This page explains how tactile perception relates to touch perception, haptic perception and tactile discrimination.
The hands are an important source of sensory information, and the brain uses this input to guide hand movements during activities. Children who struggle to interpret this sensory information may struggle to develop their fine motor skills. Find out how to support your child!
Using a variety of sensory receptors, the skin registers sensory information and sends it to the brain.
The brain then processes this information to correctly understand (perceive) what is being touched/held and how it is being used.
The terms touch
perception, tactile perception and haptic perception are often used
interchangeably by teachers and therapists, yet each has a distinct
meaning.
Having good tactile perception and haptic perception can help a child use the hands effectively and helps to develop good fine motor skills.
When you shove your hand into your bulging handbag and fish around to retrieve your keys, your touch perception enables you to find your keys without looking.
Stop for a moment and think how it feels to wash the dishes or plant a seedling while wearing thick gloves.
The task is much more challenging because of the limited tactile feedback you are getting from your hands.
When you are not getting good sensory feedback from your fingers, it is hard to be accurate with them. You are more likely to be clumsy, and end up crushing the delicate plant roots or breaking the fragile crystal glass.
This can give you an idea of the struggles kids face when they have impaired touch perception. It's not that there's an issue with their hands; rather, the brain isn't processing the sensory information properly.
The brain uses the sensory feedback from the hands to guide what the hands do and how they do it. If the brain struggles to perceive what is being held, or how tightly it is being held, this can affect how the child uses the hands.
Remember, touch perception is about your brain understanding (perceiving) the sensory messages your hands send to your brain.
However if your child has sensory processing issues, this may affect the actual messages that are sent to the brain.
If your child seems to struggle with touch perception or sensory processing in any way, please do reach out to an occupational therapist who can help your child.

Tactile activities provide kids with overall sensory experiences that enable them to explore their world through touch.
Here are some ideas for tactile activities:
Tactile discrimination activities help kids learn to identify items by touching and feeling without looking at what the hands are doing.
These can help in developing the fine motor skills needed for daily tasks and for handwriting.
Whether indoors or outdoors, your child's touch perception will benefit from grasping, moving and playing with real life objects instead of playing on a flat, smooth screen.
