Document Summary
Graph visual representation of the occurrence of a behavior over time. Determines whether treatment (iv) influenced target behavior (dv) to rule out possibility of confounding variables affecting dv. Functional relationship behaviour changes as a function of the procedure. Established if: dv changes when iv is manipulated, while all other variables are held constant, process is repeated one or more times and dv changes each time. Is rarely used in behavior modification research (most often is used in applied, nonresearch situations in which people are more interested in demonstrating that behavior change has occurred than in proving that the behavior modification procedure caused the change) A-b-a-b reversal design baseline and treatment are implemented twice. There is a baseline and treatment phase for 2 or more settings in which the same behavior of the subject is measured. Alternating-treatment design (multielement design) baseline and treatment(s) are conducted in rapid succession and compared with each other.
