Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Late-acquired sounds, such as /r/ are difficult to learn and many children experience persistent errors on these sounds. The purpose of the present study is to determine whether treating these sounds earlier in the child's life may result in better outcomes.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Late-acquired sounds, such as /r/ are difficult to learn and many children experience persistent errors on these sounds. However, these sounds are often treated later in a child's life because they are not expected to be fully acquired until quite late--age 7-8 for some sounds. This practice places treatment in a time of the child's development in which they struggle to learn new sounds.The purpose of the present study is to determine whether treating these sounds earlier in the child's life may result in better outcomes, and to examine treatment efficacy and efficiency for two methods of treatment.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Motoric Arm

Children will participate in an intervention based on traditional articulation approaches to speech therapy.

Group Type ACTIVE_COMPARATOR

articulation therapy

Intervention Type BEHAVIORAL

children receive instruction in producing new sounds at the isolation, syllable and word level.

Phonologic Arm

Children will receive intervention that targets the conceptual representation of sounds.

Group Type ACTIVE_COMPARATOR

phonologic treatment

Intervention Type BEHAVIORAL

children receive instruction in producing new sounds at the word level
