The signs of sensory processing differences

In this article I describes some common signs of sensory issues.  You might relate to these behaviours if you or your child experiences Sensory Processing Differences.  I’ll explore common examples of children (and adults) who experience sensory differences and provide the following SPD checklists:

The signs of sensory processing differences

In this article I describes some common signs of sensory issues.  You might relate to these behaviours if you or your child experiences Sensory Processing Differences.  I’ll explore common examples of children (and adults) who experience sensory differences and provide the following SPD checklists:

  • Sensory Processing Disorder Checklist – Signs and symptoms of Sensory Processing Disorder

  • Symptoms and Signs of Sensory Issues Checklist – Sensory Modulation Challenges

  • Signs of Sensory Issues in Children – Motor Skill Challenges

If you haven’t read my article  ‘What is Sensory Processing Disorder?’, I recommend that you do before continuing.  The article gives background to sensory processing and sensory integration.  It describes the different sensory processing issues people may experience.

It is estimated that between 5-16% of children and adults experience sensations differently. People who show signs of sensory issues interpret sensory information differently to those who do not. Their brains do not connect the sensory messages they receive from their body in the same way as others.  This creates a different sensory experiences and can make some environments or activities more challenging or overwhelming to be in.

Their response to sensory information is not always what you might expect. You must always remember that their responses are not right or wrong. They are just different from your own.

It is important to remember that although you may not be experiencing the sensation as a challenge, someone else will have a different experience.  Their interpretation is not right or wrong, it is just how their brain perceives the sensory information.

What are the common signs of sensory issues?

Signs there might be a sensory issue, for both children and adults, may include:

  • Being sensitive to sensory information (over-responding or hyper-responsive)

  • Being slow to notice or being oblivious to sensory information (under-responding or hypo-response)

  • Looking for more sensory information (sensory seeking or craving)

  • Finding it difficult to plan and organise their movement (dyspraxia)

  • Having poor balance and being clumsy (poor postural control)

  • Having poor awareness of the qualities of sensory information (discrimination)

Occupational therapist Lucy Miller (2014) describes these symptoms under the headings of modulation, sensory-based movement and discrimination.  Children (and adults) with Sensory Processing Disorder (SPD) could experience a combination of sensory processing challenges or may also only have sensory issues in one area. It is important to remember that even though the term is frequently used, SPD is not a formally recognised diagnosis.  Kim explores the sections of Lucy Miller’s model in more depth here.

How could sensory issues present?

Signs of sensory issues vary depending on which sensory system is affected.  This is why Sensory Processing Disorder can look very different from one child (or adult) to the next.  Each child’s (or adult’s) brain is connecting the sensory messages differently.  This, therefore, results in different reactions and behaviours.  We must always remember that behaviour is only the end product.  It is a clue to us that the child or adult may be finding the sensory information difficult to manage or maybe coordinate.

Jessica’s story – sensitivity

Brushing her hair; cutting her hair and nails; wearing socks: Jessica hates them all! Even clothes causes distress. Many fabrics are itchy. The collar on her school shirt irritates her.  These can be signs of sensory issues, specifically touch sensitivity.

When she was younger, Jessica found loud or unexpected sounds felt overwhelming. Unexpected touch also alarms her. Once, she hit a child who brushed past her in the playground. Now she always tries to go to the sick room at lunch to avoid feeling overwhelmed by noise and touch.

Another thing Jessica hates is swimming. Putting her head under water is scary. Jumping in is just terrifying! In fact, learning any new activity is tough for Jessica because planning and organising herself is difficult.

Jessica processes sensory information differently

Her brain is interpreting the touch input from brushing her hair and cutting her nails more intensely (and potentially more painfully) than other people do.

She finds certain noises unbearable. This stops her from being able to participate at lunchtime. It seems that Jessica’s brain is interpreting sound more intensely than others too.  This is a sign of auditory sensitivity.

Jessica presents as having difficulty with modulating touch and noise sensory inputs. Therefore, it is likely she has over-responsivity (sensitivity) in both touch and hearing.  There may also be some sensitivity with her vestibular system.

She finds learning new activities hard and struggles to plan and organise. Some sensory messages from her body aren’t connecting smoothly to allow her to join in. This could mean she also has dyspraxia.

Signs of Sensory Issues – SPD Symptoms and Checklists

As I outlined on the What is SPD? page, unfortunately, SPD does not yet formally exist as a stand-alone diagnosis.  Many of the challenges and behaviours we list in these checklists occur alongside other conditions.  It is important to remember every child (or adult) who experiences sensory issues is different.  There is no one size fits all.  This also means there is not one treatment strategy that fits all.  It is hoped that these checklists provide a starting point for you to consider if a behaviour might be linked to an underlying sensory issue.  We always recommend you seek out extra support from professionals rather than using these lists to self-diagnose.  In addition, we recommend you look at the additional resources and references below for more information.

This table gives examples of behaviours you might observe for the different types of responses.  Use the tabs to look at the different responses.  There are also sensory checklists at the bottom which you can also download.

Harry’s story – a mixed pattern of processing

Like Kayla, Harry dislikes loud sounds. If the projector is on in his classroom, it’s all he can focus on. The humming sound it makes means it’s impossible for him to concentrate on his work.

Sluggish to get going during PE, he often trips up and loses balance. Tiring really quickly, he always comes last.

Breaking things accidentally at school and home is normal for Harry. When he plays with his younger sister, his mother is always telling him to ‘be more gentle’.

Harry’s sensory differences

Harry also processes sensory information differently to others. These sensory processing issues suggest that he also has difficulty with sensory modulation.

Harry finds noises, including background noises, harder to ignore. His brain just seems to keep focusing on them rather than what he should be thinking about. For this reason, it seems likely that he has some sound sensitivity.

Harry frequently gets in trouble for being too rough in play and breaking things. Losing balance is common. His vestibular and proprioceptive senses need more sensory input for him to understand what’s going on with his body. These signs of sensory issues suggest that, unlike Kayla, his vestibular and proprioceptive senses are under-responsive and that he has difficulties discriminating proprioceptive input. Furthermore, Harry appears to have poor postural control too.

It is really common for children to have sensory challenges in more than one area of sensory processing.  The SPD checklists below provide more information.  They help to answer the question ‘What are common sensory issues?’ and explore sensory processing disorder symptoms.

How can I get help if I think myself or my child has Sensory Processing Disorder?

The best professional to help identify if your child has sensory processing challenges is an occupational therapist who has additional training in sensory integration.

For families based in the UK and with children aged between 5-12, Kim is now offering online children sensory assessments.  In 2024, she also launched assessments for adults based in the UK, which includes the option for a workplace assessment in London and the Home Counties.

Where can I find more information about signs of sensory issues or the symptoms of SPD?
