The following topics are discussed: the status of behavior analysis as a scientific discipline and the related consequences to the characterization of research methods in behavior analysis. The array of research methods is classified according to distinct criteria, with an emphasis on experimental research. Underlying principles and main features of single case designs are presented.Finally, some of the current conceptual-methodological issues in behavior analysis are briefly discussed, such as: behavioral reversibility, behavioral variability, trial and free operant procedures, molecular and molar analysis, statistics and quantification applied to single case procedures and experimental research with human participants.
