Sy, Jolene R.; Vollmer, Timothy R. – Journal of Applied Behavior Analysis, 2012
We evaluated the discrimination acquisition of individuals with developmental disabilities under immediate and delayed reinforcement. In Experiment 1, discrimination between two alternatives was examined when reinforcement was immediate or delayed by 20 s, 30 s, or 40 s. In Experiment 2, discrimination between 2 alternatives was compared across an…

Ahrens, Erin N.; Lerman, Dorothea C.; Kodak, Tiffany; Worsdell, April S.; Keegan, Courtney – Journal of Applied Behavior Analysis, 2011
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…

Lionello-DeNolf, Karen; Dube, William V. – Journal of the Experimental Analysis of Behavior, 2011
Training context can influence resistance to disruption under differing reinforcement schedules. With nonhumans, when relatively lean and rich reinforcement schedules are experienced in the context of a multiple schedule, greater resistance is found in the rich than the lean component, as described by behavioral momentum theory. By contrast, when…

Lefebre, Elizabeth; Fabrizio, Michael; Merbitz, Charles – Journal of Precision Teaching and Celeration, 2008
Although behavior analysis relies primarily on visual inspection for interpreting data, previous research shows that the method of display can influence the judgments. In the current study, 26 Board-Certified Behavior Analysts reviewed two data sets displayed on each of three methods--equal-interval graphs, tables, and Standard Celeration…

Pavlik, Philip I.; Anderson, John R. – Journal of Experimental Psychology: Applied, 2008
By balancing the spacing effect against the effects of recency and frequency, this paper explains how practice may be scheduled to maximize learning and retention. In an experiment, an optimized condition using an algorithm determined with this method was compared with other conditions. The optimized condition showed significant benefits with…

McDermott, Josh; Hauser, Marc D. – Cognition, 2007
Human adults generally find fast tempos more arousing than slow tempos, with tempo frequently manipulated in music to alter tension and emotion. We used a previously published method [McDermott, J., & Hauser, M. (2004). Are consonant intervals music to their ears? Spontaneous acoustic preferences in a nonhuman primate. Cognition, 94(2), B11-B21]…
