Abstract: Objective To explore impacts of vocal rehearsal and retention duration on novel word naming in children with specific language impairment (SLI). Methods November to December, 2017, 45 children from kindergartens were selected in SLI group (n = 15), physiological age matching group (n = 15) and language ability matching group (n = 15). A three-factor mixed experimental design was used to investigate the effects of three factors: groups, vocal rehearsal (with/without) and retention duration (ten seconds/five minutes). Results The main effects of groups (F = 3.706, P < 0.05), vocal rehearsal (F = 25.570, P < 0.001) and retention duration (F = 226.746, P < 0.001) were significant. The interaction effects of vocal rehearsal×retention duration (F = 22.808, P < 0.001) and retention duration×groups (F = 3.739, P < 0.05) were significant. The interaction effects between other factors were not significant. Conclusion There are novel word naming learning defects in SLI children. However, the vocal rehearsal strategy may promote novel word naming learning and reduce the decline of novel word phonological information in short-term memory, to improve the phenomenon of novel word naming defects.

Key words: specific language impairment, novel word naming learning, vocal rehearsal, retention duration
