Abstract
Thirty-two 5-year-old children with specific languageimpairment (SLI) and 32 chronological age (CA) controls completed 4 tasksthat were considered potential positive markers for SLI.Children's performance on 2 linguistic tasks (past tense and noun pluralstask) and 2 processing tasks (nonword repetition and digit recall) wereexamined.This approach allowed the examination of more than 1 type of markersimultaneously, facilitating both comparisons between markers and also theevaluation of combinations of markers in relation to identifying SLI.Children with SLI performed significantly worse than CA controls in all 4marker tasks.Specificity/sensitivity analysis of the 4 marker tasks revealed nonwordrepetition and the past tense task to have the best overall accuracy atthe 25th and 16th percentile.Finally, stepwise discriminant analysis revealed nonword repetition andpast tense marking to be the best markers for identifying young childrenwith SLI.
