Exploring the Potential of Matching-to-Sample-Based Training Protocols to Enhance Language Abilities in Individuals...

Area of Science:

• Speech and Language Therapy
• Developmental Psychology
• Applied Behavior Analysis

Background:

• Developmental Language Disorder (DLD) interventions include explicit and implicit methods.
• Matching-to-Sample (MTS) protocols are effective for equivalence-based learning but unexamined in DLD.
• MTS's incidental and implicit nature may mirror natural language acquisition.

Purpose of the Study:

• To conduct a scoping review of MTS-based language interventions in individuals with language impairments.
• To assess the potential of MTS for individuals with DLD.

Main Methods:

• Scoping review following PRISMA-ScR guidelines.
• Searched Web of Science and PsycINFO databases.
• Included 16 studies with 81 participants exhibiting language difficulties, often with co-occurring conditions.

Main Results:

• Most interventions targeted foundational receptive and expressive language skills.
• MTS reliably produced untrained (derived) stimulus relations, showing implicit learning efficacy.
• Small sample sizes, varied MTS formats, and lack of long-term follow-up limit generalizability.

Conclusions:

• MTS is a promising framework for DLD interventions.
• Controlled trials with standardized protocols and DLD-specific cohorts are needed.
• Future research should measure sustained, functional language gains.
