Single subject controlled experiments in aphasia: The science and the state of the science

Abstract: This paper discusses the use of single subject controlled experimental designs for investigating the effect of treatment for aphasia. A brief historical perspective is presented, followed by discussions of the advantages and disadvantages of single subject and group approaches, the basic requirements of single subject experimental research, and crucial considerations in design selection. In the final sections, results of reviews of published single subject controlled experiments are discussed, with emphasis on… Show more

“…Across the ANCOVAs, more generalization was observed from relatively complex sentence structures (OR and PA) than from relatively simpler sentence structures (OC and UNACC). The pattern of greater instances of generalization from complex to simple structures than from simple to complex structures is consistent with prior treatment research examining the effects of complexity in syntactic (Thompson, 2001(Thompson, , 2006Thompson et al, 1993Thompson et al, , 1997Thompson et al, , 1998Thompson et al, , 2003 and semantic (Kiran, 2007(Kiran, , 2008Kiran, Sandberg, & Sebastian, 2011; therapies. Therefore, results add to the body of work in support of the CATE, which proposes that treatment targeting complex structures enhances generalization to relatively less complex structures.…”

“…ingle-case design, also called single-subject experimental design, is a widely used methodology in the study of interventions for communication disorders (Kearns, 1986;McReynolds & Kearns, 1983;McReynolds & Thompson, 1986;Robey, Schultz, Crawford, & Sinner, 1999;Thompson, 2006). The single-case design involves measuring a behavior before, during, and/or after treatment in an individual or small sample of individuals.…”

“…The single-case design involves measuring a behavior before, during, and/or after treatment in an individual or small sample of individuals. A distinguishing characteristic of single-case design is the collection of multiple repeated measurements of a dependent variable within each subject (Horner & Odom, 2014;Thompson, 2006). Using these repeated measures, the design aims to demonstrate a functional or causal relationship between the application of an intervention and a change in the dependent variable.…”
