ABSTRACT

Background & Objectives
The present study investigated the differences in nonlinguistic performance between 4- to 6-year-old children with specific language impairment (SLI) and 2 groups of typically developing children; one matched by their language age (N-LA), and the other matched by their chronological age (N-CA) with the SLI children. Thirtynine children (13 SLI, 13 N-LA, and 13 N-CA) participated in the present study.
Methods
The experiments were conducted with 4 basic nonlinguistic tasks: (1) simple bar-pushing after auditory stimuli, (2) simple bar-pushing after visual stimuli, (3) choice bar-pushing after auditory stimuli, and (4) choice bar-pushing after visual stimuli. Three-way repeated ANOVA and One-way ANOVA were adopted to test for statistically significant differences.
Results
Results were as follows: (1) The correct rate of reaction was significantly different among the 3 groups in auditory and visual tasks. The performance of the SLI group was significantly lower than the N-CA in all tasks. No significant differences were found between the SLI group and N-LA group. (2) Significant differences were revealed in 3 types of tasks (auditory simple, visual simple, and visual choice). (3) The response latency was significantly different among the 3 groups in auditory tasks. The performance of the SLI group was significantly slower than the N-CA in auditory simple and choice tasks. No significant differences among groups in visual tasks were found. (4) The analysis of correlation was not significant between correct response rate and response latency. (5) Overall pattern of correct response rate and response latency were qualitatively similar across the 3 groups.
Discussion & Conclusion
The results of the present study show that children with SLI have more difficulty in nonlinguistic performance compared with N-CA. The present results suggest the lower correct rate and slower reaction time of the SLI group of children than the normal groups are characteristic of many children with SLI.
