Groskreutz, Nicole C.; Groskreutz, Mark P.; Higbee, Thomas S. – Research in Autism Spectrum Disorders, 2011
We assessed the effects of varying the treatment integrity of a prompting procedure on appropriate toy manipulation in two preschool-aged children with autism. Following an assessment to identify toys with high levels of inappropriate toy manipulation, each of three toys was associated with implementation of the prompting procedure at a different…

van Swieten, Lisa M.; van Bergen, Elsje; Williams, Justin H. G.; Wilson, Andrew D.; Plumb, Mandy S.; Kent, Samuel W.; Mon-Williams, Mark A. – Journal of Experimental Psychology: Human Perception and Performance, 2010
Grip selection tasks have been used to test "planning" in both autism and developmental coordination disorder (DCD). We differentiate between "motor" and "executive" planning and present a modified motor planning task. Participants grasped a cylinder in 1 of 2 orientations before turning it clockwise or anticlockwise.…

Ladd, Mara V.; Luiselli, James K.; Baker, Lorianne – Child & Family Behavior Therapy, 2009
Children with autism frequently display self-injurious behavior (SIB), but skin picking--a less severe topography of SIB--has not been the focus of much clinical research. The present study evaluated a home-based intervention that was implemented with a 9-year-old girl who had autism and picked her fingers with resulting tissue damage. The…

Lanovaz, Marc J.; Fletcher, Sarah E.; Rapp, John T. – Behavior Modification, 2009
We used a three-component multiple-schedule with a brief reversal design to evaluate the effects of structurally unmatched and matched stimuli on immediate and subsequent vocal stereotypy that was displayed by three children with autism spectrum disorders. For 2 of the 3 participants, access to matched stimuli, unmatched stimuli, and music…

Rapp, John T.; Vollmer, Timothy R.; St. Peter, Claire; Dozier, Claudia L.; Cotnoir, Nicole M. – Journal of Applied Behavior Analysis, 2004
Three experiments were conducted to evaluate response allocation of stereotypy during free-operant and restricted-operant conditions. Five children with autism or related developmental disabilities participated in at least one and up to three of the experiments. In Experiment 1, the stereotypic response that emerged as most probable during a…

Gutierrez, Anibal, Jr.; Vollmer, Timothy R.; Dozier, Claudia L.; Borrero, John C.; Rapp, John T.; Bourret, Jason C.; Gadaire, Dana – Journal of Applied Behavior Analysis, 2007
Acquisition of verbal behavior is a major goal of interventions for children with developmental disabilities. We evaluated the effectiveness of manipulation of an establishing operation for functional discriminated mands. Four individuals with developmental disabilities participated in a training procedure designed to teach two separate mands for…
