View File

The aim of this research was to apply and to analyze the effects of the Picture Exchange Communication System (PECS) associated with the Video Modeling (VM) to increase the verbal communication skills of three children with a diagnosis of Down syndrome and complex communication needs. This study was conducted in a special school. In order to verify the effects of the PECS associated with the VM a multiple baseline design across subjects was used. However, the baseline occurred in previous sessions to the training of PECS associated with the VM. The communication partner stood in front of the participants, the figure of a desired item was on the table in front of participants, while the communication partner was holding in his hand the item corresponding to the figure to observe how would be the performance of the participants. The intervention occurred through the application of the PECS training associated with the VM. Before starting each application of PECS, participants watched a video in which appeared a colleague of 12 years without communication difficulties. For each phase were prepared three different videos. The videos lasted 20-30 seconds. Then it was started the application of the phases of the PECS. Results demonstrated that participants presented a good performance since the beginning of the PECS intervention associated with VM in addition to quick learning of communication skills provided in the training. It is possible to conclude that VM can be a rapid and effective technique for teaching communication skills through the PECS.
