Linguistic status subsequent to childhood immersion injury.

The linguistic abilities of two groups of children who had been involved in immersion incidents are reported--one group at 12 months after the immersion incident (n = 25), and the second group at five years after the immersion incident (n = 9). The performances of the two experimental groups on standardized language tests were compared with the performances of appropriate control groups that were matched for age, sex and socioeconomic status. The speech and language skills of the 12-months post-immersion group and the matched control group were assessed by means of the sequenced inventory of communication development. Subjects who were assessed 12 months after the immersion injury scored significantly lower results than did control subjects on receptive and expressive language ages that were calculated as percentages of the chronological age. No differences in language scores were evident between the subjects who were at five years after the immersion incident and their control subjects as assessed by the test of language development--primary. The language abilities of the victims of an immersion incident were correlated with their neurological status at presentation to hospital. The results suggest a need to monitor the linguistic development of all children who present initially in a coma after an immersion incident. The need for a longitudinal study of the linguistic abilities of these children is indicated.
