Final answer:
ABAB and multiple-baseline experimental designs are both commonly used in the field of psychology to study behavior change.
Step-by-step explanation:
ABAB and multiple-baseline experimental designs are both commonly used in the field of psychology to study behavior change.
Both designs involve the implementation of an intervention or treatment to observe its effect on participants. In an ABAB design, the treatment is systematically applied and withdrawn in a repeated pattern. This allows researchers to determine if changes in the behavior occur when the treatment is implemented and are reversed when it is withdrawn. In a multiple-baseline design, the treatment is applied to different participants or different behaviors at different times. This allows researchers to establish a causal relationship between the treatment and the observed behavior change.
