For example, if a language has affricates, then it has to also have fricatives. There are language universals (or rules) that help determine which sounds are considered more complex. Markedness is based on implication rules for languages. The reasoning for this is that by definition, later developing sounds are more complex than early acquired sounds. So, for example, if you have a choice between B and SH, go with the SH sound as that sound typically develops after the B sound. Later acquired phonemes means choosing the sounds that typically develop later in a child’s speech system. Again, the theory is that if the child is stimulable for a sound, he already has some “knowledge” of this sound and it is not likely to create as much change in his phonological system if you target it. Don’t choose targets the child is easily stimuable for. (There is a continuum of phonological knowledge, but that’s for another post). The theory is that by choosing sounds that the child does not use yet on his own, you will affect greater change on the entire phonological system, more so than if you had targeted a sound he somewhat “knows” already. Least productive phonological knowledge simply means sounds that the child doesn’t produce at all, sounds that are not in his system currently. I am going to break down what each one of these things means. Generally you want to consider 4 things: (1) sounds the child has least productive phonological knowledge of, (2) nonstimulable phonemes, (3) later acquired phonemes, and (4) marked phonemes and clusters. So how do you choose complex targets for your children with phonological disorders? Well, it could be slightly different for every child. So let’s discuss how you choose targets when using a complexity approach in your speech therapy sessions. The speech language pathologist can help facilitate greater system-wide change in the child’s phonological system FASTER! You basically get more progress in less time while also working on fewer sounds directly! Sounds like a dream, right? What’s the rationale for using more complex, later developing sounds as targets in your speech therapy sessions? The basic idea is that by targeting more complex or “marked” sound classes (like clusters or affricates) then less complex or “unmarked” sound classes (like fricatives or stops) are also likely to be acquired indirectly! Using the concept of complexity and/or a “complexity approach” in my speech therapy activities has been a GAME changer with my students with moderate-severe phonological disorders.

Colleagues everywhere are welcome to join the private Facebook group E3BPforSSD for professional discussion of speech development and disorders.Complexity Approach for Speech Therapy Overview Please read the policy on questions from SLPs/SLTs on child speech assessment and intervention. The site is made possible through the kindness of donors.

Its mission is to provide useful, theoretically sound, and where possible evidence-based information about the assessment and treatment of human communication disorders. The site's intended audience is families and others close to children with voice, speech, language, literacy, and fluency difficulties, and people working in the field of communication sciences and disorders. Children's Speech Sound Disorders, 3rd ed., Wiley-Blackwell. She is also interested in developmental language disorder, the role of families in intervention, and evidence-based practice vs. She retired from clinical practice in 2011, maintaining her interests in presenting CPD and writing about children's speech sound disorders ( 2023 book). The content reflects the professional, clinical and teaching activities and small body of research ( ORCiD) of the site owner, Caroline Bowen. Welcome to the home page of Dr Caroline Bowen's Since 1998 has provided information and resources to Speech-Language Pathologists / Speech and Language Therapists, students, and consumers of SLP/SLT services worldwide.
