Quasi-Experimental Design  the IV is naturally manipulated (not by you)  the experimenter doesn’t have control of the IV  there’s non-random assignment  this creates the possibility for confounds  there are three types: nonequivalent control group design, natural experiments, and time series design  in a nonequivalent control group design, the manipulation is a program of some kind o the researcher has control over the active manipulated group, but not the control group o the non-random assignment is basically what makes this a quasi-experimental design o e.g. a school psychologist that is testing the effect of a drug intervention program on drug use might use their school as the manipulated one that goes through the program and another school as the control school o the control group might be the same on some key demographics, but you can never really be sure this control group is the same on all dimensions  is possible these differences between groups can be confounds o pre/post design: looking at drug use before and after the intervention (just looking at the manipulated group; there’s no control group) o one time study: measuring both groups after the program  you’re not taking into account what the schools were like before the program o if you have both groups and do pre/post test for each, you’re controlling for all these factors  natural experiments are the results of events like terrorist attacks, hurricanes, etc… o these are naturally occurring manipulations o typically compare people before and after significant events o someone looked into the effect of bomb attacks on PTSD and anxiety  the different groups included people who didn’t have to take shelter, people who had like a minute to take shelter, and people who had like fifteen seconds  there’s no real control group here  this is not correlational because the bombing occurred  correlation studies has no “event” that it follows o Galea and Kessler studied the psychological effects of Katrina on pre-Katrina residents  five months after Katrina, 50% had anxiety-mood disorder and 30% had PTSD  a year later, these percentages had gotten worse  even though they didn’t have pre-Katrina scores, they could find the effect of Katrina  time series designs are not specific to quasi-experimental designs, but they are commonly used o there are multiple pre-post test measures o these studies look for trends overtime o Interrupted Time Series with Reversal: pretests, start the program, stop the program, posttests o this is a quasi-experimental design because there is no control group o challenges: you can sensitize people to the measures if you do it this often o there are some technical concerns about removing an intervention if it was doing good for the participants Single Case Research  there are several criticisms of group designs: o if you show that a certain manipulation has an effect, you’re showing that the difference between two means is significant o the results don’t generalize to everyone, but to group behavior o group designs don’t study the variability of behavior in an individual over time o if you can’t do a manipulation of an individual, then it must not be important  researchers are often interested in predicting individual behavior  behaviorism is really built on this approach  Piaget developed his theory of cognitive development by watching his children  single case research studies one individual, introducing and removing the independent variable over time  Video: o Levels of IV: 8 hours sleep, 6 30 min naps a day, 10 hour sleep bonus, 6 30 min naps a day o DVs: self-report ratings, performance tests, type of sleep (brainwaves)  Types of Single Case Research o ABA: similar to a quasi-experimental design but with one person (introduce the IV and then remove it while taking measurements) o ABAB: replicate the study within one person o AB1AB2: two different levels of IV  Advantages: o able to show effect of IV in each person examined o can replicate findings within the study of one individual  Disadvantages: o there’s a question of generalization o you can’t examine moderations o involves the introspection of patterns rather than statistical tests
