Sensory hyper- and hypoactivity

Sensory hyperactivity and hypoactivity are crucial aspects of life for children with autism. These sensory challenges can have a significant impact on their well-being and quality of life.

In this session, we will explore in depth what sensory hyper- and hypoactivity are, how they manifest in children with autism, and how caregivers, therapists, and educators can effectively address these challenges.

Defining Sensory Hyper- and Hypoactivity

Before delving into the topic, it is important to understand what sensory hyper- and hypoactivity mean:

• Sensory Hyperactivity: Sensory hyperactivity involves a hypersensitivity to sensory stimuli, such as bright lights, loud noises, unpleasant textures, or intense smells. Children with autism who experience sensory hyperactivity may overreact or become overwhelmed to these stimuli, which can lead to avoidance behaviors or meltdowns.

• Sensory Hypoactivity: On the other hand, sensory hypoactivity refers to a decreased sensitivity to sensory stimuli. Children with autism who experience sensory hypoactivity may not respond appropriately to stimuli, such as pain, cold, or touch, which can lead to a lack of danger perception or the seeking of intense sensory stimulation.

Manifestations of Sensory Hyperactivity in Children with Autism

Sensory hyperactivity in children with autism can manifest in a variety of ways:

• Sensitivity to noise: Everyday sounds, such as the ringing of a telephone or the noise of a hair dryer, can be unbearable for some children with sensory hyperactivity. This can lead to extreme responses, such as covering their ears or retreating to a quieter place.

• Light sensitivity: Sensory hyperactivity can make bright light uncomfortable or painful for some children with autism. Wearing sunglasses indoors or avoiding bright light are common strategies.

• Touch sensitivity: Textures, such as the label on a T-shirt or the feel of certain fabrics, may be uncomfortable or even painful for children with sensory hyperactivity. They may prefer loose clothing and avoid certain textures.

• Sensitivity to smells and tastes:Some children with autism may have an aversion to strong or foreign smells and tastes. This may influence their food preferences and reaction to certain environments.

Manifestations of Sensory Hypoactivity in Children with Autism

Sensory hypoactivity can also be a significant challenge for children with autism:

• Stimulation Seeking: Children with sensory hypoactivity may actively seek sensory stimulation, such as rocking, rolling over, or pressing objects forcefully. This stimulation seeking can be dangerous in some situations.

• Lack of response to pain or temperature: Children with sensory hypoactivity may not react to pain or hot/cold in the way that would be expected. They may not realize they have been hurt or may not show discomfort to extreme temperature changes.

• Need for intense stimulation: Some children with sensory hypoactivity may seek intense stimulation, such as biting themselves or head banging. This can be a form of self-regulation, but it can also be harmful.

Strategies for Addressing Sensory Hyper- and Hypoactivity

It is critical for caregivers, therapists, and educators of children with autism to understand and address sensory hyper- and hypoactivity effectively. Here are some key strategies:

• Professional Assessment: A health care professional specializing in autism can conduct a sensory assessment to understand the child's specific needs. This can help develop a tailored intervention plan.

• Environment modification: Making adjustments to the child's environment, such as reducing bright lighting or providing quiet areas, can help minimize sensory hyperactivity.

• Occupational therapy: Occupational therapy can be invaluable in helping children with autism develop self-regulation and coping skills in response to sensory stimuli.

• Communication support: Helping children communicate their sensory needs is crucial. They can learn strategies for expressing their sensations and needs, allowing them to seek support or avoid overwhelming situations.

• Establishing routines and structure: Structure and predictability can help children with autism cope with sensory challenges. Knowing what to expect can reduce anxiety.

• Respect individual preferences: Recognizing and respecting individual sensory preferences and needs is essential. What may be intolerable to one child may be comforting to another.

• Education and awareness: Providing information to people who interact with the child, such as classmates or family members, can foster understanding and empathy toward sensory challenges.
