Complexity Approach Resources

Complexity Approach for Families
These handouts provide an overview of the complexity approach to share with families in English and Spanish.

Applying Complexity Principles
This document provides an overview regarding how to apply complexity principles for children who present with mild articulation disorders, a primary difficulty with clusters or phonological disorders.

Sonority Sequencing Principle for Clusters (SSPC)
This resource displays a hierarchy of clusters that demonstrates that some clusters are more complex than others and that these should be targeted to create the most change.

Phonological Assessment and Treatment Targets Analysis Forms (English and Spanish)
These documents feature a step-by-step sequence that allows SLPs to fully describe and analyze each child’s phonological system in both English and Spanish.

High-Frequency Word List
This is a comprehensive word list that includes high-frequency words and high- and low-density words. Researchers continue to investigate the interaction between lexicon and phonology.

Implicational Language Laws
This document summarizes implicational language laws identified in linguistic research. SLPs can utilize these implicational relationships to target complex sound classes and sound structures, which leads to significant gains in a child's phonological repertoire.

Phonemic Inventory Worksheets
These worksheets (available in rows and columns) allow SLPs to identify each child’s phonemic inventory.

Naturalistic Play Activities
This resource includes play-based activities that yield maximum practice in natural contexts during treatment.
