Understanding phonological processes in 3–7-year-olds: What’s typical and when to seek help

ByLondon Speech and Feeding
| |

As a speech and language therapist, one of the most common questions I hear from parents is:

‘They can talk, but their speech still sounds immature. Is this normal?’

Many children between the ages of three and seven use speech patterns that make their words sound different from adult speech. These patterns are known as phonological processes, and for younger children, they are a normal part of speech development.

However, when these processes persist beyond the expected age, they can start to affect clarity, confidence and learning, especially once children enter school.

This blog will help you understand:

  • what phonological processes are
  • which patterns are typical at different ages
  • and when it might be time to seek speech therapy support

What are phonological processes?

Phonological processes are patterns of sound simplification that children use while their speech system is developing.

Instead of learning each sound one by one, children initially organise sounds into patterns that make speech easier to produce. This is a normal and efficient strategy for a developing brain.

For example:

  • saying ‘tar’ instead of ‘car’
  • saying ‘poon’ instead of ‘spoon’
  • saying ‘bud’ instead of ‘bus’

These are not ‘bad habits’. They are part of how speech develops.

The key question is how long these patterns last.

Common phonological processes (and when they usually disappear)

Below are some of the most common processes parents notice in 3–7-year-olds.

1. Final consonant deletion

Leaving off the last sound in a word

  • ‘ca’ for cat, ‘da’ for dog
  • Typically resolved by 3–3½ years

2. Fronting

Replacing back sounds (k, g) with front sounds (t, d)

  • ‘tar’ for car, ‘do’ for go
  • Typically resolved by 3½–4 years

3. Cluster reduction

Omitting one sound in a consonant cluster

  • ‘poon’ for spoon, ‘top’ for stop
  • Typically resolves by 4–5 years (some clusters slightly later)

4. Gliding

Replacing /R/ or /L/ with /W/ or /Y/

  • ‘wabbit’ for rabbit, ‘yion’ for lion
  • Can be typical up to 5–6 years

5. Weak syllable deletion

Leaving out unstressed syllables

  • ‘nana’ for banana
  • Usually resolved by 4 years

If these patterns continue past the expected age, speech can remain difficult to understand particularly for unfamiliar listeners such as teachers, peers, and also Auntie Karen or grandparents who visit once in a while.

Why phonological processes matter in school-age children

By the time children reach reception and Year 1, speech clarity becomes increasingly important.

Persistent phonological difficulties can affect:

  • being understood by teachers and peers
  • phonics and early reading
  • spelling
  • confidence in speaking
  • willingness to participate in class

Some children become aware that they ‘sound different’ and may speak less, avoid longer words, or become frustrated when misunderstood.

What’s the difference between a delay and a disorder?

This is an important distinction.

  • A phonological delay means a child is following the normal pattern of development, just more slowly.
  • A phonological disorder means the child is using atypical patterns, or continuing age-expected patterns well beyond when they should have resolved.

A speech and language assessment helps identify:

  • which processes are present
  • how many are affecting speech
  • how consistent the errors are
  • and whether intervention is needed

Signs it may be time to seek speech therapy

You may want to seek professional advice if your child:

  • is 3½ years or older and still hard to understand
  • is understood well by family but not by others
  • becomes frustrated or avoids talking
  • has difficulty with phonics or spelling
  • uses several phonological processes at once
  • has not made progress despite time and encouragement

Early support does not mean something is ‘wrong’. It simply helps speech development move forward more efficiently.Research consistently shows that unresolved phonological processes beyond the expected age can impact intelligibility, literacy and confidence (Dodd, 2014; Bowen, 2015).

How speech therapy helps phonological development

Phonological therapy is not about drilling individual sounds endlessly.

Instead, therapy focuses on:

  • helping children recognise sound patterns
  • building awareness of contrasts (e.g. ‘tar’ vs ‘car’)
  • practising speech in meaningful, playful ways
  • supporting generalisation so progress carries into everyday speech

For school-aged children, therapy is usually structured, motivating and highly targeted and progress can be very encouraging.

A final reassurance

Many children with phonological difficulties go on to develop clear, confident speech with the right support.

If you’re unsure whether your child’s speech is ‘just a phase’ or something that needs attention, a professional assessment can give clarity and peace of mind.

