Enrollment: 16
Sex: ALL
Minimum age (years): 4
Maximum age (years): 8
Standard ages: CHILD
Accepts healthy volunteers: yes
Allocation: NON_RANDOMIZED
Intervention model: PARALLEL
Intervention model description: Young children (age 4-5) and Old children (age 7-8) will be enrolled in either a Motoric behavioral treatment arm or phonological treatment arm.
Primary purpose: TREATMENT

Brief summary: 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: 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.

Eligibility criteria: Inclusionary Criteria:

* Normal Hearing
* Typical Receptive Language
* Speech Sound Disorder
* No motor speech impairment
* Typical non-verbal intelligence
* Produces at least one late-acquired sound with \<7% accuracy
* Monolingual English-speaking
* Typical in terms of motoric and neurological development

Exclusionary Criteria:

* Neurological disorder
* Hearing loss
* Nonverbal IQ \< 16th percentile

Primary outcomes:
measure: Treatment Efficacy: Number of correct productions of treated speech sounds in treatment words
timeFrame: baseline until accuracy criterion is met; up to 18 weeks after final baseline session
measure: Treatment Efficiency: Number of sessions required to meet accuracy criteria
timeFrame: baseline until accuracy criterion is met; up to 18 weeks after final baseline session
measure: Session Length: Mean duration of sessions in minutes
timeFrame: First treatment session until final treatment session. Final treatment session occurs when accuracy of treatment sound is met (90% accuracy across three consecutive sessions or a maximum of 35 treatment sessions)
Secondary outcomes:
measure: Accuracy of production of untreated sounds measured on pretest and posttest probes
timeFrame: baseline and at posttest up to 18 weeks after final baseline session
