In my last post I described a typical challenge facing a child with poor phonological awareness. Using a rapid colour naming test (CToPP2), it’s possible to identify that a weakness in processing the smallest sounds of language often occurs at the onset of a phoneme, in other words the onset of a syllable. Consonant blends and consonant digraphs are more affected, so, conflation between ‘thr’ and ‘fr’, or ‘cl’ and ‘gl’ is likely to happen and to impede the development of reading with ease and fluency.
The notion that sensitivity to both rhythm and the smallest sounds of language overlap in terms of data has been around for decades. A positive correlation between sensitivity to rhythm and phonemic sensitivity has been shown in many studies. It’s easy to understand that rhythm and phonological processing overlap if we consider that the start of a phoneme - the onset of a syllable is exactly where sensitivity to rhythm is measured - whether that’s the start of a musical sound or a spoken utterance.
Thinking for a moment about words that begin with a consonant, imagine focussing mostly on the vowel sound of each syllable, without being able to discern the shape of the initial phoneme with sufficient clarity. The sounds would merge together into a kind of ambient speech puddle.
Vowel sounds carry interesting information such as emotion, or tone of voice. They are longer (in milliseconds) and without defined edges. Now imagine focussing on the onset of those syllables. The consonants are shorter (in milliseconds), more sharply defined and more distinctive, leaving plenty of headspace for cognitive control. If consonants are prioritised, information flows easily and the message lands with clarity.
The Rhythm for Reading programme addresses these distinctions through group teaching that is fun and supports early reading in particular. Information processing is enhanced by sensitivity to rhythm because rhythm focusses attention onto the onset of the sound, which is where the details are sharpest. This kind of information processing remain effortless, easy and fluent.