    Dynamic assessment – Let’s look beyond the checklist

    ByLondon Speech and Feeding
    Dynamic assessment – Let’s look beyond the checklist

    As a parent, you’re always observing your child, celebrating his or her milestones, and sometimes, wondering if he or she is quite on track. When it comes to speech, language, play, attention, and listening, these early years are a whirlwind of development! It’s natural to seek guidance if you have concerns, and that’s where a truly comprehensive assessment comes in.

    But what exactly does ‘comprehensive’ mean, especially when it goes beyond a typical checklist? You can find any number of check lists online these days but whilst they can give you an overall idea of what a child is typically expected to do at any given age, it can also start leading you into a rabbit hole of anxiety of ‘what-iffery’.

    At The London Speech and Feeding Practice I believe in something far more insightful than a static evaluation: Dynamic Assessment. Think of it as an in-depth, interactive investigation into your child’s unique communication landscape, exploring not just what he or she can do, but how he or she learns and why he or she might be facing challenges. This is so important.

    What makes an assessment ‘dynamic’?

    Imagine trying to understand a child’s personality by just looking at a single photograph. It gives you a glimpse, but it hardly tells the whole story. Traditional, formal assessments, while valuable, can sometimes be like that photograph – a snapshot of skills at one specific moment.

    Dynamic assessment, on the other hand, is a living, breathing process. It’s called ‘dynamic’ because:

    • It’s interactive and responsive: It adapts to your child’s needs in real-time. It’s not about sticking rigidly to a pre-set schedule of tests. Instead, it’s about observing, gently prompting, and providing support to see how your child responds and learns. This allows me to understand his or her learning potential, not just his or her current performance.
    • It’s holistic and multi-faceted: I look at the whole child. We delve deep into not just speech and language, but also his or her play skills (a crucial window into cognitive and social development), attention and listening abilities, and his or her social engagement. These areas are intricately linked, and a delay in one can often impact others.
    • It integrates multiple perspectives: Your insights as a parent are invaluable! Before we even meet, my comprehensive onboarding questionnaire gathers essential background. During the assessment, your feedback, observations, and comments are woven into the fabric of our session. You are the expert on your child, and your voice is central to forming a complete picture.
    Dynamic assessment – Let’s look beyond the checklist

    More than just ‘speech’: A deep dive into development

    You might initially be concerned about your child’s speech sounds, or perhaps his or her ability to form sentences. These are vital areas, but my approach goes much further. I’m keen to understand:

    • The ‘why’ behind the ‘what’: Is a child struggling with language because of difficulties with understanding instructions (receptive language), or with expressing themselves (expressive language)? Are his or her attention skills impacting his or her ability to follow a conversation? Is his or her play demonstrating imaginative thought, or does he or she prefer more structured, repetitive activities? These nuances are critical.
    • Differential diagnosis: This is where the skill of an experienced clinician truly comes into its own. Through dynamic assessment, I can differentiate between a developmental delay (where a child is following a typical progression but at a slower pace) and a disorder (where his or her development is following an atypical pattern). This distinction is vital because it guides the type of support and intervention that will be most effective. Understanding the cause of the delay or disorder is paramount to creating a targeted, impactful therapy plan.

    The art of observation

    While I draw upon evidence-based practice as well as a formal, standardised assessment as well as my extensive clinical knowledge, I also rely heavily on the art of observation. From the moment your child walks into the room, I’m establishing rapport, engaging them in play, and creating a safe, fun environment. It’s through this genuine interaction – often without them even realising they’re being ‘assessed’ – that the most authentic insights emerge.

    This is where the magic happens:

    • Building rapport: A child who feels comfortable and connected will show you so much more of his or her true abilities and personality. I pride myself on creating an atmosphere where children can relax and simply be themselves.
    • Play as a window: Play isn’t just fun; it’s a child’s natural language. It reveals his or her understanding of the world, his or her problem-solving skills, his or her social engagement, and his or her ability to use symbols and language.
    • Skilled interpretation: My years of experience allow me to see beyond surface-level behaviours and interpret the subtle cues that might indicate underlying strengths or challenges. This goes far beyond what any standardised test alone can capture.

    Why choose a clinician who offers dynamic assessment?

