EXAM 55 QUESTIONS AND CORRECT
ANSWERS (VERIFIED ANSWERS) |ALREADY
GRADED A+
Event recording - CORRECT ANSWER how often behavior
occurs; use counters; each instance must have beginning and
ending; take into account rate and duration
time sampling - CORRECT ANSWER dividing observation
period into time intervals and then recording the presence or
absence of behavior within or at the end of each interval
whole interval recording - CORRECT ANSWER measure
continuous behavior; 5-15 second intervals; record if behavior
occurred throughout WHOLE interval; reported as percentage;
underestimates; useful for behavior you want to INCREASE
Partial interval recording - CORRECT ANSWER record if
behavior occurred at any time during the interval; allows recording
of multiple behaviors or participants; multiple occurrences scored
as 1; report as percentage; often overestimates; useful for
behavior you want to DECREASE
Momentary time sampling (MTS) - CORRECT ANSWER at the
end of the interval, record if behavior is occurring at the moment;
does not require undivided attention; can miss a lot of behavior;
best for continuous;
Goal of study - CORRECT ANSWER to show functional
relationship between the target behavior and the intervention
Withdrawal (Reversal) design - CORRECT ANSWER treatment
is withdrawn one or more phases of the study; one or more
baseline and intervention phases; demonstrate effects of
treatment (IV) on the target behavior (DV); ABA or ABAB;
increased internal validity
A-B Design - CORRECT ANSWER quasi experimental design;
pre-experimental; most basic and weakest of all designs;
inadequate experimental control; functional relationship between
IV and DV cannot be demonstrated; can't rule out extraneous
factors
Replication - CORRECT ANSWER repeating a previously
observed change with further manipulation of the IV;
demonstrates functional relations; increases likelihood that
change was function of IV
What is the most powerful within-subject design for demonstrating
a functional relation between environmental manipulation and a
behavior? - CORRECT ANSWER ABAB Reversal
Strengths of ABAB reversal-replication design - CORRECT
ANSWER turn behavior on and off; demonstrates functional
relation; high internal validity; involves prediction, verification,
replication;
BAB Reversal Design - CORRECT ANSWER no assessment or
pre-intervention levels; may be appropriate with dangerous
behaviors; when treatment is already in place; limited amount of
time to demonstrate effect
Multiple Treatment Reversal Designs - CORRECT ANSWER
compare effects of two or more experimental conditions with each
other or baseline; ABABC, ABCBCBC
