Sensory inputs can be any stimuli
entering through one of the sensory
modalities: sight, sound, gustation,
olfaction, and tactile sensations.
Tactile sensations include responses
to pressure and temperature. Over
stimulation is the product of sensory overload.
Overstimulation (OS) occurs when there is āto
muchā of some external stimulus or stimuli for
a person's brain to process and integrate effectively.
Sensory overload can be triggered by a singular
event or a build up thereof. When the brain has to put
all of its resources into sensory processing, it can shut
off other functions, like speech, decision making and
information processing.
Using noise-cancelling headphones to vastly reduce
external sound, which can help to stop sensory over
load. Weighted sensory products, such as blankets
or vests, to provide pressure and soothing proprioceptive
input. Avoiding open questions ā if you need their input on
something, aim to use closed yes/no questions.
It causes feelings of discomfort and being overwhelmed.
Moving away from sources of sensory input, such as loud
sounds or strong smells, can reduce these feelings.
However, it is a core characteristic of autism, where individuals
often experience heightened sensitivity to stimuli.
It's important to note that not all autistic individuals experience
overstimulation in the same way or to the same degree. Some
may have a higher threshold for sensory input and be less easily
overwhelmed, while others may become overstimulated even in
relatively calm environments.
Stimming, short for self-stimulating behaviors, is a
repetitive movement or action that can include body
movements, vocal noises, or sensory stimulation. It
can be a way to manage excess energy, self-soothe,
or cope with emotions. Stimming can also help regulate
sensory input, either increasing stimulation or decreasing
sensory overload.
Stimming behaviors can consist of tactile, visual, auditory,
vocal, proprioceptive (which pertains to limb sensing),
olfactory, and vestibular stimming (which pertains to balance).
