Abstract
This study is a randomized control trial aimed at testing the role of a human-assisted social robot as an intervention mediator in a socio-emotional understanding protocol for children with autism spectrum disorders (ASD). Fourteen children (4–8 years old) were randomly assigned to 10 sessions of a cognitive behavioural therapy (CBT) intervention implemented in a group setting either with or without the assistance of a social robot. The CBT protocol was based on Rational Emotive Behaviour Therapy (REBT) principles. Pre- and post-intervention assessments were conducted using the Test of Emotional Comprehension (TEC) and the Emotional Lexicon Test (ELT). Substantial improvements in contextualized emotion recognition, comprehension and emotional perspective-taking through the use of human-assisted social robots were attained.

Notes
In this paper, we have chosen to use the expression “on the autism spectrum” to describe children with a diagnosis of autism spectrum disorder according to DSM-5 (American Psychiatric Association 2013). This expression is widely accepted by professionals and stakeholders (Kenny et al. 2016) and avoids the person-first (person with autism or ASD) versus identity-first debate (autistic or ASD person). The children involved in our study are too young to choose for themselves how to self-identify and we do not feel comfortable choosing for them. Unless otherwise specified, in the following we will focus on individuals without intellectual disability, with functional language and with a DSM-5 symptom severity level of 1 or 2 on both DSM-5 domains.
