Peebles, K. A.; Price, T. J. – Journal of Intellectual Disability Research, 2012
Background: In most individuals, injury results in activation of peripheral nociceptors (pain-sensing neurons of the peripheral nervous system) and amplification of central nervous system (CNS) pain pathways that serve as a disincentive to continue harmful behaviour; however, this may not be the case in some developmental disorders that cause…

Frank-Crawford, Michelle A.; Borrero, John C.; Nguyen, Linda; Leon-Enriquez, Yanerys; Carreau-Webster, Abbey B.; DeLeon, Iser G. – Journal of Applied Behavior Analysis, 2012
The delivery of food contingent on 10 s of consecutive toy engagement resulted in a decrease in engagement and a corresponding increase in other responses that had been previously reinforced with food. Similar effects were not observed when tokens exchangeable for the same food were delivered, suggesting that engagement was disrupted by the…

Falcomata, Terry S.; Roane, Henry S.; Pabico, Robert R. – Research in Autism Spectrum Disorders, 2007
Pica is a potentially life-threatening behavior displayed by many individuals with developmental disabilities. In the present study, stimulus control procedures were examined during the treatment of pica exhibited by a 12-year-old boy with autism. First, the inhibitory effect of a treatment package was tested. Next, neutral stimuli (i.e.,…

van Oorsouw, W. M. W. J.; Israel, M. L.; von Heyn, R. E.; Duker, P. C. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2008
In this study, the side effects of contingent shock (CS) treatment were addressed with a group of nine individuals, who showed severe forms of self-injurious behavior (SIB) and aggressive behavior. Side effects were assigned to one of the following four behavior categories; (a) positive verbal and nonverbal utterances, (b) negative verbal and…

Roane, Henry S.; Falcomata, Terry S.; Fisher, Wayne W. – Journal of Applied Behavior Analysis, 2007
Within the context of behavioral economics, the ratio of response requirements to reinforcer magnitude is called "unit price." In this investigation, we yoked increases in reinforcer magnitude with increases in intervals of differential reinforcement of other behavior (DRO) to thin DRO intervals to a terminal value. (Contains 1 figure.)

Harding, Jay; Wacker, David P.; Berg, Wendy K.; Barretto, Anjali; Ringdahl, Joel – American Journal on Mental Retardation, 2005
We evaluated the influence of child location on the occurrence of self-injurious behavior (SIB) during functional analyses conducted in home settings. An initial functional analysis conducted with 2 children who had developmental disabilities showed undifferentiated patterns of SIB. Analyses of behavior during free play suggested that the child's…

Thomas, Craig A.; Fraiser, Jade – Journal of Early and Intensive Behavior Intervention, 2005
A functional analysis was performed on a five-year-old nonverbal Autistic female with severe self-injurious behaviors. The self-injurious behaviors (hand-to-head, hand-to-jaw, hand-to-face) and loud vocalizations were targeted. Two types of sessions, enriched environment and instructor controlled preferred stimuli, were alternated throughout the…
