Which of the following represents a method of compensation for speech and language deficits?

The method that represents a compensation for speech and language deficits is represented by the child-based corrective device. This approach directly targets the child's specific speech and language challenges by providing tools or devices that assist with communication. These devices can improve the child's ability to express themselves and engage in conversation, helping them communicate more effectively despite their deficits.

In contrast, early literacy instruction primarily aims at providing foundational reading and writing skills rather than compensating for existing speech and language issues. Group therapy sessions may promote social interaction and language practice, but they do not directly serve as a compensatory strategy for individual deficits. Parental training programs, while supportive of skill development at home, are more about empowering parents to facilitate language growth rather than providing direct compensation for deficits. Thus, the child-based corrective device stands out as the most relevant method for compensating for specific speech and language deficits.
