“…One challenge common to all these interventions is maintaining engagement over the many hours of practice they require, particularly given that the interaction may not have any inherent appeal for the child. "The children with autism had been diagnosed using ADI-R and ADOS-G, [...] as high functioning autism" (Pioggia et al, 2007) Kaspar Low; robot is directly controlled by user "a six year old girl with severe autism," "a child with severe autism," "a 16-year old teenager with autism who is not tolerating any other children in any play or other task oriented activities" (Robins, Dautenhahn, & Dickerson, 2009) Keepon Intermediate; robot has a simplified body and simplified social behavior "At CA 1:11 (chronological age of 1 year and 11 months), her mental age (MA) was estimated at 0:10 by Kyoto Scale of Psychological Development", "MA 1:7 at CA 3:1; no apparent language", "MA/cognition 3:2 and MA/language 4:3 at CA 4:6" (Kozima, Nakagawa, & Yasuda, 2007) Nao Intermediate to high; robot speaks, blinks eyes, and plays a song game (Shamsuddin et al, 2012), or robot imitates child behavior (Tapus et al, 2012) "K can be classified as having high-functioning autism" (Shamsuddin et al, 2012); "cognitive abilities are equivalent of a 3 year old child and his language abilities of a 2 year old child"; "language abilities are equivalent to those of a 2 year old child, and his cognitive level of a 3-year old"; "language abilities are equivalent to those of a 1 and a half year old child, and his cognitive level of a 2 year old"; "severe mental retardation and he is nonverbal" (Tapus et al, 2012) Pleo Intermediate to high; dinosaur robot reacting to participants' prosody "ASD and control groups were well matched on verbal and cognitive abilities, with all participants having Verbal and Performance (or nonverbal) IQ above 70" (Kim, Paul, Shic, & Scassellati, 2012 (Vanderborght et al, 2012) QueBall Low; spherical mobile robot "One agitated autistic child"; "Several severely autistic children" (Salter, Davey, & Michaud, 2014) In contrast, technological interventions have been consistently found to hold a great deal of appeal for children with autism and allow them to maintain a "spirit of play" (Colby, 1973) while building social and communicative skills (Moore, McGrath, & Thorpe, 2000;Sansosti & PowellSmith, 2008;Swettenham, 1996;Tanaka et al, 2010;Wainer & Ingersoll, 2011). As the field of computing has advanced, robots have become an increasingly accessible technology, and research in the fields of socially assistive robotics (SAR) (Feil-Seifer & Mataric, 2012), autism therapy, and soci...…”
