The aim of this study was to evaluate the comprehension level of czech sentences showing different syntactic complexity in children at family risk for dyslexia and children with specific language impairment – SLI (experimental groups) compared to typically developing peers (control group). The adapted version of TROG-2 (Bishop, 2003) was administered to 104 seven-year-old children.
Statistically significant differences were detected both between the SLI group and the family risk group and between the SLI group and the control group. On the contrary, no such effect was discovered between the family risk group and the control group.
The assumed descending tendency of achievement in at least 5 out of 6 test blocks was also substantiated. These results highlight the higher necessity of early language stimulation in children with SLI.
In order to prove relevancy of the respected conclusions a further research would be needed.
