What intervention strategy aligns with the complexity approach for selecting targets for a child with limited sounds?

The complexity approach in speech-language intervention emphasizes selecting targets that are more complex than the child's current levels of production, which in turn encourages broader generalization across other sounds and language aspects. Targeting late-acquired sounds is a key element of this approach because these sounds are typically more phonetically complex and can promote change in the overall phonological system of the child. By focusing on these sounds, the child is not just learning to produce a specific phoneme, but they are also likely to improve their production of other sounds, facilitating a more comprehensive development in their speech abilities.

This strategy contrasts with selecting phonemes based on frequency or relevance to the child's life, as these could be easier sounds that might not stimulate the same level of generalization or progress in overall speech skills. Prioritizing frequently heard sounds, while helpful in some contexts, does not take full advantage of the potential benefits of targeting complexity to foster greater growth.
