BCBA EXAM 2026 UPDATE QUESTIONS AND
CORRECT VERIFIED ANSWERS ALREADY
GRADED A+ (BRAND NEW VISION)
concept formation - ANS-a complex example of stimulus control that requires both stimulus
generalization within a class of stimuli and discrimination between classes of stimuli
antecedent stimulus class - ANS-a set of stimuli that share a common relationship; all stimuli
in this class evoke the same operant response class or elicit the same respondent behavior
arbitrary stimulus class - ANS-a set of stimuli that evoke the same response, but do not share a
common stimulus feature
feature stimulus class - ANS-a set of stimuli that share common physical forms or common
relative relations
stimulus equivalence - ANS-the emergence of accurate responding to untrained and
nonreinforced stimulus-stimulus relations following the reinforcement of responses to some
stimulus-stimulus relations; requires reflexivity, symmetry, and transitivity
reflexivity - ANS-occurs when in the absence of training and reinforcement a response will
select a stimulus that is matched to itself
symmetry - ANS-occurs with the reversibility of the sample stimulus and comparison stimulus
transitivity - ANS-a derived (e.g. untrained) stimulus-stimulus relation that emerges as a
product of training two other stimulus-stimulus relations
,masking - ANS-when one stimulus has acquired stimulus control over behavior, but a
competing stimulus can block the evocative function of that stimulus
overshadowing - ANS-the presence of one stimulus condition interferes with the acquisition of
stimulus control by another stimulus
most-to-least prompts - ANS-used to transfer stimulus control from response prompts to the
natural stimulus; physically guides participant through entire performance sequence,
gradually reducing the amount of physical assistance provided
least-to-most prompts - ANS-used when transferring stimulus control; participant given
opportunity to perform the response with the least amount of assistance on each trial;
greater degrees of assistance with each successive trial without a correct response
stimulus fading - ANS-highlighting a physical dimension of a stimulus to increase the likelihood
of a correct response and then gradually fading the highlighted dimension
imitation - ANS-(a) any physical movement may function as a model, (b) the behavior must
immediately follow the presentation of the model, (c) the model and the behavior must have
formal similarity, (d) the model must be the controlling variable for the behavior
planned models - ANS-prearranged antecedent stimuli that help learners acquire new skills or
refine the topography of certain elements of existing skills
unplanned models - ANS-all antecedent stimuli with the capacity to evoke imitation
shaping - ANS-the process of systematically and differentially reinforcing successive
approximations to a terminal behavior
,differential reinforcement - ANS-a procedure in which reinforcement is provided for responses
that share a predetermined dimension or quality, and in which reinforcement is withheld for
responses that do not demonstrate that quality
response differentiation - ANS-when differential reinforcement is applied consistently within a
response class and its dual effects result in a new response class composed primarily of
responses sharing the characteristics of the previously reinforced subclass
successive approximations - ANS-a succession of new response classes, each one closer in form
to the terminal behavior than the response class it replaces
clicker-based training - ANS-a science-based system for shaping behavior using positive
reinforcement
behavior chain - ANS-a specific sequence of discrete responses, each associated with a
particular stimulus condition that produces a terminal outcome
behavior chain with a limited hold - ANS-a sequence of behaviors that must be performed
correctly and within a specified time to produce reinforcement
chaining - ANS-various methods for linking specific sequences of stimuli and responses to form
new performances
forward chaining - ANS-chaining which links behaviors beginning with the first behavior in the
sequence and in which behaviors identified in the task analysis are taught in their naturally
occurring order
, backward chaining - ANS-chaining which links behaviors beginning with the last behavior in the
sequence; the behaviors identified in the task analysis are initially completed by the trainer,
except for the final behavior
task analysis - ANS-breaking a complex skill into smaller, teachable units, resulting in a series of
sequentially ordered steps
total-task chaining - ANS-a variation of forward chaining in which the learner receives training
on each step in the task analysis during ever session
backward chaining with leap aheads - ANS-almost identical to backward chaining, except not
every step in the task analysis is trained, some steps are probed; decreases total training time
behavior chain interruption strategy - ANS-strategy that relies on the participant's skill to
perform the critical elements of a chain independently, but the chain is interrupted at a
predetermined step so that another behavior can be emitted
extinction - ANS-a procedure that occurs when reinforcement of a previously reinforced
behavior is discontinued; as a result the frequency of that behavior decreases in the future
escape extinction - ANS-when behaviors maintained by negative reinforcement do not produce
removal of the aversive stimulus, meaning that the person cannot escape from the aversive
situation
sensory extinction - ANS-when sensory consequences that maintain behavior are masked
resistance to extinction - ANS-continued responding during extinction procedure
