This last of the four case studies is adapted from a working paper completed by Rhea Paul. It was one of the first attempts to use the NPA procedure as a research tool. This extended case study is more lengthy than the previous three case studies and organized differently. It is included here because it nicely illustrates the discovery procedures that clinical researchers must undertake to more fully understand associations between speech and language.
