In science in general and in the context of single-case experimental designs, replication of the effects of the intervention within and/or across participants or experiments is crucial for establishing causality and for assessing the generality of the intervention effect. Specific developments and proposals for assessing whether an effect has been…

We reviewed parametric analyses of treatment integrity levels published in 10 behavior analytic journals through 2017. A total of 19 experiments (13 articles) met criteria for review. The objectives were to: (1) determine the number of experiments in which levels of treatment integrity were systematically manipulated; (2) identify the types of…

The effects of 2 forms of response interruption and redirection (RIRD)--motor RIRD and vocal RIRD--were examined with 4 boys with autism to evaluate further the effects of this intervention and its potential underlying mechanisms. In Experiment 1, the effects of motor RIRD and vocal RIRD on vocal stereotypy and appropriate vocalizations were…

This commentary on EC 608 301 points out that devotion to the natural science canon of experimental proof in the area of generality testing requires proof procedures that are difficult, expensive, or impossible, but adopting a different canon of proof will not produce the desired certainty about the accuracy of the answer.

This paper reports two studies that examined changes in the participants' level of moral reasoning after exposure to the Kohlberg cognitive-developmental intervention model (1975). This approach focuses on universal moral principles which are manifested in a series of developmental stages. Knowledge of these stages provides one with an outline for…
