Purpose
The purpose of this study was to evaluate behavioral sensitivity to differences in the amount and delay of tasks. The study also included an analysis of factors that might influence self-control after the subjects failed to demonstrate self-control. P 228.
Subjects/Setting
Participants are two 4 year old males, John and Archie. Both are diagnosed with autism and show signs of aggression and disruption. Both subjects communicated vocally using complete sentences and followed three-step instructions. Problem behavior was maintained by escape from demands. John’s sessions took place in an unused room at his school and Archie’s in a therapy room at a university-based early intervention program. Both rooms contained tables, chairs, and materials required for the sessions. P 228.
Dependent variable and measure
The first dependent variable of this study was magnitude, or amount of task. The second dependent variable of this study was delay, and the final dependent variable of this study was self-control.
Independent variable
During the magnitude analysis, each subject had to choose between different amounts of the task, number of puzzle pieces for John and number of letter sounds identified for Archie. During the delay analysis portion of the study, participants were instructed to choose a task requiring completion immediately versus one that had to be completed after a 60 s delay. For the self-control portion of the analysis participants were instructed to choose between a small immediate task and a medium (Archie) or large (John) delayed task.
Participants were asked to choose between two tasks that differed only with the amount of
