strongest threats to internal validity for withdrawal/reversal designs include all of the
following except - CORRECT ANSWER history
the primary ethical concern associated with withdrawal designs is - CORRECT ANSWER
removing a successful intervention
external validity of an ABAB design can be improved by - CORRECT ANSWER having at
least 3 participants
unlike withdrawal designs, reversal designs involve - CORRECT ANSWER a second
intervention phase
which is the most powerful within-subject design? - CORRECT ANSWER ABAB
in withdrawal designs, when is procedural infidelity most likely to occur? - CORRECT
ANSWER immediately after condition changes
when using "ABC Notation," the B stands for - CORRECT ANSWER 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which of the following is NOT a limitation of an AB design (intervention is not withdrawn,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functional relationships) - CORRECT ANSWER intervention is not withdrawn
what can researchers do to help avoid attrition in withdrawal designs? - CORRECT
ANSWER disclose and describe the withdrawal condition during the consent process
the withdrawal design is not particularly sensitive to which threats to internal validity?
, 2024-2025 SPCE 630 FINAL EXAM
a) history, maturation, data instability
b) procedural infidelity, attrition, maturation
c) carryover effects, hawthorne effect, irreversibility of behaviors
d) testing, procedural infidelity, data instability - CORRECT ANSWER d
history - CORRECT ANSWER refers to events that occur during an experiment, but are
not related to planned procedural changes that may influence the outcome
maturation - CORRECT ANSWER changes in behavior due to passage of time
testing - CORRECT ANSWER threat in any study that requires participants to respond to
the same test repeatedly
facilitative effect - CORRECT ANSWER an improvement in performance over successive
baseline or probe testing or observation sessions
inhibitive effect - CORRECT ANSWER a deterioration in performance over successive
baseline or probe testing or observation sessions
multiple-treatment interference - CORRECT ANSWER 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 - CORRECT ANSWER when the order in which experimental
conditions are introduced to participants influences their behavior
