Abnormal language feature Pronoun reversal 2022-03-02T16:13:45Z Atypical language features characterized by first vs. second or third person pronoun errors such as using 'you' or 'he/she' in place of 'I'. These errors are attested in normal toddlers' spontaneous speech, albeit at varying rates; pronouns typically emerge around 1.5 years of age and reversals are most common before 2.5 years. A higher rate of pronoun reversal may be expected of people with autism spectrum disorder.
