PSYB01H3 Chapter Notes - Chapter 11: Program Evaluation, Quasi, Causal Inference
Document Summary
Chapter 11- single- case, quasi- experimental, and developmental research. Determines whether an experimental manipulation has an effect on a single research p. Subject"s behaviour is measured over time during baseline control period. Manipulation is then introduced during treatment period; and p"s behaviour is still observed. Baseline period treatment period baseline period. Aba design/ withdrawal design (since treatment is withdrawn) Can be improves to an abab or ababab design: helps to see if change in behaviour was due to a different variable, ethical- not right to end the treatment, so it"s best to add the b. Effectiveness of the design is shown when a behaviour changes only after the manipulation is introduced. Change must be observed under multiple circumstances to rule out other causes. Program evaluation- research on programs that are implemented to achieve some positive effect on a group of individuals.
