PSYB01H3 Chapter Notes - Chapter 11: Confounding, Regression Analysis, Internal Validity
Document Summary
Chapter 11- single case, quasi-experimental, and developmental research. There are 3 types of special research situations: single case experimental design- form of experiment with only one participant. Was derived to see if an experimental manipulation had effect on single research participant. The subject"s behaviour is measured over time during baseline control period. Then manipulation put in during treatment periods and subject observed again for changes. Only controversy is that the reason for the change could easily be something else than the manipulation hard to tell with one subject: reversal design- form of experiment where the reversibility of the manipulation is tested. This is done by observing the baseline (a) , then the treatment period (b), then observing the second baseline again after the manipulation is withdrawn again, aka withdrawal design. Aba design : a(baseline period) b(treatment period) a (baseline period)
