Five types of stimulus classes Formal, temporal, functional, feature, and arbitrary.
An involuntary behavior that is part of an organism's
Respondent behavior genetic endowment, elicited without any prior learning,
when an eliciting stimulus (US) produces a behavior
(UR/REFLEX).
What occurs when an unconditioned stimulus (US) is
Respondent conditioning paired with a previously neutral stimulus (NS), causing
the neutral stimulus to become a conditioned stimulus
(CS)
without the presence of the unconditioned stimulus (US).
Phylogeny The branch of biology dealing with genetically-inherited
behavior.
When an unconditioned stimulus is presented repeatedly
Habituation
over a short period of time, weakening the strength or
intensity of a respondent behavior (reflex).
A voluntary and learned behavior determined and
Operant behavior
maintained by its history of consequences and defined
by its function (not its topography).
A process that involves an occasional for a behavior
Operant conditioning (Sd), the behavior itself, and the consequence that
follows; a process that determines the future of that
behavior's
occurrence or nonoccurrence.
The branch of biology dealing with learner behaviors
Ontogeny
resulting from interaction with one's environment.

Unconditioned stimulus (US) A stimulus that elicits an automatic response without any prior
learning.
A formally neutral stimulus that had been paired with an
Conditioned stimulus (CS)
unconditioned stimulus and, as a result, can elicit a
relflexive behavior.
Neutral Stimulus (NS) A stimulus that does not elicit a respondent behavior.
An unlearned, automatic response (reflex) that is
Unconditioned response (UR)
elicited by an unconditioned stimulus.
An unlearned, automatic response that is elicited by a
Conditioned response (CR) previously neutral stimulus which has been paired with
an unconditioned stimulus that typically elicits the
response.
Known as the ABCs of behavior, and involves an
occasion for a behavior (A/Sd), the behavior itself (B),
Three-term contingency
and the consequence (C) that follows that behavior.
These components (the antecedent, behavior, and
consequence) make up the core unit of the analysis of
operant behavior.
Three principles of behavior Punishment, extinction, and reinforcement
A stimulus change that follows a behavior, leading to
Reinforcement
that behavior occurring more often or strengthening its
duration, latency, magnitude, or topography in the
future.
A behavior that is followed immediately by the presentation of a
Positive Reinforcement stimulus that
increases the frequency of that and similar behaviors
under similar conditions in the future.
Five types of positive Edible, activity, tangible, social, sensory
reinforcers
A behavior is followed immediately immediately by the
Negative reinforcement reduction or removal of a stimulus that increases the
future frequency of that and similar behaviors under
similar conditions.
Escape contingency The termination of an ongoing aversive stimulus.
When the contingency for behavior is that it prevents
and/or delays the onset of an aversive stimulus. The
Free-operant avoidance
avoidant response occurs without the presence of a

signal/Sd and can occur at any time during an
interval, prior to the scheduled onset of the aversive
stimulus.
A signaled (Sd) contingency for a behavior that
Discriminated avoidance
indicates that engaging in the behavior will prevent
and/or delays the onset of an aversive stimulus.
Avoidance contingency A behavior prevents the onset of an aversive stimulus.
A stimulus change that follows a behavior, resulting in
Punishment
that behavior occurring less often or not at all in the
future.
A process that occurs when the addition of an aversive
Positive Punishment stimulus following a behavior results in a decrease in
the frequency of that, or similar behaviors, under
similiar conditions.
A response is followed immediately by the removal of
Negative Punishment stimulus (or a decrease in the intensity of a stimulus)
and results in a decrease in the future frequency of
similar responses under similar conditions.
A behavior occurs less often (or not at all) in the
Discriminative effects of
Punishment presence of certain conditions (SdP) in which that
behavior has resulted in punishment contingencies in
the past.
The phenomenon whereby behavior is modified by
Automaticity of
reinforcement/punishment consequences, even if a person is unaware of the
contingency.
Reinforcement that occurs without the social mediation
Automatic Reinforcement
of others and is mediated by the self or environmental
(internal or external) variables.

Punishment that occurs without the social mediation of
Automatic Punishment
others and is mediated by the self or environmental
(internal or external) variables.
An individual's access to reinforcement/punishment that
Socially-mediated contingency
is mediated or controlled by another person.
A stimulus change that can increase the future
Unconditioned reinforce3r
(UCR) frequency of behavior without any learning history or
prior pairing with any other form of reinforcement.
A previously neutral stimulus that acquires the ability to function
Conditioned Reinforcer (CR) as a reinforcer
through a stimulus-stimulus pairing with one or more
unconditioned or conditioned reinforcers.
A type of conditioned reinforcer that has been paired
Generalized conditioned
reinforcer (GCSR) with many unconditioned and conditioned
reinforcers.
A stimulus change that decreases the frequency of any
Unconditioned Punisher (UCP)
behavior immediately preceding it, regardless of the
organism's learning history with that stimulus.
A previously neutral stimulus that now functions as a
Conditioned Punisher
punisher because of prior pairing with one or more
other punishing stimuli.
A type of conditioned punisher that has been paired
Generalized conditioned
punishe4r (GCSP) with many unconditioned and conditioned punishers.
Th basic schedule of reinforcement in which a fixed
Fixed ratio schedule (FR)
number of correct responses must be emitted for
reinforcement to be delivered.
The basic schedule of intermittent reinforcement in
Variable ratio schedule (VR)
which a variable number of correct responses must be
emitted for reinforcement to be delivered.
The basic schedule of intermittent reinforcement in
Fixed interval schedule (FI)
which a fixed amount of time must elapse before a
single correct response produces reinforcement.
The basic schedule of intermittent reinforcement in
Variable interval schedule (VI)
which a variable amount of time must elapse before a
single correct response produces reinforcement.
