Phonological Awareness


The evidence for developing Phonological Awareness skills in children is widespread. This month the Gameplan team set out to investigate the benefits of such skills for improving literacy in school age children.

What is Phonological Awareness?

Phonological Awareness (PA) refers to the ability to identify, segment, blend and manipulate sounds in words, as well as identifying the number of syllables. This is an essential skill for learning to read and has been shown to precede and predict successful transition from language to literacy. Many children with reading problems have difficulties with PA such as generating rhyming words, identifying the first sound in a word, identifying the number of sounds or syllables in a word, or adding or deleting sounds within words. Difficulties with PA skills can affect a student's ability to read words.

PA tasks follow a hierarchy, which may need to be explicitly taught in sequence:

Inside the brain

In a study by Kovelman et al (2011) four participant groups were studied using Functional Magnetic Resonance Imaging (fMRI) to identify areas of the brain that are recruited during Phonological Awareness tasks. Typically developing children recruit the left dorsolateral prefrontal cortex which may play a critical role in PA, whereas this study indicates that children with dyslexia have under-recruitment of left DLPFC and do not engage this region for phonological processing. Furthermore, activations in the left posterior temporal and parietal regions increase with age and reading proficiency, whereas these activations are often reduced in children with dyslexia.

This lack of significant activation suggests that children with dyslexia may develop a range of strategies associated with a variety of neural systems to support phonological awareness when the left DLPFC is not engaged. There are no common brain regions that are recruited consistently by the children with dyslexia. The study highlighted that there is likely a network of brain regions in charge of PA for speech processing.

Phonological Deficit hypothesis

Dehaene (in the seminal text Reading in the Brain) proposes that people with dyslexia have a basic deficit in processing the constituents of spoken words.  A phonological deficit refers to the difficulty in perception, retention, manipulation or production of speech sounds. This includes the difficulty in holding speech sounds in the memory store while completing tasks such as nonsense word repetition (e.g. fleptish), long and short word repetition and digit span. This deficit in speed of access reveals difficulties in rapidly naming pictures, colours and digits.

Castles and Friedmann (2014) argue that the majority of individuals with Dyslexia do display deficits of one of the range of tasks broadly considered to be measures of phonological skill. But to suggest that all Dyslexia is caused by a phonological deficit is incorrect. The researchers argue that phonological deficits alone are unlikely to account for all types of Developmental Dyslexia and other subtypes such as surface, attentional, letter position or hyperlexia must be considered in the diagnosis.

Improving verbal memory

A study by Park et al (2013) investigated the benefit of PA intervention on the improvement of working memory.  Grade 2/3 children with Specific Language Impairment (SLI) participated in the study. Past studies have found a strong relationship between language learning difficulties and verbal working memory in children with SLI.  Children with these difficulties find it challenging to hold sounds in their short-term memory, hence resulting in difficulties decoding words.

Students who received an extra 20 minutes of phonological awareness training during each language intervention session significantly improved their verbal memory (both short term and working memory). The study highlights that teaching PA skills past Grade 1 can still be very beneficial for improving decoding and verbal memory skills.

 Activities for home reading

There are multitude benefits stemming from PA training in primary school children.

Research has shown that even 10 minutes of PA activities during reading time with your child can improve their awareness of sounds in words. While reading, select some words your child may have difficulty reading, then prompt them to:

  • Generating rhyming words, e.g. “what times with ‘mouse?’”
  • Identify the syllables by clapping, e.g. “carefully” – care-fu-lly (3 syllables).
  • Identify the first, middle, last sound in words, e.g. “What’s the first sound in ‘road’?” (“r”)
  • Choose a couple of words and separate them into sounds, i.e. ask your child to say all the sounds in a word, e.g. “button” – b-u-tt-o-n.
  • Choose a word for the child to separate into sounds, then you blend the word back together.

Phonological Awareness is an important and necessary skill that can be developed at any age. For more information and suggested activities, please follow the links below.
