We apply this technique to a sample of 111 children between the ages of four and eight: 42 typically developing children (\n TD<\/jats:styled-content>\n ), 19 children with specific language impairment (\n SLI<\/jats:styled-content>\n ), 25 children with autism spectrum disorders (\n ASD<\/jats:styled-content>\n ) plus language impairment (\n ALI<\/jats:styled-content>\n ), and 25 children with\n ASD<\/jats:styled-content>\n with normal, non\u2010impaired language (\n ALN<\/jats:styled-content>\n ). The results indicate robust differences in echolalia between the\n TD<\/jats:styled-content>\n and\n ASD<\/jats:styled-content>\n groups as a whole (\n ALN<\/jats:styled-content>\n \u2009+\u2009\n ALI<\/jats:styled-content>\n ), and between\n TD<\/jats:styled-content>\n and\n ALN<\/jats:styled-content>\n children. There were no significant differences between\n ALI<\/jats:styled-content>\n and\n SLI<\/jats:styled-content>\n children for echolalia or self\u2010repetitions. The results confirm previous findings that children with\n ASD<\/jats:styled-content>\n repeat the language of others more than other populations of children. On the other hand,\n self\u2010repetition<\/jats:italic>\n does not appear to be significantly more frequent in\n ASD<\/jats:styled-content>\n , nor does it matter whether the child's echolalia occurred within one (immediate) or two turns (near\u2010immediate) of the adult's original utterance. Furthermore, non\u2010significant differences between\n ALN<\/jats:styled-content>\n and\n SLI<\/jats:styled-content>\n , between\n TD<\/jats:styled-content>\n and\n SLI<\/jats:styled-content>\n , and between\n ALI<\/jats:styled-content>\n and\n TD<\/jats:styled-content>\n are suggestive that echolalia may not be specific to\n ALN<\/jats:styled-content>\n or to\n ASD<\/jats:styled-content>\n in general. One important innovation of this work is an objective\n fully automatic<\/jats:italic>\n technique for assessing the amount of repetition in a transcript of a child's utterances.\n \n Autism Res<\/jats:bold>\n 2013, \u25cf\u25cf: \u25cf\u25cf\u2013\u25cf\u25cf.\n <\/jats:italic>\n \u00a9 2013 International Society for Autism Research, Wiley Periodicals, Inc.\n <\/jats:p>","DOI":"10.1002\/aur.1301","type":"journal-article","created":{"date-parts":[[2013,5,9]],"date-time":"2013-05-09T10:47:33Z","timestamp":1368096453000},"page":"372-383","source":"Crossref","is-referenced-by-count":67,"title":["Quantifying Repetitive Speech in Autism Spectrum Disorders and Language Impairment"],"prefix":"10.1002","volume":"6","author":[{"given":"Jan P.
