The research found that children who engaged in a voluntary imagination intervention showed significant improvement in language comprehension.
Research by University of Cambridge academics found that children as old as five or six struggle to reconcile inference and perspective, leading to difficulties in conversations. Combining these skills is crucial for understanding 'implicatures' - inferences made in conversation when people mean more than they say.

Infants with ASD exhibit significantly fewer social and early speech skills than their typically-developing peers at 9 months of age.
A study by NYU Steinhardt Professor Eric S. Jackson found that adults who stutter do not stutter during private speech, suggesting a strong social component in stuttering. The 'talk-alone-effect' is real and is influenced by the perception of being heard by a listener.