    In essence, a dynamic assessment provides a rich, nuanced, and truly personalised understanding of your child. It’s an investment in:

    • Accuracy: Leading to a more precise diagnosis and understanding of his or her unique profile.
    • Tailored support: Enabling the creation of highly individualised therapy goals that truly meet your child where he or she is and gently guide him or her forward.
    • Empowerment: You’ll leave with not just answers, but also practical strategies and a clear path forward, feeling confident and informed.

    If you’re seeking a thorough, empathetic, and truly insightful assessment for your child’s communication development in London, I invite you to get in touch. Let’s work together to unlock your child’s full potential.

    Discover how Attention Autism can support your Autistic child’s communication

    ByLondon Speech and Feeding

    “I’ve got something in my bag, in my bag, in my bag,

    I’ve got something in my bag,

    what it is”

    You might be wondering why your Speech and Language Therapist is singing this song and then presenting items from a zipped-up bag. Let me take you through stage one of this evidence-based approach.

    There are many aims of ‘bucket or bag time’. During stage one, you are simply engaging your child’s attention (whilst also exposing them to language). It’s important to remember that you are not forcing your child to say or do anything. The idea is that the items in the bag or bucket ‘offers an irresistible invitation to learn’ (Gina Davies, 2020).

    You don’t need ‘special’ expensive toys. Use what you have at home. It might be that you have some bubbles, a wind-up toy. You might have some foil that you can roll up into a ball, or a balloon. Keep these items for ‘bucket time’. This means that your child is likely to be excited and motivated for the activity. The only stipulation is that these items must be highly motivating and must be the most exciting thing in the room. You’ll want to cover up any distractions.

    So, you have your items and your opaque zipped bag, next you’ll want to put the items into the bag ensuring the zip is closed. The zip is important as it increases suspense and excitement as your child cannot see inside. You can also comment when unzipping ‘open bag’ using the signs ‘open’ + ‘bag’ to support your child’s understanding. Your Speech and Language Therapist can help with any Makaton signs that are unknown. The idea of this activity is that the item isn’t touched by your child. This can seem a little odd or feel “mean” but there is a reason for this: we want our child to look at us as well as the object or toy. As soon as we allow our child to touch and play with that toy their attention will go to the toy alone and we won’t get JOINT attention or engagement. This is the reason why we SHOW interesting things for a brief moment and then put these items back into the bag or bucket and out comes the next item. If your child wants to grab the toy and gets upset, then they may not be quite ready for this approach.

    Next, we sing the song (as above) and unzip the bag taking out one of the items. The use of pausing is important. Pause after the song: does your child try to use gesture or sound? You can also use this opportunity to model short phrases, ideally one or two words such “it’s a spinner! Wow… so many colours”. After a couple of turns, repeat the process and pull out a different item. We tend not to sing the song each time for the next item. Just sing it at the beginning and then get on with producing the amazing, wonderful things in your bag. No hard and fast rules though, apart from “don’t let the child touch the toys”.

    The biggest factor here is that you and your child enjoy the activity together. Have lots of fun!!

    Cued Articulation – using hand gestures to show how a sound is made

    ByLondon Speech and Feeding
    Watch how cued articulation can transform your child’s speech and language skills!

    Cued Articulation involves using specific handshapes and placement cues to guide the speaker’s articulators, such as the tongue, lips, and teeth, to produce accurate sounds. It was originally conceptualised by Jane Passy, a speech-language pathologist. But it is important to know that we can, and often do, also use other speech cues which help our student visualise what they need to do. In other words, we can mix and match our cue pictures depending on what works best with each student.

    In the beginning of my speech therapy practice I would stick religiously to Jane Passy’s method but over the years I have learned and used many different visual hand cues which all have worked with individual students.

    It is important to remember that this is not an exact science, rather than an art! The art is to find the key to each individual student’s understanding and inspire motivation to try out a sound which they find hard to do.

    As an example, the hand signs used by Caroline Bowen’s method, an Australian Speech-Language Pathologist, are quite different to Jane Passy’s signs but they can equally work very well. Caroline Bowen’s visual for the /r/ sound is the ‘rowdy rooster’ — a crazed rooster on a motorbike — and the hand signal is that of revving up the motor bike engine with both hands whilst trying out the /r/ sound! I have a good handful of students who really loved this rooster image and were able to eventually produce a good /r/ using this cue.

    So, it is horses for courses with many things, and visual images and hand cues are no exception!

