Research has suggested that auditory temporal integration (ATI) may play a role in language development. Using standardized tests of language and nonverbal intelligence and a computerized task requiring the child to make a decision about the speed of two chirps between birds, we measured the language, nonverbal intelligence and ATI threshold of 15 7-13 year-olds with language impairment (LI), 19 7-13 year-old aged-matched controls and 28 5-6 year-old language-matched controls. The computerized task estimated the child’s ATI threshold using a staircase procedure based on accuracy. The children with LI had significantly lower language scores than both control groups, and the groups did not differ in their nonverbal intelligence. There were no group differences in ATI threshold. Pearson correlation revealed significant correlations between ATI threshold and chronological age, but no significant correlations between ATI and language ability or nonverbal intelligence. These results do not support the theory that ATI is related to language development and disorders.
