with SLI may not have produced any words yet by the age of two. This is generally the first indication that a child might have a language impairment ( Diepeveen Duseldorp, Bol, Murphy & Verkerk, 2015). In case they did produce words, these might be incomprehensible and sound like babbling. Concordantly, at later stages in life, children can struggle with learning new words and making conversations (Bruce, Hansson & Nettelbladt, 2010). When they reach the age of 7-8, they might still talk like a 3 year old, using simplified speech sounds that are grammatically incorrect (Bishop 2006). Being able to communicate is important to children, as it benefits their social and emotional development, for example to make friends. Children that are poor at communicating also tend to have poorer friendships and therefore show more withdrawn behaviour (Conti-Ramsden & Durkin, 2010; Fujiki, Hall, & Spackman, 2004)). Next to providing social benefits, communication also contributes to emotional development, as it provides children with the ability to express their feelings. Expressing their feelings to others is beneficial as other people are able to understand how they feel (Conti-Ramsden & Durkin, 2010).
Furthermore, the issue of SLI is not only important to children as language impairments tend to persist into later childhood, adolescence and early adult life’ (Clegg, Hollis, Mawhood & Rutter, 2005). Therefore it is necessary to obtain information about how SLI affects the emotional and social development of children to be able to intervene as soon as possible any social and emotional development delay the child might experience later in life.
