Sensory differences and stimming in autism are closely linked, as stimming often serves as a coping mechanism for managing sensory overload. Sensory processing challenges, such as heightened or diminished sensitivity to sights, sounds, or textures, are common in autism, and stimming can help individuals regulate these experiences. Stimming, or self-stimulatory behaviour, includes repetitive movements or sounds like hand-flapping, rocking, or humming. These repetitive behaviours are often a response to sensory input, helping individuals with autism manage overwhelming stimuli and emotions.

For many individuals, stimming provides a form of self-regulation, helping them focus, calm themselves, or block out excessive sensory stimuli. It allows individuals to create a sense of familiarity and control in otherwise overstimulating situations.

How Sensory Differences Relate to Stimming

Here’s how sensory differences and stimming in autism are connected:

Managing sensory overload

When individuals with autism experience overwhelming sensory input, such as loud noises or bright lights, stimming helps reduce anxiety by focusing attention on a repetitive behaviour. This helps the individual manage the sensory overload they are experiencing.

Self-regulation through stimming

Stimming serves as a way for individuals to regulate their emotional responses. It can help them calm their nervous system or alleviate stress, which is particularly useful in environments like schools or social settings where sensory input is constant and difficult to filter.

Repetitive behaviours as coping mechanisms

For many individuals, stimming offers a controlled way to process and manage their sensory experiences. It provides a predictable and manageable form of sensory input, allowing them to regain focus and control.
