An Examination Of The Differential Outcomes Effect When Teaching Discriminations To Children With Autism And Other Developmental Disabilities, Laura Addison
LSU Doctoral Dissertations
The differential outcomes effect (DOE) refers to the finding that performance in discrimination training improves when different behaviors produce different reinforcers. In the current study, the effects of two DOE procedures on the acquisition of receptive language skills were compared. Participants were four children with autism and/or developmental delay/speech and language impairment. The children were presented with two toy or food items and asked to give the experimenter the item named. The names consisted of three-letter nonsense syllables. Correct responses were followed by one of the following consequences: (a) The opportunity to manipulate or consume the item to which the …

Evaluating Preference For Reinforcers Under Varying Schedule Requirements In Children With Developmental Disabilities, Tiffany Michelle Kodak
LSU Doctoral Dissertations
Previous research has shown that preference for concurrently available reinforcers can be influenced by the reinforcement schedule (DeLeon, Neidert, Anders, & Rodriguez-Catter, 2001; Tustin, 1994). However, limited research has been conducted on specific variables that may influence preference under various schedule requirements. The present study evaluated the influence of task preference, schedule, and quality of reinforcement on choice between either an arbitrary reinforcer or a functional reinforcer. Five participants diagnosed with Autism participated in the study. In the first phase, we evaluated the effects of task preference and schedule of reinforcement on choice between a 30-s break and a high …
