NSC 2306 practical considerations, quasi experimental research, and nonequivalent group designs, Exam Review. Rated A+ subject pool - -An established group of people who have agreed to be contacted about participating in research studies. experimenter expectancy effect - -When the experimenter's expectations about how participants "should" behave in the experiment affect how the participants behave. manipulation check - -Verifying the experimental manipulation worked by using a different measure of the construct the researcher is trying to manipulate. pilot test - -Is a small-scale study conducted to make sure that a new procedure works as planned. ways to recruit participants - --volunteer subject -subject pool quasi-experimental research - -Studies in which we control many variables, but missing keycharacteristics of true experiments◦ Typically cannot randomly assign participants to the experimentalor control groups◦ Groups are defined in terms of a participant variable◦ Example◦ Compare well-being among women with and without breast cancer one group-posttest only design - -A treatment is implemented (or an independent variable is manipulated) and then a dependent variable is measured once after the treatment is implemented. A major limitation to this design is the lack of a control or comparison group.
