CHAPTER 12 Flashcards
what are Types of quasi-experimental designs
Multiple time design, Non-equivalent control groups, time series
what are Nonequivalent Groups
Involves a control group similar to the
experimental group, but that was not created
by random assignment of participants
what are Time-Series Designs
quasi-experimental design where participants who have
been exposed to a treatment are tested both before and after
the introduction of that treatment, over time
what is a Interrupted Time Series
The researcher takes several pretest
measures and several posttest measures.
no control group
what is Nonequivalent control groups
interrupted time-series
(aka Multiple Time-Series Design
like interrupted time series, but includes comparison group
what are Small-N Designs
Helpful for studying rare/unique issues or people and in clinical settings
what are types of Small-N Designs
Stable-baseline design/Reversal design/ Multiple-baseline design
what is Stable-Baseline Design
A researcher observes behavior for an
extended baseline period before beginning treatment or other intervention
what is Reversal Design (ABAB
Design)
introducing and withdrawing behaviors (introduce method/withdraw/noticed change/introduce
Multiple baseline across settings/situations
Measure our
targeted behavior in different settings and apply treatment in
one setting at a time.
Multiple baseline across behaviors design—introduce treatment
for more than one behavior
introduce treatment
for more than one behavior
Multiple baseline across participants design
introduce
treatment for more than one participant
To examine how a reward influences a desired behavior, a
mother first counts the number of times her son makes his bed
over a two-week period. For the next two weeks, she gives
him a reward every time he makes his bed. Following this
period, she stops giving him a reward and again counts the
number of times he makes his bed. After another 2 weeks,
she re-introduces the reward. This procedure would be an
example of a(n) _____ design?
reversal design
Professor Briscoe finds that when he smiles and makes eye
contact with Jeanne, she becomes more responsive to his
questions. He tries the same behavior on David, Chris, and
B.J. and finds that it also influences their responses to his
questions. What type of small-N design did Professor Briscoe
employ?
multiple-baseline design across subjects
Sarah finds that her son James enjoys lemon
candy. Sarah reinforces James when he displays
courteous behavior at home. She then starts to
reinforce this behavior at school, relatives’ homes,
and church. What type of small-N design did
Sarah employ?
multiple-baseline design across situations
