Ch. 13 Flashcards
What is an interrupted time-series design?
a quasi-experiment in which participants are measured repeatedly on a dependent variable before, during and after the “interruption” caused by some event
What is a multiple-baseline design?
a small-N design in which researchers stagger their introduction of an intervention across a variety of contexts, times or situations
What is a nonequivalent control group posttest-only design?
a quasi-experiment that has at least one treatment group and one comparison group, but participants have not been randomly assigned to the two groups
What is the nonequivalent control group pretest/posttest design?
a quasi-experiment that has at least one treatment group and one comparison group, in which participants have not been randomly assigned to the two groups, and in which at least one pretest and one posttest are administered
What is a nonequivalent control group interrupted time-series design?
A quasi-experiment with two or more groups in which participants have not been randomly assigned to groups; participants are measured repeatedly on a dependent variable before, during and after the interruption caused by some event, and the presence or timing of the interrupting event differs among the groups
What is a quasi-experiment?
a study similar to an experiment except that the researchers do not have full experimental control
What is a quasi-independent variable?
A variable that resembles an independent variable, but the researcher does not have true control over (ex: can’t control timing)
What is a wait-list design?
an experimental design for studying therapeutic treatment in which researchers randomly assign some participants to receive the therapy under investigation immediately, and others to receive it after a time delay
What is a reversal design?
a small-N design in which a researcher observes a problem behaviour both before and during treatment, and then discontinues the treatment for a while to see if the problem behaviour returns
What is a small-N design?
a study in which researchers gather information from just a few cases
What is a stable-baseline design?
a small-n design in which a researcher observes behavior for an extended baseline period before beginning a treatment or other intervention, and continues observing behaviour after the intervention
What is a single-N design?
a study in which a researcher gather information from only one animal or one person
