The aim of this paper is to provide information regarding diversity in speech and language profiles of individuals with Autism Spectrum Disorders (ASD) and try to classify these profiles according to the combination of the communication difficulties. Research findings confirm the existence of heterogeneity of communication challenges in ASD across the lifespan. A lot of children with ASD experience communication challenges and strengths across all language sub-systems including pragmatics, grammar, semantics, syntax, phonology, and morphology in both oral and written language, while some children with autism demonstrate exceptional language abilities incl. linguistic creativity. Communication issues vary on a continuum of severity so that some children may be verbal, whereas others remain non-verbal or minimally-verbal. The diversity of profiles in speech and language development stem from either the presence of comorbid factors, as a core symptom of autistic behavior without comorbidity or both, with the development of complex clinical symptoms. Difficulties with the semantic aspect of language affect the individual’s skills in abstract thinking, multiple meanings of words, concept categorization, and so on. Finally, the coexistence of ASD with other communication difficulties such as a Language Disorder, Apraxia of Speech, Speech Sound Disorders or/and other neurodevelopmental disorders raises the need for examining more carefully the emergence of new clinical profiles and clinical markers useful in performing differential diagnosis and different intervention.

Background/Aims: One of psychology's challenges is to develop and evaluate sensitive tests in the area of social cognition. Yet, there are few available scales that can measure mild deficits in social understanding, especially for typically developing (TD) populations. The Reading the Mind in the Eyes Test (children's version) was translated and adapted for use in the Greek language [RMET-G (child)]. The aim of this study was to examine in the Greek language the qualitative and quantitative differences between TD youngsters and those with high-functioning autism (HFA), as well as the difference between TD children and TD adults. Methods: An interview-based psychometric study was conducted. Participants completed the RMET-G (child), constituting 3 groups: TD children older than 8 years, children with HFA and TD adults. Results: 103 participants completed the study. The results demonstrated that TD adults scored slightly higher than TD children, and children with HFA scored lower than their TD peers. Children with HFA, however, were able to recognize many of the pictures shown in the test. Conclusion: The results of this study, which were the first to be conducted in the Greek language, confirm findings of other studies in the literature conducted with the RMET in the English language.
