The purpose of the study “Using LED Lights as Prompts to Teach Receptive Identification to Preschool Children with Autism” is to implement a different prompting procedure than traditional least-to-most prompting procedures in teaching. One prompting procedure commonly used in discrete trial training classrooms involves least-to-most prompting in the form of gestural and physical prompts to guide children to make correct responses during teaching procedures. To specifically teach receptive identification skills, an apparatus with LED lights will be used as a prompting device to vary light intensities on stimuli that the child will choose from. This alternate method of prompting may enable children to acquire the skill to discriminate between stimuli in less time and with more accuracy than the traditional prompting procedure. The LED lights will spotlight the stimuli presented and fade in stages, ranging from all stimuli illuminated to one stimulus illuminated, depending on the number of prompts needed to reduce attention paid to extraneous elements in the environment. A multiple baseline design will be implemented with a preschool child with autism to see the effects of using this LED lighting as a prompt to teach the receptive identification skill. In each baseline phase, the task will be presented to the child; however no prompting will occur and only correct responses will result in reinforcement. Baseline data will be assessed against the intervention data to observe any changes in incorrect or correct responses. Data will be analyzed by reviewing videotapes of the sessions and recording the number of correct and incorrect responses made by the child, along with the specific object stated by the tutor. With the LED apparatus being used to prompt the child, this data will track the child’s progress in learning to identify target objects in the receptive identification procedure.
