor cells
Term
Stimulus Class
Definition
Group of stimuli that share specified common elements along formal (size, color), temporal (antecedent or consequent), and/or functional dimensions (discriminative stimulus).
Term
Stimulus Control
Definition
The frequency, latency, duration or amplitude of a behavior is altered by the presence or absence of an antecedent stimulus
Term
Unconditioned Reinforcement
Definition
A stimulus change that increases the frequency of a behavior that immediately precedes it irrespective of the organism's learning history with the stimulus
