ACTUAL QUESTIONS AND CORRECTLY
WELL DEFINED ANSWERS LATEST 2024 –
2025 ALREADY GRADED A+
time lagged designs - ANSWERS-include the repetition of basic A-B comparison
across a set of three or more participants, behaviors, or contexts
rapid iterative alternation - ANSWERS-repetition of an A-B comparison with single
session replication and comparisons
clinical replication - ANSWERS-administration of a treatment package containing
two or more distinct treatment procedures by the same investigator or group of
investigators, administered in a specific setting to a series of clients presenting
similar combinations of multiple behavioral and emotional problems, which
usually cluster together
which is the most powerful within-subject design? - ANSWERS-ABAB
in withdrawal designs, when is procedural infidelity most likely to occur? -
ANSWERS-immediately after condition changes
strongest threats to internal validity for withdrawal/reversal designs include all of
the following except - ANSWERS-history
the primary ethical concern associated with withdrawal designs is - ANSWERS-
removing a successful intervention
external validity of an ABAB design can be improved by - ANSWERS-having at least
3 participants
when using "ABC Notation," the B stands for - ANSWERS-intervention 1
which of the following is NOT a limitation of an AB design (intervention is not
withdrawn, lack of control for internal validity, lack of control for external validity,
cannot determine functional relationships) - ANSWERS-intervention is not
withdrawn
,what can researchers do to help avoid attrition in withdrawal designs? -
ANSWERS-disclose and describe the withdrawal condition during the consent
process
the withdrawal design is not particularly sensitive to which threats to internal
validity?
a) history, maturation, data instability
b) procedural infidelity, attrition, maturation
c) carryover effects, hawthorne effect, irreversibility of behaviors
d) testing, procedural infidelity, data instability - ANSWERS-d
history - ANSWERS-refers to events that occur during an experiment, but are not
related to planned procedural changes that may influence the outcome
maturation - ANSWERS-changes in behavior due to passage of time
testing - ANSWERS-threat in any study that requires participants to respond to the
same test repeatedly
facilitative effect - ANSWERS-an improvement in performance over successive
baseline or probe testing or observation sessions
inhibitive effect - ANSWERS-a deterioration in performance over successive
baseline or probe testing or observation sessions
, multiple-treatment interference - ANSWERS-occurs when a study participant's
behavior is influenced by more than one planned "treatments" or interventions
during the course of a study
sequential confounding - ANSWERS-when the order in which experimental
conditions are introduced to participants influences their behavior
carryover effect - ANSWERS-the effect when a procedure used in one
experimental condition influences behavior in an adjacent condition
instability - ANSWERS-the amount of variability in the data over time
cyclical veriability - ANSWERS-a specific type of data instability that refers to a
repeated and predictable pattern in the data series over time
variability - ANSWERS-also referred to as data instability
regression to the mean - ANSWERS-refers to the likelihood that following an
outlying data point, data are likely to revert back to levels closer to the average
value
instrumentation threats - ANSWERS-refers to the concerns of the measurement
system
