What is a Mixed Design?
A factorial design that includes at least one within-subjects independent variable and at least one between-subjects independent variable
What do Participants Receive in Mixed Designs:
Each level of the within-subjects independent variable but only one level of the between-subjects independent variable
Single-subject Design (or single-case experimental design):
A special type of within-subjects design using one participant or one group to assess changes within that individual or group
What is an A-B Design?
A single-subject design in which researchers take a baseline measurement (A), then introduce the intervention, and then measure the same variable again (B)
What is an A-B-A Design?
A single-subject design in which researchers establish a baseline (A), introduce the intervention and measure the same variable again (B), then remove the intervention and take another measurement (A)
What is an A-B-A-B Design?
A single-subject design in which researchers establish a baseline (A), introduce the intervention (A), and then reintroduce the intervention (B), measuring the DV each time
What is a Mixed Design?
An experimental design that combines within-subjects and between-subjects methods of data collection
What is the Treatment-as-Usual Group?
A comparison group often used in clinical research in which an already established treatment is administered for comparison to experimental treatment
What is the Waiting-list Control Group?
A control group is often used in clinical research; participants in this group do not receive treatment or intervention until after the completion of the study
What is the Experimenter-Expectancy Bias Effect?
Occurs whan a bias causes a researcher to unconsciously influence the participants of an experiment
What is a Double-Blind Procedure?
Both the participants and the administrators of treatment are unaware of, or blind to, the types of treatment being provided in order to reduce the likelihood that expectancies or knowledge of condition will influence the results
What is the Single-Blind Procedure?
Participants are unaware of, or blind to, the types of treatment they are receiving, but the administrator knows
What is a Mixed-Design ANOVA?
A statistical analysis that tests for differences between two or more categorical IVs, where at least one is a between-subjects, and another is a within-subjects variable
