Dr. lowell is using a special type of single-subject design in order to assess changes within a single individual.
In design of experiments, unmarried-subject curriculum or single-case studies layout (SCED) is a research layout most customarily used in implemented fields of psychology, training, and human behavior in which the challenge serves as his/her personal manipulate, instead of the use of some other character/institution.
Researchers use single-problem layout because these designs are sensitive to individual organism variations vs organization designs that are touchy to averages of businesses. The good judgment behind single challenge designs is 1) Prediction, 2) Verification, and 3) Replication.
The baseline statistics predicts behaviour by using maintaining the resultant. Verification refers to demonstrating that the baseline responding would have endured had no intervention been applied. Replication takes place when a formerly found behaviour changed is reproduced.
