4 Social Communica-on Disorder (SCD) an impairment of pragma-cs and is diagnosed based on difficulty in the social uses of verbal and nonverbal communica-on in naturalis-c contexts, which affects the development of social rela-onships and discourse comprehension and cannot be explained by low abili-es in the domains of word structure and grammar or general cogni-ve ability. B. The low social communica-on abili-es result in func-onal limita-ons in effec-ve communica-on, social par-cipa-on, academic achievement, or occupa-onal performance, alone or in any combina-on. C. Rule out Au-sm Spectrum Disorder (ASD). Au-sm Spectrum Disorder by defini-on encompasses pragma-c communica-on problems, but also includes restricted, repe--ve pa[erns of behavior, interests or ac-vi-es as part of the au-sm spectrum. Therefore, ASD needs to be ruled out for SCD to be diagnosed. D. Symptoms must be present in early childhood (but may not become fully manifest un-l social demands exceed limited capaci-es). The new DSM-5 category requires persistent difficul-es in verbal and nonverbal communica-on in social secngs, manifested by all of the following There are deficits in social communica-on, such as gree-ng or sharing informa-on in an appropriate manner. There is difficulty with changing communica-on to match the listener (e.g., an adult versus a child) or the context (e.g., classroom versus playground). Stereotypic or formal language may be inappropriately used for informal conversa-on. There is difficulty with the rules governing conversa-on, such as speaking in turn, repea-ng informa-on if not clearly understood, and regula-ng conversa-on in response to verbal and nonverbal informa-on from others. 4

5 Inference of what is not explicitly stated may not be made, or language with ambiguous meaning may not be correctly interpreted, such as metaphors or jests. These problems must cause func-onal limita-ons in effec-ve communica-on, social par-cipa-on, rela-onships and academic or occupa-onal performance, either individually or in combina-on. The symptoms must begin in the early developmental period, when language is usually acquired, and must not be be[er accounted for by another mental disorder or a general medical or neurological condi-on. In par-cular, cogni-ve impairment causing low abili-es in the domains of word structure and grammar cannot be the cause, and developmental delay, intellectual disability and au-sm spectrum disorder must be excluded. Aims of the study Collec-on of data related to pragma-c abili-es of children with au-sm and mild learning difficul-es (mental retarda-on). Comparison of pragma-c abili-es of children with ASD with children with Down syndrome and mild learning difficul-es (mental retarda-on) and also with children with typical development Collec-on of data related to typical development of Greek children Examina-on of the nature of pragma-c abili-es in children with ASD Par-cipants 12 boys with au-sm 12 boys with Down syndrome 22 boys with typical development Prerequisites: Their na-ve language was Greek The au-sm and Down syndrome subjects had mild learning difficul-es 5

6 Diagnos-c tools Criteria of DSM-IV for diagnosis of ASD (APA 1994) Revised-Au-sm Diagnos-c Interview (ADI-R) (Le- Couter, Ru[er, Lord 1995) Childhood Au-sm Ra-ng Scale (CARS) (Schopler, Reichler, Renner 1972) WISC-R (Wechler 1974) Pragma-cs Profile of Early Communica-on Skills (Dewart & Summers 1988). Test of Recep-ve and Expressive Language Abili-es (Vogindroukas, Grigoriadou 2009) PPECS Is an informal interview with parents concentrated on four main areas of pragma-cs, 1. Communica-ve inten-on 2. Response to communica-on 3. Par-cipa-on in social interac-on 4. Communica-on context There are 33 ques-ons which exam 43 pragma-c abili-es, the ques-ons are amplified by examples to s-mulate discussion. Ages of the par-cipants Age in months TD 66 ASD 84 DS 96 6

They are able to: Seek a[en-on of an adult Direct a[en-on Request Object Request Ac-on TD, Request for help verbally 94.8 Name objects Comment on object Comment on absence of an object Express independence Understand poin-ng Understand the inten-on of speaker in single direc-on Understand the inten-on of speaker in a single ques-on Understand indirect requests ASD, 48.7 DS,

11 This finding is in agreement with findings from other research which conclude that the statement that children with au-sm are presented as non communica-ve is not valid (Cantwell & Baker 1987, Wetherby 1986) Conclusion III The pragma-cs abili-es in children with ASD mostly relate to helping their needs and not to social communica-on needs Also the qualita-ve analysis of the results shows some differences between the three groups of par-cipants which relate to the way of using these abili-es Examples Asking for help: they ask for help in the same way in all situa-ons and without conveying more informa-on about the reason which leads them to ask for help Refusing: they don t always refuse by using the appropriate phrases, but mostly by pushing away the object or by going away from the place Expression of independence: most of the par-cipants use phrases which are different from the control groups phrases. The control groups par-cipants use phrases such as alone, I can do this myself. Children with ASD give direc-ons to the adults in order to do something alone such as go away leave me 11

12 Last thoughts Regarding the nature of the pragma-c difficul-es in children with ASD we conclude that these are observed as much in verbal communica-on as in non verbal According to our knowledge of au-sm perhaps we can use the term pre verbal pragma-cs in order to understand be[er the nature of pragma-c difficul-es in au-sm and also the concept of spectrum 12