    Sound picture cards:

    Again, there are a host to choose from and I tend to collect a number of different images for each sound I want to practise with my student. As an example, below are a couple of different examples I use for the sound /p/:

    The Nuffield Programme suggests to use this popper card, which works well with a student who knows these poppers and perhaps has one on their trousers.

    As an alternative, and especially for younger students, I like using the Popper Pig Card – which I also have in my room so I can quickly show how it pops. Or we can have a popping game in between saying the /p/ sound at times. (The popper card is great as I can use the real toy to help with conveying the /p/ sound as it pops.)

    Each card has its own merit and I choose the right card for the individual student.

    How I use cued articulation and the visuals in Speech Therapy

    1. Cueing and practice: I introduce the appropriate card and handshapes for the targeted sounds. We then practise producing the sounds.
    2. Reinforcement and feedback: Positive reinforcement encourages progress and builds confidence.
    3. Fading out the cues: Once my student is able to say the sound more easily, we can gradually fade out the speech cues.

    Benefits and effectiveness

    Using Cued Articulation and Speech Image Cards has been shown to be effective in improving speech production for individuals with various speech and language disorders, including:

    • Articulation disorders: Difficulty producing specific sounds accurately.
    • Apraxia of speech: A motor planning disorder that affects the ability to sequence and coordinate movements involved in speech.
    • Phonology disorders or delays: Confusion and delays in how sounds are organised in categories to convey meaning, errors in sound patterns, for example front sounds are produced at the back, or long sounds are produced as stops.
    • Stuttering: A fluency disorder characterised by interruptions in speech, such as repetitions and prolongations.

    Tips for parents and student speech therapists

    Parents can play a crucial role in supporting the implementation of cued articulation at home and in therapy sessions. Here are some tips:

    • Collaborate with your SLT: Good feedback and communication with the Speech and Language Therapist creates consistency and progress..
    • Practise Regularly: Encourage consistent practice of cued articulation at home to reinforce learning.
    • Use Visual Aids: Use the same visuals that your therapist uses in the speech clinic to help your child at home with recall and practice.

    The purpose and nature of a speech and language therapy assessment

    ByLondon Speech and Feeding

    If you have ever wondered what happens when you bring your child to a speech and language therapy assessment, then this blog will shed light on the ins and outs of it for you.

    At its heart, a speech and language therapy assessment is a systematic and thorough evaluation of your child’s communication or eating/swallowing abilities. It’s more than just asking a few questions. It is a carefully constructed process designed to identify strengths, pinpoint challenges, and ultimately pave the way for effective intervention.

    Establishing a detailed profile – a few bullet points:

    • Identification of communication and swallowing difficulties: I aim to determine if a communication or swallowing disorder exists. I will establish if the difficulty is a delay or a more complex disorder.
    • Diagnosis of the specific disorder/autism: The assessment delves deeper to pinpoint the specific type and nature of the difficulty. For instance, is your child’s language delay due to a specific learning disability, a developmental delay, or another underlying condition?
    • Knowing the aetiology or what is causing a difficulty is crucial for targeted intervention. And whilst we are on the topic let’s talk about an autism assessment: I am trained and experienced in assessing and diagnosing autism. However, when it comes to the diagnosis of autism I provide a preliminary ‘working hypothesis’ rather than giving a definite final diagnosis. The reason for this is that it is considered the ‘gold standard’ and ‘best practice’ to diagnose autism in a multi-disciplinary setting and context. Since I work on my own, I always refer to highly recommended multi-disciplinary clinics for the ultimate diagnostic assessment.
    • Determination of severity: Understanding the severity of the difficulty is essential for prioritising intervention and measuring progress. Is your child’s difficulty mild, moderate, or severe? This helps me choose a particular approach and then tailor it to suit each individual child.
    • Identification of underlying strengths and weaknesses: An assessment doesn’t just focus on what’s wrong. It also highlights your child’s strengths and areas of relative ease. This information is invaluable for building upon existing skills during therapy. Understanding weaknesses provides specific targets for intervention.
    • Guiding intervention planning: The assessment provides the crucial information I need to develop an individualised intervention plan. The findings directly inform the selection of therapy goals, strategies, and techniques. Without a thorough assessment, therapy would be a shot in the dark.

