McDowell, J. J.; Caron, Marcia L.; Kulubekova, Saule; Berg, John P. – Journal of the Experimental Analysis of Behavior, 2008
Virtual organisms animated by a computational theory of selection by consequences responded on symmetrical and asymmetrical concurrent schedules of reinforcement. The theory instantiated Darwinian principles of selection, reproduction, and mutation such that a population of potential behaviors evolved under the selection pressure exerted by…

Luman, Marjolein; Oosterlaan, Jaap; Sergeant, Joseph A. – Journal of Abnormal Child Psychology, 2008
The present study investigated the impact of reinforcement valence and magnitude on response timing in children with ADHD. Children were required to estimate a 1-s interval, and both the median response time (response tendency) and the intrasubject-variability (response stability) were investigated. In addition, heart rate and skin conductance…

McDowell, J. J. – Journal of the Experimental Analysis of Behavior, 2004
Darwinian selection by consequences was instantiated in a computational model that consisted of a repertoire of behaviors undergoing selection, reproduction, and mutation over many generations. The model in effect created a digital organism that emitted behavior continuously. The behavior of this digital organism was studied in three series of…
