Figures and tables from research methods for the behavioral sciences. F. j. , foranzo, l. b. (2019) research methods for the behavioral sciences. Describe the general characteristics of a within-subjects experimental design a. Identify these designs when they appear in a research report. Describe how time-related factors such as history, maturation, instrumentation, statistical regression, and order of effects can threaten internal validity of some within-subjects experiments. For a within-subjects experiment, explain how the time delay b/w treatments can influence time- related threats to internal validity and why it might be better to switch to a between-subjects design. Define counterbalancing and explain how it"s used to minimize or eliminate threats to internal validity from time-related factors. Describe limitations of counter-balancing and explain why partial counter-balancing is sometimes used. Explain the general advantages and disadvantages of within-subjects designs compared to between- subjects designs a. Be able to decide which design is better under specific circumstances.