    A multi-faceted approach

    A speech and language therapy assessment is not a ‘one-size-fits-all’ procedure. The specific tools and techniques used will vary depending on a child’s age, the nature of the suspected difficulty, and other relevant factors. However, most comprehensive assessments incorporate several key components:

    • Case history: This involves gathering information about your child’s developmental, medical, social, and educational background. We will go through all the relevant milestones and throughout the process I will make notes which will help bring all the puzzle pieces together.
    • Observation: I will observe how parent and child play together and we also look at how the child plays by themselves. Additionally of interest is how a child plays with me, the therapist. Through discussion I will also endeavour to find out how your child plays with other children, be it at the nursery or within the family.
    • Standardised assessments: These are commercially available tests with specific administration and scoring procedures. They provide norm-referenced data, allowing to compare the individual child’s performance to that of his or her peers. Examples include articulation tests, language comprehension and production tests, and fluency assessments. I tend not to use these assessments a lot.
    • Instead, I use non-standardised assessments: These are more flexible and allow to probe specific areas of concern in more detail. This might include language samples (analysing spontaneous speech), dynamic assessment (testing and teaching to identify learning potential), and informal observation of play or interaction.
    • Immediate feedback and report writing: During and thenfollowing the assessment, I will bring all the gathered information together and I will discuss with the parents what my findings are and what my recommendations in the short term are. Parents always go home with a good handful of useful strategies that they can implement at home right away. In addition, I provide a comprehensive report outlining the findings, diagnosis (if applicable), severity, strengths and weaknesses, and recommendations for intervention.

    In conclusion, a speech and language therapy assessment is a dynamic and essential process. It is a journey of discovery, aiming to understand a child and the child’s family and his or her unique communication or feeding profile. The assessment is usually the start of our wonderful learning journey together.

    Below is a short video clip of an assessment where you see me in action explaining a particular therapy approach to a set of parents. It perhaps shows a tiny bit of how relaxed we are in our sessions and that assessment is not at all daunting, but a hugely informative event overall which will leave you feeling empowered and hopeful.

    What happens after an assessment?

    Please feel free to get in touch with me via my contact form if you wish to have an assessment for your child’s communication difficulties or feeding difficulties.

    An assessment is always a stand-alone event and does not mean you need to automatically book follow up sessions at all. It will give a lot of information and based on this you can decide if you would like more therapy or follow up for you and your child. Many times ongoing therapy is not needed! I only recommend a course of therapy if it is really needed and where it would be immediately beneficial for your child.

    The power of imitation in supporting children with autism

    ByLondon Speech and Feeding
    Image by Freepik

    Imitation, the act of mirroring someone else’s actions, gestures, sounds, or words, is a fundamental skill that plays a crucial role in human development. It’s how babies learn to wave ‘bye-bye’, how toddlers pick up new words, and how children acquire social skills. But for children with autism imitation can be a significant challenge and understanding why it’s important and how to foster it becomes a key focus for parents, educators, and speech and language therapists.

    Why is imitation important?

    Imitation is a building block for a wide range of developmental skills:

    • Social interaction: Imitation is the foundation of social reciprocity. When a child imitates, he or she is engaging in a shared experience, connecting with another person, and learning to take turns in social exchanges.
    • Communication development: Imitation is closely linked to language acquisition. Children often imitate sounds and words before they can produce them independently. Imitation also helps them understand the meaning of gestures and facial expressions, which are vital for nonverbal communication.
    • Cognitive development: Imitation plays a role in problem-solving, learning new skills, and understanding cause and effect. By imitating actions, children explore their environment and learn how things work.
    • Emotional development: Imitation helps children understand and share emotions. When a child imitates a smile, he or she may begin to understand the feeling of happiness.

    Imitation challenges in autism

    Many children with autism face challenges with imitation, which can affect their development in these key areas. These challenges can manifest in different ways:

    • Difficulty imitating motor actions: Children with autism may struggle to imitate simple motor movements, such as clapping hands, waving, or playing ‘peek-a-boo’.
    • Limited vocal imitation: Imitating sounds, words, and phrases can be difficult for some children with autism, which can impact their speech development.
    • Challenges with social imitation: Imitating social cues, such as facial expressions, gestures, and body language, can be particularly challenging for children with autism, affecting their ability to engage in social interactions.

    Why do children with autism struggle with imitation?

