Have you ever recoiled from a loud, unexpected noise or found comfort in a familiar scent? These are examples of sensory processing – the way your brain interprets and responds to information from your environment. But what happens when this process goes awry? This article will delve into What Is Spd, exploring its impact and offering insights into understanding this often-misunderstood condition.
Defining Sensory Processing Disorder (SPD)
Sensory Processing Disorder (SPD) occurs when the brain struggles to process sensory signals effectively. This can lead to either hypersensitivity (over-responsiveness) or hyposensitivity (under-responsiveness) to various stimuli. While many people have sensory preferences or dislikes, individuals with SPD experience chronic difficulties that significantly disrupt their daily lives. For example, someone with SPD might not just be startled by screeching tires; they might experience overwhelming anxiety, requiring noise-canceling headphones in similar environments.
It’s important to note that while SPD isn’t a formal medical or psychiatric diagnosis in all regions, recognizing sensory processing issues is crucial for understanding individual behaviors and providing appropriate support and accommodations.
The Connection Between SPD and Autism

SPD is frequently observed as a co-occurring condition with Autism Spectrum Disorder (ASD). In fact, sensory sensitivities are incorporated into the diagnostic criteria for ASD. However, it’s crucial to remember that not everyone with SPD has autism.
Research indicates that individuals with autism often exhibit altered neural connectivity, which may contribute to challenges in processing and organizing environmental stimuli. Sensory information may be processed atypically, with responses varying based on the environment and context. This unique processing can make it difficult for autistic individuals to react to sensory stimuli in socially expected ways.
SPD Manifestations in Autistic Individuals
SPD can influence repetitive behaviors and strengths like attention to detail often seen in autistic individuals. Responses to external input can manifest in several ways:
- Over-responsive reactions: An exaggerated response to sensory stimuli.
- Under-responsive reactions: A lack of response to sensory cues or apparent disinterest in stimuli.
- Sensory-craving reactions: A constant need for sensory stimulation, potentially involving touching, movement, or seeking out loud noises, sometimes with a lack of awareness of personal boundaries.
Those who seek sensory stimulation might stand close to others, seemingly unaware of personal space, engage in atypical physical activity, or seek out loud noises. Conversely, individuals who avoid sensory stimulation may be easily distracted by background noise, avoid being touched, or restrict themselves to specific foods or clothing.
When overwhelmed by external stimuli, autistic individuals may engage in hyperfocus, sensory-seeking, or self-stimulating (stimming) behaviors like fidgeting, tapping, arm flapping, or making soothing noises. Sensory overload can lead to distress, panic attacks, anxiety, nausea, or tension.
It’s essential to recognize that while many autistic individuals display certain behaviors related to sensory issues, not all will meet the criteria for SPD.
Common Symptoms of Sensory Processing Disorder
- Increased movement, such as jumping, spinning, or crashing into things.
- Increased stimming, such as hand flapping, making repetitive noises, or rocking.
- Talking faster and louder, or not talking at all.
- Covering ears or eyes.
- Difficulty recognizing internal sensations like hunger, pain, or the need to use the bathroom.
- Refusing or insisting on certain foods or clothing items.
- Frequent chewing on non-food items.
- Frequent touching of others or playing rough.
- Difficulty communicating or responding as the brain shifts resources to deal with sensory input (shutdown).
- Escalating, overwhelming emotions or the need to escape a situation (meltdown).
Impact of SPD on Autistic Individuals
SPD can significantly impact social interaction. An autistic person experiencing SPD might struggle to focus on a conversation or activity if the environment is overwhelming due to bright lights, loud noises, or the absence of noise. These situations can be overwhelming, diminishing the rewarding aspects of social interaction. Consequently, some autistic individuals prefer less stimulating environments and activities that require less social interaction.
Sensory processing disorders can also disrupt an autistic person’s ability to focus on a task or conversation for extended periods. The sensory issue becomes all-consuming, requiring learned supports or accommodations to manage. Fidget devices can redirect focus away from unpleasant sounds, while adjusting lighting can improve concentration.
Diagnosis, Interventions, and Coping Strategies for SPD
While SPD isn’t universally recognized as a formal diagnosis, various supports and accommodations can significantly improve quality of life. Occupational therapists and physical therapists play a crucial role in developing coping skills, including:
- Assistive Technology: Weighted vests, fidget spinners, speech-generating devices, and other tools can provide multi-sensory reinforcement.
- Environmental Modifications: Dimming lights, scheduling sensory breaks, removing visual distractions, and preferential seating arrangements can minimize distractions and enhance focus.
- Sensory Integration Therapy (Sensory-Focused Interventions): Activities like swinging, spinning, deep pressure exercises, visual stimulation, and therapeutic listening can reduce distress and promote adaptive responses.

Tips for Educators
Creating an inclusive classroom environment for autistic students with SPD requires specific considerations:
- Consistency: Maintain a consistent environment, considering sensory needs when rearranging the classroom or decorating.
- Structure and Predictability: Provide clear structure and detailed information about potentially overwhelming events like recess, field trips, or assemblies, along with support systems.
- Environmental Sensory Issues: Address flickering lights, central air noise, or class bells, modifying them as needed.
- Multi-Modal Instructions: Offer directions and instructions in various formats, including written, visual, and verbal.
- Education and Awareness: Educate school staff about the challenges associated with SPD to foster an inclusive environment and prevent bullying.
Guidance for Caregivers
Supporting an autistic individual with SPD requires empathy and understanding:
- Empathy and Patience: Recognize that sensory processing issues may not be intuitive for you.
- Validation: Trust that their experiences are genuine, even if you don’t fully understand them.
- Professional Support: Seek guidance from sensory integration-trained occupational or physical therapists who can use sensory stimulation with physical movement to improve sensory processing.
By understanding what is SPD and its impact, we can create more supportive and inclusive environments for individuals with sensory processing differences.
