What is The Tactile System in Children

Occupational Therapy
Written By Kimberley Arnett-DeSimone

What is the tactile system in children? In the early stages of life, the development of sensory systems plays a pivotal role in shaping a child’s ability to interact with the world around them. Among these systems, the tactile system, responsible for processing touch and pressure sensations, is particularly significant in children’s growth and development. This article will examine the anatomy, developmental milestones, and the implications of a healthy tactile system for a child’s physical, cognitive, and emotional development.

Anatomy of the Tactile System in Children

The tactile system in children is remarkably similar to that in adults, consisting of sensory receptors, nerve pathways, and central processing areas. Understanding the anatomy of the tactile system in children is crucial to grasp its influence on their development.

Sensory Receptors: In children, sensory receptors detect and transmit tactile information. These receptors are distributed throughout the skin, and children have a heightened density compared to adults. These receptors allow children to explore the world through touch and feel, helping them understand their surroundings. The primary sensory receptors involved in touch perception in children are similar to those in adults and include Merkel cells, Meissner’s corpuscles, Ruffini corpuscles, and Pacinian corpuscles.


Nerve Pathways: The neural pathways that transmit tactile information from the receptors to the central nervous system (CNS) are well-developed in children. Their peripheral nerves, such as those in the hands and fingers, relay information to the spinal cord and brain.


Central Processing: Just like in adults, the sensory information collected by the tactile system in children is processed by the central nervous system. The development of the somatosensory cortex, located in the brain's parietal lobe, allows children to interpret and perceive tactile sensations. This enables them to recognize various qualities of touch, including temperature, pressure, and texture.

Developmental Milestones and the Tactile System

The tactile system plays a vital role in various developmental milestones in children. It contributes to their physical, cognitive, and emotional growth from infancy through childhood.

Early Exploration: Infants are born with an inherent curiosity to explore their environment. The tactile system facilitates this exploration by allowing them to touch and feel objects, people, and surroundings. Babies often put objects in their mouths, grasp items, and experience different textures through their sensitive skin, helping them learn about the world.


Fine and Gross Motor Skills: The tactile system is closely linked to developing fine and gross motor skills. It enables children to refine their grasp and release movements, improving their hand-eye coordination. Fine motor skills, such as picking up small objects and scribbling with crayons, rely heavily on tactile feedback to develop precision and dexterity.


Cognitive Development: Tactile experiences enhance cognitive development in children. When manipulating objects with varying shapes, sizes, and textures, they gain a deeper understanding of spatial relationships and develop problem-solving skills. Tactile learning helps children internalize abstract concepts through concrete experiences.


Emotional Regulation: The tactile system plays a crucial role in emotional regulation in children. Touch and physical contact, like hugs and comforting touches from caregivers, stimulate the release of oxytocin, a hormone associated with bonding and stress reduction. A well-functioning tactile system can help children feel safe, secure, and emotionally connected.


Social Interaction: Tactile experiences are integral to social interactions and communication. Through touch, children express affection, empathy, and friendship. The tactile system contributes to developing social skills, such as recognizing non-verbal cues and understanding the emotional states of others.

Implications for Childhood Development

A well-functioning tactile system in children has profound implications for their overall development and well-being.

Enhanced Learning: Tactile experiences in early childhood education promote sensory-rich learning environments. Activities that engage the tactile system, such as sensory play with sand, water, or textured materials, can enhance a child’s learning experience by making abstract concepts more tangible and memorable.


Sensory Processing: Some children may experience sensory processing difficulties, where their tactile system is either overactive or underactive. Overstimulation or discomfort in response to touch can lead to sensory sensitivities, while under-responsiveness can affect a child’s awareness of their environment. Recognizing and addressing these issues through sensory integration therapy can help children overcome sensory challenges.


Emotional Well-Being: Positive tactile experiences contribute to a child’s emotional well-being by fostering a sense of security, comfort, and trust. A supportive and nurturing touch can significantly impact a child’s emotional development and resilience.


Motor Development: The tactile system is closely linked to a child’s motor development. Children who engage in activities promoting tactile exploration and manipulation, such as building blocks, finger painting, or playing with modeling clay, can develop better hand-eye coordination and fine motor skills.


Social Bonds: The tactile system is pivotal in forming social bonds between children and their caregivers. Physical contact, such as cuddling, hugging, and holding hands, fosters a strong emotional connection between children and their parents or caregivers, contributing to their emotional security and development.


The tactile system in children is a fundamental aspect of their growth and development. It influences physical, cognitive, and emotional milestones from infancy through childhood, allowing children to explore, learn, and form essential social bonds. Nurturing a child’s tactile system through sensory-rich experiences and supportive touch can have a profound and lasting impact on their development and overall well-being. Understanding the crucial role of the tactile system in children underscores the importance of creating environments that encourage tactile exploration and sensory-rich learning opportunities. By doing so, we can support and enhance the development of the next generation, helping children reach their full potential.

The traditional view of intelligence has often been narrow, focusing primarily on academic aptitude and standardized test scores. However, Howard Gardner's multiple intelligence theory revolutionized the way we understand human cognitive abilities. Gardner's theory suggests that there are several distinct types of intelligence, each with its unique characteristics and qualities. This paradigm shift has profound implications for education, as it recognizes the diverse ways individuals learn and excel. In this article, we will explore Gardner's theory of multiple intelligences and discuss its significant impact on learning.

The early years of a child's life are a time of remarkable growth and development. From the moment they are born, children begin a journey of learning and discovery, reaching important developmental milestones along the way. These milestones are key indicators of a child's progress in various areas of development, including physical, cognitive, social, and emotional. Understanding these milestones can help parents and caregivers ensure that a child is on track and provide the necessary support to foster healthy development. The following is meant to be a guideline. Infants and children develop at varying rates; however, if you are concerned that your child may have a significant delay, speak with your pediatrician and explore options for a formal developmental assessment by a professional.