    The exact reasons for imitation difficulties in autism are complex and not fully understood. However, several factors may contribute:

    • Neurological differences: Research suggests that differences in brain structure and function, particularly in areas involved in social perception and motor control, may play a role.
    • Sensory processing differences: Some children with autism may have sensory differences that make it difficult to attend to and process the movements or sounds they are expected to imitate.
    • Attention and motivation: Challenges with attention, focus, and social motivation can also affect a child’s ability to engage in imitation.

    How to foster imitation in children with autism

    Fortunately, imitation skills can be developed and improved through targeted interventions and strategies. Here are some approaches that I use in my practice as a speech and language therapist working with autistic children and their families:

    • Create a playful and engaging environment: Children are more likely to imitate when they are having fun and feel motivated. I use toys, games, and activities that the child enjoys.
    • Start with simple imitation: Begin by imitating simple motor movements that the child is already capable of and gradually introduce more complex actions.
    • Imitate the child first: As the Hanen Program emphasises, imitating the child’s actions, sounds, and words can encourage him or her to interact and communicate more.
    • Use visual supports: Visual aids, such as pictures, photos or videos, can help children with autism understand what is expected of them and make imitation easier.
    • Break down complex actions: Divide complex actions into smaller, more manageable steps. For example, to teach a child to brush their teeth, break it down into steps like ‘pick up toothbrush’, ‘put toothpaste on brush’, and ‘move brush on teeth’.
    • Reinforce imitation attempts: Provide positive reinforcement, such as praise, smiles, or preferred activities, when the child attempts to imitate, even if the imitation is not perfect.
    • Integrate imitation into daily routines: Incorporate imitation into everyday activities, such as imitating sounds during playtime, imitating gestures during songs, or imitating actions during self-care routines.

    The role of speech therapy

    Speech-language therapists play a crucial role in helping children with autism develop imitation skills, particularly in the areas of vocal and verbal imitation. As part of my therapeutic role, I offer the following:

    • Assessing a child’s imitation abilities.
    • Developing individualised therapy plans to target specific imitation goals.
    • Using a variety of techniques to encourage vocal imitation.
    • Working with parents and caregivers to provide strategies and support for promoting imitation at home.

    Summary

    Imitation is a fundamental skill that is essential for social, communication, cognitive, and emotional development. While children with autism may face challenges with imitation, it is a skill that can be developed and improved with targeted interventions and support. By understanding the importance of imitation and using effective strategies to foster it, parents, educators, and therapists can make a significant difference in the lives of children with autism, helping them to connect with others, learn new skills, and reach their full potential.

    Rethinking the PECS Approach

    ByLondon Speech and Feeding

    I want to talk about some concerns of SLTs, parents and increasingly autistic adults who explain to us how this communication method did not really work so well and why.

    What is PECS in a nutshell:

    PECS (Picture Exchange Communication System) is based on the idea of exchanging pictures in return for desired items. For more advanced users, it is used to communicate different functions such as emotions, comments, negations using the exchange of a sentence strip. It was founded on the principles of Applied Behavioural Analysis (ABA).

    How does that look in practice?

    In my experience, having been trained in the approach myself, the overall aim is eventually for the child to spontaneously go and get their picture book (PECS book), open it, look through a range of pages to select the correct picture of what they want to have or say, then go and find their communication partner, and finally place that picture onto the communication partner’s outstretched palm to be rewarded with an item or with a response of some sort. Or the child selects a range of pictures to create a little sentence, such as: ‘the blue fish swims in the sea’, ‘the red bird flies in the sky’ or ‘I see a red bird’ for example. This can be part of a structured table top activity.

    The system follows a series of phases, starting from simple picture exchanges to eventually construction of sentences using symbols. PECS’s aim is to promote communication initiation and reduce frustration for those who struggle with speech.

    So far so good one might say, why not? Before I go into the various concerns, I would want to add my own working experience with PECS, and whilst it is my opinion, I would say I have NEVER seen a working PECS book being used spontaneously!

    My experience

    I have seen attempts of stages 1 and 2 done quite well, in schools, and where people knew that I was coming in “to have a look at how PECS is working with child X”. Yes, in those instances an effort was made of course to try and show me how it worked. I must add that have never been very impressed. I cannot recall it used for any other items than: biscuits/quavers/crisps/ raisins and bubbles/puzzle pieces or spinners.

