Researchers have found that frequency and variability of language input contribute to syntactic learning in these children, respectively. In this study, we investigated whether frequency and variabilities of verb exemplars could jointly facilitate learning of passive structure in children with DLD.We conducted our study with a non-randomized control-group pretest-posttest design. Twelve school-aged children with DLD (mean age 7;3) participated in a 6-week intervention, with shared book reading as primary activity and passive structure as intervention target (16 exposures for the structure per week). Children were evenly assigned to High Variability (HV) group or Mixed group. Out of the 16 exposures, the children in the HV group heard 16 verbs for once in passive structure, whereas the children in the Mixed group heard 2 verbs, repeated 5 times each, and 6 verbs for once. Our results showed that children in both groups improved on producing passive structures in a syntactic priming task, and also showed significant change in untrained verbs (p<.05). However, there were no group difference on picture pointing task after the intervention. More importantly, in story retell, children in the Mixed group not only produced more spontaneous uses of passive structures, but also showed greater gains on standardized test of syntax and MLU, suggesting learning and generalization of complex syntax. Consistent with previous studies, shared book reading could enhance syntactic complexity in story retelling in both groups. Our findings inform SLPs that frequency and variabilities of verb exemplars manipulation in a target structure could facilitate syntactic learning in school-aged children with DLD. The benefit of applying these input strategies in a syntactic form may boost treatment efficiency compared to simply increasing the input frequency of sentences.發展性語言障礙語法學習頻率範例變異性繪本共讀介入developmental language disorderfrequency effectexemplar variabilityinterventioncomplex syntaxthesis
