This study tested the effectiveness of a morphological training program on children's learning and retention of exposed words and morphologically related unexposed words compared with…

We investigated the sensitivity of children with SLI to the consistent spelling of root morphemes, a feature to which young typically developing children demonstrate sensitivity. We asked children with SLI and two groups of typically…

This study examines the effect of morphological instruction and synthesizes instructional methods from 30 morphological interventions into four recommended morphological instructional strategies. Results suggest children receiving morphological instruction performed significantly better on measures of literacy achievement, especially in the areas…
