EDF 6223 FINAL EXAM QUESTIONS AND
ANSWERS GRADED A+ 2025/2026
Reflexivity - ANS A type of stimuli-to-stimulus relation in which the learner, without any prior
training or reinforcement, selects a stimulus that is the same as the sample.
A=A, B=B, and C=C
Symmetry - ANS A type of stimuli-to-stimulus relation in which the learner, without prior
training or reinforcement, demonstrates the reversibility of the sample stimulus and the
comparison stimulus.
A=B, then B=A, or A=C, then C=A
Transitivity - ANS Describes the stimulus-stimulus relations that emerge as a product of
training two other stimulus-stimulus relations.
If A=B and A=C, then B=C
Stimulus equivalence - ANS Describes a behavior analytic approach to understanding and
establishing symbolic function.
Generativity - ANS The ability to create and understand an infinite number of meaningful
sentences and utterances.

,Relational Frame Theory (RTF) - ANS A theory of derived stimulus relations proposing that
such relations are inherently verbal and that the accumulated experience with relational
exemplars creates generalized repertoires of relating.
derived stimulus relation - ANS The relation between two or more stimuli that is not directly
trained or taught and is not based solely on the physical properties of the stimuli.
Conditional Discrimination - ANS Performance in a match-to-sample procedure in which
discrimination between the comparison stimuli is conditional on, or depends on, the sample
stimulus present on each trial.
Conditional Discrimination 4-term contingency - ANS - sample stimulus (antecedent stimulus)
- correct comparison (antecedent stimulus)
- selection response
- reinforcer
equivalence test - ANS A probe for the emergence of untrained stimulus-stimulus relations
that evaluates both symmetry and transitivity simultaneously.
Mutual Entailment - ANS A relation in one direction between two stimuli (e.g., A to B) entails
a relation in the other direction (e.g., B to A)
(symmetry)
if you are told that A = B, you can derive that B = A. That is, the specified A = B relation mutually
entails the (symmetrical) B = A relation.
Combinatory Entailment - ANS A derived stimulus relation in which two or more stimulus
relations (trained or derived) mutually combine.

, (transitivity)
if A is related to B and A is related to C, then B and C are mutually related in that context.
Class merger - ANS Independent equivalence classes are combined as the result of teaching a
new but interrelated conditional discrimination.
Class expansion - ANS A new member is added to a demonstrated stimulus equivalence class
as the result of teaching a new conditional discrimination.
Equivalence Class - ANS The collection of stimuli that evoke the same behavior.
Arbitrary stimulus class - ANS Stimuli that evoke the same response, but they do NOT share a
common stimulus feature. They do not physically look alike or share a relative relationship.
LIMITED number of stimuli
Developed through stimulus equivalence.
Equivalence Relations - ANS Relations that are reflexive, symmetric, and transitive.
Transformation of stimulus functions (Transformation of Function) - ANS Occur when the
functions of one stimulus alter or transform the functions of another stimulus in accordance
with the derived relation between the two, without additional training.
Generalized Operant - ANS An operant in which the form of the individual responses in the
class vary considerably
Contextual cues - ANS Establish what relations exists between stimuli
