Due to their difficulties, young children with ASD often lack adequate early communicative exchanges. These early communicative exchanges are important for the development of inner speech as children grow older, as a person's communicative ability is strongly associated to the person's ability to think in words (Durham University, 2012). It is proposed that the lack of inner speech use in many people with ASD may be one of the contributing factors leading to some of the repetitive behaviours that people with ASD often display (Durham University, 2012). Another reason that inner speech may be important for people is that use of inner speech may increase mental flexibility in people. This is especially relevant to people with ASD because people with ASD often lack mental flexibility and often find changes in their environments disturbing and stressful. Findings from a study shows that although children with ASD's mechanism for inner speech is intact, they were able to use inner speech in short term memory recalling tasks such as word repetition; they usually do not use it in the same manner as their peers without ASD (Durham University, 2012). Furthermore, even though the autistic children participating in the study were verbally able, they did not use inner speech when solving problems and planning. This implies that there are distinct differences between verbal …show more content…
For quite a few of these people, social and communication problems may persist into adulthood. A study on young adults with ASD over a 12-months period finds that "almost 40 percent of youth with ASDs never got together with friends", half of them "never received phone calls or were invited to activities", and "28 percent were socially isolated with no social contact whatsoever" (Washington University in St. Louis,
