Age-related Correlates of Treatment for Late-acquired Sounds

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.

About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

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

Treatment and study plan

articulation therapy

Behavioral

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

phonologic treatment

Behavioral

children receive instruction in producing new sounds at the word level

Primary outcomes

  1. Treatment Efficacy: Number of correct productions of treated speech sounds in treatment words

    Time frame: baseline until accuracy criterion is met; up to 18 weeks after final baseline session

    Accurate Production of treatment sound at baseline and at posttest

  2. Treatment Efficiency: Number of sessions required to meet accuracy criteria

    Time frame: baseline until accuracy criterion is met; up to 18 weeks after final baseline session

    Number of treatment sessions required to meet accuracy criteria (90% accuracy across three consecutive sessions or a maximum of 35 treatment sessions)

  3. Session Length: Mean duration of sessions in minutes

    Time frame: 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)

    Start and end time of session is recorded on scoresheet, then number of minutes for each session for each participant is found and the mean across all sessions is calculated.

Secondary outcomes

  1. Accuracy of production of untreated sounds measured on pretest and posttest probes

    Time frame: baseline and at posttest up to 18 weeks after final baseline session

    Some children may generalize their skills learned through treatment to sounds that were not treated in the trial.
