Delayed Early Vocabulary Development in Children at Family Risk of Dyslexia

Results:  Repeated measures analyses showed that FR-dyslexic children  had  lower  receptive  vocabulary  scores  from  23  months onward  and  lower  expressive  scores  from  17  months  onward than  FR-nondyslexic  children.  Latent  growth  curve  modeling showed  lower  initial  growth  rates  in  FR-dyslexic  children, followed  by  partial  recovery,  indicating  a  delayed  increase in  receptive  and  expressive  vocabulary.  FR-nondyslexic and  TD  children  did  not  differ.
