What happens when rhythms and phonemes collide?

Have you ever taught a child with weak phonological awareness? The differences between sounds are poorly defined and individually sounds are swapped around. A lack of phonological discrimination could be explained by conflation. Conflation, according to the OED is the merging of two or more sets of information, texts, sets of ideas etc into one.

One of the most fascinating aspects of conflation is that it can happen at different levels of conscious awareness. So, for example teenagers learning facts about physics might conflate words such as conduction and convection. After all, these terms look similar on the page and both are types of energy transfer.

Younger children might conflate colours such as black and brown as both begin with the same phoneme and are dark colours. The rapid colour naming test in the Comprehensive Test of Phonological Processing reveals such conflation. For instance, a child I assessed once as part of a reading intervention conflated brown and green. Any brown or green square in the assessment was named ‘grouwn’ (it rhymed with brown). She had conflated the consonant blends of ‘br’ and ‘gr’ and invented a name for both colours.

In the early stages of reading, conflation can underpin confusion between consonant digraphs such as ‘ch’ and ‘sh’. Another typical conflation is ‘th’, and ‘ph’ (and ‘f’). In all of these examples, the sounds are similar and they differ only on their onset - the very beginning of the sound.

A child with sensitivity to rhythm is attuned to the onsets of the smallest sounds of language. In terms of rhythmic precision, the front edge of the sound is also the point at which the rhythmic boundary occurs. Children with a well-developed sensitivity to rhythm are also attuned to phonemes and are less likely to conflate the sounds. Logically, cultivating sensitivity to rhythm would help children to detect the onsets of phonemes at the early stages of reading. Stay tuned for Part 2 and a free infographic..

The notion that sensitivity to both rhythm and the smallest sounds of language overlap in terms of has been around for decades and has been supported by research. 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 - and this principle applies to musical sound too. Sensitivity to rhythm is detected at the very start of a sound.

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.