    If we want to see a child trained to exchange for these items in a structured setting, i.e., the child sits at a little table with the adult sitting opposite enticing the child with one or other item, then yes that can be done successfully. I have seen children exchange 25 pictures with a crisp on it, for said crisp and they might have asked for another 25 of those crisps given half the chance. Yes. Good. But. I have yet to see a child go to their PECS book and go through all the motions that I mentioned above to get a crisp. In school they don’t need to: they know that crisps are only available when the PECS book is being practised. Otherwise, let’s be honest, it’s fruit at 10.30 am!

    So, they don’t get a spontaneous opportunity to ask for highly motivating items as that is not how school works, is it? ‘SIR! Can I have a crisp?’ At 10.02am, in the middle of maths? Didn’t think so… So in reality this does not get practised in my experience.

    A few concerns in no particular order:

    Limited Generalisation

    One issue often raised is the limited generalisation of skills learned through PECS. The structured nature of the program may result in a child only being able to communicate effectively within the specific contexts where they were taught to use the system (as I suggest above: crisps: yes, please let’s do the PECS for it). This limitation can pose challenges when trying to apply communication skills in new or unstructured/spontaneous situations.

    Lack of Spontaneity

    Critics suggest that PECS can sometimes lead to scripted and less spontaneous communication. This is also what I have observed. Since the method is designed to follow a structured progression, there is a concern that individuals might struggle to initiate communication outside of the established framework, potentially hindering their ability to engage in more natural interactions.

    Narrow range of communication functions being practised

    While PECS is quite successful in focusing on requesting and naming items, there are many other important communication functions, such as expressing emotions, asking questions, giving opinions or greetings for instance. We can argue that a communication core board where we have a whole range of different core words available lends itself much better to practising a range of communicative functions.

    The Pictures are movable

    They are attached to the book via Velcro. They are constantly being picked and exchanged and then returned to the book. This means that the pictures tend to be always in different places. This goes against the motor planning that takes place when one is learning a new skill: imagine you want to learn to touch type and the letters always move and are at different places? How can you be quick about finding a letter? You can never get to “automatic” with this type of approach.

    Communication is not taught via behavioural means

    Only if you say “banana” in the way that I dictate that you should will you get a piece of banana. Who does that? Nobody. Typically, child points to the counter where there is a banana and says: ‘ba’ or ‘ana’ and mother/carer will look over there and say ‘oh banana! You want a banana? Ok there you go have a piece.’ Or something like it. Mother will not say: ‘SAY BANANA or else you won’t get it.’ Child hears mum saying ‘Banana’ each time and with time will point and say ‘banana’ or ‘I want-a-nana’ or something. This is how communication is learned: through the adult modelling it cheerfully all day long and the child hearing it and then gradually copying it.

    One other gripe I personally have but I am reliably informed by all my parents that they share this about PECS:

    IT IS SO LABOUR INTENSIVE!

    There are 10, 50, 100’s of little pictures that first of all need laminating… then velcroing, then finding and replacing. As I said above, it’s a constant moveable feast for one, but also you LOSE them. Yep. You want to find the picture for “trampoline”. ‘Where is it? I saw it yesterday… We had it outside when we practised you asking for the trampoline. I am sure we put it back? Where is it??? Ok. We need to print off a new one.’

    It is also labour intensive for the first stage where you need to have TWO adults to ease the exchange (pick up and release of picture into the communication partner’s hand). Who has two adults available for what can be weeks until the child is able to pick up and release by themselves?

    YEP. So it’s really not for me you can tell! I much prefer Core boards (see my previous post on using one) or electronic speech generating AAC devices like GRID, or LAMP or TOUCHCHAT. These are all great to use and there is good support out there for introducing these.

    Finding a Balance

    While the concerns surrounding the PECS approach are valid, it’s fair to note that the method also has some merits. There is anecdotal evidence of many individuals who have successfully improved their communication skills and quality of life through PECS. But, finding a balance between using PECS as a stepping stone and ensuring the development of more comprehensive and SPONTANEOUS communication is key.

    As educators and therapists, we need to extend the focus beyond requesting and labelling by incorporating symbols that represent emotions, actions, and more complex ideas. This expansion encourages a broader range of communication functions. When the time is right, gradually transitioning from PECS to more advanced communication methods such as Core boards or electronic AAC tools and speech-generating devices is the way forward.

    We want to value all communication equally and our approach ought to be playful and child-led and to focus on intrinsic motivation instead of extrinsic rewards and reinforcers.
