Single-subject research : ウィキペディア英語版 | Single-subject research Single-subject research is a group of research methods that are used extensively in the experimental analysis of behavior and applied behavior analysis with both human and non-human participants. Principal methods in this type of research are: A-B-A-B designs, Multi-element designs, Multiple Baseline designs, Repeated acquisition designs, Brief experimental designs and Combined designs.〔see Craig H. Kennedy, Single Case Designs for Educational Research 2005. ISBN 0-205-34023-7.〕 These methods form the heart of the data collection and analytic code of behavior analysis. Behavior analysis is data driven, inductive, and disinclined to hypothetico-deductive methods.〔Chiese, Mecca. (2004). ''Radical Behaviorism: The Philosophy and the Science''.〕 Statistical methods have been largely ignored. == Experimental questions ==
Experimental questions are decisive in determining the nature of the experimental design to be selected. There are four basic types of experimental questions: demonstration, comparison, parametric, and component.〔Craig H. Kennedy, Single Case Designs for Educational Research 2005. ISBN 0-205-34023-7. pp 65-66〕 A demonstration is "Does A cause or influence B?". A comparison is "Does A1 or A2 cause or influence B more?". A parametric question is "How much of A will cause how much change or influence on B?". A component question is "Which part of A - A1 or A2 or A3... - causes or influences B?" where A is composed of parts which can be separated and tested.〔ibid〕 The A-B-A-B design is useful for demonstration questions.
