It has been hypothesized that sentence complement comprehension is a prerequisite for the development of false belief understanding in young children. Previous research has suggested that training on sentence complements leads to improved false belief performance. This study used a case study design to investigate the effect of sentence complement training on false belief for 2 children. One was a 3-year-old twin girl with typical language development; her twin sister was included, without

The twins demonstrated sentence complement mastery from the outset of the study, but did not display full competence with false belief. The child with a language delay improved markedly in comprehension of sentence complements but consistently failed false belief tasks. The results suggest that although sentence complement comprehension may play a role in false belief development, the relationship between the two may not be as close as has been suggested.
