Lego Robots & Autism Spectrum Disorder: a potential partnership?

Abstract

Individuals with autism spectrum disorder (ASD) present difficulties in developing social behaviours, in communicating gestural or verbally, and they may present some repetitive motor activities. The objective of this study was to improve social competences and to enable the transfer of acquired skills of five children with ASD and intellectual disabilities using a low-cost Lego robot as a mediator. The proposed methodology was divided in five phases: Familiarization, Pre-test, Practice, Post-Test and Transfer of Skills. The study ran in two sequential periods at different places. Each of these periods tackled different individual research questions and goals (taking into account the target group). During each period, the proposed methodology had to be adjusted according to the current context. Therefore, different experimental scenarios and corresponding specific goals had to be delineated. Results show that joint attention of the children increased over the sessions; and interaction with the researcher was verified. Furthermore, results show that there was an effective transfer of skills in the addressed case studies. This reinforces conclusions that robots seem, in fact, powerful tools that should be explored concerning this target population. But a more detailed study is required. The proposed methodology can be used by professionals and parents as a complement to common interventions.
